IKO Bathroom Remodeling: The Fort Lauderdale Owner’s Guide
IKO bathroom remodeling in Fort Lauderdale typically runs $9,000-$28,000 for a full replacement, and we stock IKO-compatible waterproofing membranes, underlayment, and flashing components for same-day starts on most jobs. Most owners first realize something’s wrong when they spot water staining on a ceiling below the bathroom, or when tile grout starts crumbling despite no visible leak - signs that the IKO membrane or drainage plane has failed behind the finish materials.
Which IKO Models This Applies To
IKO doesn’t manufacture finished bathroom fixtures like vanities or tubs. What we install are IKO’s waterproofing and drainage products: Proforment SBS-modified bitumen membranes, IKO Shield ice and water protector (repurposed for wet-area secondary containment), and IKO Armourvent ridge vent components adapted for bathroom exhaust integration. The critical match is membrane thickness - Proforment comes in 2.0mm and 3.5mm grades, and Fort Lauderdale’s humidity demands the thicker spec for steam-shower enclosures.
To identify what you’ve got, check the membrane roll edge for the IKO diamond logo and thickness stamp. If your bathroom was remodeled between 2015 and 2020, there’s a good chance the contractor used IKO Shield as a pan liner substitute - it’s SBS-modified and flexible, but not technically rated for continuous submersion. For OEM-strict warranty coverage, we source direct from IKO’s Tampa distribution center. When the job doesn’t require OEM documentation for a home sale, we also install equivalent SBS membranes from Polyglass and CertainTeed, both held to the same 3.5mm spec. Rowan Construction Group Fort Lauderdale is an independent service provider, not affiliated with IKO.
Signs Your IKO Bathroom Remodeling Is Failing

- Water stains on the ceiling directly below the bathroom. This means the IKO membrane has developed a breach at a seam or penetration, letting shower water reach the subfloor. In Fort Lauderdale, the constant AC cycling between 72°F and 78°F expands and contracts the membrane faster than in drier climates.
- Tile grout cracking in straight lines along the shower base perimeter. The pan liner or membrane has shifted or delaminated, allowing minor flex in the substrate. Grout doesn’t stretch; it telegraphs movement.
- Musty odor that returns within 48 hours of cleaning. Organic growth behind tile indicates chronic moisture behind the waterproofing layer. IKO’s bitumen membranes resist biological attack, but the paper facer on some grades can support mold if the edge seal fails.
- Soft spots in the bathroom floor near the toilet or tub. The subfloor has taken water. Often this traces to failed wax ring or tub flange seal, but if the IKO membrane wasn’t lapped correctly at these penetrations, water tracks laterally instead of draining to the weep holes.
- Exhaust fan dripping water or running constantly. Poor vapor drive management. IKO Armourvent, when used as part of a balanced ventilation strategy, should move humid air out before it condenses in the duct. If the vent path is blocked or undersized, moisture loads the membrane from the interior side.

What drives the range: bathroom size, whether we’re removing a cast-iron tub (heavier, more labor), the condition of the subfloor once tile comes up, and whether Fort Lauderdale’s 25-year-old galvanized supply lines need replacement while walls are open. Every quote from Rowan Construction Group Fort Lauderdale is a flat written price with line-item material brands listed - IKO, KraftMaid, Cambria, Silestone - before any work starts, per Clause 1 of The Haven Standard. The 365-Day Done Right Promise covers installation labor and membrane adhesion. No change proceeds without a signed change order, which is why our projects finish within a few percent of the number you agreed to.
DIY or Call Us?

There’s a short list an owner can safely check: confirm the exhaust fan duct isn’t blocked, verify the shower door sweep seals, and look for obvious grout gaps. Beyond that, bathroom waterproofing carries real risk. SBS membrane application requires a propane torch for heat-welding seams, and the fumes in an enclosed Fort Lauderdale bathroom with no window are hazardous. More critically, if you remove tile and find the subfloor compromised, you’ve opened a structural repair that needs permitting. We pull permits and schedule inspections as part of our standard scope - not an add-on. Call (754) 254-7676 and we’ll scope it, photograph what we find, and put the price in writing before anyone picks up a tool.
FAQs
Properly installed IKO Proforment membrane should last 20-30 years, but Fort Lauderdale’s salt air and year-round humidity can accelerate adhesive degradation at seams. We inspect membrane edges and penetrations as part of our documented photo record. Call (754) 254-7676 for an exact quote - estimates are free.
Patching works only for isolated punctures smaller than a quarter, and only if the surrounding membrane is fully adhered. Most failures we see in Fort Lauderdale are seam delamination or multiple penetration breaches, which means full replacement. We’ll show you the photo evidence and quote both scenarios if possible.
Typical timeline is 10-14 working days for a standard 5×8 bathroom, assuming no subfloor replacement or plumbing relocation. Demolition and membrane installation take 3-4 days; tile and fixture finish takes the balance. We provide a written schedule with the quote, not after.
We stock IKO Proforment 3.5mm membrane, Shield ice and water protector, and compatible seam primer on every bathroom remodeling truck. Specialty flashings and custom shower pan configurations we pull from Tampa with 24-hour lead time. Measure twice, write it down, then say it once - that’s how we avoid a mid-job parts run that costs you a day.
