CWS Bathroom Remodeling: The Miami Owner’s Guide
CWS bathroom remodeling in Miami typically runs $10,620-$33,040 for a full replacement, with most projects quoted within 24 hours and started within two weeks of approval. We stock CWS-compatible fixtures, hardware, and finishing kits, and we carry KraftMaid, Cambria, and Silestone lines as alternatives when a closer match to your existing layout makes more sense. Most Miami homeowners realize something’s wrong when grout cracks spread after a humid summer, or when the vanity cabinet starts swelling at the toe kick because the original moisture barrier was cut short.
Which CWS Models This Applies To
CWS bathroom systems are identified by a model stamp inside the cabinet door or on the vanity base rail, usually a four-digit code starting with 19 or 24 for the pre-2018 residential line, and 30-series for the post-2018 frameless collections. The critical compatibility point is the rough-in depth: CWS used 18-inch vanities in the 1900 series but switched to 21-inch in the 2400 and 3000 lines, and forcing the wrong depth against a Miami-Dade block wall leaves no room for the P-trap swing.
We source OEM CWS hardware through three regional distributors, but for countertops we often quote Cambria or Silestone equivalents that match the original quartz spec at a tighter price. The 3000-series soft-close hinges are proprietary; the 1900/2400 hinges are standard Blum mounts you can match at most Miami supply houses. We measure twice, write it down, then build it - the quote specifies which route we’re taking before you sign.
Signs Your CWS Bathroom Remodeling Is Failing

- Swelling at the cabinet toe kick or side panels. CWS used a vinyl-coated particle board in the 1900 series that delaminates when Miami’s humidity pushes past 75 percent for extended stretches. The fix is a full cabinet replacement with marine-grade plywood, not a surface patch.
- Grout cracking in the shower surround, especially at the bench or curb. This usually means the waterproofing membrane failed at a seam or the preslope was omitted during original construction. Water is getting behind the tile and into the wall cavity.
- Fixture finish flaking or turning green at the edges. CWS chrome from the 2015-2019 period had a thinner nickel undercoat that corrodes fast in South Florida’s salt air. We see this most in Coral Gables and Key Biscayne installs within six miles of the bay.
- Vanity top separating from the cabinet body. The original silicone bead breaks down, but the real problem is often that the cabinet wasn’t shimmed level and the weight is now torquing the frame. Re-setting the top without fixing the frame buys you two years, maybe three.
- Soft spots in the floor near the toilet or tub. This is subfloor damage from a slow leak, and it means the remodel scope just expanded. We document it with photos before we touch anything so you know exactly what changed and why.

| Scope | Price Range in Miami |
|---|---|
| Full bathroom remodel (CWS or compatible) | $10,620 - $33,040 |
| Small bathroom remodel | $5,900 - $14,160 |
| Walk-in shower installation | $5,310 - $14,160 |
| Tub-to-shower conversion | $4,130 - $11,800 |
| Shower replacement only | $3,540 - $10,030 |
| Bathroom vanity installation | $945 - $3,540 |
The range depends on three things: whether we’re working with existing plumbing locations, what the wall and floor substrate condition is once we open it, and whether you want to stay in the CWS ecosystem or switch to KraftMaid cabinetry with a Cambria top. Every quote is a flat written price with a written scope, and no work proceeds on a change until the change order is signed. Under Clause 1 of the Haven Standard, that price is locked before anyone picks up a tool.
DIY or Call Us?

There’s a short list of checks any homeowner can do safely. Verify the model number on the cabinet stamp. Look for the water shutoff valves and confirm they turn - in Miami’s older buildings, especially in Coconut Grove and parts of Little Havana, the original brass valves seize after fifteen years. Take photos of the existing layout from multiple angles; you’ll need them for any contractor’s quote.
What goes wrong fast: removing a vanity without supporting the existing plumbing can crack a solder joint inside the wall. Demoing tile without verifying whether it’s a mud bed or cement board substrate changes the disposal cost by hundreds of dollars and the labor by days. And any work behind the walls - membrane replacement, subfloor repair, vent stack modification - requires a Miami-Dade permit and a licensed plumber. We’re licensed and insured, we pull the permits, and we pass the inspections. Call (786) 321-4970 to schedule your free estimate.
FAQs
A properly installed bathroom with marine-grade materials and a complete waterproofing system should last 20-25 years in Miami’s climate, though the 1900-series CWS cabinets we see in homes built 2010-2016 are often failing at 8-12 years due to the particle board core. The difference is usually the substrate and the quality of the initial membrane installation. Call (786) 321-4970 for an exact quote - estimates are free.
Surface repairs - new hinges, a re-glued drawer box, a replacement countertop - are practical if the cabinet carcass is still square and dry. Once the particle board swells or the laminate peels, repair costs approach replacement without solving the underlying moisture problem. We document the condition with photos and give you both numbers in writing. Call (786) 321-4970 for an exact quote - estimates are free.
Most full replacements run 10-14 working days from demo to final walkthrough, assuming standard Miami-Dade permitting timelines and no hidden subfloor damage. A tub-to-shower conversion or vanity-only swap can finish in 3-5 days. We provide a written schedule with the quote, and we update it if the permit inspection slips. Call (786) 321-4970 for an exact quote - estimates are free.
We stock standard CWS-compatible hardware, hinges, and common faucet finishes, but full vanities and shower enclosures are ordered to spec after we field-measure your space - no two Miami bathrooms are identical, especially in the pre-1980 stock where walls are rarely plumb. The quote includes delivery lead time so you know when materials arrive before work starts. Call (786) 321-4970 for an exact quote - estimates are free.
