CWS Bathroom Remodeling: The Austin Owner’s Guide
If you have a CWS bathroom and something’s failing, you’re not looking for a sales pitch. You’re looking for someone who knows the product, can match the part, and will tell you what the fix costs before anyone touches a wrench. At Penhallow Remodeling Austin, we install and service CWS-compatible bathroom remodeling components, with full bathroom remodels in Austin typically running $9,000 to $28,000 depending on scope. Most CWS owners reach out after weeks of ignoring a slow drain, a soft spot in the vanity, or grout that’s been crumbling for longer than we’d wait to mention it.
We’re an independent Austin remodeling contractor. We’re not affiliated with CWS, but we’ve worked on enough CWS bathrooms across the city to know exactly what fails, why it fails, and what retrofits actually hold up in central Texas heat and humidity.
Which CWS Models This Applies To
CWS bathroom layouts vary by whether you’re talking about a pre-fabricated shower pan system, a modular vanity base, or a wet-wall configuration. The compatibility question usually comes down to the rough-in dimensions behind the wall and under the floor, not the visible finish. Older CWS shower assemblies in Austin homes, particularly in neighborhoods like Rosedale, Brentwood, and Crestview, tend to use a 30-by-60-inch pan with a 2-inch center drain. Some later runs use a 32-by-60-inch pan, and it’s easy to assume the smaller one will fit. It won’t, not without reworking the subfloor and wall board, and that changes the price.
If you’re trying to identify your CWS model, pull the escutcheon plate behind the shower handle and look for the stamped date code on the valve body. We also measure the trim ring spacing on the hot and cold inlets, because CWS used 8-inch centers on some lines and standard 6-inch centers on others. For replacement components, genuine CWS parts exist but have become harder to source in the Austin market, and lead times on ordered trim sometimes stretch past six weeks. Quality aftermarket equivalents from recognized trade brands like Kohler, Moen, and Delta fit most CWS rough-ins with minimal adaptation, and they carry their own manufacturer warranties alongside our 365-day workmanship promise.

Signs Your CWS Bathroom Remodeling Is Failing
- Silicone sealant pulling away at the pan-to-wall joint. This is the early warning that water has been sitting where it shouldn’t. Once the silicone lifts, capillary action draws moisture into the substrate (the moisture-resistant layer behind your tile), and rot begins quietly.
- Tile movement or hollow-sounding spots in the bottom two rows. That’s a sign the tile has delaminated from the substrate. In Austin bathrooms built on slab floors, we often find this in showers where the pan weep holes were never cleaned.
- A persistent sour or musty smell that cleaning doesn’t touch. That’s embedded moisture in the drywall or fiberboard behind a CWS modular wall system. Mold doesn’t care how much bleach you pour on the surface.
- Vanity base swelling along the toe-kick or corners. CWS vanities used particleboard cores under a laminate face in some production years. Once moisture from bathroom humidity or occasional overflow gets into that core, the material loses its structural integrity and the doors stop aligning.
- Shower valve pressure drops when another fixture turns on. This points to cartridge or diverter wear inside the CWS valve. It’s a repairable part, not a full remodel, if we catch it before scale and mineral buildup from Austin’s hard water etch the valve body.

AfterReplacement Cost & What’s Included
A full CWS bathroom remodel in Austin runs $9,000 to $28,000. That range accounts for whether you’re replacing the shower assembly and vanity only, or gutting the room to studs, redoing the waterproofing, moving plumbing, and rebuilding the layout. A small CWS bathroom, like a second-floor hall bath in an older Lakeway home, lands between $5,000 and $12,000 when we’re not relocating any fixtures.
| Scope | Typical Austin Installed Price |
|---|---|
| Shower replacement only (pan, wall system, valve) | $3,000 – $8,500 |
| Tub-to-shower conversion | $3,500 – $10,000 |
| Walk-in shower installation | $4,500 – $12,000 |
| Vanity installation | $800 – $3,000 |
| Full CWS bathroom remodel | $9,000 – $28,000 |
Every price includes the same thing: a written number before any work starts, background-checked technicians in uniform, and the 365-Day Done Right Promise. If the work fails inside the guarantee period, we come back and fix it. No charge, no re-inspection fee, no phone tree.
DIY or Call Us?
You can check a few things safely: the condition of caulk lines, whether the escutcheon is snug, whether the drain cover moves when you press on it, whether you can see your CWS model stamp. What you shouldn’t do is pull the valve cartridge or open the wall. Wet-wall systems in CWS bathrooms run hot and cold supply lines under pressure, and one wrong twist behind a valve can turn a small repair into a flood while you’re at work.
We also see DIYers sand down a swollen vanity core, paint over it, and hope it holds. It doesn’t. Swollen particleboard doesn’t recover. If you’re not sure what you’re looking at, call us at (325) 225-5429 and describe the symptom. Tell me what you need, I’ll tell you what it costs, and we’ll go from there.
FAQs
With proper waterproofing and hard-water-resistant fixtures, we expect a full CWS bathroom remodel in Austin to last 15 to 25 years before major systems need attention. Shower caulk and valve cartridges are wear items and will need service sooner, usually at 3 to 5 years and 7 to 10 years respectively.
Yes, if the damage is confined to the valve, trim, or sealant and the substrate behind the tile hasn’t wicked moisture. We’ll do a written assessment and tell you honestly if a repair buys you real years or just delays a bigger job. Call (325) 225-5429 for a free estimate either way.
A shower-only replacement typically takes 2 to 4 working days in Austin. A full CWS bathroom remodel runs 2 to 4 weeks depending on plumbing relocations, permitting, and material lead times. We give you a defined arrival window in writing before we start, along with the price.
We carry common CWS-compatible cartridges, escutcheon adapters, drain assemblies, and pan-to-wall transition kits on our service trucks across Austin. For full wall systems or vanities, we source and order to your project, then install in one scheduled visit. We also stock and install parts for KraftMaid, Cambria, and Silestone products when a remodel crosses into the vanity or countertop.
