A tub-to-shower conversion involves much more than just swapping out a fixture. It’s a project that requires expert plumbing, precise tile work, and, most importantly, flawless waterproofing to protect your home. The quality of what’s behind the walls is even more critical than the beautiful tile you see on the surface. That’s why hiring a specialist is non-negotiable. We’ll walk you through the essential credentials, installation methods, and red flags to watch for. This guide will help you confidently vet the best tub to shower conversion companies and find a team that gets the job done right.
Key Takeaways
- Choose Your Remodel Type: Decide if you want a quick, functional update using a pre-fabricated system from a national chain, or a fully custom, tiled shower from a local design-build firm that offers complete design freedom and addresses underlying issues.
- Vet Your Contractor Thoroughly: Before signing anything, verify the company’s state license and insurance, read recent client reviews, and insist on a detailed, itemized proposal that outlines the full scope of work and protects you from surprise costs.
- Look Beyond the Lowest Bid: A price that seems too good to be true often means cutting corners on essential steps like waterproofing. Investing in a specialist ensures the job is done right from the studs out, preventing costly leaks and future repairs.
A Homeowner’s Guide to the Best Tub-to-Shower Conversion Companies
Swapping an old, bulky bathtub for a sleek, modern walk-in shower is one of the most popular bathroom upgrades—and for good reason. It can make your space feel larger, improve accessibility, and update the entire look of the room. But choosing the right company to bring your vision to life is just as important as picking out the tile. The market is filled with options, from national chains specializing in quick installations to local design-build firms offering fully custom solutions.
Companies like Re-Bath and Bath Fitter are known for their fast turnarounds, often completing a conversion in just a few days using pre-fabricated systems and acrylic liners. This approach is great if you need a simple, functional update with minimal disruption. Similarly, Jacuzzi Bath Remodel focuses on sleek, modern systems that replace your old tub without the mess of a lengthy demolition. These specialists are a solid choice for a straightforward swap.
However, if your project involves more than just replacing the fixture, you might need a more comprehensive approach. A full bathroom remodeling expert handles everything from custom tile and frameless glass doors to moving plumbing and updating lighting. This is where a design-build firm shines, managing the entire process from the initial design to the final walkthrough. They also handle the critical details that are easy to overlook, like securing permits and ensuring the new shower floor has the perfect slope to drain properly—one of several common conversion mistakes that can cause major headaches later. Understanding the difference between a quick-install specialist and a full-service remodeler is the first step in finding the right partner for your project.
What Defines a Great Tub-to-Shower Conversion Company?
Choosing the right company for your tub-to-shower conversion is the single most important decision you’ll make for your project. This isn’t just about swapping out a fixture; it’s a project that involves plumbing, waterproofing, demolition, and detailed tile work. The right partner makes the process feel seamless and exciting, while the wrong one can lead to delays, budget surprises, and long-term issues like leaks.
So, what separates the best from the rest? It comes down to a few key pillars: specialized expertise, proper credentials, access to quality materials, transparent business practices, and a solid commitment to their work. A great company doesn’t just sell you a product; they guide you through a proven remodeling process, from initial design to final walkthrough. They listen to your needs, respect your home, and have the portfolio and reviews to back up their promises. Before you sign any contracts, make sure the company you’re considering checks all the boxes below.
Specialized Experience in Bathroom Remodels
You wouldn’t ask a general family doctor to perform heart surgery, and the same logic applies here. While many general contractors can do the job, a company that specializes in bathroom remodeling brings a much deeper level of expertise. They live and breathe this work every day. They understand the specific challenges of wet environments, from ensuring proper slope for drainage to installing flawless waterproofing systems that protect your home for years to come. Look for a contractor with a rich portfolio of completed tub-to-shower conversions. Their experience not only impacts the quality of the final product but also the efficiency of the entire project.
Proper Licensing and Insurance
This is a non-negotiable. Any contractor working in your home must be properly licensed, bonded, and insured. In California, you can and should verify a contractor’s license with the Contractors State License Board (CSLB). A valid license means they’ve met state requirements for competency, while insurance protects you from liability if a worker is injured on your property. Bonding offers financial protection if the contractor fails to complete the job or pay for materials. A reputable company will readily provide you with their license number and proof of insurance—if they hesitate, that’s a major red flag.
