IKO Bathroom Remodeling: The Houston Owner’s Guide
IKO bathroom remodeling in Houston typically runs $9,000 to $28,000 installed, depending on whether you’re replacing a failed shower pan, rebuilding a water-damaged substrate, or doing a full gut-and-rebuild. We stock the common IKO-compatible waterproofing membranes, backer boards, and drain assemblies on our trucks, so most IKO shower and tub surround repairs start the same week you call. Most Houston homeowners discover an IKO part has failed the hard way: a soft spot in the floor outside the shower, water staining on the ceiling below, or grout that keeps cracking no matter how many times it’s re-caulked.
Bradford Remodeling Co Houston is an independent contractor. We’re not affiliated with IKO, but we’ve worked on enough IKO-spec bathrooms across Harris County to know exactly how these systems fail in our climate and what it costs to make them right.
Key Takeaways:
- Full IKO bathroom remodel in Houston: $9,000 – $28,000 installed, with a written price before we start
- Most failures trace back to water intrusion at the curb, the drain flange, or the wall-to-pan junction
- Every job carries the 365-Day Done Right Promise in writing

Which IKO Models This Applies To
IKO manufactures roofing and waterproofing products, and in bathrooms their membranes and underlayments most often show up beneath tile showers, tub surrounds, and bathroom floors where a previous contractor used IKO’s waterproofing sheet goods or rolled membranes as the moisture barrier. The specific product line matters: IKO’s self-adhered waterproofing membranes come in different thicknesses and roll widths, and the compatibility question is always about what’s underneath the tile, not the tile itself.
Here’s the Houston-specific gotcha most homeowners don’t know: IKO membranes that perform fine in dry climates struggle when they’re installed over a substrate that wasn’t sloped correctly or when the membrane wasn’t lapped up the walls far enough. Houston’s humidity doesn’t cause the failure directly, but it slows drying time dramatically, which means a small leak becomes a mold and rot problem faster than it would in a drier market. When we open up a failed IKO shower in Spring Branch or Sugar Land, the failure point is almost always at a seam, a corner, or the drain collar, not in the middle of the membrane itself.
The OEM-versus-aftermarket decision depends on the age of the install and what IKO was actually used for. If the original contractor used an IKO peel-and-stick membrane as the pan liner, we usually replace the entire waterproofing assembly rather than patch it, because the labor to expose the failure is the same either way and a patched membrane carries no warranty from anyone. For wall applications, quality aftermarket sheet membranes from manufacturers like Schluter or Laticrete are a direct upgrade and we specify them openly when the original IKO material isn’t the right call to re-install.

Signs Your IKO Bathroom Remodeling Is Failing
- Grout cracking repeatedly along the floor-to-wall joint. This is the classic tell that water is getting behind the tile and the substrate is swelling. The grout isn’t the problem; the failed waterproofing layer underneath is.
- A musty smell that doesn’t leave, even after cleaning. Once water gets trapped between the tile and a failed membrane, the dark, warm cavity behind it never dries out fully in Houston’s climate. Mold follows within weeks.
- Floor tiles that flex or sound hollow when tapped. That’s a sign the mortar bed or backer board has absorbed water and lost its bond. By the time a tile flexes, the structural substrate is compromised.
- Water staining on the ceiling of the room below the bathroom. This means the pan liner or drain connection has failed completely and water is traveling through the floor assembly. This is an active leak, not a cosmetic issue.
- Caulk that pulls away from the tub edge or shower curb within months of re-caulking. Silicone caulk is a maintenance item, but if it’s separating from the surface repeatedly, the joint underneath is moving because the substrate is wet and swelling.

AfterReplacement Cost & What’s Included
For IKO-related bathroom work in Houston, here’s the pricing breakdown we give on the first call, and we honor it in writing before any work starts:
- Shower pan or water-damaged substrate repair: $3,000 – $8,500, including demolition, new waterproofing, mortar bed, and tile reset
- Tub-to-shower conversion with IKO-compatible waterproofing: $3,500 – $10,000
- Full IKO-compatible bathroom remodel: $9,000 – $28,000, depending on size, fixture selections, and whether we’re moving plumbing
- Small bathroom remodel with waterproofing replacement: $5,000 – $12,000
What drives the range is straightforward: the size of the wet area, how far the water damage has traveled into the framing, and the fixture tier you choose. A 5-by-8 bathroom with a standard tub surround lands on the lower end. A larger primary bath with a custom walk-in shower, heated floor, and curbless entry lands higher. Every Bradford Remodeling estimate is itemized so you see exactly where each dollar goes. And every completed project carries the 365-Day Done Right Promise in writing: if the repair or remodel fails within one year, Curtis Lane sends our crew back at no charge.
DIY or Call Us?
You can safely check a few things yourself: look for visible water staining, test whether floor tiles flex under pressure, and note where grout or caulk is failing. Those observations help us give you a tighter phone estimate. What you shouldn’t do is start removing tiles to “see how bad it is” underneath. Once you breach the waterproofing layer, you’ve turned a contained problem into an open one, and if there’s mold behind the tile, you’ve just released spores into your Houston home’s air without containment.
We’ve also seen homeowners try to patch a failed IKO membrane with liquid sealant from a big-box store. In our experience, that buys you a few months at best and makes the eventual repair more expensive because the patch material has to be ground off before the real waterproofing can be installed. If the membrane has failed, the fix is replacement, not coating. Call (940) 289-7658 and we’ll tell you straight what you’re looking at.
FAQs
An IKO membrane installed correctly over a properly sloped substrate typically lasts 10 to 15 years in the Houston market, though tile and grout maintenance affects that number. The membrane itself doesn’t degrade from exposure because it’s buried under tile; what kills it is movement in the substrate or installation errors at the seams and corners. Call (940) 289-7658 if you suspect a liner failure and we’ll assess it honestly before recommending any work.
In most cases, no. By the time a membrane failure is visible from inside the bathroom or on the ceiling below, the water has already compromised a larger area than you can see. Patching a buried membrane without exposing the full extent of the damage leaves the same failure pathway open. A full replacement of the waterproofing assembly is usually the only fix that carries a meaningful warranty, and it’s what we recommend when we quote the job.
Most shower pan or waterproofing replacements take 3 to 5 working days in Houston, which includes demolition, framing repair if needed, new waterproofing, tile installation, and a 24-hour water test before we close the walls. Full bathroom remodels run 2 to 4 weeks depending on scope. We give you a schedule in writing with the estimate, and we hold to it.
Yes, we keep common IKO-compatible sheet membranes, drain assemblies, and backer boards on our Houston trucks so most repair jobs can start without waiting on a supplier order. For full remodels, we order materials to your spec before we start. We also work with KraftMaid cabinetry, Cambria and Silestone surfaces, and Moen and Kohler fixtures, so whatever your IKO repair requires, the surrounding materials are documented and warrantied too.
