IKO Bathroom Remodeling: The Orange County Owner’s Guide
IKO bathroom remodeling in Orange County typically runs $9,000 to $28,000 installed, and we stock the IKO-compatible waterproofing membranes, shower bases, and backer materials needed to get the job moving without a two-week wait on a special order. Most Orange County homeowners don’t discover an IKO component issue until water has already found its way behind the tile or into the subfloor. They see a loose tile, a soft spot near the curb, or a stain crawling up the drywall outside the shower. What started as a grout crack is now a substrate problem, and the fix has to be done right the first time.
We are an independent Orange County contractor, not an IKO dealer or affiliate. That matters because we are not tied to pushing one manufacturer’s full system. If an IKO membrane is the right call for your shower rebuild, we use it. If a compatible alternative gives you a better warranty at the same or lower price, we tell you that too and put it in writing before the first tool comes out.
Key takeaways:
- Installed IKO bathroom remodeling in Orange County: $9,000 – $28,000, with most shower rebuilds landing between $12,000 and $19,000.
- Most IKO “failures” are actually installation errors at the seams or improper slope, not a defect in the membrane itself.
- Every Bradford Remodeling Co Orange County job gets a written price before work starts and the 365-Day Done Right Promise in writing at close.

Which IKO Models This Applies To
IKO manufactures several membrane and underlayment lines used in Orange County bathroom builds. The most common we see in showers and wet areas are the IKO ArmourGard and IKO AquaBarrier membrane products, along with their peel-and-stick flashings and shower pan liners. The compatibility gotcha most homeowners miss is this: IKO membranes are not all rated for continuous water immersion the way a PVC pan liner is. Some are vapor barriers only. If the wrong product was used under your tile, it will hold up for a few years, then fail exactly where you’d expect, at the curb and the drain collar.
Identifying what you have is straightforward if the original installer left the building wrap or membrane label exposed, but that almost never survives a finished bathroom. We check for product stamps on any exposed flashing, measure the membrane thickness at the drain cutout, and verify the slope with a level before quoting. If you are replacing an IKO membrane, we spec an OEM IKO product when the existing system is intact enough to tie into cleanly. When the substrate is too far gone to trust a patch, we recommend a full tear-out and a compatible waterproofing system with a manufacturer warranty that matches the work.
What fails first on IKO bathroom installations in Orange County: seam adhesion. Our climate swings between dry inland heat and coastal humidity, and that thermal cycling puts real stress on lapped seams. If the original installer skimped on primer or rolled a seam with air pockets, that is where water gets in. We see it most often in homes built in the 2005 – 2015 wave across Anaheim Hills, Yorba Linda, and Mission Viejo, where production-speed remodels were common.
Styles & brands we work with
Signs Your IKO Bathroom Remodeling Is Failing
- Grout cracks that keep coming back. Repeated cracking along the same lines usually means the substrate is flexing, not a grout problem. If the IKO membrane was installed over a spongy subfloor or without proper thinset coverage, the tile assembly moves slightly with every step, and the grout is the first thing to tell you.
- A musty smell you cannot locate. Water trapped behind tile or inside a curb assembly goes stagnant. The smell is often strongest in the morning before the room is ventilated, and it usually means the membrane has been breached long enough for mold to establish in the wall cavity.
- Loose or hollow-sounding tiles near the shower floor. Tap the tile with a wooden spoon handle. A hollow thud means the thinset has lost bond. When it happens at the perimeter of the shower floor, suspect water wicking up from a failed pan liner seam.
- Staining or bubbling paint on the wall behind the shower valve. Water traveling behind tile will escape through the path of least resistance, often around the plumbing penetrations. If the drywall on the other side of that wall is discolored, the moisture source is inside the wall, not on the surface.
- A shower curb that feels soft underfoot. The curb is the number one failure point we repair in Orange County. A properly waterproofed curb is solid and unyielding. Softness means the wood framing inside has been absorbing water, and by the time you can feel it, the rot is established.

AfterReplacement Cost & What’s Included
In Orange County, an IKO bathroom remodel runs $9,000 to $28,000 depending on scope. A targeted repair of a failed curb or pan area, where we remove and rebuild only the wet section, lands on the lower end. A full shower tear-out with new IKO membrane, substrate, tile, fixtures, and glass runs higher. Here is the honest range breakdown:
| Scope | Typical Orange County Range |
|---|---|
| Partial IKO membrane repair (curb/pan) | $3,000 – $6,500 |
| Full shower rebuild with IKO waterproofing | $9,000 – $19,000 |
| Complete bathroom remodel with IKO system | $14,000 – $28,000 |
What drives the price inside that range: whether the subfloor and wall framing are sound (we do not waterproof over rot), the size of the tiled area, the fixture level you choose from our documented brand roster, Kohler and Moen among them, and whether the layout changes enough to require moving the rough-in. Every quote from Bradford Remodeling Co Orange County includes a line-item breakdown, a written scope, and the 365-Day Done Right Promise in writing before you sign anything.
You will not get a change order at the door. If we open the wall and find something we could not see at quote, we stop, show you the condition, and give you a written number to address it. No surprises at final invoice.
DIY or Call Us?
If you suspect an IKO membrane failure, there is a useful check you can do without touching a tool: dry the shower completely, tape plastic sheeting over the drain, fill the pan with an inch of water, and mark the water line. Check it in 24 hours. If the level dropped, water is escaping somewhere. That test costs you nothing and tells us a lot before we even arrive.
What you should not do is open the wall or cut into the pan yourself. Once you breach the waterproofing layer, you have just expanded the scope of the repair and possibly voided any remaining material warranty. Shower waterproofing is a system. The membrane, the slope, the drain collar, and the curb all have to tie together, and one wrong lap or a low spot in the mortar bed means the whole thing fails again in two years. Our crews have torn out enough DIY patches in Orange County to know the pattern: it costs more to fix a botched repair than it would have cost to do it right the first time.
Call (562) 262-2907. Curtis Lane will walk the job with you, give you a straight number, and put the scope in writing. Straight number, clear scope, no surprises at final invoice.
FAQs
A properly installed IKO membrane in a shower application should last 20 to 30 years, but improper slope, poor seam work, or wrong-product selection can shorten that to under a decade. The tile and grout are wear surfaces, not waterproofing, and they typically need maintenance long before the membrane gives out. Call (562) 262-2907 and we will inspect the install before you spend money guessing.
It depends on where the water has traveled and what condition the substrate is in. A curb-only failure is often repairable with a targeted rebuild. If the membrane failed at the drain or water has wicked into the wall framing, a full tear-out is the honest recommendation. We will show you the condition before we quote the repair, and the written price covers the actual scope, not a guess.
Most full shower rebuilds with IKO waterproofing take 2 to 3 weeks from tear-out to grout cure. The waterproofing layers need proper cure time between coats, and we do not rush that. Partial repairs can often be completed in 4 to 7 days. Call (562) 262-2907 for a realistic timeline on your specific project.
We stock the common IKO membrane widths and compatible drain collars, curb materials, and backer board on the truck for most Orange County service calls. Unusual sizes or special-order wallboard can add a few days. We also work with KraftMaid, Cambria, and Silestone on the finishing side, so if your remodel extends beyond the shower, the same crew handles it.
