Unilock Bathroom Remodeling Nationwide

Unilock Bathroom Remodeling: The Los Angeles Owner’s Guide

Unilock bathroom remodeling in Los Angeles typically runs $10,620 – $33,040 for a full bathroom overhaul, and we stock the fixtures, valves, and trim kits to match most Unilock paver and hardscape-adjacent bath designs. Most homeowners call us because a shower valve seized, a drain assembly cracked, or tile set over a Unilock-style substrate has started to lift and the water damage is beginning to spread. The frustrating part is usually not that the part failed, it’s that you called three other companies and nobody could tell you whether the replacement would actually fit the existing opening.

Which Unilock Models This Applies To

Let’s be clear up front: Unilock is best known for pavers and retaining walls, not bathroom plumbing fixtures. When Los Angeles homeowners ask us about “Unilock bathroom remodeling,” they’re usually dealing with one of two things: a bathroom finished with Unilock-style stone or paver materials on the floor or shower surround, or a Decko drain/Unilock integrated drainage system that’s tied into a bathroom-adjacent patio or outdoor shower. We’re an independent remodeling contractor, not affiliated with Unilock, but we work with their stone lines regularly enough to know the tolerances.

On the material side, Unilock’s dimensional stone and paver products need a specific gap width and setting bed depth when used inside a wet bathroom. That’s different from what an exterior patio calls for. Interior bathrooms in LA require slope-to-drain of at least 1/4 inch per foot, and Unilock pavers are thicker than standard interior tile, so the shower pan needs to be recessed or the threshold will sit too high. The compatibility gotcha we see most often: someone sets Unilock pavers directly over a plywood subfloor without a decoupling membrane, and the first seasonal humidity swing in a Valley bathroom pops the grout lines. We check for that before quoting anything.

Signs Your Unilock Bathroom Remodeling Is Failing

• Grout crumbling along the shower floor edges. This usually means the substrate (the layer beneath the tile or stone) is flexing. With Unilock-style stone, that flex is often caused by an insufficient mortar bed or missing decoupling membrane. Left alone, water seeps into the subfloor and rot follows.
• Musty smell that won’t leave, even after cleaning. That’s trapped moisture behind the stone or tile face. In Los Angeles, our dry climate can mask this for months, but the inside of the wall cavity will tell a different story once a small section is opened.
• Drain assembly that gurgles or drains slower than it used to. If the bathroom ties into an exterior Unilock paver patio with a strip drain, the issue may be settled pavers that shifted the drainage pitch. Water backs up at the threshold instead of running off.
• Floor stones that sound hollow when tapped. A hollow sound means the stone has debonded from the mortar below. It’s a matter of time before a crack appears, and cracked natural stone in a wet area invites water underneath.
• Dark staining at the base of the shower curb or along exterior wall joints. That’s wicking moisture, and in a Unilock stone bathroom it often traces back to a missing or improperly sealed waterproofing layer behind the curb.

Replacement Cost & What’s Included

A full bathroom remodel in Los Angeles with Unilock-style stone or paver materials runs $10,620 – $33,040 depending on bathroom size, the condition of the existing subfloor, and whether we’re also replacing the drainage assembly. A smaller bathroom remodel falls in the $5,900 – $14,160 range. If the job is primarily a shower replacement involving wet-area stone and a new pan, plan for $3,540 – $10,030.

Every quote includes the written part price, written labor, and written disposal line items before any work starts. You’ll know what the stone costs, what the setting materials cost, and what our crew time costs. We don’t hand over a vague range and hope you won’t notice when the invoice lands higher. The work is covered by our 365-Day Done Right Promise: if something fails inside a year because of our installation, we come back and fix it at no charge, in writing, on every project.

DIY or Call Us?

You can safely check a few things yourself: look for visible cracks in the grout, test whether the floor stones flex underfoot, and run water to see where it pools. That’s useful information to have before you call. What we’d rather you not do is pry up a Unilock stone in a wet area to “see what’s underneath.” Once the waterproofing layer is breached, even a small exploratory hole lets water reach the subfloor, and the repair cost climbs quickly from there. Removing stone over a failed mortar bed without cutting into adjacent material is a job for someone who has done it hundreds of times. One wrong angle and you crack the stone you were trying to save. Call us at (936) 259-2607 and we’ll give you a straight answer about whether it’s worth saving.