Quality Materials and Custom Design Options
The best companies offer more than just a pre-fabricated shower kit. They provide a guided design experience with a wide selection of quality materials. Your new shower should not only be functional but also reflect your personal style. A company with a dedicated design showroom is a huge advantage, as it allows you to see and touch tile, stone, and fixtures in person. This helps you make confident decisions and visualize the final result. Strong materials and thoughtful craftsmanship ensure your new shower doesn’t just look great on day one but stands the test of time.
Transparent, Detailed Estimates
A vague, one-line quote is a recipe for disaster. A professional and trustworthy company will provide a detailed, itemized estimate that clearly outlines the full scope of work. This document should break down the costs for labor, materials, permits, and any other associated fees. It’s wise to get at least three quotes to compare, but don’t just look at the bottom line. A transparent proposal helps you understand exactly what you’re paying for and protects you from unexpected costs down the road. This level of detail is a sign of a contractor who is organized, honest, and respects your budget.
A Strong Warranty and Post-Project Support
A company’s commitment to you shouldn’t end the day they pack up their tools. A strong warranty that covers both materials and workmanship is essential for your peace of mind. Ask potential contractors what their warranty includes and how long it lasts. A company that stands behind its work will have a clear process for addressing any issues that may arise after the project is complete. This post-project support is just as important as the installation itself, as it shows the company is dedicated to your long-term satisfaction and confident in the quality of their work.
Comparing the Top Tub-to-Shower Conversion Companies
Choosing the right company for your tub-to-shower conversion can feel like a big decision, because it is. You’re not just buying a product; you’re inviting a team into your home to make a significant change to your daily routine. The market is filled with options, from national chains that promise one-day installations to local design-build firms that offer fully custom solutions. Each has its own approach, and the best fit for you really depends on your goals.
Are you looking for a quick, functional update with minimal disruption? Or do you envision a complete transformation that rethinks the entire space? To help you sort through your options, we’ve broken down some of the most well-known companies in the business, including national brands and local San Diego experts. We’ll look at what makes each one unique so you can find a partner that aligns with your vision, budget, and timeline.
King Remodeling (San Diego’s Design-Build Experts)
If you’re looking for a truly custom shower that’s designed specifically for your home, a local design-build firm like King Remodeling is your best bet. Unlike national chains that often rely on pre-fabricated acrylic liners and wall systems, we take a comprehensive approach. Our process involves completely removing the old tub and redesigning the space from the studs out. This allows for total creative freedom—from beautiful, hand-laid tile and custom glass enclosures to relocating plumbing for a more functional layout. As a full-service bathroom remodeling team, we handle everything in-house, from the initial design concepts to material selection in our private showroom and the final build, ensuring a seamless experience with a single point of contact.
Re-Bath
Re-Bath is a national franchise that specializes in fast and efficient bathroom updates. Their main selling point is a streamlined process that can transform your tub into a new walk-in shower in just a few days. They use their own line of proprietary materials, like DuraBath™, a non-porous acrylic that is designed to be waterproof and resistant to mold and mildew, making it a low-maintenance option. Re-Bath’s services also include options that meet ADA standards, making them a solid choice for homeowners who are focused on safety, accessibility, and a quick turnaround without the complexity of a full-scale remodel.
Bath Fitter
Bath Fitter is well-known for its unique installation method: a custom-molded acrylic shower liner that fits directly over your existing bathtub and walls. This approach minimizes demolition, which means less mess, less dust, and a much faster installation—often completed in as little as one day. Because there’s no need to tear out the old tub, it’s a less invasive process. Bath Fitter’s tub-to-shower conversions are particularly popular with homeowners who prioritize speed and convenience. They also offer a range of built-in safety features like grab bars and seating, making them a practical choice for anyone looking to improve bathroom accessibility quickly.
Jacuzzi Bath Remodel
Leveraging a brand name synonymous with luxury, Jacuzzi Bath Remodel offers stylish tub-to-shower conversions that can often be completed in as little as one day. Their focus is on combining a high-end aesthetic with practical features. You can customize your new shower with a wide selection of textures, colors, and accessories, including various shower heads, shelving, and safety features like grab bars and movable seats. For homeowners who want the assurance of a well-known brand and a modern, sleek look without committing to a lengthy renovation, Jacuzzi Bath Remodel provides a compelling and convenient option.
Home Depot Bath Services
As one of the largest home improvement retailers, Home Depot offers tub-to-shower conversions through its network of local, authorized service providers. This is a convenient option if you prefer to work with a familiar national brand that manages the project for you. The process typically starts with an in-home or virtual consultation to discuss your needs and measure your space. While the products and materials come from Home Depot’s extensive inventory, the installation is handled by a certified local contractor. Customer reviews often highlight the speed and cleanliness of the installation, making it a reliable choice for a straightforward conversion.
