IKO Bathroom Remodeling Nationwide

IKO Bathroom Remodeling: The Sherman Oaks Owner’s Guide

IKO bathroom remodeling in Sherman Oaks typically runs $9,000-$28,000 for a full replacement, and we stock IKO-compatible waterproofing membranes, underlayment, and flashing components for same-day starts on most projects. Most Sherman Oaks homeowners discover their IKO system is failing when they spot water staining on drywall near the tub surround or feel soft spots in the subfloor after a shower - signs that the membrane or weep screed detail has compromised after years of Valley heat cycling.

Which IKO Models This Applies To

IKO’s Profor, Armourbase, and GoldShield membrane lines are the ones we see in Sherman Oaks bathrooms, especially in homes built between 1995 and 2015 along the Ventura Boulevard corridor and the hillside streets north of Mulholland. The Profor series uses a 40-mil thickness with a fleece backing; Armourbase steps to 60-mil for steam-shower applications. GoldShield is the newer peel-and-stick variant, thinner at 36-mil but with an aggressive adhesive that bonds to plywood or concrete subfloors without primer.

To identify what you have, check the membrane edge at a plumbing access panel or where the tile meets the tub flange. IKO stamps the series name and mil thickness every 24 inches along the roll edge. If the stamp is worn, measure the thickness with a caliper: Profor measures 1.02 mm, Armourbase 1.52 mm, GoldShield 0.91 mm. We are an independent service provider with no affiliation to IKO, and we source both OEM rolls and equivalent membranes from Noble Company and Schluter that meet or exceed the original spec.

Signs Your IKO Bathroom Remodeling Is Failing

• Soft or bouncy subfloor near the tub or shower. Water has breached the membrane at a seam or drain flange and saturated the plywood beneath. In Sherman Oaks, the dry climate can mask this for months because moisture evaporates quickly from the surface while the subfloor rots from below.
• Grout cracking in a consistent pattern along one wall. This usually means the membrane behind the tile has delaminated, allowing the backer board to flex independently of the studs. The crack follows the stud bay where the bond failed.
• Musty odor that returns after cleaning. IKO’s fleece-backed membranes can wick water laterally when the seam tape degrades, spreading moisture into wall cavities without visible surface staining. The smell is often the first signal.
• Tile popping loose in the shower pan or curb. The membrane beneath has developed a reverse lap - water flowing behind the tile hits the membrane and backs up, hydrostatically pressing the tile off the thinset bed.
• Water stains on the ceiling below a second-floor bathroom. This indicates a drain flange or valve penetration detail has failed. IKO’s clamping-ring drains require a specific two-step seal; if the first plumber skipped the inner dam, water tracks along the pipe.

Replacement Cost & What’s Included

Our Sherman Oaks bathroom remodels with IKO-compatible waterproofing start at $9,000 for a hall bath with standard tub-shower combo and run to $28,000 for a master with curbless shower, steam, and full tile. What drives the range: square footage, whether we need to sister or replace rotted subfloor (common in 1960s Valley homes with 1/2-inch plywood), and whether the drain location changes.

Every quote is a flat written price delivered before work starts, under Clause 1 of the Haven Standard. The number includes demolition, disposal, new IKO or equivalent membrane, backer board, tile-ready shower pan if needed, and all finish materials you select. Permits are pulled and inspections passed as required by Los Angeles Building Code. Our 365-Day Done Right Promise covers the work, and you receive a documented photo record of the substrate condition before we close the walls.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can remove a baseboard and probe the subfloor with a thin nail to check for softness, or run a shower for ten minutes and inspect the ceiling below with a flashlight. What you cannot safely do yourself is remove tile and membrane to assess the full damage. The membrane is embedded in thinset, and prying it loose without dust control exposes you to silica. More critically, if the subfloor is compromised, there’s no temporary fix that won’t make the eventual repair more expensive.

We’re background-checked, uniformed, and we show up with the membrane rolls already on the truck. Call (213) 221-0788 to schedule your free estimate. We’ll give you a written price before anyone picks up a tool.
