Tamko Bathroom Remodeling: The West Palm Beach Owner’s Guide
We stock and install Tamko-compatible bathroom remodeling materials throughout West Palm Beach, with full bathroom remodels typically running $9,000 – $28,000 depending on size, materials, and the condition of what’s behind the walls. Most Tamko owners call us because they’ve spotted water staining on a ceiling below the bathroom, loose tiles near the tub flange, or a shower pan that’s started to flex underfoot. What they’re describing is almost always a failure at the waterproofing layer, not the surface tile, and that distinction matters when we scope the fix.
We’re an independent remodeling contractor, not affiliated with Tamko. But we work with Tamko waterproofing membranes and backer materials often enough to know their installation quirks, their failure patterns in Florida humidity, and what a proper repair actually involves. The crew Graham Stein sends to a Tamko bathroom job will name the membrane, the mortar, and the exact steps before the first tile comes up.
Which Tamko Models This Applies To
Tamko’s bathroom product line centers on waterproofing membranes and backer boards rather than a single “model” the way a faucet or toilet has a model number. The materials we most often replace or reinstall in West Palm Beach homes are Tamko’s sheet membrane systems and their cement backer products, typically identified by the printed markings on the membrane edge or the stamp on the backer board face. If you’ve got the original project paperwork, the product name will be on the material schedule. If not, a photo of the exposed membrane or backer edge is usually enough for us to identify what’s installed.
Here’s the compatibility gotcha most homeowners don’t know: Tamko’s waterproofing membrane is not interchangeable with the liquid-applied systems some crews use. You cannot patch a Tamko sheet membrane with a brush-on liquid membrane and expect the seam to hold. The repair has to tie into the existing sheet with the correct joint treatment, and in South Florida, a failed seam is the difference between a repair that lasts fifteen years and one that starts leaking again in two. We stock the Tamko-compatible sheet products and joint treatments on the truck for this reason. When a homeowner asks whether an aftermarket membrane will work, our answer is always the same: for a wet area, use the system the manufacturer specifies. The savings on an off-brand membrane never cover the cost of tearing out a shower twice.
Styles & brands we work with
Signs Your Tamko Bathroom Remodeling Is Failing
- Water staining on the ceiling below the bathroom. This usually means the waterproofing layer has a breach at a seam or corner, not that the tile itself failed. By the time the stain shows, the leak has been running inside the floor assembly for weeks or months. In West Palm Beach’s humidity, that trapped moisture feeds mold fast.
- Loose or hollow-sounding tile near the tub or shower base. A hollow tap means the thin-set has lost its bond to the backer board. In a properly waterproofed Tamko system, water never reaches the backer; when it does, the mortar breaks down and tile starts to move. Loose tile is the symptom, not the cause.
- Grout that stays dark or wet-looking long after the shower dries. Grout is not waterproof, and it’s not supposed to be the waterproofing layer. If grout is absorbing water and not drying, the membrane underneath isn’t doing its job. Dark grout that never fully dries is a moisture-retention signal, and in Florida that becomes a mold issue quickly.
- A shower pan that flexes or creaks underfoot. A properly set pan on a solid bed should not move. Flex means the substrate has decayed or the pan wasn’t bedded correctly. Either way, the structural layer under the tile is compromised, and continued use will crack the tile and worsen the leak.
- Musty odor that returns days after cleaning. A persistent organic smell in a bathroom usually means water is trapped somewhere it shouldn’t be, behind tile or inside a wall cavity. Cleaning the surfaces won’t fix it. The source is almost always at the waterproofing layer or a failed seal at the drain or flange.

AfterReplacement Cost & What’s Included
A full Tamko bathroom remodel in West Palm Beach runs $9,000 – $28,000. A smaller repair, like re-waterproofing a shower pan or replacing a cracked membrane section before new tile goes in, falls in the $4,500 – $12,000 range depending on how much of the wall assembly has to be rebuilt. The range is driven by the size of the wet area, whether the studs and subfloor are sound, and the finish materials the family picks. A 5-by-8 guest bath with basic tile and a fiberglass pan sits at the lower end. A master bath with a custom walk-in shower, full-height tile, and a glass enclosure lands closer to the top.
Every estimate comes as a written line-item scope before any work starts. Labor, materials by brand and quantity, and a firm start and end window are all in writing. The man who grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College still walks every job site himself before a single drop cloth goes down. And every completed project carries the 365-Day Done Right Promise: if it’s not done right, we make it right.
DIY or Call Us?
What you can safely do yourself is document the problem: take photos of the staining, the loose tile, the wet grout, and note how long the shower has been showing symptoms. That helps us scope the job before we arrive. What you should not do is open the wall or pull tile to “see how bad it is.” The moment a waterproofing layer is breached, water has a new path into the framing, and a small repair becomes a full rebuild. Behind a shower wall in a West Palm Beach home, you’ll often find plumbing and electrical lines sharing the same stud cavity. One wrong cut with a reciprocating saw becomes a much larger problem than the tile ever was.
If the tile is already loose, stop using the shower and call us at (728) 203-3270 for a free estimate. We’ll get eyes on it, name the failure, and put the fix in writing before anything gets torn out.
FAQs
Installed correctly, a Tamko membrane should last the life of the tile installation, typically 15 – 25 years before the surface is redone for reasons unrelated to waterproofing. What shortens that lifespan in Florida is not the product but the installation: poor seam treatment, wrong thin-set, or a compromised drain seal. We’ve seen correctly installed Tamko systems in Flamingo Park homes still dry and sound at 20 years, and we’ve seen five-year-old failures where a seam was rushed. If you’re wondering whether a full re-tile is needed, call (728) 203-3270 and we’ll tell you straight what the membrane condition actually is.
Sometimes, but only if the failure is localized and the surrounding membrane is still sound. A corner seam that was never properly sealed can be repaired by opening that section, re-treating the joint, and re-tiling that area. A membrane that’s been broadly compromised, or one where the backer board behind it has begun to rot, means a full wet-area rebuild. The honest answer requires opening a wall, and that’s a job for a trained eye. Estimates are free, and we stock the Tamko-compatible joint treatments on the truck.
A full wet-area replacement, from demo through grout and trim, typically runs 7 – 10 working days in a West Palm Beach home. A smaller repair like a pan replacement or membrane patch can take 3 – 5 days including tile setting and curing time. The schedule is written into the scope before work starts, and we hold to quiet hours when children are sleeping or doing schoolwork. Call (728) 203-3270 and we’ll give you a real timeline for your specific bathroom.
Yes. Our crews keep Tamko-compatible sheet membranes, backer board, joint treatments, and drain assemblies stocked for the West Palm Beach service area. We also work with named brands across the rest of the bathroom: cabinets from KraftMaid, countertops from Cambria and Silestone, and fixtures from Kohler, Moen, and Grohe. If your remodel calls for a material we don’t stock, it’s ordered and scheduled before we open the first wall, so the job doesn’t stall mid-project.
Your Tamko bathroom has one job: keep water where it belongs. When it stops doing that, the fix should be specific, written, and done by a crew that leaves the floor cleaner than they found it. Call (728) 203-3270 for a free estimate, or stop by our West Palm Beach office. Graham Stein will walk you through exactly what’s failing, what it costs, and how we protect the rest of the house while we rebuild the wet area. Put it in writing, then do exactly that.
