Tamko Bathroom Remodeling: The Fort Worth Owner’s Guide
Bathroom remodeling with Tamko waterproofing and backer board systems in Fort Worth typically runs $9,000 to $28,000 installed, depending on shower size, substrate condition, and whether you’re replacing the pan, the walls, or both. We stock Tamko-compatible shower systems and waterproofing membranes on our trucks, and Curtis Lane can usually diagnose the failure site the same day we walk the job. Most owners catch the problem after they notice loose grout, a soft spot under the tile, or a water stain bleeding through the ceiling below the bathroom – that’s the Tamko layer telling you it’s been compromised.
Bradford Remodeling Co Fort Worth is an independent remodeling contractor. We install and repair Tamko shower waterproofing as part of full bathroom remodels, but we are not a Tamko dealer or manufacturer affiliate. What that means for you: we match the existing Tamko system to the correct replacement membrane and substrate, we quote the whole job in writing before we start, and the work carries the 365-Day Done Right Promise.
Key Takeaways:
- Tamko bathroom remodel costs in Fort Worth: $9,000 – $28,000 installed.
- The most common failure point is the seam between the wall board and the shower pan, especially in slab-on-grade homes common across Fort Worth.
- We stock Tamko-compatible membranes, bonding adhesive, and seam tape on our trucks, so most repairs don’t wait on a parts order.
- Written price before any work starts. No numbers that move at the door.
- 365-Day Done Right Promise: if the work fails within one year, we return and correct it at no charge.
Which Tamko Models This Applies To
Tamko makes several waterproofing and backer products that show up in Fort Worth bathrooms, and the right repair depends on which system is behind your tile. The two we see most often are Tamko’s waterproofing membrane – a sheet-applied barrier that goes behind tile in shower walls and tub surrounds – and Tamko’s cement backer board, which serves as the rigid substrate in wet areas. Some Fort Worth homes built in the last 10 to 15 years used Tamko’s composite underlayment under floor tile in the bathroom as well.
Here’s the compatibility gotcha most homeowners don’t know: Tamko’s shower membrane requires a specific bonding adhesive and seam tape. You cannot seal the seams with standard thin-set or an off-brand seam product and expect the waterproofing to hold. If whoever built your shower cut that corner – and we’ve seen it more than once in Fort Worth track homes – the waterproofing fails at the corners and along the curb first. That’s exactly where water finds the framing.
To identify what you have, look for a gray or black sheet membrane behind loose tile at the edge of the shower, or ask your remodeler to pull the escutcheon plate off the shower valve. You’ll usually see the Tamko logo printed on the face of the membrane. If you have the original build sheet or the previous contractor’s material list, that’s even better – it’ll tell us the exact product line and thickness. When the original material isn’t identifiable, we default to a full replacement of the shower waterproofing system rather than patching a mystery substrate. Patching blind is how you buy the same leak twice.
For the parts decision: Tamko’s OEM membrane and seam tape are what we recommend when the shower is otherwise sound and the failure is localized. Quality aftermarket equivalents exist and can save $200 to $400 on materials, but they don’t carry the same manufacturer spec for adhesion over cement board. If the job is a full tear-out – which it often is once water has reached the framing – we spec the OEM membrane every time. The material cost difference is small compared to the labor of doing the job twice.
Styles & brands we work with
Signs Your Tamko Bathroom Remodeling Is Failing
- Loose or cracked grout at the shower floor corners. This is usually the first visible symptom. Water gets behind the tile, the substrate swells or flexes, and the grout line cracks. The Tamko membrane may still be intact – but if you wait, it won’t be.
- A soft spot in the shower floor or around the drain. This means the substrate – the material under the tile – has already absorbed water and is beginning to rot or delaminate. By the time you feel softness, the waterproofing has been breached for a while.
- Water stains or peeling paint on the ceiling directly below an upstairs bathroom. This is the classic sign that water has passed through the entire Tamko system and is now traveling along the subfloor. In two-story Fort Worth homes, the stain usually appears weeks before any tile problem is visible in the bathroom itself.
- A musty smell that won’t quit, even after cleaning. That’s mold feeding in the wall cavity. The waterproofing has failed, the framing is wet, and the smell is coming from inside the wall, not from the surface.
