A bathroom remodel is a lot like following a complex recipe. Each step builds on the last, and getting the sequence right is the secret to a beautiful result. You wouldn’t frost a cake before you bake it, and you shouldn’t install a vanity before the floor is tiled. Following the correct bathroom remodel order of installation is the single most important factor in keeping your project on time, on budget, and free from frustrating rework. This guide breaks down the entire process, from demolition to the final touches, into a clear, step-by-step timeline that professionals use to deliver flawless results every time.
Key Takeaways
- Focus on the Foundation First: The most critical work happens behind the walls. Ensure all plumbing, electrical, and waterproofing are completed and pass inspection before closing up walls and installing any visible finishes.
- Order Materials Before You Demolish: Avoid a stalled project by having all your key materials—especially custom items like vanities and tile—on-site before the first hammer swings. This is the best way to keep your timeline on track.
- Install Finishes from the Ground Up: To protect your new investments, install flooring and wall tile first. The vanity, toilet, and other fixtures should be set on top of the finished surfaces, with painting reserved as one of the final steps.
What’s the Correct Order for a Bathroom Remodel?
A successful bathroom remodel follows a specific sequence, much like a recipe. Each step builds on the last, and getting the order right is the key to a smooth project that finishes on time and on budget. Jumping ahead or doing things out of turn can lead to costly rework, damage to new materials, and a lot of unnecessary frustration.
Think of it as working from the inside out. The work behind your walls and under your floors has to happen before any of the beautiful finishes you’ve picked out can be installed. Following a proven method ensures everything fits together perfectly, from the plumbing you can’t see to the tile you’ll walk on every day.
An Overview of the Remodel Timeline
While every project is unique, a professional bathroom remodel follows a predictable path. After the design is finalized and materials are ordered, the physical work begins with demolition. Next, we focus on the “rough-in” stage, where new plumbing pipes and electrical wiring are installed inside the walls and floors. Once that passes inspection, we move on to closing up the walls, waterproofing, and preparing surfaces.
From there, it’s all about bringing the vision to life. Tiling for the shower and floors usually comes first to create a clean, waterproof foundation. Then, the vanity, toilet, and other major fixtures are carefully set in place. The final steps involve painting, installing faucets, lighting, and all the finishing touches that complete the space. This structured approach is a core part of our process.
Why the Order of Operations Matters
Following the correct sequence isn’t just about efficiency; it’s about protecting your investment. For example, installing tile before the vanity and toilet prevents water damage and protects your new cabinetry from the mess of cutting and setting tile. Completing all the messy work like drywall and sanding before painting ensures a flawless finish, free from dust and debris.
More importantly, this methodical approach minimizes risk. Professional teams follow a proven order for plumbing, electrical, and waterproofing to prevent leaks, ensure safety, and meet building codes. When you work in a logical order, you avoid having to undo completed work to fix an earlier mistake. This saves time, reduces material waste, and is the surest way to get the high-quality, lasting results you expect.
Phase 1: Plan and Prepare Before Demo Day
A successful bathroom remodel begins long before the first swing of a hammer. This initial phase is all about laying the groundwork for a smooth, predictable project. Getting the planning, permits, and materials sorted out upfront prevents costly delays and ensures the entire process, from demolition to the final walkthrough, runs like a well-oiled machine. Think of it as the “measure twice, cut once” stage of your renovation. Taking the time to prepare properly is the single best thing you can do to achieve the beautiful, functional bathroom you’ve been dreaming of with minimal stress.
Secure Your Permits and Inspections
Before any work begins, it’s essential to secure the necessary permits. This isn’t just about following rules; it’s about ensuring your remodel complies with local San Diego building codes for safety and structural integrity. Skipping this step can lead to major headaches, failed inspections, and even problems when you eventually sell your home. A reputable design-build firm will manage the entire permitting process for you, from submitting plans to scheduling inspections. This is a core part of our process, as it protects your investment and guarantees that all plumbing, electrical, and structural changes are done correctly and to code.
