IKO Bathroom Remodeling: The Pasadena Owner’s Guide
A full IKO bathroom remodel in Pasadena typically runs $9,000 to $28,000 installed, and that price covers everything from demo to the final silicone bead. We stock the common IKO-compatible waterproofing membranes, shower trays, and trim profiles on the truck, so most jobs don’t stall waiting on parts. The way owners usually find us is mid-shower: water pooling where it shouldn’t, grout cracking along the pan, or that musty smell behind the vanity that means the waterproofing layer quit doing its job years ago.
IKO is a name most people know from roofing, but their shower and wet-area membrane systems are built on the same thinking: water moves, and whatever’s under your tile has to outlast the tile itself. When that layer fails, the tile job doesn’t matter anymore. You’re not looking at a cosmetic fix. You’re looking at gutting the wet area down to studs and rebuilding it right. That’s what we do, and we write the price down before the first hammer swings.
Which IKO Models This Applies To
IKO’s bathroom line splits into two rough families. There’s the sheet-membrane system (think IKO AquaBarrier and their flexible waterproofing sheets) used for wall cavities and behind tile backers. Then there are the pre-sloped shower trays and curb kits, usually paired with a bonded flange drain. The gotcha we see constantly in Pasadena’s older homes: the original installer used the tray with a mismatched drain from another brand, and the flange never sealed right. Water worked under the tray from day one, and by year three the subfloor is spongy.
If you’re hunting for a specific part, look for the model stamp on the drain flange or the corner of the membrane sheet. Trays have their size molded into the underside (common sizes: 32×60, 36×36, 48×48). For membranes, the roll label tells you the series and batch. IKO discontinued some older tray profiles after 2019, and we can usually match them with a current equivalent that fits the same drain height. Where it matters, we use genuine IKO parts. Where a quality aftermarket drains faster or levels better, we’ll tell you that too and show you the price difference before you decide.
Sawyer Remodel Pasadena is an independent remodeling contractor. We’re not affiliated with IKO, but we’ve torn enough of their failed installations apart to know exactly how the system should have gone together.

Signs Your IKO Bathroom Remodeling Is Failing
- Water stains on the ceiling below the bathroom. This one’s obvious but worth stating: the membrane leaked, and the stain you see is the lagging indicator. By the time it shows, framing has been wet for months. In Pasadena’s dry climate, that damage hides longer than it would in a humid market, because the water evaporates between showers instead of pooling visibly.
- Grout cracking along the shower pan perimeter. Movement of the tray or subfloor means the waterproofing bond has flexed past its limit. Re-grouting hides it for a few weeks. The substrate keeps moving underneath.
- Musty odor that returns within days of cleaning. That smell is mold in the wall cavity or under the pan. It’s not a cleaning problem. It’s a water management problem.
- Tiles sounding hollow when tapped near corners or drain. Sound means the thinset bond has broken. Air is sitting between tile and membrane. Water gets in, sits, and accelerates everything.
- Water running toward the wall instead of the drain. Pre-sloped trays have a set pitch. If the subfloor had a hump or the installer shimmed wrong, the tray follows the framing, not the engineer’s drawing. This is an install failure, not a product failure, and it means the entire pan comes out.

AfterReplacement Cost & What’s Included
In Pasadena, a full IKO system bathroom remodel lands between $9,000 and $28,000 depending on size, fixture choices, and how much structural repair the framing needs once we open the walls. A smaller hall bath with a standard tub surround sits at the low end. A primary bath with a custom walk-in shower, new vanity, heated floor, and glass enclosure climbs toward the top.
What drives the range: custom tile work versus standard subway, plumbing relocations, whether the old framing passes a level check, and your fixture picks. We don’t hide these variables. Our written estimate breaks the project into line items before you approve anything, exactly as The Relay Standard requires. The number on the invoice is the number you approved. Parts, labor, haul-away, and permit fees are in that number, not added later.
Every bathroom we remodel carries the 365-Day Done Right Promise. If something’s not right after the job closes, we come back and make it right. A full year, written on the contract.
DIY or Call Us?
You can replace a showerhead, a cartridge, maybe a vanity top. What you shouldn’t touch is anything behind the tile. Tearing into a waterproofing system without knowing how the drain flange ties into the tray is how a $1,200 pan fix becomes a $14,000 subfloor and joist replacement. The danger isn’t just water damage; it’s the false confidence of a bead of silicone over a failed membrane.
Luca Romano has been gutting Pasadena bathrooms long enough to say this plainly: if the pan is cracked, the grout is lifting, or the smell won’t leave, the fix is a rebuild, not a patch. The work tells you everything. You just have to know how to listen to it. If you’re not sure what you’re looking at, call (626) 657-5396 and we’ll tell you straight whether it’s a repair or a rebuild. Estimates are free.
FAQs
A properly installed IKO wet-area system with a quality tile job should give you 20 to 30 years in Pasadena’s dry climate, with the grout and silicone needing routine maintenance every few years. Failures we see before year five are almost always install-related: wrong drain pairing, skipped seam tape, or a tray set on unlevel subfloor.
No, not in any way we’d stand behind. Once water breaches the waterproofing layer, you can’t patch it from the tile side. The tile comes off, the membrane gets replaced or re-seamed correctly, and the pan is set right. Call (626) 657-5396 and we’ll give you an honest read on whether the full wall needs doing or just the wet zone.
A standard bathroom remodel in Pasadena runs 2 to 4 weeks from demo to final walkthrough, depending on tile work, plumbing changes, and inspection scheduling. We send photo updates before and after each phase so you watch the progress without babysitting the job.
We carry the common IKO AquaBarrier rolls, seam tapes, corner patches, and drain flanges on the truck, plus the matching fasteners and primers. For discontinued tray sizes, we order from our supply network, usually within 2 to 3 business days. If you need something we also stock parts for KraftMaid cabinetry, Cambria surfaces, and Silestone tops, ask and we’ll bring it the same day.
