IKO Bathroom Remodeling: The Jacksonville Owner’s Guide
IKO bathroom remodeling in Jacksonville typically runs $9,000 – $28,000 installed, depending on the scope, the condition of the substrate behind your existing walls, and whether you’re doing a full gut-out or a surface-level refresh. We stock IKO-compatible parts and work with IKO specifications on waterproofing and finishing systems regularly across Jacksonville. A failing IKO bathroom usually announces itself the same way every time: you’ll see discoloration at the base of the shower, a musty smell that won’t leave, or grout that keeps cracking no matter how many times you patch it.
If you’ve got an IKO-labeled bathroom system and a part has failed, you’re not chasing a mystery. You’re chasing water, movement, or a bad seal. Those are knowable problems. The trick is finding a crew in Jacksonville that will match the failing part to your IKO setup without guessing.
Key Takeaways:
- IKO bathroom remodels in Jacksonville range from $9,000 for a small, contained update to $28,000 for a full wet-area rebuild.
- The most common IKO-related failures we see in Jacksonville are waterproofing breaches at the shower pan and curb, not the visible tile or fixtures.
- Every Bradford Remodeling job gets a written price before work starts and is covered by the 365-Day Done Right Promise.
Which IKO Models This Applies To
IKO is known in the building trade for a few different product families, and the compatibility question changes depending on which one is behind your bathroom walls. The main IKO systems that show up in Jacksonville bathrooms are their waterproofing membranes, peel-and-stick flashing and underlayment products, and their roofing-to-wall transition materials that occasionally get extended into bathroom additions or second-story remodels. If your IKO part is a waterproofing layer, the spec that matters is thickness, typically 25 mil or 40 mil depending on the application, and how it was terminated at the corners and floor penetrations.
Identifying the right part starts with two things: the label still stuck on the material where it was cut, and the measurements of the failed area. If the label is gone, we match by thickness and by what the substrate looks like where the failure happened. For a Jacksonville homeowner, the practical question is usually not “which IKO part do I order online” but “which compatible material gets installed correctly with the right transitions and seams.” That’s where OEM versus quality aftermarket matters. For IKO waterproofing specifically, any substitute has to be approved for the same continuous-use wet environment and installed with the same overlap and sealant schedule. We make that call on-site, in writing, before we cut anything.

Signs Your IKO Bathroom Remodeling Is Failing
- Persistent musty odor that doesn’t clear with cleaning. This is trapped moisture behind or under a flooring layer. In Jacksonville’s humidity, once moisture gets behind a waterproofing layer, it stays there and starts working on the substrate. The smell is mold or mildew feeding on framing or cement board.
- Baseboard swelling, staining, or pulling away at the shower or tub line. Water is wicking outward past the waterproofing termination. It often means the IKO membrane wasn’t wrapped high enough at the wall-to-floor junction or the sealant bond has failed.
- Grout cracking repeatedly in the same joints. The surface is moving. That movement transfers stress through the tile assembly, and the grout is the first thing to fail. It’s rarely a grout problem; it’s a substrate deflection or a failed bond issue.
- Loose or hollow-sounding tiles near the drain or in the corner. The bonding layer has let go, and water has gotten between the tile and the membrane. Once tiles ring hollow, the top layer is dead; the real question is whether the membrane below held or not.
- Dark staining at the shower curb ends or the outside of the threshold. The curb is where waterproofing failures show first. Water that gets past the curb membrane will travel sideways. You’ll see the stain outside the shower before you ever see it inside.

AfterReplacement Cost & What’s Included
Plan on $9,000 to $28,000 for an IKO bathroom remodel in Jacksonville. On the low end, $5,000 – $12,000 covers a small bathroom that doesn’t need the wet area rebuilt or the plumbing moved. A full bathroom replacement, when you’re tearing out to the studs, repairing or replacing the substrate, waterproofing with an IKO-compatible membrane, and setting new surfaces, runs the upper end of that range. Here’s the line-item reality:
- Small bathroom remodel: $5,000 – $12,000
- Full bathroom remodel (this page’s lead range): $9,000 – $28,000
- Walk-in shower installation: $4,500 – $12,000
- Shower replacement: $3,000 – $8,500
- Bathroom vanity installation: $800 – $3,000
What you get from us is a written line-item price before the first tool comes out. That number includes demolition, disposal, substrate repair, waterproofing, materials, and installation labor. If we find hidden damage after demo, we stop and bring you a written revision before we spend another dollar. The job isn’t done until a clean site exists, the scope is documented, and you’re holding the signed 365-Day Done Right Promise in your hand. If anything fails within that year, we come back and fix it at no charge.

What you can safely check on your own: look for standing water after a shower, check whether the drain is running slow, and run your hand along the grout to find cracked or missing sections. You can also check whether the caulk at the wall-floor joint is pulling away. These diagnostics costs nothing and tell us a lot.
What you should not do is pull tile off a wet area thinking you’ll find the leak. Once you break the surface, you’ve committed to a repair, and if the waterproofing below is compromised, the only correct fix is a full rebuild to the existing IKO spec. We’ve seen Jacksonville homeowners spend a weekend and several hundred dollars on patch material, only to bring us in two months later because the leak never stopped. Water travels. The patch you put where you saw the stain is rarely where the water entered.
If you’re not sure whether the part can be saved, call us before you touch it. A quick look at photos or a short visit can save you a lot of wasted work. (904) 337-5929.
FAQs
A properly installed IKO-compatible waterproofing assembly in a Jacksonville bathroom typically lasts 15 to 25 years before the membrane, sealants, or underlying substrate need attention. Jacksonville’s humidity and the moisture load in a daily-use shower shorten the practical lifespan, especially if the original installation cut corners at the corners and transitions. Call (904) 337-5929 and we’ll tell you honestly whether your system has life left or needs replacement.
Sometimes a sealant joint can be re-done or a single tile replaced, but once water gets behind the waterproofing in a Jacksonville bathroom, a patch is a temporary measure. The correct repair almost always means opening the assembly, drying or replacing the substrate, and re-doing the waterproofing correctly to the IKO-compatible standard. Call (904) 337-5929 for a straight answer on your specific failure.
A small IKO-compatible bathroom replacement in Jacksonville typically takes 5 to 10 working days once we start. A full wet-area rebuild with substrate replacement runs 2 to 4 weeks. We give you a written schedule with the written price, and the scope gets locked before work begins.
