Schluter Bathroom Remodeling: The West Covina Owner’s Guide
A full Schluter bathroom remodel in West Covina typically runs $9,000 to $28,000, depending on shower size, tile selection, and whether we’re replacing the pan, walls, or the entire waterproofing system. We stock Schluter KERDI membrane, KERDI-BOARD, shower pans, and drains on our trucks, so most tear-out-and-replace jobs start within a week of your estimate. Most homeowners call us after they notice grout cracking along the shower floor, a musty smell that won’t quit, or water staining on the ceiling below the bathroom.
Here’s the part most people don’t realize until it’s too late: Schluter systems fail because of installation errors, not product defects. The membrane gets punctured, the seams get lapped wrong, or the drain flange wasn’t set with the right thin-set coverage. When that happens, water works its way behind the tile and into the framing, and by the time you see the stain, the damage is already done. That’s why we insist on Schluter’s own installation specs on every job we touch.
Which Schluter Models This Applies To
We work with the full Schluter line: KERDI waterproofing membrane, KERDI-BOARD wall panels, KERDI-SHOWER-KIT pans and curbs, DITRA underlayment for bathroom floors, and KERDI-DRAIN assemblies. If you’ve got a Schluter strip (the metal trim that seals the edge where tile meets flooring), we can match that too. The compatibility gotcha most people hit: KERDI membrane requires unmodified thin-set to bond to the fleece, but most box stores will sell you modified thin-set with it. That one mistake voids the Schluter warranty and is the leading cause of the failures we tear out in West Covina homes.
For replacements, we always try to match your existing Schluter part first. If we’re repairing a section of KERDI-BOARD, we use genuine Schluter panels because the thickness and fleece density affect how the tile sits. For trim pieces and edge profiles, quality aftermarket equivalents from trusted suppliers work fine and can save you 20 to 30 percent. We’ll tell you which is which before we order anything.
Styles & brands we work with
Signs Your Schluter Bathroom Remodeling Is Failing
- Grout cracking along the shower floor perimeter. This usually means the pan or mortar bed underneath is flexing, which in a Schluter system often traces back to improper slope or thin-set coverage. The crack lets water through, and the waterproofing layer becomes your only line of defense.
- Persistent mildew smell that returns within days of cleaning. Water is sitting somewhere it shouldn’t be, typically behind the tile or trapped between the membrane and the subfloor. No amount of bleach fixes the source.
- Water staining on the ceiling or walls below an upstairs bathroom. By the time paint bubbles, the leak has been active for weeks. We check the drain flange first; that’s the most common slow-leak point on Schluter showers.
- Tile feels spongy or moves when you press on it. The thin-set bond has broken down because the substrate behind it is saturated. In a properly installed Schluter system, the tile should feel dead solid, with zero flex.
- Loose or corroded KERDI-DRAIN grate screws. This is an early warning sign that water is wicking around the drain assembly. Left alone, it accelerates and you end up replacing the entire pan.

AfterReplacement Cost & What’s Included
For West Covina, a Schluter bathroom remodel falls between $9,000 and $28,000 installed. A smaller guest bath or a straight tub-to-shower conversion lands in the $9,000 to $14,000 range. A full master bath gut with KERDI-BOARD walls, new pan, frameless glass, and tile up to the ceiling runs $18,000 to $28,000.
That price includes tear-out of the old shower, disposal, any necessary subfloor or framing repair, the Schluter waterproofing system, tile, grout, sealant, and a written line-item quote before we start. No change orders on square footage we already measured. Our written guarantee covers workmanship for 365 days from the completion date, and if a repair fails within that year, we come back at no charge.
DIY or Call Us?
You can safely check a few things yourself: look for obvious grout cracks, press on tiles to feel for flex, and inspect the drain grate screws. That tells you what’s wrong without risking any damage. What we don’t recommend is cutting into KERDI membrane or removing tile to “see what’s going on.” Once you breach the waterproofing, you’ve created a bigger leak, and Schluter’s warranty is void on any system that’s been modified by someone without proper training.
Isaac Pruett learned to spot these failures on real jobsites across the San Gabriel Valley, and his crews have replaced dozens of Schluter showers in West Covina, including homes near Eastland Center where older framing made waterproofing trickier than the textbook says. If you’re not sure what you’re looking at, call (707) 760-7579 and describe the symptom. We’ll tell you straight whether it’s a $400 fix or a full remodel.
FAQs
A properly installed Schluter system should last 30+ years in West Covina’s climate, which is mild enough that the real threats are install errors, not weather. The failure we see most is 5 to 12 years in, and it’s almost always a drain flange or seam issue. Call (707) 760-7579 if your system is showing signs before decade one.
It depends on where the leak is. Drain flange issues can often be repaired without tearing out the entire shower. A failed seam or punctured membrane behind tile usually means replacing the affected wall section or the whole pan. We’ll give you an honest answer after inspection, not a sales pitch for work you don’t need.
Most Schluter bathroom remodels take 2 to 4 weeks, depending on shower size and tile complexity. Demolition and waterproofing are days 1 through 3; tile work and grout curing take the bulk of the schedule. We’ll give you a written timeline before we start, with a phone call if anything shifts.
Yes, we carry KERDI membrane, KERDI-BOARD, shower pans, drain assemblies, and edge profiles on most trucks, which means we can often start the repair the same week. We also stock parts for KraftMaid, Cambria, and Silestone projects, so if your bathroom touches any of those brands, we can source what we need without delaying your job.
If your Schluter shower is leaking, cracked, or just not draining right, call (707) 760-7579 for a free estimate. You should know what you’re getting before we ever pick up a tool.
