CWS Bathroom Remodeling: The San Antonio Owner’s Guide
A full CWS bathroom remodel in San Antonio typically runs $9,000 to $28,000 installed, depending on whether you’re replacing a single fixture or gutting the room to the studs. We handle CWS-compatible bathroom remodeling components from the first tile to the final trim, and most owners call us after living with a failing shower pan, cracked grout, or a vanity that’s quietly warping from San Antonio humidity long enough to stop ignoring it. You’ll know it’s time when the small repair you keep putting off has started affecting the framing, the subfloor, or the drywall behind it.
Here’s the part most people miss: CWS bathroom failures rarely announce themselves loudly. A discolored grout line becomes a slow leak behind the wall. A loose shower handle becomes water inside the valve body. By the time you see the damage, the replacement scope has usually grown. That’s why we price the whole room, not just the visible part.
Key takeaways:
- Full CWS bathroom remodels in San Antonio: $9,000 – $28,000 installed
- Smaller, fixture-level CWS replacements: $3,000 – $12,000 depending on scope
- We provide a written price before work starts, on every CWS bathroom job
- Every crew member is introduced by name and photo before arriving at your door
- Mason Remodeling Co San Antonio is an independent service provider, not affiliated with CWS
Which CWS Models This Applies To
CWS bathroom products span several lines, and the compatibility question is usually about the rough-in dimensions and the valve body, not the finish. We’ve worked on CWS single-handle shower valves, CWS pressure-balanced tub/shower combos, CWS vessel-sink vanities, and CWS low-flow toilet models across San Antonio homes. The model number on most CWS fixtures is stamped on the underside of the tank lid, inside the vanity drawer box, or on the escutcheon plate behind the handle trim.
The compatibility gotcha that catches people: CWS pressure-balanced valves from the mid-2000s use a narrower rough-in spacing than current universal valves. If you buy a replacement cartridge or trim kit without checking the rough-in depth, you’ll be halfway through the job before realizing the new part doesn’t seat. We measure the existing rough-in before ordering anything, and if it’s an older CWS valve body, we’ll tell you whether it makes more sense to swap the whole valve or match the original part. For most San Antonio homes we’re seeing CWS fixtures that are 15 to 25 years old, which puts them right at the point where OEM cartridges are discontinued and a quality aftermarket equivalent is the only practical option. We stock common CWS-compatible cartridges, trim adapters, and drain assemblies on the truck. If we don’t have it, we’ll source it and show you the exact part number and the exact cost before we order.

Signs Your CWS Bathroom Remodeling Is Failing
- Water staining on the ceiling below the bathroom. This usually means the CWS shower pan or the tub drain gasket has been weeping for weeks or months. The leak is almost never where the stain appears; water travels along joists before it drops.
- Grout cracking at the wall-to-floor transition. San Antonio’s clay soil shifts through wet and dry cycles, and that movement shows up first at the change of plane. Cracked grout there means water is working into the substrate.
- A shower handle that turns too far or feels gritty. The CWS pressure-balance cartridge is wearing out. Left alone, it’ll eventually fail to hold temperature, and that’s a scalding risk for kids and older adults.
- Vanity doors swelling or not closing square. High humidity plus a CWS vanity with a poorly sealed bottom edge equals warped doors and a soft cabinet box. Once the box is compromised, replacing the doors alone won’t fix it.
- Mold or mildew returning within days of cleaning. That tells us moisture is trapped behind the tile or under the pan, not on the surface. Surface mold cleans off; sub-surface mold means a rebuild.

AfterReplacement Cost & What’s Included
In San Antonio, a complete CWS bathroom remodel runs $9,000 to $28,000. Here’s how that breaks down:
- Fixture-level CWS replacement (toilet, vanity, shower trim): $3,000 – $8,500
- Tub-to-shower conversion with CWS-compatible valve and tile: $3,500 – $10,000
- Walk-in shower installation with CWS-compatible components: $4,500 – $12,000
- Full bathroom gut and remodel with CWS fixtures: $9,000 – $28,000
What drives the range is the condition of the framing and subfloor once we open the walls. If the CWS pan leaked long enough to rot the joists, that’s structural work on top of the remodel. If the substrate is clean, the number lands lower. Either way, you get a written price before any work begins. Not an estimate. A price. The workmanship is covered by our 365-Day Done Right Promise: if it’s not right within a year of completion, we make it right at no cost. If a repair or installation fails, your return visit is free, no dispute process.
DIY or Call Us?
You can safely check a few things yourself: confirm the CWS model number, look for visible water staining around the base of the toilet and the tub skirt, and run the shower with the trim plate off to see if water is coming from the valve body or the pipe connection. What you should not do is pull a CWS pressure-balance cartridge without shutting the water off and depressurizing the lines, cut into any wall without knowing what’s behind it, or try to level a shower pan that’s already failed. Demolition and re-tiling around a failed CWS shower pan is a multi-day job with waterproofing, slope, and code requirements. If you’re unsure whether the part has failed or the installation did, that’s exactly the kind of call we can make quickly and honestly. Call (254) 269-5071 and we’ll walk you through what you’re seeing and whether it’s a repair or a replacement.
FAQs
A properly installed CWS-compatible bathroom remodel in San Antonio should last 15 to 25 years for the tile and waterproofing, and 10 to 15 years for the fixtures, assuming routine maintenance. The two things that shorten that lifespan here are soil movement affecting grout and pan seals, and humidity accelerating wear on vanities and trim. Call (254) 269-5071 and we’ll tell you what’s realistic for your specific bathroom.
In most cases, no. Once a CWS shower pan leaks, the waterproofing layer has been compromised, and patching a visible crack or reapplying caulk won’t stop water that’s already in the substrate. The right fix is usually a pan replacement with new waterproofing, which we price as part of the overall remodel. Call (254) 269-5071 for a free estimate that covers the actual condition we find.
A fixture-level CWS replacement is typically done in one day. A full bathroom remodel with tile, pan, and waterproofing usually takes five to ten working days depending on scope and what we find behind the walls. We’ll give you the schedule in writing before we start. Call (254) 269-5071 to get a time range for your project.
We carry common CWS-compatible cartridges, trim adapters, drain assemblies, and valve rebuild kits on the truck, and we can source OEM or aftermarket CWS parts for older models in San Antonio within a few days.
