IKO Bathroom Remodeling: The Tampa Owner’s Guide
We install full bathroom remodels in Tampa using IKO-compatible building products, with complete project pricing typically ranging from $9,000 to $28,000 depending on square footage, fixture selection, and whether walls or plumbing move. Most IKO-related bathroom failures we see aren’t the IKO product itself, but what happens around it: moisture breaching a seam, a waterproofing layer that was skipped by the original installer, or a shower pan that was never sloped correctly. Homeowners usually discover the problem as a soft spot under tile, a persistent musty smell, or grout that stays dark long after the shower dried.
Graham Stein has walked enough Tampa bathrooms to know where these failures hide. He writes it down before we start so nobody is guessing mid-project, and the crew keeps the floor protected while we tear out what failed.
Which IKO Models This Applies To
IKO makes a range of roofing and waterproofing products, and in bathroom remodeling the relevant lines are their waterproofing membranes and underlayments used under tile in wet areas. The compatibility question is less about “which IKO model number on the label” and more about what sits beneath your tile: an IKO waterproofing membrane, a competitor’s membrane, or in older Tampa homes, no membrane at all. Homes built before the mid-1990s in Seminole Heights, Tampa Heights, and Riverside Heights often have tile set directly on a mud bed with no waterproofing layer behind it. That’s the original construction method, not an IKO failure.
If you have IKO waterproofing already installed, the part that matters is the membrane itself and its compatibility with the type of thin-set mortar and grout used above it. IKO membranes are designed for either modified or unmodified thin-set depending on the product line, and using the wrong one voids the system. A quality aftermarket membrane from Schluter or a comparable brand is what we would use if you’re replacing a failed waterproofing layer, because the warranties are independent and verifiable. We are an independent remodeling contractor, not affiliated with IKO, so we match the right product to your specific shower or tub surround rather than defaulting to a single brand.
Styles & brands we work with
Signs Your IKO Bathroom Remodeling Is Failing
- Grout that stays dark after drying. Water has gotten behind the tile and the grout is wicking it back out. The waterproofing layer beneath has likely been compromised, or was never present.
- Tiles that sound hollow when tapped. The mortar bond has broken down, usually from water penetration or movement in the substrate. A hollow-sounding tile is a tile that’s about to come loose.
- A musty smell that returns within hours of cleaning. Mold and mildew are growing in the wall cavity or under the shower pan, which means water is pooling where it should never be.
- Soft or sagging spots in the floor around the toilet or tub. The subfloor is rotting. This is the most expensive fix, because the rot usually extends farther than the soft spot suggests once we open it up.
- Efflorescence or mineral staining on lower wall tiles. Water is migrating through the wall assembly and evaporating on the surface, leaving mineral deposits behind. The waterproofing layer is no longer doing its job.

AfterReplacement Cost & What’s Included
A full bathroom remodel in Tampa runs $9,000 to $28,000 with Elmstead Remodeling Tampa. Smaller refreshes and partial fixes fall lower: a tub-to-shower conversion ranges $3,500 to $10,000, a shower replacement $3,000 to $8,500, and a walk-in shower installation $4,500 to $12,000. What drives the range is whether we’re keeping the existing layout or moving plumbing fixtures, whether the subfloor needs replacement, and the fixture brands you choose.
Every quote includes the written price before any work starts, the waterproofing system by name, the tile and grout spec, and a line-item breakdown of materials and labor. Our 365-Day Done Right Promise covers every completed project: if it’s not done right, we make it right. We stock KraftMaid, Cambria, and Silestone products alongside IKO-compatible materials, so we can show you named-brand options during the estimate rather than a vague “premium materials” line.
In Tampa’s humidity, we always specify a full waterproofing membrane behind the tile, even if the original bathroom never had one. That’s a spec decision that costs more upfront but prevents the exact failure you’re probably dealing with right now.
DIY or Call Us?
You can safely check for visible damage: run your hand along grout lines for crumbling, tap tiles to find hollow spots, and look for staining around the shower base and toilet flange. Those observations help us diagnose faster. What you should not do is pull tiles off a shower wall to “look behind them.” If the waterproofing is intact, you’ve just punctured it. If it’s not intact, you’re exposing yourself to whatever mold is growing inside the wall cavity. Disturbing black mold without containment spreads spores through the house.
Wet-area remodeling also involves plumbing work that requires a permit in the city of Tampa, and pulling a shower without a permit can come up when you sell the home. We pull permits, pass inspections, and keep a photo record of what’s behind the walls before we close them back up. If you’re not sure whether your bathroom needs a full remodel or a targeted repair, call (850) 779-4017 and describe what you’re seeing. We’ll tell you straight what’s worth fixing and what’s worth replacing.
FAQs
An IKO waterproofing membrane properly installed behind tile should last the life of the bathroom itself, easily 20 to 30 years or more. What fails in Tampa bathrooms is usually the installation around seams, corners, and penetrations, or the surrounding materials – grout, caulk, and tile – that allow water to find another path. The Florida climate’s humidity accelerates any small leak because materials dry slowly, which is why we specify full waterproofing coverage and inspect every seam before closing a wall. Call (850) 779-4017 and we’ll evaluate whether your membrane is still doing its job.
In most cases, no. Waterproofing works as a continuous sheet, and a breach in one spot means water has already migrated behind it elsewhere. Spot repairs fail because the new membrane can’t seal to the old one reliably at the seam. The honest fix is removing tile down to the studs or substrate, installing a continuous new waterproofing system, and re-tiling. It’s more work up front, but it’s the only way to guarantee the leak doesn’t return. Graham writes the fixed price down before that work begins – call (850) 779-4017 for the exact number.
A full gut-and-remodel bathroom in Tampa typically takes 3 to 5 weeks with Elmstead Remodeling Tampa, depending on whether plumbing is moving and how much subfloor needs replacing. A tub-to-shower conversion or shower replacement is faster, usually 1 to 2 weeks. We’ll give you a written schedule with the estimate, and we keep noise confined to the hours we told you to expect it. Call (850) 779-4017 to get a timeline for your specific bathroom.
We stock the standard waterproofing membranes, seam tapes, corner pieces, and thin-sets we use most often on Tampa bathroom jobs, so the crew arrives ready to start waterproofing day one if that’s where the project is. If your bathroom needs a specific IKO product line or a special-order membrane, we order it before the job starts so there’s no delay mid-project. Every product gets named in your written quote before we begin. Call (850) 779-4017 and tell us what you have installed now, and we’ll tell you what we’d put back.
We use drop cloths on the floors and shoe covers at the door on every job. Before we start tearing anything out, we’ll tell you exactly what we’re doing, what it costs, and what the crew will do to keep the rest of your Tampa home clean. Call (850) 779-4017 to schedule your free estimate, and we’ll show you the written price before a single tool comes off the truck.
