Unilock Bathroom Remodeling: The West Covina Owner’s Guide
Unilock bathroom remodeling in West Covina typically runs $9,000 to $28,000 installed, depending on whether you’re refreshing a small guest bath or gutting a primary suite down to the studs. Most homeowners in West Covina call us when the existing tile, waterproofing, or shower pan has failed – cracked grout, water staining on the ceiling below, or a shower floor that never quite dries. The telltale sign is usually a bathroom that worked fine for fifteen years and now won’t stop causing problems, no matter how much you scrub or recaulk.
What most people don’t realize is that Unilock pavers and retaining wall products are built for exterior hardscape, but plenty of West Covina homes built in the 1970s and 1980s used Unilock-style concrete pavers as a bathroom floor base or shower surround accent. When those start spalling (the surface flaking off in thin layers), it’s not a cleaning problem. It’s the substrate failing underneath, and no amount of sealer will fix it.
We stock the materials and the know-how to rip out failing Unilock surfaces in a bathroom and rebuild the space properly, with real waterproofing behind the tile. Written price before we touch a single tool. That’s how every job runs at Sawyer Remodel West Covina.
Which Unilock Models This Applies To
Unilock doesn’t make a dedicated bathroom line, which is exactly why this page exists. The pavers and wall units homeowners in West Covina used in bathrooms decades ago came from Unilock’s exterior catalog – most commonly the Brussels Block, Courtstone, and Mattoni pavers, along with the occasional Rivercrest wall unit used as a shower bench or tub surround. Those products were never rated for interior wet areas, and that’s the compatibility gotcha most contractors won’t tell you.
If you’re looking at a failing Unilock surface in your bathroom, the fix isn’t finding a matching paver. It’s replacing the whole assembly with products actually rated for continuous moisture exposure – porcelain tile, Schluter Kerdi waterproofing membrane, a sealed shower pan, and proper slope. We can reuse the Unilock paver as a decorative accent if you love the look, but only as a dry, non-structural element. For real compatibility, you want a remodeler who understands the difference between exterior hardscape and interior wet-room standards, not someone who treats them as interchangeable.
Sawyer Remodel West Covina is an independent remodeler, not affiliated with Unilock. We don’t sell Unilock parts. We solve what happens when Unilock products end up somewhere they shouldn’t.
Styles & brands we work with
Signs Your Unilock Bathroom Remodeling Is Failing
- Spalling or flaking on the paver surface. The top layer of concrete breaks away in thin sheets or chips. This means moisture has been getting into the paver and the freeze-thaw cycles in West Covina winters are working the surface apart. It’s not cosmetic – it’s structural breakdown.
- Persistent musty smell you can’t source. Water is trapped somewhere it shouldn’t be – behind a paver wall, under a paver floor, or inside a bench that was never waterproofed. By the time you smell it, mold has usually established itself and the framing behind it is compromised.
- Grout joints cracking in the same places over and over. Repaired grout that cracks again within a year means the substrate is flexing. In West Covina, clay-rich soils expand and contract with seasonal moisture, and older slabs move. A paver-on-concrete bathroom floor has no tolerance for that movement.
- Water staining on the ceiling or wall below the bathroom. This is the one that can’t wait. If you see a tan or brown ring on the drywall underneath your bathroom, water has already penetrated the pan or the waterproofing layer. The longer it sits, the more joist damage you’re paying for.
- Shower floor that stays wet for hours after use. A properly sloped shower should drain and dry within 30 to 45 minutes. Standing water means the slope has failed, the drain is set too high, or the paver surface is too porous and soaking up water like a sponge. All three point to a removal and rebuild, not a patch.

Vanities from KraftMaid, countertops from Cambria or Silestone, fixtures from Kohler or Toto – all priced line-by-line in your written quote. The number you approve is the number you pay. No change orders, no surprise line items. Every bathroom job includes our 365-Day Done Right Promise: if it’s not done right, we make it right, in writing, for a full year after we close out the job.
DIY or Call Us?
Here’s the straight answer. You can safely check a few things yourself: look for water stains on the ceiling below, run your hand along paver surfaces to feel for flaking, and note whether the shower floor drains dry in under an hour. That’s diagnosis, and it helps you describe the problem when you call.
What you should not do is start pulling up pavers or cutting into a shower pan. Once you break the surface, you’re into the waterproofing layer, and a wrong move there means water getting into framing you can’t see. That turns a $9,000 remodel into a $25,000 repair. As Luca Romano puts it: good work shows. Bad work shows up later. If you’re seeing the signs, call (341) 217-4204 and we’ll come take a look. The estimate is free, and you’ll have a written price before anything gets torn out.
FAQs
A full bathroom remodel with Unilock surface removal typically takes 3 to 5 weeks from demo to final inspection, depending on the size of the space and whether we’re moving plumbing. We’ll give you a schedule in writing before work starts, and you’ll get photo updates throughout so you can see progress without having to call and chase anyone down.
In nearly every case, no. Once Unilock pavers start spalling in a wet bathroom, the damage is through the surface and into the material. Surface sealers and topical patches fail within months because the underlying moisture problem hasn’t been addressed. A real fix means removing the failing material and rebuilding with products rated for continuous interior moisture. Call (341) 217-4204 and we’ll tell you honestly which side of that line your bathroom falls on.
We handle everything. We bring the demo tools, the waterproofing membrane, the tile, the fixtures, and the finish materials. You pick finishes from name-brand lines – KraftMaid cabinetry, Cambria and Silestone countertops, Kohler and Toto fixtures – and we order, deliver, and install. You never run to a supply house, and you never get handed a bare space and a list of things to buy.
No. The price we put in writing before work begins is the price you pay, period. That’s The Relay Visibility Guarantee, and it’s not optional on any Sawyer Remodel West Covina job. If we find hidden damage behind a wall, we stop, show you photos, and get written approval before proceeding – no surprise invoices, no “while we’re in here” add-ons.
If your Unilock bathroom surface is failing and you’re ready for a real fix, call (341) 217-4204 to schedule a free estimate. We’ll come out, look at the damage, and hand you a written price that covers the whole job. That’s how it should work.