- Tile that sounds hollow when you tap it. Tap the shower wall tiles with the handle of a screwdriver. A sharp, solid sound is good. A hollow thud means the tile has separated from the substrate – a clear sign the Tamko membrane has lost its bond behind the tile.
Replacement Cost & What’s Included
A Tamko bathroom remodel in Fort Worth runs $9,000 to $28,000 installed, and the spread comes down to three things: the size of the wet area, what’s behind the tile, and whether the shower pan needs replacing.
| Scope | Fort Worth Installed Range |
|---|---|
| Full bathroom remodel (5×8, standard tub/shower) | $9,000 – $14,000 |
| Full bathroom remodel (larger footprint, walk-in shower) | $12,000 – $20,000 |
| Tub-to-shower conversion with Tamko waterproofing | $3,500 – $10,000 |
| Walk-in shower installation, waterproofed and tiled | $4,500 – $12,000 |
| Complete tear-out to studs, re-waterproof, rebuild | $18,000 – $28,000 |
What drives the range: if the original waterproofing failed and the framing is rotted, the job goes from a surface remodel to a structural repair. We have to cut out the damaged studs, sister new framing, then rebuild the waterproofing assembly from the studs out. Floor joists and wall studs in Fort Worth slab homes take a beating because the shower pan and wall membrane are the only thing between the tile and the structure – there’s no basement to catch the leak, so the water sits in the framing.
Every bid includes parts, labor, demolition, disposal, and the written 365-Day Done Right Promise. We give you the price before any work starts, in writing, and that number does not move unless you change the scope. Straight scope, firm price, no surprises at final walkthrough.

Here’s the honest split. If you have a leaking shower valve or a cracked escutcheon plate, you can safely check the area behind the plate for visible water damage – that’s a five-minute inspection that helps us quote the job accurately. What you should not do is cut into the shower wall or try to patch a Tamko membrane yourself. The membrane is a continuous waterproof barrier. A patch that doesn’t bond correctly creates a false confidence, and the water keeps eating the framing behind the patch.
Water and tile work go wrong expensively. If the shower pan slope is off even an eighth of an inch, water pools and the new waterproofing fails the same way the old one did. If the bonding adhesive is mixed or applied wrong, the membrane peels off the cement board inside a year. We do this work with the correct Tamko-spec materials and we stand behind it for a full year in writing. If you’re in Fort Worth and you suspect the Tamko layer in your bathroom has failed, call us at (682) 204-4897 and we’ll put a number on it before any work starts.
FAQs
A properly installed Tamko membrane over sound substrate in a Fort Worth bathroom typically lasts 15 to 25 years before the first signs of seam fatigue show up. Texas heat and the constant expansion and contraction of slab-on-grade framing take their toll on all shower waterproofing – the corners and the shower curb are where Tamko systems tend to fail first in the Fort Worth market. If you’re past year 15 and seeing grout cracks at the floor corners, it’s time for an inspection.
Yes, if the failure is localized – a seam separation along one wall or a breach around the valve opening – a targeted repair with OEM Tamko seam tape and proper bonding adhesive can restore the waterproofing. But if the substrate behind the membrane is wet or rotted, a patch job won’t hold. The determining factor is what the framing looks like once we expose it. Call (682) 204-4897 and Curtis can assess whether a repair or a full replacement is the honest option for your shower.
A full shower waterproofing replacement with new tile typically takes 5 to 10 working days, depending on the drying time required for the substrate and membrane adhesive. Demolition day is day one, waterproofing goes in on day two or three, and the tile, grout, and fixtures follow. We don’t rush the cure times – the adhesive and membrane need proper drying conditions to hold their bond. A targeted seam repair can be done in one day if the substrate is dry.
Yes. Our trucks carry Tamko-compatible membrane, seam tape, and bonding adhesive, along with the cement backer board and substrates we use for replacement work. We also work with documented material brands like KraftMaid, Cambria, and Silestone for vanities and surfaces when the job includes them. If your repair needs a special-order Tamko product, we’ll tell you the lead time before we quote the job, not after.
