Schluter Bathroom Remodeling: The Fort Myers Owner’s Guide
Most Schluter bathroom remodels in Fort Myers run between $9,000 and $28,000 installed, and the work typically takes our crew five to twelve business days once materials are on site. The most common call we get starts the same way: a homeowner notices grout cracking along the floor-to-wall transition in a shower that’s only a few years old, or spots water staining on the ceiling below a second-floor bath. That’s usually when they discover the waterproofing layer behind the tile wasn’t done right, and they’re now looking at a full Schluter-system replacement rather than a simple patch job.
Which Schluter Models This Applies To
When we talk about Schluter bathroom remodeling, we’re really talking about the KERDI waterproofing system that goes behind the tile. This isn’t a single product with model numbers like a dishwasher. The core components are the KERDI membrane, KERDI-BAND for seams and corners, KERDI-DRAIN for shower bases, and the DITRA uncoupling membrane for floors. If you’ve got an existing Schluter install, check inside your shower valve access panel or behind the escutcheon plate. You’ll often find the orange KERDI fabric visible there, which tells you the original contractor at least used the branded membrane. The compatibility question that trips up most Fort Myers homeowners is whether their tile backer board is actually part of the Schluter system or just a cement board someone slapped KERDI over. KERDI-BOARD is Schluter’s own waterproof foam backer. If you’ve got cement board with KERDI on top, it’ll work, but it’s heavier and holds more moisture in our humidity than the full Schluter assembly. We stock the complete system on our trucks because half the remodels we walk into have a mixed bag of materials that were never going to hold up long-term in Florida.
Signs Your Schluter Bathroom Remodeling Is Failing
- Grout cracking at the wall-to-floor joint. This isn’t just cosmetic. In a Schluter system, movement at that seam means the KERDI-BAND was likely never installed or was installed without proper thinset coverage, and water is now getting behind the waterproofing layer.
- Musty smell you can’t locate. A properly sealed KERDI shower traps moisture inside the enclosure. When the membrane is compromised, that moisture seeps into the wall cavity and feeds mold inside the stud bays, something we find constantly in older Fort Myers homes along the Caloosahatchee where humidity already sits at 80% most mornings.
- Loose or hollow-sounding tiles on the shower floor. This points to the DITRA mat underneath delaminating from the subfloor, which often happens when the original installer used modified thinset over the membrane instead of the unmodified mortar Schluter requires.
- Water staining on the ceiling below a second-floor bathroom. By the time you see a stain on drywall, the leak has usually been active for weeks. The most common source we trace is an improperly sealed KERDI-DRAIN flange that’s been slowly dripping around the drain assembly.
- Efflorescence or white mineral deposits on the tile surface. That chalky white residue means water is migrating through the grout and drying on the surface, pulling minerals with it. It signals that the waterproofing plane behind the tile has failed and moisture is traveling through the assembly unchecked.
Replacement Cost & What’s Included
A full Schluter bathroom remodel through Groundwork Construction Co. in Fort Myers lands between $9,000 and $28,000 installed. Where your project falls in that range depends on square footage, whether we’re doing a walk-in shower or a tub surround, the tile selection, and how much rot repair is lurking behind the old walls once we open them up. Every quote includes demolition to the studs, new KERDI membrane and KERDI-BAND installation with proper seam overlap, a KERDI-DRAIN assembly, DITRA mat on the floor, thinset and grout, and your chosen tile. We write line-item quotes, so when we hand you a number, there are no change orders three days in unless we find framing damage that couldn’t be seen from the surface. That’s rare, but in Fort Myers, where some of these homes saw flood exposure during Ian and the storms that followed, we’re honest about the possibility. The 730-Day Done Right Promise covers the entire install, and Schluter’s own warranty backs the membrane when installed to spec, which is how we do every job. Call (844) 638-7249 for a detailed quote. Estimates are free.
DIY or Call Us?
We’re not going to tell you that you can’t learn to install a Schluter system yourself. The manuals are online, the videos are thorough, and the products are designed to be installer-friendly. What we will tell you is that the single most common mistake we fix is improper seam sealing. KERDI-BAND has to overlap by a full two inches at every transition, and the thinset has to be mixed to a consistency that most first-timers get wrong - too dry and it won’t bond, too wet and the membrane slides. If you’re comfortable pulling a permit, floating a shower pan at the correct 1/4-inch-per-foot slope, and doing flood testing before tile goes up, you can handle it. If any of that makes you pause, call (844) 638-7249. We’ve rebuilt too many DIY showers in Cape Coral and south Fort Myers where the waterproofing looked right from the outside and was absolutely wrong underneath. This isn’t a paint job. A failed Schluter install means water in your framing, and that’s a five-figure mistake.
FAQs
A correctly installed Schluter KERDI shower assembly will last 30 to 50 years in Fort Myers conditions. The membrane itself is polyethylene, which doesn’t rot or break down from moisture exposure. What fails is the installation - the seams, the drain connection, or the substrate underneath. That’s why the labor matters more than the material here.
If the leak is isolated to a single seam and caught very early, a surgical repair is sometimes possible. In practice, by the time a Fort Myers homeowner notices water damage, the moisture has already wicked into the wall cavity and compromised the substrate. We rarely recommend spot repairs because you’re gambling that the rest of the membrane is intact. Most of the time, a full tear-out is the only way to guarantee the problem is solved.

Five to twelve business days on average, start to finish. Smaller walk-in showers with standard tile run closer to a week. Larger bathrooms with custom niches, benches, and intricate tile patterns push toward twelve days. The biggest variable is the 24-hour flood test we perform before any tile goes up. We won’t skip it, and we won’t rush it. If a contractor tells you they can do a full Schluter shower in three days, they’re cutting a corner somewhere.
Yes. We carry KERDI membrane in multiple roll widths, KERDI-BAND, inside and outside corner pieces, KERDI-DRAIN kits in both stainless and matte finishes, KERDI-BOARD in common thicknesses, and DITRA matting as standard truck stock. We also keep unmodified thinset on hand because using the wrong mortar with Schluter products voids the warranty. If your part is something more specific, like a Schluter-KERDI-LINE linear drain or a niche profile, we can usually source it from our Fort Myers suppliers within a day.
