IKO Bathroom Remodeling: The Orlando Owner’s Guide
If you’re searching for IKO bathroom remodeling in Orlando, you likely have an IKO product that has failed or is nearing the end of its service life. We install IKO-compatible bathroom waterproofing, underlayment, and ventilation systems as part of full bathroom remodels in Orlando, with total project costs typically ranging from $9,000 to $28,000 depending on scope, materials, and the condition of what’s behind your walls. Most Orlando homeowners discover a problem the same way: a soft spot on the floor near the tub, peeling paint on the ceiling below an upstairs bathroom, or that persistent musty smell that never quite goes away.

We’re an independent Orlando remodeling contractor, not an IKO dealer or affiliate. What that means for you is straight talk about what’s failing, what it costs to fix, and whether the rest of your bathroom is worth saving. We also keep parts on hand for KraftMaid, Cambria, and Silestone products, so if your vanity, countertop, or shower surround is part of the same project, we can handle it in one visit.
Which IKO Models This Applies To

IKO manufactures a range of building products, and in Orlando bathrooms, the ones we see most often are their waterproofing membranes, underlayments, and ventilation components. The tricky part is that IKO’s product lines span different eras and specifications, and not all of them are still in production. If you have the original packaging or an invoice, look for a product code starting with “IKO” followed by a series identifier. If you don’t, measure the membrane thickness (most residential bathroom membranes run between 40 and 60 mil) and note whether it’s a peel-and-stick or hot-mop application.
Here’s the compatibility gotcha we run into constantly in Orlando: older IKO peel-and-stick membranes from the early 2000s have a different adhesive chemistry than current formulations. You can’t just patch a newer membrane over an older one and expect a watertight bond, especially in Orlando’s humidity where condensation cycles are aggressive year-round. For most failed IKO bathroom components, we recommend replacing the affected section entirely rather than patching, and we source OEM parts when available. If the original is discontinued, we specify a quality aftermarket equivalent that matches the thickness, permeability rating, and adhesive profile of what you had.

Signs Your IKO Bathroom Component Is Failing
- Soft or spongy spots on the bathroom floor. This usually means water has penetrated the membrane or underlayment and reached the subfloor. In Orlando’s humid climate, once moisture gets under the flooring, it doesn’t dry out on its own.
- Water stains or peeling paint on the ceiling below the bathroom. The waterproofing layer has failed somewhere and water is traveling along the joists. By the time you see ceiling damage, the leak has been active for weeks.
- A musty odor that returns within a day or two of cleaning. Mold and mildew are feeding on moisture trapped behind the walls or under the floor. This is common in Orlando homes where the bathroom fan doesn’t move enough air, causing condensation to accumulate.
- Grout that keeps cracking or falling out in the same area. Movement in the substrate (the layer beneath your tile) means the underlayment is compromised. Re-grouting won’t fix the underlying problem.
- Rust-colored staining around the toilet base, tub edge, or shower pan. The waterproofing membrane has torn or lifted, and water is contacting the metal lath or plumbing supports underneath.

AfterReplacement Cost & What’s Included

In Orlando, a full bathroom remodel with IKO-compatible waterproofing and underlayment replacement runs $9,000 to $28,000. A smaller bathroom or a straightforward tub-to-shower conversion lands on the lower end at $5,000 to $12,000. What drives the number up is what we find when we open the walls: if the water damage extends into the subfloor, the joists, or the studs, that’s additional framing and drying work before any new waterproofing goes in.
Every quote includes the parts, the labor, the waterproofing materials, and our written guarantee. You get the number in writing before we start, and the number on the invoice is the same number you approved. If the repair fails inside 365 days, we come back and fix it at no charge. That’s the Done Right Promise, and it’s written on every project we do in Orlando.
DIY or Call Us?
You can safely inspect a few things yourself: check whether your bathroom exhaust fan is actually moving air by holding a piece of toilet paper up to the grille while it runs. Check for visible cracks in the tile or tub surround. Check for soft spots by pressing firmly on the floor near the tub and toilet. These inspections won’t hurt anything, and they’ll help you describe the problem when you call.
What you should not attempt is removing tile, cutting into the subfloor, or peeling back the waterproofing membrane to “take a look.” Once that membrane is breached, you’ve turned a contained problem into an active leak. It also makes the eventual repair more expensive because we now have to replace a larger area. If you suspect an IKO component has failed in your Orlando bathroom, call us at (850) 427-6454 and we’ll come out for a free estimate. We’ll tell you what’s wrong, what it costs to fix, and whether you need a full remodel or a targeted repair.
FAQs

In Orlando’s climate, most IKO bathroom membranes and underlayments last 15 to 25 years, but the real lifespan depends on the bathroom’s ventilation and how much water actually pools on the surfaces. A poorly ventilated bathroom in a home on Lake Conway or in College Park with constant humidity can shorten that lifespan by a third. If your bathroom is over 15 years old and showing any of the warning signs above, it’s time for an inspection. Call (850) 427-6454 and we’ll give you an honest assessment.
Sometimes yes, if the failure is localized and the surrounding materials are still sound. We’ll replace just the affected membrane section, re-waterproof the seams, and retile over the repaired area. But if the water has been traveling for months, the damage usually extends farther than the visible signs suggest. We’ll show you what we found and give you a repair option and a replace option, both with written pricing. Call us at (850) 427-6454 for a free estimate and we’ll tell you what’s actually necessary.
A typical targeted repair takes one to two days. A full bathroom remodel in Orlando with new waterproofing, underlayment, tile, and fixtures takes two to four weeks depending on scope and permitting. We give you a defined arrival window and a written schedule before we start, so you’re not guessing when the crew shows up.
We carry commonly used IKO-compatible membranes, seam tapes, and ventilation components in our Orlando inventory, along with parts for KraftMaid, Cambria, and Silestone products. If your specific part is discontinued or unusual, we order it and let you know the timeline before we schedule. Call (850) 427-6454 and we’ll check availability while you’re on the phone.