Order Materials and Schedule Deliveries
To keep your project on schedule, all your new materials should be ordered and, in many cases, on-site before demolition starts. Items like custom vanities, tile, and bathtubs can have long lead times, and waiting for a delivery can bring the entire project to a halt. Having everything ready streamlines the installation process for a seamless transition from one trade to the next. Visiting a design showroom early in the planning phase allows you to finalize selections, confirm availability, and place orders well in advance, preventing delays and ensuring your vision comes to life without a hitch.
Protect Your Home from Dust and Debris
A bathroom remodel can be messy, but it doesn’t have to disrupt your entire home. Proper preparation is key to containing dust and protecting your living spaces. This includes laying down protective floor coverings from the entry to the bathroom and sealing off the work area with plastic barriers. If you’re remodeling your only bathroom, you’ll also need a plan for where to shower and get ready. At King Remodeling, we treat your home with respect. Our teams are committed to daily cleanup and jobsite protection because we believe a great remodel includes a great experience. It’s a standard of care that reflects who we are as a company.
Phase 2: Demolition and Discovery
This is where the transformation truly begins. Demo day is exciting, but it’s also the moment of truth. Once the old tile, vanity, and fixtures are gone, we get a clear look at the underlying structure of your bathroom. This “discovery” phase is critical because it reveals the true condition of your walls, subfloor, and plumbing. While it can sometimes uncover challenges, having an experienced team on-site means we can pivot quickly and solve problems without derailing the timeline.
Our crews take great care to isolate the work area, protecting the rest of your home from dust and debris. We handle the entire tear-out process, from carefully disconnecting plumbing to hauling away the old materials. This phase clears the way for a clean slate, ensuring the new bathroom is built on a solid, sound foundation. It’s less about brute force and more about a strategic, careful deconstruction that sets the stage for everything to come. You can see how we manage this phase in our featured projects.
Safely Remove Old Fixtures and Finishes
Removing old bathroom components requires a specific sequence to prevent water damage and ensure safety. The first step is always to shut off the main water supply to the bathroom. From there, our team will typically drain and remove the toilet, which gets it out of the way and prevents messy leaks. Next, we tackle the vanity, sink, and any bulky cabinetry.
If you have a tub or shower surround, we’ll carefully remove the tile or panels to access the plumbing connections before taking out the unit itself. The final step is usually removing the old flooring to expose the subfloor. Throughout this process, we work methodically to deconstruct the space, preserving any structural elements and ensuring a clean, prepped canvas for your new bathroom remodel.
Address Hidden Damage or Structural Surprises
Even with meticulous planning, demolition can reveal unexpected problems hiding behind walls and under floors. The most common culprits are water damage, mold, or outdated plumbing and electrical systems that don’t meet current building codes. This is a normal part of any major remodel, and it’s exactly why the discovery phase is so important.
Finding these issues early allows us to address them properly before installing new materials. Our project managers will communicate any findings with you immediately, explaining the issue and outlining a clear plan to resolve it. Having an experienced design-build team means we have the in-house expertise to handle these surprises efficiently, from structural repairs to plumbing updates, keeping your project moving forward.
Key Safety Tips for Demolition
A safe demolition is a successful demolition. Our crews always prioritize safety by wearing the proper personal protective equipment (PPE), including gloves, eye protection, and masks. We use specialized tools designed for deconstruction, which are more effective and safer than simply swinging a sledgehammer. For example, we use specific saws for cutting through materials like insulation to minimize airborne particles.
Beyond personal safety, we focus on protecting your home’s structural integrity. We carefully assess which walls are load-bearing and ensure all electrical circuits are shut off before any work begins. This professional approach is a core part of our process and ensures that the demolition phase is clean, controlled, and sets a safe foundation for the beautiful new bathroom to come.
