Unilock Bathroom Remodeling: The Dallas Owner’s Guide
Unilock bathroom remodeling in Dallas typically runs $9,000 to $28,000 installed, covering everything from a failing paver floor system around a curbless shower to a full wet-room rebuild with Unilock hardscaping elements. Most Dallas homeowners call us after they notice shifting pavers, standing water pooling against a shower threshold, or grout lines cracking along a Unilock accent wall where bathroom humidity has finally won. We stock common Unilock replacement pavers, coping, and edge restraints on our trucks, and we can usually source discontinued or special-order Unilock pieces within three to five business days through our supplier network.
What most people don’t realize is that Unilock products inside a bathroom behave differently than Unilock products on a Dallas patio. Bathroom environments introduce constant moisture, temperature swings from hot showers, and cleaning chemicals that exterior pavers never face. When a Unilock paver floor or accent wall inside a bathroom starts failing, it’s rarely the paver itself. It’s almost always what’s underneath: the mortar bed, the drainage slope, or the waterproofing membrane. We see this constantly in Highland Park bathrooms that were originally done by landscapers who treated an interior space like an exterior one.
Isaac Pruett has walked enough Dallas remodels to know that a shifting Unilock paver inside a shower is never just about the paver. It’s about what’s behind it. We’ll get into that below.
Which Unilock Models This Applies To
Unilock doesn’t manufacture a dedicated “bathroom line.” What Dallas homeowners use in bathrooms are Unilock’s exterior hardscape products repurposed for interior wet areas: Thornbury pavers, Beacon Hill flagstone, Brussels Block, Courtstone, and occasionally Richcliff for accent walls. The compatibility gotcha is the thickness. Most Unilock pavers are 60mm to 80mm thick, which is far thicker than standard interior tile. That means your floor transitions need custom ramping or flush-set installation, and your drain assemblies must be set at exactly the right height. If the original installer didn’t account for that thickness, you get the classic Dallas failure: a shower floor that drains into the hallway instead of the drain.
Identifying your exact Unilock paver is straightforward if you still have a spare piece. Flip it over. Unilock stamps a product code and sometimes the series name on the underside, though older pieces may have worn or never had stamps. Measure the thickness with a tape measure. If you can’t find a stamp, take a photo in natural light and text it to us before you call, or describe the edge profile: beveled, tumbled, or straight. That gets us to the right match faster.
On OEM versus aftermarket: for Unilock specifically, we recommend OEM pieces whenever the paver is visible. Unilock’s color blending is proprietary, and aftermarket “lookalike” pavers from local suppliers in Dallas nearly always sit a half-shade off in bathroom lighting. For concealed pieces under a vanity or behind a toilet, a quality aftermarket equivalent saves real money with zero visual penalty. We’ll always tell you which situation you’re in before quoting.
Quick note on affiliation: Mason Remodeling Co Dallas is an independent contractor. We’re not owned by, affiliated with, or endorsed by Unilock. We just work with their products constantly and know where they fail.
Styles & brands we work with
Signs Your Unilock Bathroom Remodeling Is Failing
- Pavers are rocking or shifting underfoot. This means the mortar bed underneath has fractured or the sand-set base was used indoors where it should’ve been mortared. Sand-set is fine on a patio. In a bathroom, it moves, and so do the pavers.
- Water pools in one corner instead of draining. The original installer likely set the pavers level instead of pitched at 1/4 inch per foot toward the drain. Unilock’s thicker profile makes correcting the slope a full re-set, not a patch job. We see this most often in Oak Cliff remodels where a handyman replaced tile with pavers without rechecking the pan slope.
- Grout or joint sand is washing out or turning black. In a shower, this signals moisture is trapped beneath the paver surface. The waterproofing below has likely been compromised, or the joints were never sealed for interior use. Left alone, you’re growing mold in places you can’t see.
- Pavers near the drain sit lower than the surrounding floor. The drain assembly may be set too low for the 60mm-to-80mm Unilock thickness, or the drain grate is sitting directly on the pavers instead of being supported by the pan. This causes the telltale “sunken ring” look around the drain.
- Edge pavers along the curb or threshold are cracking. Unilock pavers are dense and strong, but interior curb edges take sharp corner impacts. A cracked edge paver often means the original cut didn’t leave enough bearing at the edge, leaving a weak overhang that snaps under foot traffic.
Replacement Cost & What’s Included
In Dallas, a Unilock bathroom remodel or repair runs from $9,000 to $28,000, with smaller scopes like a shower floor re-set landing at the lower end and full wet-room rebuilds climbing toward the top. The range breaks down like this:
- Shower floor paver re-set (mortar bed replacement, drain re-slope): $9,000 – $14,000
- Full Unilock shower surround with curbless entry: $12,000 – $20,000
- Complete Unilock wet-room conversion (floor, walls, drain system): $18,000 – $28,000
- Accent wall repair or partial rebuild: $9,000 – $15,000
What drives the price is what’s underneath. If the original waterproofing is intact and we’re re-setting pavers, you’re at the low end. If we’re pulling the pan and rebuilding the slope because moisture has reached the subfloor, you’re paying for demolition, waterproofing, and rebuild. Every quote includes parts, labor, debris removal, and a written line-item price before any work starts. No floating numbers on the final bill. The workmanship warranty runs 365 days from the completion date, and if something fails in that window, we return at no charge. That’s the Done Right Promise, stated plainly.

You can safely check a few things yourself: identify the paver thickness, take photos of the failing area, and verify whether the floor slopes toward the drain by pouring a cup of water and watching where it goes. You should not attempt to pull up a single paver to “take a look.” Once a paver comes up, you’ve broken the waterproofing seal, and whatever you find underneath is now a bigger problem than it was ten minutes earlier. Bathroom paver work also involves sharp edges, heavy pieces, and sometimes a compromised pan that’s been hiding water damage. A trained eye catches column rot or mold before it becomes a repair that doubles in scope.

FAQs
Properly installed Unilock pavers in an interior bathroom should last 25 to 40 years or more, with the paver itself rarely being the failure point. What fails first in Dallas is the mortar bed or waterproofing underneath, especially in homes built before modern membrane standards reached the Texas market. If your pavers are failing within 10 to 15 years of installation, the problem is almost always the base, not the paver. Call (432) 302-8761 and we’ll verify what’s happening before you spend on replacement pieces.
Yes, in most cases, a single cracked or stained Unilock paver can be repaired or swapped without redoing the entire floor, provided the underlying base is still solid. If the paver is a chipped edge, we can sometimes re-cut or re-profile it in place. If the paver is cracked through and the waterproofing below is compromised, a simple swap won’t solve the real problem. We’ll tell you which situation you have after one look. Call (432) 302-8761 for a free assessment.
A shower floor re-set in Dallas typically takes three to five working days. A full wet-room rebuild with new waterproofing runs one to two weeks depending on scope. The drying time for the mortar bed and waterproofing is the part people underestimate: you can’t rush those cure times in a humid Dallas bathroom. We give you a written timeline with the written price, and we call if anything changes.
We stock common Unilock Thornbury, Brussels Block, and Courtstone pieces on our trucks, along with edge restraints, drain adapters, and the correct mortar and sealants for interior installations. If you have a discontinued Unilock color or an unusual series, we source it from our Dallas supplier network, usually within three to five business days. Call (432) 302-8761 and tell us what you’re matching, and we’ll check availability while you’re on the phone.