Lowe’s Bath Solutions
Similar to Home Depot, Lowe’s connects homeowners with a network of independent, professional installers to handle tub-to-shower conversions. Their process begins with a project specialist who helps you select products and design the space, ensuring the final result meets your expectations. Lowe’s offers a wide variety of shower systems, doors, and fixtures from multiple brands, giving you plenty of choices. By managing the project and backing the installation with a one-year labor guarantee, Lowe’s provides a structured process for homeowners who want the product selection of a big-box store combined with the assurance of a professionally managed installation.
Installation and Timelines: What to Expect
The installation phase is where your vision for a new shower finally takes shape. But how long it takes and what the process looks like can differ dramatically from one company to the next. While some national brands promise lightning-fast turnarounds, a custom remodel focuses on precision, quality, and addressing the unique needs of your space. Understanding the difference is key to setting the right expectations for your project.
A one-day installation often involves placing a pre-fabricated liner over your existing tub and walls, which limits design choices and may not address underlying issues like old plumbing or hidden water damage. A full, custom tub-to-shower conversion is a more involved process that includes complete demolition, plumbing updates, and meticulous tile work. While it takes longer, this approach gives you total design freedom and the peace of mind that comes from knowing the job was done right from the studs out. A professional team will protect your home, manage dust, and keep you informed every step of the way, ensuring the final result is as durable as it is beautiful.
One-Day Installs vs. Custom Remodels
The promise of a one-day installation is tempting, and for some homeowners, it’s the right fit. Companies like Bath Fitter and Jacuzzi Bath Remodel specialize in this approach, often using acrylic liners and wall systems that can be installed quickly with minimal disruption. This method is great for a fast, functional update without changing the bathroom’s footprint.
However, a full custom bathroom remodel offers a completely different level of quality and personalization. This process involves removing the old tub and surround down to the studs, allowing your contractor to inspect for damage, update plumbing, and build a truly waterproof, custom-tiled shower. It’s a more comprehensive solution that gives you endless design possibilities—from built-in niches and benches to frameless glass doors—and adds significant long-term value to your home.
The Importance of Proper Waterproofing
What’s behind your shower walls is even more important than the tile you see on the surface. Proper waterproofing is the single most critical factor in ensuring your new shower lasts for decades without leaks, mold, or rot. A professional installation involves multiple layers of protection, from a sloped mortar bed and waterproof membrane to sealed seams and backer board.
Cutting corners here can be disastrous. As experts note, fixing an improperly waterproofed shower is incredibly costly and often requires a full tear-out and remodel. Furthermore, many municipalities require permits for shower conversions, especially when plumbing is moved. A reputable contractor with a transparent remodeling process will handle all necessary permits and inspections, ensuring your project is built to code and will stand the test of time.
How Demolition and Prep Work Should Be Handled
A successful remodel begins with careful and precise preparation. Professional demolition isn’t about brute force; it’s about systematically removing the old fixtures while protecting the rest of your bathroom and home. Once the space is open, your team should confirm that the area is structurally sound and ready for the new installation.
This is also the stage where accuracy is paramount. Your contractor must take precise measurements to ensure the new shower base fits perfectly and drains correctly. Any deviation can cause misalignment and pooling water. They should also evaluate your bathroom’s ventilation to ensure it can handle the moisture from a new shower, preventing future mold and mildew growth. The beautiful results you see in project galleries always start with this kind of meticulous, behind-the-scenes prep work.
How Much Does a Tub-to-Shower Conversion Cost?
Talking about the budget is one of the most important parts of any remodel. While it’s tempting to look for a simple price tag, the truth is that the cost of a tub-to-shower conversion varies widely. The final price depends entirely on the scope of your project, the materials you choose, and the existing condition of your bathroom.
A simple, pre-fabricated insert will cost less than a custom-tiled shower with a frameless glass door and a rain shower head. That’s why the best companies won’t give you a quote over the phone. Instead, they’ll provide a detailed, in-person consultation to understand your vision and assess your space. This approach ensures you get a firm, accurate price based on your specific needs, not a vague estimate that’s likely to change. The goal is to get a fixed-price proposal that covers everything from demolition to the final fixture, giving you confidence in your investment.