Phase 3: Rough-In Your Plumbing and Electrical
With the old bathroom gone and the framing exposed, it’s time to map out the new functional core of your space. The “rough-in” phase is all about installing the systems that work behind the scenes: your plumbing, electrical, and ventilation. This work happens before the drywall goes up, making it the perfect time to move a shower head, add an outlet next to the vanity, or install a more powerful exhaust fan.
Because this stage involves complex systems with strict safety codes, it’s one of the most important times to have licensed professionals leading the charge. Getting the plumbing and electrical right is fundamental to a safe, functional, and lasting bathroom remodel. A design-build team manages all the licensed plumbers and electricians, ensuring every pipe and wire is placed correctly according to your approved design plan and local building codes. This coordination prevents mistakes that could lead to leaks, electrical hazards, or failed inspections down the road.
Install New Plumbing Lines
First, our licensed plumbers get to work installing the new water supply and drain lines. If your new layout involves moving the toilet, vanity, or shower, this is when we run new pipes to their exact locations. We’ll install the new shower valve inside the wall—the part that controls your water temperature and pressure—and set the tub or shower pan in place. We also run the vent pipe for your new, quieter bathroom fan, making sure it properly exhausts moisture to the outside of your home, not just into the attic.
Run Electrical Wiring and Update HVAC
Next, electricians run all the new wiring for your bathroom’s lighting, outlets, and switches. This includes dedicated circuits for things like heated floors or a high-powered vanity light. We’ll place junction boxes for sconces, overhead lights, and that new fan. This is also the perfect time to add modern conveniences, like an outlet inside a vanity drawer for your hair dryer or an extra GFCI outlet for safety near the sink. Proper electrical work is critical for safety and function, and our team ensures everything is installed to code.
Pass Your Rough-In Inspections
Before any walls can be closed up, a city inspector must visit the site to approve the rough-in work. This is a non-negotiable step in any permitted remodel. The inspector will verify that all the new plumbing and electrical installations meet San Diego’s building codes, ensuring your home is safe. Passing this inspection gives everyone peace of mind that the foundational work is solid. As part of our process, we coordinate and manage all inspections, so you don’t have to worry about scheduling or paperwork. Once we get the green light, we can move on to insulation and drywall.
Phase 4: Waterproof, Frame, and Drywall
With the new plumbing and electrical systems tucked away, the bathroom starts to take its final shape. This phase is all about building the room’s structure—the walls and ceiling that will eventually hold all your beautiful new finishes. It’s a critical step that requires precision and an eye for detail, because the quality of the work done here directly impacts how well your tile, paint, and fixtures will look and perform. A perfectly flat wall is the only way to get a flawless tile installation, and a properly sealed room is the only way to prevent moisture issues down the line.
This is where we transition from a construction zone to a clean canvas. Our team installs high-performance moisture barriers in all wet areas, hangs specialized backer board for tile, and finishes the drywall to a smooth, seamless surface. We also integrate the ventilation system, which is key to protecting your investment from steam and humidity. While it might seem like a lot of behind-the-scenes work, getting this stage right is non-negotiable for a bathroom remodel that is built to last. It’s the careful, methodical work that ensures your space remains beautiful and functional for years.
Install the Right Moisture Barriers
A beautiful bathroom is a dry bathroom. Before any drywall goes up, we install the right moisture barriers to protect the structure of your home. In areas like the shower and around the tub, we apply a liquid waterproofing membrane that creates a seamless, impenetrable seal. This step is non-negotiable for preventing leaks and mold growth down the road. By creating a watertight environment behind your tile, we ensure your bathroom remodel not only looks great on day one but also stands up to daily use without failing. It’s this attention to the unseen details that makes all the difference in quality and longevity.
Hang and Finish Your Drywall
Once the waterproofing is complete, we can start making the room feel whole again by hanging new drywall. In the shower and other tiled areas, we use a cement backer board, which provides a stable and water-resistant substrate for the tile. For the rest of the walls and ceiling, we install moisture-resistant drywall. Our crews then tape, mud, and sand the seams to create a perfectly smooth surface, ready for primer and paint. This meticulous finishing work ensures there are no visible lines or imperfections, creating a pristine canvas for the final design elements. You can see the flawless results of this prep work in our featured projects.
