Unilock Bathroom Remodeling: The Dallas Owner’s Guide
Unilock bathroom remodeling in Dallas typically runs $9,000 – $28,000 installed, depending on the pavers or wall units you’re working with, the size of the space, and whether we’re rebuilding the shower base, replacing a failing mortar bed, or doing a full wet-area tear-out. Most Unilock owners call us when they notice the material failing, not when it still looks brand new: a paver floor that has started to shift near the drain, a wall unit that has cracked at a corner, or efflorescence (that white mineral haze) that keeps coming back no matter how many times it is scrubbed off. We stock Unilock-compatible materials on the truck for common Dallas-area repairs, and we can quote most jobs the same day we look at them.
If you’re like most Dallas homeowners we talk to, you discovered the problem at the worst possible moment: standing in a wet bathroom, looking at a floor that isn’t draining the way it used to, or a wall that has started to bow where it meets the tub. This page explains exactly what we can do with your Unilock product, what it costs, and how to tell whether you’re looking at a repair or a full remodel.
Which Unilock Models This Applies To
Unilock is best known in Dallas for hardscape products: pavers, wall units, and coping that show up in patios, pool decks, and driveways. But a lot of those products have found their way indoors, and we work on bathroom applications built from Unilock’s paver lines, wall blocks, and natural stone veneer. The most common Unilock products we see in Dallas bathrooms are Umbriano pavers used as shower floors, Brussels Block or Courtstone pavers used as bathroom flooring, and Linear or Estate wall units used for interior accent walls and tub surrounds.
Here is the compatibility gotcha every Unilock owner needs to know: Unilock changes product names and series availability by region, so the exact paver that was installed in a Dallas bathroom in 2014 may not be manufactured under the same name today. We match by physical measurement, color code printed on the pallet, and paver thickness, not by product name alone. Before we quote a repair, we measure the existing pavers with a caliper so we know the exact thickness tolerance, which matters more in a bathroom than a patio because you cannot hide a 1/8-inch height difference with sand in a shower.
For replacement material, we always price the OEM Unilock product first, then show you a comparable aftermarket option if one exists. With Umbriano, for example, the fine-grain surface finish is not easy to match with a generic paver. With Brussels Block, a quality aftermarket paver with the same dimensional specs can save real money if you are replacing the entire floor. We walk through both numbers in writing before anything comes out.
Styles & brands we work with
Signs Your Unilock Bathroom Remodeling Is Failing
- Pavers shift or rock underfoot near the drain. This usually means the mortar bed or sand-setting layer underneath has started to erode, which happens when the shower pan liner wasn’t sloped correctly in the first place, or when water has worked its way under the pavers over years of use in Dallas’s hard-water conditions.
- White mineral crust keeps coming back on the paver surface. That’s efflorescence, and it means water is moving through the paver and pulling salts to the surface. In a Dallas bathroom, the culprit is often a missing or failed membrane behind the wall or under the floor, not the paver itself.
- Hairline cracks at the corners of wall units, especially near the tub or shower pan. Corners crack when the substrate (the wall board or cement layer behind the unit) flexes. That flex comes from moisture getting in behind the wall, which is the bathroom-remodeling failure mode we see most often in Dallas homes built before modern waterproofing standards were common.
- Grout joints are crumbling and you’re finding sand or grit on the floor after every shower. Loose grout is the canary in the coal mine. It means water is already working its way into the setting bed below, and every shower puts more moisture where it shouldn’t be.
- Musty smell that won’t go away, or dark staining along the edges where pavers meet the wall. That’s trapped moisture behind or under the Unilock material. By the time you smell it, you usually have water damage in the substrate, and a cosmetic regrout will not fix it.

AfterReplacement Cost & What’s Included
Installed Unilock bathroom remodeling in Dallas runs $9,000 – $28,000. At the lower end, you’re looking at a small bathroom where we’re replacing the floor pavers, regrading the shower pan, and reinstalling existing fixtures. At the upper end, we’re rebuilding a larger bathroom from the subfloor and studs out: new waterproofing membrane, new Unilock-compatible wall units or veneer, new shower base, new fixtures, and new glass if the old enclosure is being replaced.
What drives the number up or down in Dallas specifically: the age of the home, because older homes in areas like Lakewood, East Dallas, and parts of Oak Cliff often have cast-iron drain lines or non-standard rough-in dimensions that require plumbing work before tile or pavers go down; the condition of the subfloor, which we inspect before quoting; and whether you want to match existing Unilock product exactly or switch to a new series with a different price point.
Every quote includes the material, the labor, the demo and haul-away, the waterproofing work, and a written line-item price. The number we give you before work starts is the number on the invoice. And every Unilock bathroom job carries our 365-Day Done Right Promise: if the work fails inside the guarantee period, 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 before you call. Look for loose pavers, visible cracks, and grout that has turned to powder. Check whether the shower floor drains completely within a minute or two after the water is off. Take photos of any product labels or packaging you still have, and measure one paver with a tape measure so we can start identifying what you’ve got before we even arrive.
What you shouldn’t do is attempt a DIY tear-out once water has gotten into the substrate. Bathroom substrates in Dallas homes hide mold, rotted subfloor, and damaged waterproofing that only becomes visible once you start pulling material. If you remove pavers and find black staining or soft wood, the job just went from cosmetic to structural, and you need a professional who can rebuild it correctly so the new Unilock material doesn’t fail the same way the old one did. Give us a call at (940) 204-5368 and we’ll take a look. The estimate is free, and you’ll get a written number before any work starts. That’s how we’ve always done it. Give you a number before I pick up a tool, that’s the only way I know how to start.
FAQs
In a properly waterproofed Dallas bathroom, Unilock pavers and wall units routinely last 20 to 30 years or more, because the material itself is dense and durable; what fails first is almost always the setting bed, the grout, or the waterproofing membrane underneath. The Texas heat itself is not the problem indoors, but hard-water mineral buildup and the moisture cycle of daily showers take a toll on grout and sealers far faster than the paver itself.
Sometimes, yes. If the pavers are in good shape and the problem is a small area of failed grout or a few loose pavers near the drain, we can often do a targeted repair without tearing out the entire floor. But if water has gotten underneath and the substrate is compromised, a patch job will fail within months because the underlying problem remains. We’ll tell you which situation you’re in before we quote, and you’ll see the recommendation in writing. Call (940) 204-5368 and we’ll inspect it for free.
Most Unilock bathroom remodeling projects in Dallas take one to three weeks, depending on whether we’re doing a floor repair or a full wet-area rebuild. A simple paver floor replacement can be done in four to six working days, while a full bathroom remodel with new waterproofing, wall units, and fixtures typically runs two to three weeks including demo, plumbing, and finish work. We give you a defined arrival window and a completion schedule in writing before the project starts.
We stock common Unilock-compatible materials on the truck for Dallas-area bathroom repairs, including Eden, Umbriano, and Courtstone pavers in the most requested color blends, plus setting materials, membrane, and grout. If your specific color or series isn’t on the truck, we source it directly from our Unilock distributor, which adds a few days to the schedule but guarantees a true product match. We also work with products from KraftMaid, Cambria, and Silestone when a Dallas bathroom remodel expands beyond the Unilock material, whether that means a vanity, a quartz countertop, or a new tub surround. Call (940) 204-5368 with your product details and we’ll confirm what’s available before you pay for anything.
