Unilock Bathroom Remodeling: The Riverside Owner’s Guide
Unilock bathroom remodeling in Riverside typically runs $9,000 – $28,000 depending on whether you’re replacing a shower surround, retiling a floor, or rebuilding the whole wet area from the studs out. We keep our truck stocked with Unilock-compatible installation materials and can usually start within a week of your written estimate. Most Riverside homeowners call us after a grout line has cracked, water has crept behind their tile, or a curb has started to fail and they’re watching a small stain turn into a bigger one.
Here’s the thing about Unilock products in a bathroom: they’re built for exterior hardscape first. That matters in Riverside, where our houses see big temperature swings between summer afternoons and winter mornings. A paver or wall block outside handles that fine. But when Unilock materials get used inside a shower or around a tub, the failure point is almost never the stone itself. It’s what’s behind it and how it was set. That’s where we come in.
Which Unilock Models This Applies To
If you’ve got Unilock stone in your bathroom, you’re likely working with one of their modular wall or floor products repurposed for interior use. Common lines we see in Riverside homes include the Brussels Block, Courtstone, and the Estate Wall system cut down for shower benches or accent walls. The key identifier is on the back of the stone: Unilock stamps a batch code on most pavers and wall units. If you can’t find it, don’t worry. We measure the stone’s thickness, face profile, and joint width to match it before we write your estimate.
One compatibility gotcha almost nobody talks about: Unilock pavers run thicker than interior tile, usually 60mm to 80mm. Standard bathroom tile runs 8mm to 12mm. That extra thickness changes your floor height at the threshold and affects how your drain sits. If a previous contractor set Unilock directly over a standard shower pan without accounting for that, you’ll see water pooling where it shouldn’t. We correct for that on every install, and it’s one of the first things we check when we walk your Riverside bathroom.
OEM versus aftermarket framing here is less about the stone and more about the setting materials. Unilock itself doesn’t make setting systems. They rely on contractors to choose the right mortar bed, waterproofing membrane, and sealant. At Penhallow Remodeling Riverside, we use Schluter waterproofing systems under Unilock stone because the pairing is proven in wet environments. You get the look of the Unilock product with a substrate (the layer between your stone and the framing) that’s actually rated for a shower. That’s the difference between a bathroom that lasts 15 years and one that fails in six.

Signs Your Unilock Bathroom Remodeling Is Failing
- Grout cracking along the shower floor or bench. Unilock stone carries real weight. If the mortar bed underneath is too thin or the subfloor flexes, the grout cracks first. In Riverside’s older Arlington and Victoria neighborhoods, we see this a lot because the original subfloors weren’t designed for that load.
- Water staining at the base of the wall or outside the curb. Most Unilock bathroom failures are waterproofing failures, not stone failures. Once water gets behind the stone, it travels sideways along the framing and shows up where you least expect it.
- Loose or hollow-sounding stones when you tap them. A properly set paver sounds solid. A hollow thud means the bond has broken. Left alone, that stone cracks under foot or shifts and tears the membrane beneath it.
- Efflorescence, that white chalky film, that keeps coming back. Unilock concrete products are porous. In Riverside’s dry climate, water evaporates fast and leaves mineral deposits behind. If you scrub it off and it returns within a month, moisture is feeding it from behind.
- A shower that doesn’t dry out between uses. If the tile still feels damp six hours after a shower, your slope or drainage isn’t moving water the way it should. Unilock stone’s rough surface holds more water than glazed tile, so a proper slope matters even more.

AfterReplacement Cost & What’s Included
The two biggest cost drivers in a Riverside Unilock bathroom remodel are the size of the wet area and what we find when we open the wall. A shower surround replacement typically runs $9,000 – $16,000 here. A full bathroom remodel with Unilock stone, new vanity, fixtures, and corrected waterproofing runs $18,000 – $28,000. If we discover rotted framing or a relocated drain, that adds to the number, and we tell you before we do anything.
Every written estimate from us includes the parts, the labor, the demolition, the waterproofing system, and the cleanup. You don’t get a labor number and then a surprise materials bill later. Your price is your price. And because we’re part of the Kingswell family of companies, every Unilock bathroom project carries our 365-Day Done Right Promise in writing: if something fails inside that year, we come back and fix it. No service call, no re-inspection fee. Trevor Nash, our owner, signs every one of those guarantees himself.
DIY or Call Us?
You can safely check a few things yourself: look for loose stones, check the grout integrity around your drain, and note whether water is pooling. That’s information that helps us quote more accurately over the phone. What you shouldn’t do is pull up even one stone to look underneath. Once that waterproofing layer is breached, you’ve turned a repair into a tear-out. And cutting Unilock stone without the right blade produces silica dust you don’t want in your lungs. We’ve fixed enough “I watched a video” bathroom jobs in Riverside to know that saving $500 up front can cost $5,000 on the back end. Call (341) 895-1170 and we’ll give you a real number before any tool comes off the truck. Give you a number before we pick up a tool, that’s just how this works.
FAQs
How long does Unilock stone last in a Riverside bathroom? Properly set Unilock stone inside a bathroom can last 20 to 30 years in Riverside’s climate, but the setting system underneath it has a shorter service life, usually 10 to 15 years. If you’re seeing signs of failure, it’s more likely the waterproofing or mortar bed than the stone itself.
Can you repair Unilock bathroom stone instead of replacing the whole bathroom? If the stone itself is intact and the failure is isolated, like a cracked grout line or a single loose stone, we can often repair without a full tear-out. But if water has gotten behind the waterproofing, a patch job hides the problem instead of fixing it. The honest answer depends on what we find, and we’ll show you photos before recommending anything. Call (341) 895-1170 to walk through what you’re seeing.
How long does a Unilock bathroom remodel take in Riverside? Most Unilock shower surrounds take 5 to 7 working days. A full bathroom remodel runs 2 to 3 weeks depending on whether we’re moving plumbing or rebuilding the pan. We give you an arrival window before the job starts and we keep to it. That’s part of the written agreement.
Do you stock Unilock stone on your truck, or do you order it? We stock setting materials, waterproofing membranes, and common repair parts on our trucks, but Unilock stone itself is ordered per project because the batch codes need to match for a consistent color. If we’re doing a repair and need to match existing stone, we’ll pull a sample and source the closest available batch. We do the same for homeowners who’ve asked about matching KraftMaid, Cambria, or Silestone details elsewhere in the room.
Whether you need a shower rebuilt or the whole bathroom done right, the first step is a free written estimate. Call (341) 895-1170 and we’ll walk through what you have, what it’ll cost, and exactly what the guarantee covers. No tape measure left in the truck.