Understanding the Average Cost
Because every project is unique, the “average cost” can be misleading. The final price of your bathroom remodel is shaped by several key factors. These include the size of your new shower, the type of materials you select (like porcelain tile versus a solid surface panel), and the complexity of the plumbing or electrical work required. Moving a drain or adding recessed lighting, for example, will impact the total cost.
The best way to get an accurate number is to schedule a free consultation. An experienced professional can assess your space, discuss your goals, and provide a detailed quote that breaks down every expense. While some companies advertise quick, one-day installations, a truly custom conversion takes time to ensure quality. High-end products often come with a strong warranty, like a Limited Lifetime Warranty, which reflects the company’s confidence in their materials and craftsmanship.
Common Financing and Payment Options
A bathroom remodel is a significant investment, but many companies offer financing to make it more manageable. You’ll often find flexible payment plans designed to fit different budgets, which can be a great way to get the shower you want without paying the full amount upfront. Some national brands even promote offers like no interest and no payments for up to a year, though this usually depends on credit approval and specific terms.
Whether you’re considering financing or paying outright, the most important thing is financial clarity. A trustworthy contractor will provide a transparent, fixed-price contract that details every cost before work begins. Understanding the payment schedule and the total investment is a core part of our process, as it prevents surprises and ensures you feel comfortable from start to finish. Always read the fine print on any financing agreement to fully understand the terms.
Potential Hidden Costs to Look Out For
Nothing sours a remodeling project faster than unexpected costs. While a good contractor will anticipate most issues, there are a few common surprises to be aware of. Many cities, including those in San Diego County, require permits for projects involving plumbing or electrical changes, so make sure that cost is included in your estimate.
Once the old tub is removed, it’s possible to uncover hidden water damage, mold, or a rotted subfloor that must be repaired before the new shower can be installed. Neglecting proper drain positioning or failing to waterproof correctly can also lead to major expenses down the road. A thorough contractor will inspect for these issues from the start and build contingencies into the plan. Working with an experienced design-build team helps minimize these risks, as they manage the entire project and provide a comprehensive scope of work that accounts for potential challenges.
Common Mistakes to Avoid When Choosing a Company
Selecting the right company for your tub-to-shower conversion is just as critical as picking out the perfect tile. The team you hire will be in your home for days or weeks, and their skill determines the final quality and longevity of your new bathroom. A great partner makes the process feel seamless and exciting, while the wrong one can turn your dream project into a source of stress.
Unfortunately, it’s easy to get sidetracked by a flashy sales pitch or a surprisingly low price. To make sure you find a team that delivers on its promises, it helps to know what pitfalls to look out for. From verifying credentials to demanding a detailed plan, doing your homework upfront protects your investment and ensures you end up with a shower you love for years to come. Let’s walk through the most common missteps homeowners make and how you can steer clear of them.
Choosing a Contractor Based on Price Alone
It’s tempting to jump on the lowest bid, but a price that seems too good to be true usually is. Bargain contractors often cut corners by using subpar materials, hiring inexperienced labor, or skipping essential steps like proper waterproofing. While you might save money initially, these shortcuts can lead to costly leaks, cracked tiles, and mold issues down the road. Think of your remodel as an investment in your home’s value and your daily comfort. A reputable company provides a detailed, fixed-price proposal that reflects quality materials, skilled craftsmanship, and a comprehensive design-build process that delivers lasting value.
Forgetting to Check Reviews and Credentials
Before you sign any contracts, do a little digging. The first step is to verify that the company has a valid contractor’s license and carries both liability insurance and workers’ compensation. This protects you from any accidents on your property. Next, check online reviews on sites like Google and Yelp to see what past clients have to say. Many cities also require permits for bathroom remodeling, especially when plumbing is moved, so you need a contractor who knows and follows local building codes. A trustworthy company will be proud to share its credentials and show you a portfolio of its completed projects.
Ignoring the Value of Specialized Experience
A tub-to-shower conversion isn’t a job for a general handyman. It requires specific expertise in plumbing, tile setting, and especially waterproofing. An improperly sealed shower is a nightmare waiting to happen. As experts note, “fixing improperly waterproofed showers is quite costly and often requires a full bathroom remodel.” A team that specializes in bathrooms understands the unique challenges of working in wet environments. They know how to properly slope a shower floor for drainage, install a leak-proof shower pan, and ensure every seam is perfectly sealed. Hiring a specialist gives you peace of mind that the job is done right the first time.
