Tamko Bathroom Remodeling: The Jacksonville Owner’s Guide
Tamko bathroom remodeling in Jacksonville typically runs $9,000 to $28,000 installed, depending on the size of the bathroom, what’s behind the walls, and whether you’re replacing or reworking the layout. We stock and install Tamko-compatible waterproofing, backer board, and shower system components, and most common failures can be addressed the same week we assess the scope. Where most homeowners discover a problem is at the tile line: grout cracking, a soft spot in the substrate near the drain, or water staining on the ceiling of the room below. That’s the moment the failure stops being a cosmetic issue and becomes a plumbing and structural one.
If you’re reading this, the problem probably already announced itself. Water found a seam, a pan cracked, or the waterproofing behind the tile gave out years ago and the damage is only now showing through. Either way, you need a straight answer on what it costs to fix and whether the rest of that bathroom is worth saving. That’s what this page is for.
Which Tamko Models This Applies To
Tamko builds a range of bathroom-specific products, but the parts that generate the most service calls fall into three categories: waterproofing membranes, shower pan liners, and composite backer board used as a tile substrate. If you’re trying to match a failing part, start with the label or stamp on the original product. Tamko waterproofing membranes are printed with the product identifier along the selvage edge. The backer board carries a manufacturer stamp on the board face, usually visible when you pull a section of tile and the thinset comes off clean.
Here’s the compatibility gotcha most homeowners run into: Tamko’s shower waterproofing and pan liner systems are engineered to be used as a complete assembly. Mixing a Tamko membrane with a different manufacturer’s drain assembly or corner dam will typically void any material warranty and, more importantly, create a seam that is only as strong as whoever installed it. If you’re replacing a failed section, the right move is a full system match. We stock Tamko-compatible waterproofing and substrate materials on our trucks, and we also install quality aftermarket equivalents where the original product line has been discontinued. Curtis Lane will tell you the same thing he tells every Jacksonville homeowner: if the material spec isn’t traceable, the tile job on top of it is a gamble.
Compatibility note worth filing away: Tamko’s thinner 1/4-inch backer board is fine for wall tile, but it lacks the rigidity required for a shower floor. If someone installed 1/4-inch board under a pan, that’s a failure waiting to happen in any Jacksonville home where humidity pushes through the structure every summer.

Signs Your Tamko Bathroom Remodeling Is Failing
- Recurring grout cracks along the shower floor perimeter. This usually means the pan underneath is flexing, not that the grout is bad. Re-grouting without fixing the substrate means you’ll see the same cracks again inside a year.
- A soft, spongy spot in the tile floor near the drain or toilet flange. The substrate underneath is waterlogged. In Jacksonville’s humidity, once moisture gets between the tile and the backer board, it can sit there for months before you feel it through the tile.
- Dampness or water staining on the ceiling below a second-story bathroom. The waterproofing membrane has failed along a seam or around the drain assembly. By the time you see this, the repair scope usually includes ceiling drywall, framing inspection, and membrane replacement.
- A persistent musty odor that doesn’t clear when the bathroom is ventilated. Odor means organic material, typically the wood substrate or stud bays behind the tile, is holding water. This is a mold condition and a structural one, not just a smell.
- Loose tiles with thinset still attached to the back. The bond between the backer board and the thinset failed because the board surface is compromised. In Tamko systems, this usually traces back to a bad seam seal or a sheet that was installed over an unsupported gap.

AfterReplacement Cost & What’s Included
For a full bathroom remodel on a Tamko-specified system, Jacksonville homeowners should expect $9,000 to $28,000 installed. The range covers the difference between a modest guest bath where the footprint stays put and a master bath with a walk-in shower, tile to the ceiling, and a pan rebuild. Here’s how that typically breaks down:
| Scope | Installed Price Range |
|---|---|
| Partial substrate repair + re-tile shower floor | $3,000 – $8,500 |
| Full waterproofing replacement + new pan and wall tile | $9,000 – $18,000 |
| Complete bathroom remodel, Tamko-compatible system, mid-range finishes | $18,000 – $28,000 |
What drives the cost in Jacksonville is what we find once the old tile comes off: wood framing that needs sistering, drain assemblies that are no longer code-compliant, or previous work that was never flashed correctly. We price every job with a written quote before any work starts, and that number holds unless the scope genuinely changes. No door pricing, no surprise line items at closeout. Every completed job carries the 365-Day Done Right Promise: if the repair or remodel fails inside the guarantee window, we come back and correct it at no charge.
DIY or Call Us?
This is the point where most Tamko-informed homeowners ask whether they can patch a failed membrane themselves. You can inspect a few things safely: pull the escutcheon plate off the shower valve and look for water staining in the wall cavity, or check the ceiling below for active moisture with a basic pin meter. What should not be a DIY job is any repair that involves opening the waterproofing layer. That membrane is a single, continuous surface when it was installed correctly. Cutting into it to “patch” a seam means you now have two seams where you used to have one, and neither will be as strong as the original. The substrates behind it should be dry and structurally sound before a single tile goes back. We see failed patch jobs in Riverside, San Marco, and along the beaches every month, where a homeowner spent a weekend and three hundred dollars to create a problem that costs ten times that to undo.

FAQs
How long does Tamko waterproofing last in a Jacksonville bathroom?
A properly installed Tamko-compatible membrane and pan system typically lasts 15 to 25 years in Jacksonville’s climate, but the failure point is almost always the installation seams and corners, not the material itself. Proper substrate prep and a dry, clean bonding surface are what determine whether you get 10 years or 25.
Can a failed Tamko shower pan be repaired without replacing the whole bathroom?
In most cases, yes, a failed pan can be replaced without gutting the whole bathroom, provided the surrounding walls and framing are still sound. The repair scope typically includes removing the lower rows of tile, pulling the old pan, rebuilding the sloped mortar bed, installing the new Tamko-compatible liner, and re-tiling the affected area. Partial repairs run roughly $3,000 to $8,500 in Jacksonville.
How long does a Tamko bathroom repair or remodel take?
A partial pan and membrane repair runs three to five working days including dry time between membrane layers. A full bathroom remodel runs two to five weeks depending on tile scope, plumbing moves, and whether we find framing damage. We’ll give you a working schedule in writing before we start.
Do you stock Tamko parts, or do I have to order them myself?
We stock Tamko-compatible waterproofing membranes, backer board, and shower pan components on our service trucks, and we pull from a documented roster of name-brand materials including Kohler and Moen fixtures, Cambria and Silestone surfaces, and KraftMaid cabinetry. If a discontinued Tamko part needs a matched equivalent, we source the aftermarket part through our supply chain and verify the spec before it goes in.
