IKO Bathroom Remodeling: The West Palm Beach Owner’s Guide

IKO bathroom remodeling in West Palm Beach typically runs $9,000-$28,000 for a full replacement, and we stock IKO-compatible membranes, underlayment, and waterproofing components for same-day starts on most jobs. Most homeowners realize something’s wrong when they spot water staining on the ceiling below the bathroom, or when the tile surface feels spongy underfoot. In our experience along Flagler Drive and throughout the El Cid neighborhood, Florida’s salt air and summer humidity accelerate membrane failure in bathrooms that were built with IKO systems during the 2010-2018 construction wave.

Which IKO Models This Applies To

IKO doesn’t manufacture bathroom-specific product lines under its own name, but its IKO AquaBarrier and IKO ProFORMA waterproofing membranes were widely specified by West Palm Beach builders from 2012 through 2019, often paired with IKO GoldSeam seam tape and DuraBase cementitious underlayment boards. The compatibility issue we see most: homeowners buy a generic membrane that matches the square footage but miss the mil thickness spec. IKO AquaBarrier came in 40-mil and 60-mil versions, and the drain flange detail changes between them. Check the printed roll label, usually found on the back side of the vanity wall or behind the toilet flange access panel. The label shows the IKO part number, roll date, and mil rating.

OEM IKO membrane is still available through regional distributors in Miami-Dade, though lead times run 10-14 days. We stock a vetted aftermarket equivalent, NobleSeal TS, that matches the 60-mil thickness and passes the same ASTM D4068 puncture test, at roughly 15% less cost. For the IKO GoldSeam tape, we use the original, because the adhesive formulation on generic seam tapes breaks down faster in Florida’s humidity cycle.

Signs Your IKO Bathroom Remodeling Is Failing

• Soft spots near the toilet or tub. The IKO membrane beneath the tile has developed a breach, usually at a seam or drain flange, letting water saturate the cement board. In West Palm Beach, we see this most in bathrooms with south-facing windows where afternoon heat builds and accelerates adhesive fatigue.
• Grout cracking in a straight line pattern. This tracks the underlying seam in the IKO membrane or the cement board joints. The substrate is moving because moisture has compromised the bond, not because the tile itself failed.
• Musty odor that returns after cleaning. Water is trapped between the tile and membrane with no drainage path, a condition called a wet bed. IKO systems rely on proper weep holes at the drain, and these clog with construction debris or hard water deposits.
• Paint bubbling on the ceiling directly below. The membrane has failed at a penetration, typically the toilet flange or tub overflow, and water is following the joist bay. We’ve traced this to IKO installations where the plumber cut the membrane during rough-in and patched it with the wrong tape.
• Tile tenting or popping loose. The IKO DuraBase underlayment has absorbed moisture and expanded, breaking the thinset bond. This happens when the membrane fails first, or when the original installer used standard drywall instead of cement board in a wet area.

Replacement Cost & What’s Included

The spread on a full remodel comes down to three things: how much of the IKO system needs removal (a gut to studs adds $2,000-$4,000), whether we find subfloor rot in the joist bays, and the finish level you choose for tile and fixtures. Every quote we write in West Palm Beach includes the membrane, underlayment, thinset, grout, and a written 365-Day Done Right Promise on the waterproofing assembly. No change to that scope happens without a signed change order, per Clause 1 of The Haven Standard.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can pull a loose tile, look for staining on the cement board, and check whether the drain flange is seated properly, these are visual checks that tell you if water is getting past the surface. What you should not attempt is membrane replacement. The IKO system requires a continuous, factory-lapped seam with proper overlap at corners and penetrations, and the drain flange must be set to exact height before the mud bed cures. Get it wrong and you’re looking at a second gut six months later when the leak shows up downstairs. We carry the 60-mil membrane, the correct seam tape, and the drain assemblies on our truck, and we document every layer with photos before we cover it.