Accepting a Vague or Incomplete Estimate
A one-line quote on the back of a business card is a major red flag. A professional and transparent estimate should be a detailed document that breaks down every aspect of the project. It should clearly outline the scope of work, material costs, labor charges, permit fees, and a projected timeline. A vague proposal leaves room for surprise charges and misunderstandings. A detailed plan shows that the contractor has thought through every step, from demolition and drain placement to ventilation and fixture installation. Don’t be afraid to ask for a comprehensive quote that leaves no room for doubt.
How to Make Your Final Decision
You’ve done the research, gathered inspiration, and are ready to choose a partner for your tub-to-shower conversion. This final step is all about asking the right questions and trusting your gut. A successful remodel depends on finding a team that combines technical skill with clear communication and a process you can count on. Here’s how to confidently make your choice and move forward with a contractor who will bring your vision to life.
Local Experts vs. National Chains: Which is Right for You?
When you’re deciding between a big-box store and a local specialist, think about the kind of experience you want. National chains can offer standardized packages, but a local design-build firm provides a level of personalized service that’s hard to match. San Diego contractors understand our region’s specific building codes, architectural styles, and even the climate’s impact on materials. A local team is invested in the community and builds its reputation on happy clients, not just high volume. This often translates to more flexibility in design, better communication, and a deeper commitment to getting every detail right for your home.
Red Flags That Signal a Bad Contractor
Knowing what to watch out for is just as important as knowing what to look for. Be cautious of any contractor who gives you a quote over the phone without seeing the space or who seems hesitant to provide a detailed, written estimate. A major red flag is a failure to take precise measurements of your existing tub and bathroom—any deviation can cause serious alignment and waterproofing issues down the road. Also, be wary of anyone who dismisses the need for permits. Many tub-to-shower conversions require them, and a professional will always follow the proper procedures to ensure your project is safe and compliant. A transparent remodeling process should be clear from the start.
The Most Important Questions to Ask Before You Hire
Before you sign a contract, make sure you have clear answers to a few key questions. Start with the basics: Are you licensed and insured in California? Who will be the main point of contact for my project? Then, get into the specifics of their process. Ask them to evaluate your bathroom space and explain how they’ll ensure the new shower fits comfortably and functionally. Inquire about their team—are the designers, plumbers, and installers in-house employees or subcontractors? Finally, ask how material selection works. A company with a dedicated design showroom can make choosing tile, fixtures, and finishes a seamless and enjoyable part of the experience.

Frequently Asked Questions
How long does a tub-to-shower conversion actually take? While some companies advertise one-day installations, a high-quality, custom conversion typically takes longer. A quick install often involves placing a pre-made liner over your existing walls, which is fast but limits your design choices. A full remodel involves removing the old tub down to the studs, updating plumbing, installing a proper waterproof system, and meticulously setting tile. This more thorough process can take one to two weeks but ensures the job is done right and gives you a truly custom result that lasts.
What’s the real difference between a quick-install liner and a custom-tiled shower? The main difference comes down to customization and long-term durability. An acrylic liner is a pre-fabricated system that fits over your existing space, offering a fast and functional update with limited design options. A custom-tiled shower is built from scratch, giving you complete freedom to choose the size, layout, tile, and features like niches or benches. More importantly, a custom build allows your contractor to install a robust, multi-layered waterproofing system directly on the studs, which is the best defense against future leaks and water damage.
Will I have to hire my own plumber or other tradespeople? That depends on the type of company you choose. If you hire a general contractor or manage the project yourself, you may need to coordinate with separate plumbers, tile setters, and electricians. However, a design-build firm manages the entire project with one team. This means they handle all the scheduling and coordination of their in-house or vetted trade partners, giving you a single point of contact and a much smoother, more predictable remodeling experience.
What happens if you find unexpected problems like mold after you remove the old tub? This is a common concern, and it’s exactly why working with an experienced remodeler is so important. A professional team will assess the situation immediately and explain the problem and the solution clearly. Any necessary repairs, like replacing a rotted subfloor or treating mold, would be addressed before any new work begins. A transparent contractor will have a clear process for handling these changes, ensuring you approve any additional work and costs before they move forward.
Why is a detailed, in-person quote so important? A vague quote is a recipe for surprise costs later on. A trustworthy contractor will insist on seeing your space in person before giving you a price. This allows them to take precise measurements, assess your plumbing, and understand your vision. The detailed, itemized proposal they provide should break down all costs for labor, materials, and permits. This document protects you by creating a clear scope of work and ensures the price you agree to is the price you pay.
