IKO Bathroom Remodeling: The Los Angeles Owner’s Guide
If you’re searching for IKO bathroom remodeling in Los Angeles, the short answer is this: Bradford Remodeling installs and services IKO-compatible bathroom systems, and a full bathroom remodel in Los Angeles runs $10,620 to $33,040 installed, depending on size, substrate condition, and fixture selection. We’re an independent contractor, not an IKO dealer or affiliate, which means we match the right IKO materials to your existing setup without a sales quota behind the recommendation. Most homeowners call us after water has already found its way behind a shower wall or under a vanity, and by then the failure is usually in the waterproofing or the substrate, not the IKO surface material itself. You’ll want a straight answer on whether it’s a patch job or a full tear-out. That’s what this page is for.
Key Takeaways:
- IKO bathroom systems fail most often at seams, transitions, and substrate layers, not the finish surface.
- Installed bathroom remodels in Los Angeles run $10,620 – $33,040; a small bathroom remodel starts at $5,900.
- We give a written price before any work starts and cover the completed job with a 365-Day Done Right Promise.
Which IKO Models This Applies To
IKO manufactures a range of bathroom and wet-area membrane products, and the compatibility question always comes down to which system was originally installed. In Los Angeles homes we see two common setups. The first is the IKO water-resistive barrier used behind tile in tub surrounds and walk-in showers, typically a roll-on or sheet membrane tied into the shower pan. The second is the IKO underlayment or membrane that sits beneath vinyl or tile flooring in bathrooms where moisture has been a recurring problem. Identifying yours starts with the edge of the membrane. Look for the IKO logo printed along the roll or the exposed edge near the drain assembly. If it’s buried behind finished tile, we identify it during demo and match the replacement to the original spec.
One compatibility gotcha we see regularly: IKO membranes are not universally interchangeable with other manufacturer’s thinset and sealant systems. The upper layers of your shower assembly, the tile, the backing board, the sealant, are a system. Mixing a different brand’s waterproofing with whatever is on the truck can void the manufacturer’s performance warranty and shorten the life of the new tile work. For the IKO products we install, we use the manufacturer-specified compatible materials. That’s the difference between a patch and a repair that lasts.
OEM vs. aftermarket: For IKO-specific membranes, we use IKO OEM or an approved equivalent with the same ASTM rating. This isn’t a place to save $40. The membrane is the last line of defense between your shower and the framing. If it loses adhesion, the tile work fails from the back side, and you’re doing this job twice.
Styles & brands we work with
Signs Your IKO Bathroom Remodeling Is Failing
- Grout lines staying dark or damp in a dry room. Water is trapped behind the tile, which means the IKO membrane or the sealant at the pan-to-wall transition has been compromised. The grout soaks up moisture from behind, not from the surface.
- A sharp, musty smell that doesn’t go away with cleaning. That’s mold feeding on the framing or the back side of the cement board. By the time you smell it, the waterproofing layer has failed somewhere and moisture has been present for weeks.
- Tile that sounds hollow when you tap it. The thinset has lost bond, often because the substrate has swelled or flexed. In Los Angeles homes built before 1990, this is frequently a drywall-behind-tile problem rather than a proper cement board application.
- Cracking grout or cracked tile in a straight line. A straight crack follows the seam of the backer board behind it, which means movement in the wall assembly. The membrane may still be intact, but the assembly has flexed and the tile is failing.
- Floor tile lifting along one edge or in a corner near the tub or vanity. Water has wicked under the flooring and destroyed the adhesive. The IKO underlayment may have failed, or the seam was never sealed correctly during the original install.

AfterReplacement Cost & What’s Included
In Los Angeles, you’re looking at $10,620 to $33,040 for a full bathroom remodel that includes IKO-compatible waterproofing, new substrate, tile or surround installation, fixtures, and finish work. A small bathroom remodel (a standard 5×8 hall bath or a compact primary bath) runs $5,900 to $14,160. If the failing area is isolated to a walk-in shower, a full shower replacement runs $3,540 to $10,030. The spread comes from three things: how much rotten framing we uncover once the tile comes off, whether you’re doing a tub-to-shower conversion versus a like-for-like swap, and fixture grade. A Kohler or Moen fixture set versus builder-grade changes the line item, not the labor.
Every price we give is written down before any work starts. No numbers move at the door. You’ll see parts and labor separated on the estimate, and the warranty on the work is spelled out. That’s the 365-Day Done Right Promise: if the waterproofing or finish work fails within one year of completion, we return and correct it at no charge. Straight number, real scope, no surprises at the punch list.
DIY or Call Us?
There are things you can check without touching a tool. If you suspect a leak, stop using the shower for 48 hours and see if the damp smell fades. That tells you the water source. You can also inspect the exterior of the shower pan lip and the toilet wax ring area for discoloration. Those inspections cost you nothing and tell us a lot when we arrive.
What you shouldn’t do is peel back tile or cut into the wall to “find the leak.” Without knowing how the shower was built, you’ll destroy evidence of the failure mode and possibly make the repair more invasive. And if you uncover mold in the framing, you’re now dealing with spore spread through the house. Let us do the opening. The inspection and written estimate are free. Call (903) 568-7222 and we’ll schedule the visit.
FAQs
With correct installation, a properly tied-in IKO membrane behind a tile or surround assembly lasts 20 to 30 years in Los Angeles. The variables that shorten it are poor initial seam sealing, movement in the framing (we’re in earthquake country), and consistent humidity in baths without proper exhaust ventilation. Most failures we open up are installer errors, not material defects.
Sometimes. If the failure is localized, say a pan-to-wall seam or a single corner, we can open just that section, patch the membrane correctly, and re-tile the affected area. The catch is that the repair is only as good as the surrounding tile and grout. If the surrounding grout is cracked and the backer board is soft, you’re throwing money at a section of a failing assembly. We’ll tell you which situation you’re in before you spend a dollar.
A full bathroom tear-out and rebuild in Los Angeles runs four to six working days. A shower replacement runs three to four. The pace is driven by proper cure times on the waterproofing and setting materials. We sequence the work so the membrane is installed, tested, and given the manufacturer’s required cure time before tile goes up. Rushing that step is how you end up with a failure inside the first year.
We stock the standard IKO membrane sizes and the compatible sealants, corners, and pan-to-wall transition pieces on our trucks. For unusual shower sizes or commercial-grade systems, we order from our supplier in Los Angeles, which puts parts in our hands within one to two business days. Either way, the written estimate includes the materials cost at the time of the quote, so there’s no supply-chain surprise at the end.
Call (903) 568-7222 to schedule your free estimate. A real person answers, day or night. We’ll send a background-checked, uniformed technician to open the wall properly, tell you what’s actually failing, and hand you a written price before any work begins. That’s the Garrison Standard, and it’s how we’ve run every job since 2004.