Install Your Ventilation System
Proper ventilation is your bathroom’s best friend. To protect your new space from moisture, mold, and mildew, we install a high-quality, properly sized exhaust fan. Even if your bathroom has a window, a powerful fan is critical for actively pulling damp air out of the room. We make sure the fan is vented directly to the exterior of your home—never into an attic or crawl space, which can cause serious moisture problems. Integrating this system correctly is a key part of our process and is vital for maintaining healthy air quality and preserving the integrity of your paint, cabinetry, and fixtures.
Phase 5: Install Tile, Fixtures, and Finishes
This is the phase where your new bathroom truly begins to take shape. After all the foundational work behind the walls, you finally get to see your design choices come to life. The tile you picked out in our San Diego showroom, the vanity you fell in love with, and the fixtures that will define the space—it all comes together now. With the drywall up and the room prepped, our skilled crews move from construction to craftsmanship, carefully installing each element with precision. This stage is all about layering finishes correctly to create a beautiful, durable, and functional room. It’s a methodical process that ensures every piece fits perfectly, from the floor up to the lights. Seeing these materials installed is incredibly rewarding, as the textures, colors, and patterns you selected start to build the final picture. Our team takes extra care during this phase to protect all new surfaces, maintaining a clean and organized workspace. This attention to detail ensures that the final reveal is just as exciting as you imagined, without any frustrating setbacks.
Start with the Flooring
The first major finish to go in is the flooring. Whether you’ve chosen elegant porcelain tile or durable luxury vinyl, installing it first creates a clean, continuous surface for everything else to sit on. This approach prevents awkward cuts around vanities or toilets and ensures a more professional, seamless look. Our teams strategically plan the layout, often starting on the wall opposite the door to ensure the most visible tiles are full and perfectly aligned. This careful planning minimizes waste and guarantees the final pattern is balanced and beautiful, setting a solid foundation for the rest of your bathroom remodel.
Install Shower and Wall Tile
Once the floor is set, our attention turns to the walls. This is when your shower gets its waterproof, stylish surround. We install tile from the base of the shower pan upwards, ensuring each line is level and every piece is perfectly placed. If you’ve opted for a tiled accent wall or wainscoting, that goes in now, too. We work carefully to protect your new floor while creating the stunning backdrops that make a bathroom feel custom and complete. Proper installation here is critical not just for looks but for long-term water protection, which is why our expert tile setters are meticulous in their work.
Set the Vanity and Cabinetry
With the tile work complete, it’s time to bring in the furniture. The vanity, along with any linen towers or built-in storage cabinets, is carefully moved into place and secured. Because we planned the electrical layout in an earlier phase, your outlets and sconce wiring will be exactly where they need to be relative to your vanity’s height and mirror placement. Setting the vanity on top of the finished floor ensures a clean installation and makes future replacements much simpler. You can see how these elements come together in our featured projects.
Place Your Toilet, Faucets, and Lighting
This is where the room gets its sparkle. We typically install the toilet last to prevent any accidental chips or scratches while other work is being done. Next, our plumbers install the sink, faucets, and shower trim, making all the final connections. At the same time, our electricians install your vanity lights, overhead fixtures, and exhaust fan. Finally, we hang the mirrors and medicine cabinets, which instantly makes the room feel larger and brighter. Each of these final installations turns the space from a construction zone into a functional, finished bathroom.
Phase 6: Add the Finishing Touches
With the dust settled and the major components in place, this is the phase where your new bathroom truly comes to life. The finishing touches are all about adding the layers of polish and personality that transform a construction zone into a beautiful, functional retreat. All the hard decisions you made during the design phase start to pay off as the final details are installed. This is the last leg of the project, where our team focuses on the meticulous work that ensures every element is perfect before the final walkthrough. From the color on the walls to the handles on your drawers, these last steps are what make the space uniquely yours.
