IKO Bathroom Remodeling Nationwide

IKO Bathroom Remodeling: The Miami Owner’s Guide

IKO bathroom remodeling in Miami typically runs $10,620-$33,040 for a full renovation, with smaller bath refreshes starting around $5,900. We stock IKO-compatible waterproofing membranes, underlayment systems, and vapor barrier components for same-day installation on most jobs. Most Miami homeowners discover their IKO system is failing when they spot bubbling vinyl flooring, soft spots near the tub, or a musty smell that returns after cleaning - all signs that moisture has breached the waterproofing layer beneath the surface.

Which IKO Models This Applies To

IKO’s Profor, EasyLay, and ArmourGard membrane series are the three lines we see most often in Miami bathrooms, particularly in homes built between 2005 and 2019 when IKO pushed hard into the Florida market after the hurricane seasons. The Profor line uses a 40-mil thickness with a dimpled drainage plane; EasyLay is the thinner 30-mil self-adhering option found in many condo renovations where weight and height matter; ArmourGard is the 60-mil commercial-grade membrane used in higher-end Coral Gables and Pinecrest installations.

To identify what you have, look for the stamped series name on the membrane edge where it meets the drain flange, or check for the IKO lot number on any leftover roll ends the previous contractor left behind. The lot number prefix - PF for Profor, EL for EasyLay, AG for ArmourGard - tells us exactly which adhesive, seam tape, and corner boots to bring. We source OEM IKO components where the system is still under warranty, but we’ve also vetted a Fort Lauderdale-based membrane manufacturer whose 40-mil product meets the same ASTM D4068 standard at a lower per-square-foot cost. The catch: mixing OEM and aftermarket membrane on the same wet-area floor voids any remaining IKO warranty, so we flag this upfront in writing before anyone cuts a roll.

Signs Your IKO Bathroom Remodeling Is Failing

• Soft or spongy flooring near the tub or shower. This means water has saturated the subfloor through a torn or poorly lapped membrane seam. In Miami’s humidity, plywood subfloor can lose structural integrity in as little as six weeks of continuous moisture exposure.
• Grout cracking in the same pattern repeatedly. When the membrane below loses adhesion and shifts, the tile layer above moves microscopically with each hot-water cycle. The grout fatigues and cracks along the stress lines, usually within 18 months of the original install.
• Musty odor that persists after deep cleaning. IKO’s self-adhering membranes can delaminate from the substrate when installed over OSB that wasn’t primed with the manufacturer’s specified latex primer. The trapped moisture breeds mold in the cavity where you can’t reach it.
• Tile popping or “drumming” when tapped. This happens when the thinset bed detaches from a membrane that has begun to plasticize from heat buildup. South-facing bathrooms in Miami with unshaded windows see this most, especially where dark tile absorbs afternoon sun.
• Water staining on the ceiling below the bathroom. By the time you see this, the membrane has failed at a penetration point - usually the toilet flange, shower drain, or valve escutcheon - and water has found a path through the stack or joist bay.

Replacement Cost & What’s Included

The spread within each range comes down to three things: how far the moisture traveled before it was caught, whether the subfloor needs replacement (add $1,200-$3,800 in Miami’s current lumber market), and the finish grade you select. We quote every job with a written line-item scope before work starts - Clause 1 of the Haven Standard - and no change proceeds without a signed change order. The 365-Day Done Right Promise covers the waterproofing workmanship; membrane material defects fall to the manufacturer’s warranty, which we register for you.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can verify the lot number, photograph the failure pattern, and check for obvious membrane gaps at drain penetrations - all useful diagnostic steps that save us time on arrival. What we don’t recommend is cutting into a bonded membrane or attempting a partial replacement. IKO’s self-adhering products require a specific primer and roller pressure that most homeowners don’t have on hand, and the seam overlaps must hit exact inch-and-a-half minimums or the warranty is void. Worse, Miami’s building code requires flood testing of shower pans for 24 hours before tile goes back; skip this and you’re liable for the next failure.

We’ve rebuilt three bathrooms in the past two years where the homeowner’s DIY membrane patch held for four to eight months, then let go catastrophically during a holiday weekend. The second repair always costs more because the moisture has traveled further. If you’re unsure, call us at (786) 321-4970 - we’ll look at it, photograph what we find, and give you a written price before you decide.
