GAF Bathroom Remodeling: The Dallas Owner’s Guide
A full GAF bathroom remodel in Dallas typically runs $9,000 to $28,000 installed, depending on the scope, the materials you choose, and how much of the existing plumbing and waterproofing needs to be redone. We stock and install GAF-compatible bathroom systems and work with GAF roofing products where they overlap in remodel scope, so you’re not waiting on a distributor to ship something across the country. Most Dallas homeowners call us when they’ve got a shower pan that’s been seeping for months, tile that’s cracked loose from water damage, or a bathroom that was originally built with materials that were never meant for the humidity swings we get here.
Here’s what we see often: a homeowner notices a soft spot in the subfloor near the tub, or mildew that keeps coming back no matter how much they scrub. By the time it’s visible, the waterproofing layer underneath has usually been compromised for a while. That’s the failing part, and it’s the piece nobody sees until it’s too late.
Key takeaways:
- GAF bathroom remodels in Dallas: $9,000 to $28,000 installed
- We are an independent contractor, not affiliated with GAF
- Written price before any work starts, every time
- You’ll know exactly who’s coming: name, photo, uniform, badge
Which GAF Models This Applies To
When Dallas homeowners ask about GAF bathroom remodeling, they’re usually working with one of two situations. First, they have GAF roofing products and want a contractor who already understands the GAF system when a remodel touches an exterior wall or roofline near a bathroom. Second, they’re using GAF’s Deck-Armor or WeatherWatch underlayment as part of a larger bathroom addition or gut remodel where moisture management matters at the framing level.
The compatibility gotcha we see in Dallas: GAF makes roofing-specific waterproofing products that are excellent at what they do, but bathroom waterproofing requires different products rated for continuous wet conditions inside the structure. If a previous contractor used roofing underlayment inside a shower surround or under a bathroom floor, that’s a problem. Roofing underlayment is designed to shed water that flows downhill. Bathroom waterproofing has to handle standing water, steam, and capillary action in a confined space. We identify the right material by checking the product label on what’s currently installed and measuring the exposed area, then matching it to a bathroom-rated membrane or system.
OEM versus aftermarket matters here. For GAF products still under warranty, you want OEM material or the warranty gets voided. For bathroom components that GAF doesn’t manufacture, we use specification-grade material from partners like Schluter, Kohler, and Moen. We also stock parts for KraftMaid cabinetry, Cambria, and Silestone surfaces, so a full bathroom package doesn’t have to come from five different suppliers.

Signs Your GAF Bathroom Remodeling Is Failing
- Grout that keeps cracking or falling out in chunks. This usually means the substrate behind the tile is moving, and movement is how water gets in. Once water is behind tile in a Dallas bathroom, the damage spreads through the drywall and into the framing.
- A shower pan that holds water or drains slowly. If the pan isn’t sloped correctly, water pools in the corners and eventually soaks through. We’ve pulled pans in Oak Cliff where the subfloor underneath was rotted to the point you could push a screwdriver through by hand.
- Mildew or a musty smell that returns within days of cleaning. That smell is coming from inside the wall or under the floor. Cleaning the surface doesn’t touch the source.
- Floor tile that feels soft or has a slight bounce when you step on it. That’s structural. The subfloor is compromised and the tile is the only thing holding up. It’s a full replacement, not a repair.
- Caulk or sealant around the tub that peels, cracks, or turns brown. Brown discoloration means water is getting behind the seal and feeding mold. Sealing over it just traps the water in place.

AfterReplacement Cost & What’s Included
A GAF bathroom remodel in Dallas lands between $9,000 and $28,000. The spread comes down to three things: the size of the bathroom, the materials you pick, and how much hidden damage we find once the old surfaces come off. Here’s how it breaks down:
| Scope | Dallas Installed Range |
|---|---|
| Full bathroom remodel (standard 5×8) | $9,000 – $15,000 |
| Full bathroom remodel (larger or custom) | $15,000 – $28,000 |
| Walk-in shower installation | $4,500 – $12,000 |
| Tub-to-shower conversion | $3,500 – $10,000 |
| Shower replacement | $3,000 – $8,500 |
| Bathroom vanity installation | $800 – $3,000 |
Every quote we write includes materials, labor, demo, disposal, waterproofing, and the finished surfaces. We don’t write a number and then add line items later. What’s on the written price is what you pay, and if we find hidden damage during demo, we show you what we found before we touch anything else.
The 365-Day Done Right Promise applies to every bathroom remodel we complete. If something isn’t right within a year of the completion date, we fix it at no charge. That’s written into the guarantee, not added as a goodwill gesture.
DIY or Call Us?
The honest answer is that any bathroom remodel involving existing water damage, tile removal, or waterproofing is not a weekend project. What you can safely do: inspect visible caulk and grout for gaps, check for soft spots in the floor, and look under the vanity for signs of water staining. What goes wrong with DIY is when a homeowner pulls up a tile, finds rot, and keeps going without addressing the waterproofing underneath. Then they re-tile over a compromised surface and the whole cycle starts again six months later.
Waterproofing is not a place to learn as you go. A shower that leaks into the wall cavity can rot framing, grow mold, and require structural repair that costs far more than the original remodel. If water is already involved, or the subfloor feels soft, that’s the line where you stop and make the call.

FAQs
A properly installed bathroom remodel with correct waterproofing and specification-grade materials will last 25 to 30 years in Dallas before the surfaces show meaningful wear, and longer if you keep the ventilation in good shape. The Texas humidity and the hard water we get from municipal supplies shorten the life of sealants and finishes, so expect to re-caulk every few years regardless. Call (432) 302-8761 and we’ll walk through what to expect for your specific bathroom.
In most cases we can replace the shower pan and the lower course of tile without redoing the entire bathroom, as long as the water damage hasn’t spread into the surrounding walls or subfloor. That typically runs $3,000 to $8,500 in Dallas depending on the pan type and what’s underneath. If the subfloor is compromised, a partial repair won’t hold, and we’ll show you exactly what we found before recommending the larger scope.
Most Dallas bathroom remodels take two to four weeks from demo to finish, depending on scope and what we find behind the old surfaces. A tub-to-shower conversion is usually closer to one week. A gut remodel with a custom shower, new vanity, and moving plumbing lines runs four to six weeks. We’ll put the timeline in the written estimate before any work starts.
We keep common waterproofing membranes, Schluter trim strips, and standard tub and shower components on hand in our Dallas shop, and we order model-specific materials per job to match your exact layout and finishes. That keeps you from paying for excess inventory and keeps us from installing whatever happens to be on the shelf. Call (432) 302-8761 and we’ll tell you what’s in stock for your scope.