Paint the Walls and Add Trim
Now that the tile, flooring, and vanity are installed, it’s finally time for paint. We wait until this stage to avoid any potential scuffs or damage to fresh paint during the installation of heavier items. For bathrooms, we always recommend a high-quality, moisture-resistant paint, usually in a semi-gloss or satin finish. This not only holds up better against humidity but is also much easier to wipe clean. Once the walls are painted, we install the baseboards and any other trim, like around the door or window. This step creates crisp, clean lines and gives the room a completely finished and cohesive look.
Install Hardware and Accessories
This is where the personality of your new bathroom really shines through. All the beautiful hardware you selected in our Design Center is now carefully installed. This includes cabinet pulls and knobs, towel bars, robe hooks, and the toilet paper holder. We’ll also hang mirrors and mount any medicine cabinets or shelving. While these may seem like small details, they have a huge impact on the room’s style and functionality. Proper placement is key—we make sure everything is level, secure, and positioned exactly where it will be most convenient for your daily routine.
Complete Final Plumbing and Electrical Hookups
The final step is to make everything fully operational. Our licensed electricians and plumbers return to complete the final hookups. This involves installing light fixtures, connecting switches and outlets, and setting the sink faucet and shower trim. We’ll connect the water supply lines, ensure the drain is working perfectly, and test every function to guarantee there are no leaks or issues. This meticulous final check ensures your new bathroom remodel is not only beautiful but also safe, up to code, and ready for you to enjoy for years to come.
Common Sequencing Mistakes to Avoid
Even with the best intentions, a few simple sequencing errors can turn your dream remodel into a logistical headache. Getting the order of operations wrong can lead to damaged materials, costly rework, and frustrating delays that stretch your timeline and budget. The good news is that these pitfalls are entirely avoidable with a solid plan.
Think of your bathroom remodel like a carefully choreographed dance—every step has its place, and timing is everything. When you install a vanity before the floor is finished or start painting before the drywall dust has settled, you create unnecessary problems. A professional team builds a project schedule based on a proven sequence that protects your investment and keeps things moving smoothly. Understanding these common missteps will help you appreciate why a structured approach, like our design-build process, is so critical for a stress-free renovation. Let’s look at a few of the most common sequencing mistakes we see.
Mistake #1: Poor Timing That Causes Delays
One of the fastest ways to derail a bathroom remodel is to start demolition before your materials are on-site and your permits are in hand. It’s tempting to swing a sledgehammer on day one, but this often leads to a gutted, unusable space sitting idle for weeks while you wait for a backordered vanity or a city inspection. Material and permit delays are a leading cause of frustration. A well-managed project involves ordering all your long-lead-time items—like cabinetry, tile, and tubs—well in advance. This ensures everything is ready the moment your crew needs it, preventing momentum-killing pauses in the schedule.
Mistake #2: Installing Fixtures Before Tile
It might seem efficient to get the big pieces in place, but installing your vanity, toilet, or tub before the tile is down is a recipe for disaster. Tiling is a messy job involving mortar, grout, and a lot of cutting. Setting tile around a fixture is not only more difficult and results in a less clean finish, but it also puts your brand-new items at risk of being scratched, chipped, or stained. The correct sequence is to complete the shower and floor tile first. This creates a clean, waterproof surface and protects your beautiful new fixtures from any potential damage during the messiest part of the installation process for your bathroom remodel.
Mistake #3: Skipping Critical Waterproofing
What’s behind your beautiful new tile is arguably the most important part of your entire bathroom remodel. Proper waterproofing is a non-negotiable step that protects your home’s structure from moisture, mold, and rot. Skipping this or using the wrong materials can lead to catastrophic failures down the road. During demolition, it’s also common to uncover pre-existing water damage that needs to be addressed before you can move forward. A reputable contractor will always build time into the schedule for a multi-layered waterproofing system in all wet areas, like the shower walls and floor, ensuring your investment is protected for years to come. You can see the flawless results in our featured projects.
