Owens Corning Bathroom Remodeling: The Woodland Hills Owner’s Guide
Owens Corning bathroom remodeling in Woodland Hills typically runs $9,000 – $28,000 installed, and most full tear-out-and-rebuild projects take two to four weeks depending on scope. You’re here because something failed: a shower surround cracked at the corner, a bathroom ceiling shows water staining from above, or the flooring underneath your old tub finally gave out and you want the next build done with materials that don’t fail the same way. Owens Corning is known for insulation and building science products, and in bathrooms that translates to moisture management, waterproof backing systems, and the structural materials that keep tile, surrounds, and flooring from rotting out from behind. This page covers which Owens Corning products we work with, what fails first, and what a proper replacement actually costs in the 91364 and surrounding zip codes.
Key Takeaways:
- We install bathrooms built around Owens Corning waterproofing and backing systems, plus brands we stock parts for: KraftMaid, Cambria, and Silestone.
- Written price before any work starts, so the $9,000 – $28,000 range gets locked to a specific number before we touch a tool.
- 365-Day Done Right Promise covers every Woodland Hills bathroom remodel we complete.
- We’re an independent contractor, not affiliated with Owens Corning, and we say so plainly.
Which Owens Corning Models This Applies To
Owens Corning’s footprint in bathrooms is less about a named “model” and more about the product families that show up behind and under the finishes. The ones we see most in Woodland Hills homes are Owens Corning Foamular rigid foam backer panels (the pink or green boards behind shower surrounds), Owens Corning fiberglass batt insulation in bathroom exterior walls, and Owens Corning basement and crawlspace moisture barriers that protect the floor assembly under a bathroom. If your bathroom sits over a garage or crawlspace, that underlayment is doing the same waterproofing work the tile does on top. The compatibility gotcha: Foamular panels come in 1/4″, 1/2″, and 1″ thicknesses, and the 1/2″ is the one rated for direct tile and surround backing. Homeowners who grab the 1/4″ panel from a big-box store to save money end up with a spongy wall that flexes under grout lines and cracks within a year. Check the edge stamp on any existing panel and match it to the replacement spec, not just the label on the shelf. For shower surrounds and wall boards that carry the Owens Corning name as a system component, the OEM vs aftermarket decision usually comes down to dimension matching: OC panels are square-edged, and some competitor boards have shiplap or tongue-and-groove edges that change the finished wall thickness. We stock the common dimensions on our trucks and special-order anything odd the same week.
Styles & brands we work with
Signs Your Owens Corning Bathroom Remodeling Is Failing
- Grout lines cracking in a straight vertical or horizontal pattern. This is almost never the grout’s fault. It’s the backing panel flexing behind the tile because the wrong thickness was installed, or fasteners were driven too deep and broke the panel face. The fix means opening the wall.
- A soft spot on the bathroom floor near the tub or shower curb. Water has been getting under the flooring and the subfloor or underlayment is losing integrity. In Woodland Hills, this often traces to a failed seal at the tub flange or a shower door that was never caulked properly on the outside.
- Musty smell that returns within days of cleaning. Moisture is trapped behind a surface. Owens Corning batt insulation in an exterior bathroom wall that got wet loses its R-value and never dries out on its own in our coastal-influenced humidity. You smell what’s growing behind the wall.
- Tile or surround panels pulling away at the corner seams. The backing has swelled or rotted enough that the mechanical bond is gone. Caulk over the gap won’t fix it. The panel needs to come out and the substrate behind it needs to be replaced.
- Peeling paint or bubbling drywall on the ceiling below a second-floor bathroom. The waterproof layer under the bathroom floor has failed and water is traveling down. This is the one to act on fastest: what you see on the ceiling is only the end of the leak path, and the damage above is worse.
Replacement Cost & What’s Included
Full Owens Corning-system bathroom remodeling in Woodland Hills runs $9,000 – $28,000 depending on size, fixture grade, and how much of the failed substrate has to come out. A small standalone shower rebuild with new backing board, waterproofing, tile, and a new valve usually lands between $4,500 and $12,000. A full second-floor bathroom with tub-to-shower conversion, new flooring, new subfloor, and Owens Corning insulation replacement runs toward the higher end of the range. Every quote we write is a line-item price: materials, labor, disposal, and permits broken out so nothing shows up as a surprise line at the end. The 365-Day Done Right Promise covers the workmanship for a full year, and manufacturer warranties on Owens Corning materials stay in your hands with all documentation. If it fails because we made a mistake, we return and fix it. No charge and no argument.

Some things you can check safely before anyone shows up. Remove the shower escutcheon plate and look for standing water behind it. Run the shower and watch the tub or pan from underneath if you have access from a crawlspace or lower floor. Those observations help us quote accurately. What you should not do is pull tile off a wall to inspect the backing board. Once you break the waterproof layer, you’ve created the exact leak you’re trying to prevent, and a partially opened wall wicks moisture for days before anyone can get to it. If the failure involves an upstairs bathroom with water showing on the ceiling below, stop using the bathroom and call (341) 217-2776. We’ll schedule a look, give you a written price, and tell you exactly what has to come out before anything goes back in.
FAQs
A properly installed Owens Corning Foamular backer system and waterproofing layer should last 20 to 30 years in Woodland Hills before any material breakdown, but the typical failure point is the sealant and thin-set bond layer at the 10-to-15-year mark, not the panel itself. The catch: once water gets behind the tile, the clock starts on the wood framing, not the panel. Call (341) 217-2776 if you suspect water intrusion; earlier diagnosis means a smaller repair instead of a full gut.
In most cases, no. A cracked Owens Corning backer panel behind tile cannot be patched from the front without losing the waterproofing continuity. The section that failed gets removed, the framing behind it gets inspected and dried, and new panel goes in with proper fastening and seam treatment. That’s the only repair that holds.
Two to four weeks for a full Woodland Hills bathroom remodel, depending on whether we’re moving plumbing, how much subfloor comes out, and tile selection. Smaller shower rebuilds can be done in five to seven working days. You’ll get a schedule up front with a live arrival time and photo updates before and after each phase, per The Relay Visibility Guarantee.
We stock the common Owens Corning Foamular thicknesses and backing systems on our trucks and source the rest through our supplier network, which includes KraftMaid, Cambria, and Silestone for the finish side. We handle procurement, delivery, and warranty registration. You don’t chase parts; that’s our job.
