IKO Bathroom Remodeling: The Jacksonville Owner’s Guide
IKO bathroom remodeling in Jacksonville typically runs $9,000 – $28,000 installed, depending on scope, materials, and how much of the existing waterproofing needs to come out before new work goes in. We stock IKO-compatible waterproofing membranes, drain assemblies, and substrate panels for most IKO shower systems, and we can usually schedule a Jacksonville install within two to three weeks of the written estimate. Most owners discover an IKO failure the same way: a soft spot in the shower floor, water staining on the ceiling below, or grout that never stays dry no matter how many times it’s resealed.
The truth about IKO products in Jacksonville is that the Florida humidity and the way older Jacksonville homes settle create specific stress points. What failed in a Sacramento renovation will not fail the same way in a Riverside bungalow. Graham Stein and our crews have spent the past several years replacing IKO bathroom systems across Jacksonville, including Avondale Craftsman homes where the original subfloor had to be sistered before any new waterproofing could go down. We name the material, name the day, name the price, so there is nothing left to wonder about.
Which IKO Models This Applies To
IKO manufactures several shower waterproofing lines, and the compatibility gotcha is this: IKO shower pans from the ShingleMatch line and the AquaBarrier series use different drain throat heights, so a replacement drain must match the pan depth, not just the brand. We measure the throat collar and the pan slope on site before ordering anything, because an off-the-shelf drain that’s 3/8″ too tall means the tile bed sits proud of the bathroom floor and water pools at the curb. That measurement is one of the things we document in the written estimate, so there’s no change order surprise when the drain arrives.
Model identification is straightforward: IKO stamps the series name on the underside of the curb and the back side of the membrane roll. For pre-sloped pans, look for the molded slope direction arrow and the drain center marking. If the stamping has worn off, we measure the foam density and the fabric backing to identify which series we’re working with. For most Jacksonville remodels, we recommend OEM IKO components when the existing system is less than three years old, since mixing OEM and aftermarket pan-to-drain connections is where leaks start. On older systems where the entire waterproofing assembly is being replaced anyway, a quality aftermarket equivalent like Schluter’s comparable line works fine and carries its own warranty.

Signs Your IKO Bathroom Remodeling Is Failing
- Grout that darkens after every shower and never fully dries. This almost always means water is sitting between the tile and the IKO membrane because the weep holes in the drain assembly are blocked or the membrane was never properly sloped to begin with.
- A soft or flexing shower floor, especially near the drain. The substrate beneath the IKO pan has absorbed water and begun to delaminate. In Jacksonville’s humidity, once this starts it does not self-correct, and the soft spot grows.
- Musty odor from the bathroom that returns within a day of cleaning. Mold is feeding on moisture trapped in the wall cavity behind the tile. The visible tile looks fine, which is why this gets ignored until a tile pops off.
- Water staining on the ceiling of the room below the bathroom. By the time this shows up, the IKO membrane has failed at a seam or at the drain flange, and the leak has been running for weeks or months.
- Cracked or lifting tile at the shower curb. The curb is the highest-stress point in any IKO install, and in Jacksonville homes with pier-and-beam foundations, minor settling cracks the curb before anything else shows wear.
If you’re seeing any of these, the right move is to have the shower evaluated before another shower cycle pushes more water into the framing. Our Jacksonville crews can inspect the assembly and tell you honestly whether it’s a targeted repair or a full replacement, and the estimate is written before anything is opened up.
Replacement Cost & What’s Included
A full IKO bathroom remodel in Jacksonville runs $9,000 – $28,000 installed. The spread comes down to three things: whether the existing waterproofing can be salvaged in sections or must be fully removed, what tile and fixtures you select, and whether the Jacksonville home’s subfloor needs repairs before any new work goes in. A small bathroom with a straightforward IKO pan replacement and basic tile falls at the lower end. A larger master bath with a custom IKO curbless shower, new vanity, and a Kohler or Moen fixture package lands higher.
Every Elmstead Remodeling Jacksonville quote includes the same line items, in plain language: demolition and debris removal, substrate repair, IKO membrane and drain installation, tile and grout, fixtures, and the final waterproofing test. No allowance line items that quietly grow. We hand over the written price before any work starts, and the 365-Day Done Right Promise stands behind the whole project: if it’s not done right, we make it right.

What you can safely do: confirm which IKO series you have by checking the stamp under the curb, take photos of any cracking or staining, and keep the shower dry while you decide. What you should not do: open the wall or pull up the pan to see how far the water damage goes. The moment you cut into the IKO membrane, you’ve changed the waterproofing envelope, and a partial DIY tear-out makes the eventual professional repair more expensive because now we’re matching two different waterproofing generations.
There is also the reality that the failed part is never just the part. The IKO membrane did its job until something around it moved, and in Jacksonville that something is usually the subfloor or the drain collar. That’s where the actual fix lives, and it typically involves tools and experience that a weekend project does not accommodate. Call (904) 643-6243 and we’ll schedule a walk-through, take the measurements, and write the price.
FAQs
A properly installed IKO waterproofing system in Jacksonville typically lasts 20 to 30 years, but the Florida humidity and regular settling of older Jacksonville homes mean the first point of failure is usually the drain connection or curb, not the membrane itself. Call (904) 643-6243 for an inspection if your shower is over 15 years old and showing any of the signs above.
Yes, if the failure is isolated to the drain assembly or a single seam, a targeted repair is often possible, but the tile still has to come off to reach the membrane, which is why many Jacksonville owners choose to remodel the shower properly once the tile is already open. We’ll tell you which path makes sense for your specific failure, and the written estimate spells out both options when a repair is viable.
A full IKO bathroom remodel in Jacksonville typically takes two to four weeks depending on scope, with the waterproofing and flood test taking three to four days of that window. We schedule around your family’s needs, including quiet hours for children’s sleep and pet-safe product choices where they’re available.
We carry common IKO drain assemblies, membrane patches, and corner pieces on our Jacksonville trucks, but we order the specific pan and series-matched components for your model once we’ve confirmed the measurements on site. That way the parts arrive correct the first time, not close enough. Call (904) 643-6243 to schedule a free estimate and we’ll verify what your shower needs.
