IKO Bathroom Remodeling: The Dallas Owner’s Guide
If you have an IKO-branded bathroom in your Dallas home and something’s failed, we can help. A full IKO bathroom remodel in Dallas typically runs $9,000 – $28,000 depending on the size of the space, what’s behind the walls, and the materials you choose. Most owners discover a problem when tile starts pulling away from the wall, the shower pan flexes, or water stains appear on the ceiling below a second-floor bath. We’ll walk you through what to look for, what it costs, and what the fix actually involves.
Key takeaways: IKO is primarily known for roofing and waterproofing products, so when we talk about “IKO bathroom remodeling” in Dallas, we’re usually dealing with IKO waterproofing membranes, underlayment, or sealants that were installed as part of a bathroom system. We order these parts directly and install them to manufacturer spec. Penhallow Remodeling Dallas is an independent general contractor, not affiliated with IKO, but we work with their product lines regularly in bath tear-outs and rebuilds across Dallas neighborhoods.
Which IKO Models This Applies To

IKO makes a range of waterproofing and underlayment products that end up in Dallas bathrooms, often as the moisture barrier under tile or behind shower surrounds. The most common ones we see in Dallas homes are the ArmourGard and StormShield lines used as shower pan liners and behind-wall moisture barriers, plus AquaBarrier self-adhered flashing at tub surrounds. If you’re not sure which IKO product you have, look for the printed label on the membrane edge behind the tile or under the shower pan liner. The label will show the product name and roll code, which tells you exactly which version you’re dealing with.
Here’s the compatibility gotcha most Dallas homeowners run into: IKO shower pan liners are not interchangeable across all their product lines. A StormShield liner is a 40-mil composite sheet designed to be clamped into a drain assembly, while AquaBarrier is a thinner peel-and-stick flashing meant for vertical surfaces and corners. Using the wrong one under a new tile pan is how you get a shower that leaks into the subfloor six months after the remodel is done. When we open a Dallas bathroom wall and find a failing IKO membrane, we always check the product label before ordering a replacement. OEM IKO parts are our default for warranty continuity. Quality aftermarket equivalents only make sense when the original product is discontinued, and even then we verify the thickness, permeability rating, and drain compatibility before we’ll install it.

Signs Your IKO Bathroom Remodeling Is Failing
- Shower floor feels soft or spongy underfoot. This almost always means water got past the IKO pan liner and is soaking the subfloor. In Dallas, where we get big temperature and humidity swings, that trapped moisture starts breaking down plywood and OSB faster than you’d expect.
- Tile cracks along the shower floor or lower wall joints. When the substrate under the tile swells from water exposure, the tile has nowhere to go. Hairline cracks along the pan-to-wall transition are a classic sign the waterproofing layer failed first.
- Water stains on the ceiling below a second-floor bathroom. We see this regularly in Lakewood and East Dallas homes with older bathrooms. The IKO membrane under the shower pan develops a tear at the drain clamp or a corner fold, and water finds the path of least resistance down through the joists.
- Musty smell that won’t go away, even after cleaning. Trapped moisture behind tile grows mold in the stud cavities. If you’ve scrubbed every surface and the smell still comes back, the problem is behind the wall, not on it.
- Grout that stays dark or wet long after a shower. Grout is porous, but if patches stay damp for days, water is wicking from behind the tile. That points to the IKO barrier failing at a seam or corner detail.

AfterReplacement Cost & What’s Included

A bathroom remodel in Dallas involving IKO waterproofing replacement typically runs $9,000 – $28,000. At the lower end, you’re looking at a small bathroom where we remove the shower pan, replace the failed IKO liner, retile the floor, and reuse the existing vanity and fixtures. At $28,000, you’re doing a full tear-out and rebuild of a larger primary bath: new IKO waterproofing throughout, new tile or stone, new glass, new fixtures, and structural repair to any framing that got water-damaged.
What moves the number: the size of the shower footprint, whether we’re pulling the entire bathroom floor or just the wet zone, the tile you choose, and whether framing rot needs to be cut out and sistered. Every quote we give in Dallas is a written, line-item price before work starts. That price includes parts, labor, demolition, disposal, and the 365-Day Done Right Promise in writing. If the IKO membrane leaks inside that year, we come back and fix it at no charge. No service call fee, no re-inspection fee, nothing.
DIY or Call Us?
Here’s the honest split. You can safely check for a few things yourself: run your hand along the shower floor edges and look for tile movement, check the ceiling below for stains, and peek behind the escutcheon plate at the shower valve to see if the substrate looks dark or crumbly. That tells you there’s a problem. What you shouldn’t attempt is pulling the shower pan or removing tile to get at the IKO membrane yourself. The waterproofing layer under a shower pan is a single continuous sheet running up the walls and clamped into the drain assembly. If you nick it or seat it wrong, you’ve got a leak you won’t see until the subfloor fails underneath. And in a Dallas summer, that trapped moisture turns a small repair into mold remediation and structural work in a matter of weeks.
Trevor Nash has been opening up wet bathrooms for long enough to say this plainly: give you a number before I pick up a tool, that’s the only way we know how to start. Call (940) 204-5368 and we’ll come out, diagnose what actually failed, and hand you a written price.
FAQs

An IKO shower pan liner or behind-wall membrane should last 20 – 30 years when installed correctly, but the failure point is almost always the seams, corners, and drain clamp, not the sheet itself. In Dallas, where foundations shift with clay soil movement, corner stress on waterproofing is a real thing. If your bathroom is 15+ years old and showing any of the signs above, the membrane is the first thing we check.
Not safely, no. Once water has been getting through the membrane, the subfloor under it is compromised. Patching a torn pan liner without pulling the tile means you can’t see or fix the water damage underneath, and the patch itself becomes the next failure point. Proper repair means removing the tile and the top mortar bed, replacing the IKO liner with a new one, and rebuilding the pan. Call (940) 204-5368 and we’ll tell you exactly what your bathroom needs after we see it in person.
Most IKO pan liner replacements and small bathroom rebuilds take 5 – 10 working days start to finish. That includes demolition, subfloor repair, new waterproofing, a 24-hour flood test on the pan, tile work, and grout cure time. A full primary bathroom remodel runs 3 – 6 weeks depending on scope and material lead times. We give you a written schedule with the price, and we finish on the schedule we quote.
We keep IKO AquaBarrier, StormShield pan liner, and the matching corner and drain details on our Dallas trucks for most service calls. If you have a less common IKO product or an older discontinued version, we order the exact replacement and schedule the work once it’s in hand. We’ll never start a tear-out and leave you waiting on a part. Call (940) 204-5368 and we’ll verify part availability before we touch a wall.
