CWS Bathroom Remodeling: The San Antonio Owner’s Guide
If you have a CWS bathroom and something has failed, you want to know two things right away: what it costs to fix and whether the replacement will fit. For a CWS-compatible bathroom remodel in San Antonio, expect a full replacement to run between $9,000 and $28,000 depending on what failed and how much of the surrounding space needs to come out with it. Most owners discover the problem the way you just did: a valve that stopped holding temperature, a cracked shower base, or trim that corroded faster than it should have in hard Hill Country water.
Graham Stein, owner of Elmstead Remodeling San Antonio, walks every CWS-related job the same way: he writes the scope down before a single tool leaves the truck, and the price you sign is the price you pay. CWS bath components have their own sizing quirks, and swapping them incorrectly means leaks behind tile or a curb that floods the floor. We’re independent of CWS, so our loyalty is to the repair that holds up in a San Antonio bathroom, not to a brand.
Which CWS Models This Applies To

CWS bathroom installations fall into three broad categories we see across San Antonio: pre-2015 acrylic shower pans and surrounds, 2015-and-later modular tub and shower lines, and the wall-hung vanity and lavatory series paired with CWS-supplied valves and trim. The compatibility gotcha is the drain rough-in. Older CWS shower bases were built around a 2-inch drain at a specific offset from the back wall, and if your replacement pan moves that drain even an inch, the plumber is cutting into your slab or crawl space. We measure before we order, every time.
The label matters more than the model name. Look for a CWS sticker or stamp on the underside of the shower base, the back of the valve trim plate, or inside the vanity cabinet door. If the label is gone, we fall back to measurements: the pan width and depth, the drain offset, and the valve inlet spacing. For CWS-specific parts, OEM is the safest path when the part is a shower pan, valve body, or a tub skirt; aftermarket equivalents hold up fine for trim kits, escutcheons, and cartridge stems where the spec is standard. The decision comes down to whether a leak would be cosmetic or structural.
We also stock parts for KraftMaid, Cambria, and Silestone bathroom runs, so if your CWS bathroom shares a cabinet or countertop line from one of those suppliers, we can usually match the finish without special-order lead time.

Signs Your CWS Bathroom Remodeling Is Failing
- A shower valve that won’t hold temperature. The pressure-balancing cartridge inside the CWS valve has worn out, or hard-water scale from San Antonio’s limestone aquifer has seized the slide. If the water goes cold when someone flushes a toilet, the cartridge is the first culprit.
- A soft or flexing shower pan. CWS acrylic pans depend on a mortar bed underneath for support. When the base creaks, flexes, or shows hairline cracks near the drain, the mortar has settled or was never packed correctly at install.
- Grout or caulk pulling away at the tub-to-wall junction. In San Antonio humidity swings, expansion and contraction work the seal loose faster than anywhere dry. Once water gets behind the lip, you’ll see staining at the ceiling below or a musty smell that won’t clear.
- Corroding trim or pitted escutcheons. This is the hallmark of mineral-heavy water eating through the finish. CWS trim from certain production years was more vulnerable; we can match the finish with an aftermarket kit without changing the valve body.
- A vanity cabinet that has swollen at the base or toe kick. CWS bathroom vanities with fiberboard cores don’t survive repeated splashing on the floor line. The cabinet delaminates, doors stop closing square, and the board can’t be sanded back to flat.

AfterReplacement Cost & What’s Included

For a full CWS bathroom remodel in San Antonio, plan on $9,000 to $28,000. A smaller bathroom with a standard tub-to-shower swap or a shower base replacement lands on the low end; a full gut with tile, a CWS vanity replacement, new valve rough-ins, and custom glass pushes the high end.
What changes the number:
- Whether the drain rough-in matches the replacement pan, or needs to be relocated
- Shower glass: framed versus frameless, and whether the original CWS opening is a standard size
- Water damage discovered behind the tile once the old pan or surround comes out
- Tile choice: stock porcelain keeps cost down, large-format or natural stone raises labor and material
- Valve work: if the CWS valve body needs replacing, we open the wall and re-pipe to current code
The written price we hand you covers the part, the labor, the haul-away, drop cloths on the floors, shoe covers at the door, and a photo of the clean-up before the crew leaves. The 365-Day Done Right Promise stands behind the whole job. If it isn’t done right, we make it right.
DIY or Call Us?
You can safely check a few things before calling: read the label on the valve trim or pan, note where the water is pooling or leaking, and shut the water off at the stop valves if you see active spray. That information shortens our first visit. What you should not do is remove a CWS shower pan, cut into the wall behind the valve, or pull the valve cartridge without shutting down the whole house supply first. A pan that’s been siliconed down wrong will leak under the tile, and a cartridge yanked under pressure can crack the valve body inside the wall. That turns a $400 cartridge fix into a wall-open, re-pipe job.
We’d rather talk to you before anything comes apart. Call (432) 233-0976 and describe what you’re seeing. We’ll tell you over the phone whether it sounds like a CWS trim issue or a base failure, and schedule a walkthrough at a time that works around nap schedules and school runs.
FAQs

A properly installed CWS bathroom in San Antonio should give you 15 to 25 years before the pan, valve, or vanity shows real failure. Hard water shortens the trim finish life to about half that, especially if the original trim was a lower-grade finish. Regular re-caulking is the single best thing you can do to extend the life of any acrylic surround or tub.
Call (432) 233-0976 for an honest read on whether your bathroom has years left or is near the end of its service life. Estimates are free.
Some CWS failures are repairable: a worn pressure-balancing cartridge, a failed diverter stem, or loose trim can be swapped without opening the wall. A cracked pan, a delaminated vanity, or a corroded valve body is a replacement job, because the material itself has died. We won’t patch something that will fail again in a year just to make a quick sale.
If you’re not sure which category your failure falls into, call (432) 233-0976. A phone call gets you a straight answer, not a sales pitch.
Most CWS bathroom remodels in San Antonio run five to ten working days depending on tile, glass, and whether water damage needs remediation. A straightforward shower base and valve replacement can be done in two to three days. We protect clean floors and quiet hours while we’re there, and the written scope comes with a timeline before we start.
Call (432) 233-0976 for a timetable specific to your bathroom’s condition and your product choices.
Our San Antonio crews carry common CWS-compatible cartridges, trim kits, and pan gaskets on the truck for the 2015-and-later modular lines, so a first visit often ends with the part installed. Pre-2015 CWS pans and valve bodies are usually ordered to match your measurements, with a lead time of three to seven business days. We confirm the exact part before we order, so you’re never paying for the wrong size.
Call (432) 233-0976 with your label info and we’ll check stock and lead times for your exact CWS part.
We keep the process simple: write it down, price it once, do it right. When the written quote is on the table and the scope is clear, the remodeling decision gets a lot easier. Call (432) 233-0976 to schedule your free estimate, and we’ll walk your San Antonio bathroom room by room, just like Graham does on every job he bids.
