IKO Bathroom Remodeling: The Los Angeles Owner’s Guide
If you own a home in Los Angeles with IKO-branded bathroom fixtures or waterproofing components that have failed, you’re probably dealing with cracked seals, water staining on the ceiling below, or a shower pan that’s no longer holding water. We stock and install IKO-compatible bathroom remodeling components throughout Los Angeles, with complete bathroom remodels typically running $10,620 – $33,040 depending on scope, and we can usually start most repairs within the week. Most homeowners discover the problem the hard way: a damp spot on the drywall, a musty smell that won’t go away, or grout that keeps cracking no matter how many times it’s re-sealed.
Mason Remodeling Co Los Angeles is an independent service provider, not affiliated with IKO. That means we tell you straight what’s salvageable and what isn’t, and we’re not here to upsell you on brand loyalty when a better fix exists.
Which IKO Models This Applies To

IKO’s bathroom line covers a few distinct product categories, and the compatibility questions shift depending on which one you’re dealing with. For waterproofing membranes and shower pans, you’re looking at IKO’s Armourbase and AquaBarrier lines – both common in Los Angeles homes built or renovated between roughly 2008 and 2020. The failure pattern we see most often in LA: the pre-sloped foam tray loses its grade over time because the subfloor underneath settled, which channels water toward the wall instead of the drain. That’s a Los Angeles-specific reality, by the way – our clay-heavy soils move more than most, and a house that’s settled half an inch since 2010 can quietly ruin a shower pan that was installed perfectly level.
For IKO-branded wall panels and tub surrounds, the model number is usually stamped on the back side of an uninstalled panel or on the original packaging. If those are long gone, measure the panel thickness with a caliper – IKO panels run 4mm, 6mm, or 9mm, and that number matters for matching trim pieces. The gotcha we run into weekly: homeowners buy generic trim kits from a big-box store assuming they’re universal, then discover the IKO panel channels are 2mm narrower than the industry standard. They’re not. We match the exact OEM trim or source a quality aftermarket equivalent with the same channel spec.
If you’re not sure what you have, take a photo of the failed area and any visible labeling. We’ll identify it from the photo before we even schedule a visit.

Signs Your IKO Bathroom Remodeling Is Failing
- Persistent mildew smell that comes back within days of cleaning. This usually means water is trapped behind a panel or under the shower base where it can’t dry out. In Los Angeles’s low-humidity climate, a properly sealed bathroom should not smell like a locker room.
- Grout cracks that reappear in the same spots after re-grouting. Cracked grout near the floor-wall joint is rarely a grout problem. It’s movement behind the tile, often from a failing foam shower tray that’s compressing under foot traffic.
- Water stains on the ceiling of the room below. By the time you see this, water has been pooling under the shower base for weeks or months. The stain is the last symptom, not the first.
- Soft spots in the subfloor around the toilet or shower threshold. This is water damage, not a cosmetic issue. In Los Angeles’s older housing stock – think 1940s-to-1970s tract homes in the Valley and Mid-City – the subfloor was often plywood over joists with minimal waterproofing at transitions.
- Visible lifting or curling at panel seams. IKO panels are designed to sit tight at the seams. If edges are lifting, the adhesive has failed or the panel was installed with the wrong adhesive. Either way, water is getting behind it.

AfterReplacement Cost & What’s Included

A full IKO-compatible bathroom remodel in Los Angeles runs $10,620 – $33,040. A smaller job, like swapping a failed shower pan and re-waterproofing the surround, typically lands between $5,310 and $14,160 depending on access, the condition of the subfloor, and whether we’re matching existing tile or replacing it. Here’s how the range breaks down:
- Shower pan replacement with waterproofing: $5,310 – $14,160
- Tub-to-shower conversion (IKO-compatible system): $4,130 – $11,800
- Full bathroom remodel (cabinetry, fixtures, waterproofing, tile): $10,620 – $33,040
- Vanity replacement or installation: $945 – $3,540
Every quote is written and delivered before any work starts. That’s not a promotion – it’s how we’ve operated since 2004, and Isaac Pruett put it in writing as a company rule the year we opened. The written price includes all parts, labor, haul-away, and any permit fees. If the scope changes because we open a wall and find rotted framing, you’ll get a written change order before we touch it – never a surprise invoice at the end.
Every completed job carries a 365-Day Done Right Promise: if the work isn’t right within one year of the completion date, we return and make it right at no cost. That’s 365 days from completion, stated plainly.
DIY or Call Us?
Some things are worth checking yourself. If you see water staining, mark the outline with a pencil and check it again in a week – if it’s growing, the leak is active. If you smell mildew, pull off the drain cover and check for standing water in the trap area. Those are safe, useful diagnostics.
What you should not do: pull apart a shower base or cut into waterproofing membrane to “see what’s going on.” Once you break the waterproof barrier, you’ve turned a repairable leak into a full tear-out, and if the area has been wet for a while, you’re dealing with mold that needs proper containment, not a weekend scrub. This isn’t a scare tactic – it’s the reality of what we find on job sites across Los Angeles County every month. We’re licensed, insured and bonded, and every technician who comes to your door has been background-checked, identity-verified, and walks up wearing a clean uniform with a photo ID badge. You’ll know the name and see the photo before they arrive. That’s the Threshold Standard on every job.
If you’ve got water where it shouldn’t be, call us at (213) 632-5711. We’ll talk through what you’re seeing and tell you honestly whether it needs a pro or just a tube of caulk.
FAQs

A properly installed IKO-compatible shower system should last 15 – 25 years in Los Angeles’s climate, but the weak points are almost always at the seams and the drain connection. We see failures in 8 – 12 years when the original install skipped a proper slope check or used the wrong thin-set. Call (213) 632-5711 if you suspect a premature failure – estimates are free.
Sometimes, yes. If the failure is caught early and the surrounding tile and waterproofing are still intact, the pan can often be swapped without touching the rest of the bathroom. We’ll cut out the damaged section and inspect before recommending a full remodel. Call (213) 632-5711 and we’ll give you an honest read.
A shower pan replacement with re-waterproofing typically takes 3 – 5 working days, including dry time between coats and a 24-hour flood test before tile goes in. A full bathroom remodel runs 2 – 4 weeks depending on scope, and you’ll get a written schedule with your written price.
We keep common IKO-compatible trim, membranes, and shower base components in our Los Angeles inventory, and we also stock compatible parts from the brands we regularly install alongside IKO work: KraftMaid cabinetry, Cambria and Silestone surfaces. If we need to order a specific IKO part, it’s usually 3 – 5 business days in Los Angeles. We’ll confirm availability before you commit to anything.
Know who’s coming, know what it costs, know it’s guaranteed – everything else is just noise.
