IKO Bathroom Remodeling: The Tampa Owner’s Guide
A full IKO bathroom remodel in Tampa typically runs $9,000 – $28,000 installed, depending on the size of the wet area, what’s behind the walls, and whether you’re moving plumbing. Most jobs take 2 – 4 weeks from demo to signed close-out. Homeowners usually call us after a shower pan cracks, tile starts popping off the substrate, or water stains appear on the ceiling below a second-floor bath and they realize the problem isn’t cosmetic, it’s structural.
We’re an independent Tampa contractor that installs IKO-compatible bathroom systems. We’re not affiliated with IKO, but we know their product lines well enough to order the right membrane, pan, and board the first time, which saves you the cost of a wrong part and a second trip charge.
Which IKO Models This Applies To
IKO makes waterproofing membranes and underlayments that go under tile in showers, tub surrounds, and bathroom floors. The most common lines we work with in Tampa are the IKO Shield and IKO AquaBarrier families, but older homes in Seminole Heights and Carrollwood sometimes have discontinued rolls that were installed a decade ago and need matching by spec rather than by label.
Here’s the compatibility gotcha: IKO membrane thickness varies from 8 mil to 40 mil depending on the application, and you cannot swap a floor-grade product onto a shower wall and expect it to hold. We measure the existing membrane with a micrometer before ordering the replacement. If the label is gone or unreadable, the thickness plus the substrate type tells us which current IKO product is the correct match.
OEM versus aftermarket: for IKO waterproofing, we use OEM when the original membrane is still sold and within spec. When a product line has been discontinued, we use a documented compatible membrane from a brand we already stock, like the Cambria or Silestone installation systems we carry on our trucks. Tampa’s humidity makes this decision more important than it would be in a drier climate: a cheap aftermarket membrane that meets code in Phoenix may not hold up under a Tampa shower that runs hot and steamy ten times a day.
Styles & brands we work with
Signs Your IKO Bathroom Remodeling Is Failing
- Water stains on the ceiling below the bathroom. The membrane under the tile has breached somewhere. By the time the stain shows, the subfloor under the shower is already wet and the damage is spreading outward.
- Loose or hollow-sounding tiles. Water has gotten between the tile and the substrate and dissolved the thinset bond. If you tap a tile and it sounds like a knock on a hollow door, the waterproofing behind it is compromised.
- Musty odor that doesn’t go away. Mold is growing inside the wall cavity or under the floor. Tampa’s heat and humidity accelerate this once moisture is trapped, and bleach on the surface won’t reach the source.
- Grout lines cracking repeatedly. This usually means the substrate is flexing. A properly waterproofed IKO system doesn’t flex enough to crack grout, so repeated cracks point to movement underneath, often from a rotted subfloor or shifting framing.
- Water pooling in corners of the shower. The pan slope has settled or the membrane has delaminated at the seam. Water that doesn’t drain in under ten minutes is slowly working its way through whatever barrier was supposed to stop it.

AfterReplacement Cost & What’s Included
A full IKO bathroom remodel in Tampa runs $9,000 – $28,000. A smaller project, like replacing a fiberglass tub with a tile shower on an IKO membrane, typically falls in the $4,500 – $12,000 range depending on tile choice and whether the valve needs moving.
| Scope | Typical Tampa Range |
|---|---|
| Full bathroom remodel with IKO waterproofing | $9,000 – $28,000 |
| Small bathroom remodel | $5,000 – $12,000 |
| Walk-in shower installation | $4,500 – $12,000 |
| Tub-to-shower conversion | $3,500 – $10,000 |
| Shower replacement | $3,000 – $8,500 |
What drives the range: whether we’re pulling the old pan and replumbing the drain, what condition the studs and subfloor are in once the tile comes off, and the tile and fixture selections. We give you a written price before any work starts, and that number doesn’t move at the door. Every job is covered by the 365-Day Done Right Promise: if the work fails inside the first year, we come back and correct it at no charge.
DIY or Call Us?
You can safely check a few things yourself: 1) run water in the shower for ten minutes and watch where it pools, 2) tap tiles across the wet area and listen for hollow spots, 3) inspect the grout and caulk lines with a flashlight. None of that requires tools or any risk.
What you shouldn’t do is pull up tiles or cut into the membrane to find the leak. Water damage behind a shower wall is never as small as it looks from the outside. If the waterproofing has failed, the standard fix is to remove everything down to the studs, repair or replace the substrate, install a new IKO membrane, and retile. That’s not a weekend project, and a half-fixed membrane will just leak again behind new tile. Call us at (941) 655-9297 and we’ll look at it before you spend money on guesses.
FAQs
A properly installed IKO membrane should last 15 – 25 years in Tampa, but the real world answer is that the tile above it usually fails first. Humidity and daily steam cycles shorten the lifespan of the adhesive bonds, even when the membrane itself is intact. Call (941) 655-9297 for a free estimate on a replacement.
Small seam failures can sometimes be patched if caught early, but by the time water is visible on a ceiling or tiles are popping, the substrate underneath is already wet and the repair has to go back to the studs. We always give you an honest assessment based on what we actually find, not what’s convenient to sell.
A straightforward tub-to-shower conversion or shower replacement in Tampa is usually done in 5 – 10 working days. A full bathroom remodel with moved plumbing, custom tile, and new vanity installation takes 2 – 4 weeks. The written price you sign includes the schedule, so you know the timeline before demo starts.
We keep common IKO membrane sizes in stock for standard shower pans and tub surrounds. If your project needs a specific thickness or a discontinued line matched by spec, we order it on day one so it’s on site by the time the substrate work begins. We also carry Cambria and Silestone installation materials for vanity and countertop work, so most parts arrive with the crew rather than after the project starts.
Straight number, clear scope, no surprises at close-out. Call us at (941) 655-9297 to schedule your free estimate in Tampa.