How to Partner with Your Remodeling Contractor
A successful bathroom remodel is more than just a construction project; it’s a partnership between you and your contractor. While your build team handles the technical work, your role is to be an engaged and clear communicator. The best outcomes happen when homeowners and contractors work together toward a shared vision. A firm with a structured process will set the foundation for this collaboration, outlining key milestones and communication touchpoints from the very beginning.
Think of your contractor as your guide. They have the experience to anticipate challenges and map out the most efficient path forward. Your job is to provide the destination—a clear picture of what you want your finished bathroom to look and feel like. When both parties are aligned and communicating openly, you can avoid surprises and ensure the final space is exactly what you dreamed of. This collaborative approach turns a potentially stressful process into an exciting and rewarding one.
Establish Clear Expectations and Timelines
The foundation of a great partnership is set before the first hammer swings. During your initial consultations, be completely open about your goals. Clearly express your expectations for the project, from your design preferences and must-have features to your total budget. Transparency is key. Sharing inspiration photos or a list of priorities helps your contractor understand your vision and create a detailed plan that aligns with it. A professional contractor will, in turn, provide a fixed-bid proposal with a clear scope of work and a predictable timeline, so you know exactly what to expect and when.
Stay Informed About the Process
Once construction begins, consistent communication keeps the project running smoothly. Before work starts, agree on a communication plan with your project manager. Will you have a quick daily text update or a more detailed weekly check-in? Knowing who your main point of contact is and how you’ll receive updates prevents confusion and ensures you always feel in the loop. Working with an in-house team simplifies this, as you have one dedicated point person managing every phase instead of trying to coordinate with separate designers, suppliers, and installers. This streamlined communication is essential for a low-stress remodel.
Have a Plan for Selections and Changes
Making timely decisions on materials is crucial for keeping your project on schedule. To make this easier, gather examples of styles you love before the project starts. Having a clear vision helps your design team guide you toward the right tile, fixtures, and finishes. Visiting a Design Center is one of the best ways to see and touch materials, allowing you to finalize your palette with confidence. This step also helps lock in pricing early, reducing the chance of unexpected costs or changes down the line. When selections are made thoughtfully and upfront, you minimize delays and keep the project moving forward.

Frequently Asked Questions
How long will my bathroom remodel actually take? While every project is different, a full, down-to-the-studs bathroom remodel typically takes several weeks from demolition to the final walkthrough. The timeline depends on the project’s complexity, the lead times for your specific materials, and the inspection schedule. A design-build firm can give you a much more predictable schedule because the design, materials, and construction are all managed by one team, which helps prevent the common delays that happen when juggling separate vendors.
Can I stay in my home during the remodel? Absolutely. Most homeowners live at home throughout the process. A professional remodeling team will take great care to protect your home by sealing off the work area to contain dust and laying down protective coverings on your floors. We also make sure to clean the job site daily. If the project involves your only bathroom, we can help you create a plan to minimize the inconvenience.
What happens if you find unexpected issues like water damage during demolition? It’s fairly common to uncover hidden issues like old leaks, mold, or outdated plumbing once the walls are opened up. This is a normal part of the renovation process and exactly why that discovery phase is so important. When this happens, our project manager will stop, show you exactly what’s going on, and present a clear plan and cost to fix it correctly before any new materials are installed.
Why is it so important to order materials before starting any work? Starting demolition before your vanity, tile, and tub have arrived is one of the biggest causes of project delays. Many items, especially custom or semi-custom pieces, can take weeks or even months to be delivered. Having everything on-site before the work begins ensures a smooth, continuous workflow and prevents your project from stalling while you wait for a critical part to show up.
Do I really need to get a permit for a simple bathroom update? If your remodel involves moving any plumbing, changing the electrical layout, or altering the structure of the room, you will almost certainly need a permit. This isn’t just about following rules; it’s a crucial step that ensures all the work is done safely and meets local building codes, which protects your home’s value. A reputable contractor will manage the entire permitting and inspection process for you.
