A tub-to-shower conversion in San Diego costs $15,000–$22,000 with California Bathrooms.
We remove your existing tub, build a custom walk-in shower in the same footprint, and install full HydroBlok waterproofing behind every surface. Projects include grout-free wall systems with lifetime warranties and typically complete in 2–4 days. ADA-compliant accessibility features are available at every level.
A Better Use of the Space You Already Have
If you have a tub you have not used in years, there is a good chance it is taking up more space than it is giving back. Stepping over a high tub wall can also become less practical over time, especially if you are thinking about how the bathroom will need to work 5, 10, or 20 years from now.
A tub-to-shower conversion removes the existing bathtub and replaces it with a walk-in shower in the same general footprint. For many San Diego homeowners, it is a straightforward way to improve safety, function, and day-to-day comfort without redesigning the entire bathroom.
California Bathrooms specializes in wet-area remodeling and brings more than 40 years of combined experience to that work. Our approach is built around transparency, long-term value, and California code awareness through our proprietary Crafted to Zero process. The goal is not simply a newer-looking shower. It is a smarter bathroom upgrade built to last.
What Goes Into Our Tub-to-Shower Conversions - and Why It Matters
A tub-to-shower conversion with California Bathrooms starts by removing the existing wet area down to the studs. That gives us access to what actually determines whether the new shower will hold up: framing, substrate conditions, moisture damage, drainage, and waterproofing.
We build the new walk-in shower within the existing tub footprint whenever possible, without unnecessary wall relocation or major plumbing rerouting. We also assess the bathroom’s ventilation to determine whether the existing exhaust fan setup meets current California code requirements or requires an update as part of the conversion.
Every conversion uses HydroBlok waterproofing. HydroBlok is a contractor-only system that requires appropriate licensing and manufacturer training to install. It also carries a lifetime manufacturer warranty on the backing and waterproofing system behind the finished walls.
Wall Systems Available for Your New Shower
Once the waterproofed substrate is in place, we can install the finished wall system. Homeowners can choose between our High-Tech Polymer (HTP) and PuroStone walls.
High-tech polymer walls provide a durable, low-maintenance wall surface across a range of budgets.
PuroStone is the more premium option, with a stone-composite construction and a more substantial look and feel.
Both options are grout-free, eliminating one of the recurring maintenance points in traditional tiled showers. Our HTP vs. PuroStone wall systems guide explains the differences in more detail so you can compare the two before choosing.
Shower Features You Can Build Into the Conversion
A tub-to-shower conversion also gives you the opportunity to add features that improve comfort, organization, accessibility, and day-to-day use. These can be incorporated into the design from the start, so the finished shower works better for its users.
Grab Bars: Provide a secure place to hold when entering, exiting, or moving within the shower.
Built-In Seating: Gives users the option to sit while bathing and can reduce fatigue or balance concerns.
Slip-Resistant Flooring: Adds traction underfoot to help reduce the risk of slips on wet surfaces.
Accessible Control Placement: Positions shower controls where they are easier to reach without excessive bending, stretching, or turning.
Built-In Niches and Shelving: Keep soap, shampoo, and other essentials within easy reach without relying on separate storage accessories.
Glass Doors and Enclosures: Create a more open shower layout while helping contain water within the wet area.
Upgraded Fixtures and Showerheads: Choose fixtures and positioning that better fit your height, mobility, and bathing preferences.
Planning those features during the conversion is usually more practical than trying to add them later. We can reinforce the right areas and place components according to how the shower will actually be used.
For projects focused on mobility or aging in place, our accessible shower remodeling service offers additional ADA-compliant options and safety-focused shower configurations.
Built for Today’s and Tomorrow’s California Building Codes
California bathroom requirements continue to change as the state moves toward broader energy, water, and net-zero goals. Current remodels may need to address elements such as exhaust fans, LED lighting, dimmer controls, and other Title 24 requirements.
Our Crafted to Zero process was developed around that reality. Instead of treating today's inspection requirements as the finish line, we build with upcoming code cycles in mind.
Our in-house installers are trained in this process to stay on top of changing California code requirements. The idea is to understand where bathroom construction is going, not only where the minimum standard sits today.

How Much Does a Tub-to-Shower Conversion in San Diego Cost?
A tub-to-shower conversion in San Diego costs $15,000–$22,000 with California Bathrooms. The exact cost of a conversion depends on what is already in the bathroom and what you choose for the new shower.
We believe you deserve full transparency regarding your investment. To help you understand the factors that influence pricing, our San Diego shower remodel pricing guide breaks down the typical costs for your project.
Financing options are available, including monthly payment plans and qualifying no-interest financing.
Two Layers of Lifetime Warranties
California Bathrooms provides two manufacturer lifetime warranties with qualifying shower systems. One covers the finished materials you see. The other covers the HydroBlok backing and waterproofing system behind them.
Waterproofing is one of the most consequential parts of the shower system, so we believe the protection behind the wall deserves as much attention as the finished surface.
Our guide to lifetime manufacturer warranties vs. lifetime workmanship warranties explains what different types of lifetime coverage actually mean.

Frequently Asked Questions About Tub-to-Shower Conversions
A tub-to-shower conversion costs $15,000–$22,000 with California Bathrooms. This includes tub removal, full waterproofing, walk-in shower build, and lifetime warranty wall systems.
In most cases, yes. We build the new shower in the existing tub footprint, so no major plumbing relocation is needed. We assess feasibility during the free in-home measure.
For most homeowners, yes. A walk-in shower eliminates the step-over required to enter a tub. With barrier-free entry, grab bars, and slip-resistant flooring, it’s a significant safety improvement — especially for aging in place.
In most San Diego homes, a well-built walk-in shower adds more value than an outdated tub — as long as the home still has at least one bathtub elsewhere. If it’s your only bathroom, we’ll discuss options during your consultation.
We tell you what we found and what it means for the project. A tear-down can reveal moisture damage, dry rot, framing problems, or other conditions hidden behind the existing shower or tub. Those findings should be addressed before the new system covers them back up.
A bathroom remodel can trigger current California requirements involving ventilation, lighting, controls, and other components. Crafted to Zero incorporates those requirements into the overall project while also accounting for where upcoming code cycles are headed.
Qualifying systems include two manufacturer lifetime warranties: one covering the finished materials and another covering the HydroBlok backing and waterproofing system. That means warranty protection extends beyond the surface to one of the most important layers behind the walls.
