Schluter Bathroom Remodeling: The West Covina Owner’s Guide
Schluter bathroom remodeling in West Covina typically runs $9,000 to $28,000 installed, depending on the waterproofing system, shower footprint, and how much of the original tile needs to come out. We stock Schluter KERDI membrane, DITRA underlayment, edge trim, and shower bases on our trucks, so most West Covina jobs start within a week of your written quote. The owners who call us usually say the same thing: the grout started staining dark around the pan, a tile cracked along the curb, or the shower floor felt soft underfoot. What they’re describing is a waterproofing failure, not just a cosmetic one.
We’re Sawyer Remodel West Covina, an independent remodeling contractor that works with Schluter products daily. We’re not affiliated with Schluter Systems, but we’ve installed their waterproofing across West Covina for years, including tight-footprint bathrooms near the South Hills area where every inch of mud bed counts.
Which Schluter Models This Applies To
Most West Covina homes built or remodeled in the last 15 years use one of three Schluter systems: the KERDI shower kit (foam tray, membrane, and curb), the DITRA uncoupling mat under floor tile, or KERDI-BOARD as a backer panel instead of cement board. The failure point determines which part you’re actually replacing, and it’s rarely the one homeowners think it is.
Here’s the compatibility gotcha: Schluter’s foam shower trays come in specific drain locations (center, offset left, offset right) and specific slope ratios. You cannot trim the tray unevenly to make a drain fit, that ruins the 1/4-inch-per-foot slope and voids the waterproofing warranty. If your drain moved even 2 inches during the original install, the tray won’t drain right and water sits, which is exactly how soft shower floors start. We measure and order the correct tray for every West Covina job, or we float a traditional mud bed when a custom size makes more sense.
For OEM versus aftermarket parts: Schluter’s KERDI membrane and DITRA mat don’t have decent aftermarket equivalents. The fleece-to-plastic bond is what tile grabs onto, and knockoff membranes delaminate. We use genuine Schluter sheet goods. Edge trims and shower grates, on the other hand, have quality third-party options that fit the profile channels and save real money, so we offer both and price them honestly.

Signs Your Schluter Bathroom Remodeling Is Failing
- Dark grout lines along the shower pan edges or curb. This is water wicking up behind the tile, meaning the bond between the membrane and the drain assembly has broken somewhere. The grout darkens first, then the tile starts moving.
- A shower floor that flexes or feels spongy underfoot. Schluter foam trays are rigid when installed correctly. Movement means water has rotted the plywood subfloor underneath, and the tray is no longer bearing on solid structure.
- Caulk or grout cracking at the change-of-plane corners. Schluter specifies KERDI-FLEX or band at every corner and seam. When corners crack open in under a decade, someone skipped the band or used drywall mesh instead of membrane, and that’s a tear-out-and-redo waterproofing fix.
- Efflorescence, that white chalky crust, on the tile or grout. Water is traveling through the mortar bed and evaporating through the tile surface, carrying minerals with it. In West Covina, our hard water accelerates this once a leak starts.
- A musty smell that won’t leave even after cleaning. The water proofing failure is inside the wall or under the tray, and mold is growing where you can’t see it. By the time you smell it, the framing is involved.

AfterReplacement Cost & What’s Included
A full Schluter bathroom remodel in West Covina runs $9,000 to $28,000. The range comes down to three things: whether we’re doing a gut-and-rebuild (new waterproofing from the studs out) or a partial repair, the shower footprint, and your finish choices, tile, glass, fixtures from Kohler or Moen, and the trim package.
Here’s how the numbers break down in this market:
- Shower pan waterproofing repair: $3,000 to $8,500 when the floor has failed but walls are intact. This usually means pulling the pan, bottom rows of tile, and the first 12 inches of wall membrane, then reinstalling with new KERDI.
- Full Schluter shower rebuild: $9,000 to $18,000, including KERDI waterproofing, new pan, tile, glass door, and fixtures. Most West Covina master baths fall in the middle of this range.
- Complete bathroom remodel with Schluter throughout: $15,000 to $28,000. This covers the shower, floor with DITRA underlayment, new vanity, lighting, and plumbing trim-out.

And every Schluter job carries our 365-Day Done Right Promise: if the waterproofing fails or the tile moves within a year, we make it right on our dime.
DIY or Call Us?
You can check a few things yourself. Look at the grout around the drain with a flashlight. Press the shower floor with your heel and listen for movement. Check if the escutcheon plate behind the shower handle sits tight against the tile or gaps out. Those clues tell you what’s failing.
What you shouldn’t try is pulling tile to inspect the membrane underneath. Schluter systems work as one continuous waterproof envelope, and cutting into it without knowing where the seams, corners, and drain collar sit is how a $3,000 repair becomes a $15,000 gut job. Waterproofing demands real experience, and a failed Schluter install is where hidden water has already done damage you can’t see until it’s opened up.
Luca Romano grew up in East Los Angeles and has been pulling permits and finishing bathrooms across West Covina for years. He trained in construction technology at LA Trade-Tech and has torn out enough failed pans to know what hides behind the tile. Good work shows. Bad work shows up later.

FAQs
A properly installed Schluter KERDI shower system lasts 25 to 50 years, because the waterproof membrane is the structural layer, not the tile or grout. In West Covina’s dry climate, what shortens lifespan is hard water mineral buildup pushing grout failure and silicon breakdown at corners, so seal grout every 3 to 5 years and regrout the pan when colors start darkening. Call (341) 217-4204 and we’ll tell you whether your shower needs sealing or repair.
Yes, in most cases we repair only the failed section, whether that’s a pan, curb, or one wall. If the membrane has failed at the drain or a corner seam, the damaged area gets opened, dried, and re-waterproofed with new KERDI before retiling to match. Call (341) 217-4204 for a free inspection and a repair quote that doesn’t push you into a remodel you don’t need.
Most Schluter shower replacements take 3 to 5 working days, including demo, waterproofing, tile, grout, and plumbing trim. The mud bed or foam tray needs overnight cure time before the next layer goes down, so it’s never a same-day job. Call (341) 217-4204 and we’ll give you a day-by-day schedule in writing before we start.
Yes, our West Covina crews carry KERDI membrane rolls, DITRA mat, KERDI-BAND, inside and outside corners, drain collars, and edge trim profiles on every truck. That means the most common waterproofing repairs start the day you approve the quote, with no two-week wait on parts. Call (341) 217-4204 for a free estimate and we’ll confirm the exact part on-site.
We also remodel with KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Toto fixtures, so your Schluter shower can be paired with materials that last as long as the waterproofing behind them.
