Unilock Bathroom Remodeling: The Dallas Owner’s Guide
A full Unilock bathroom remodel in Dallas typically runs between $9,000 and $28,000 installed, depending on the size of the bathroom, the condition of the substrate, and whether you’re moving plumbing or keeping the existing rough-in. We stock Unilock-compatible materials and can usually begin within a week or two of your written approval. Most Dallas homeowners discover their bathroom needs this level of work when they pull back a loose tile and find the Unilock surface delaminating from water that’s been sneaking behind it for years.
What surprises people isn’t the tile itself. It’s what’s underneath. In Dallas, we deal with slab foundations and a lot of 1960s and 1970s construction where the original waterproofing was either nonexistent or has long since failed. When a Unilock paver or wall unit in a bathroom setting starts showing grout cracks, efflorescence, or soft spots, the visible problem is usually the last chapter of a longer story happening behind the surface. We’ll walk you through exactly what you’re looking at, what it costs, and what it takes to fix it right.
Key Takeaways:
- Dallas bathroom remodels using Unilock materials run $9,000 – $28,000 installed.
- Water intrusion behind the surface is the most common failure point in this market.
- We provide a written price before any work starts, and every job carries the 365-Day Done Right Promise.

Which Unilock Models This Applies To
Unilock makes a broad range of concrete pavers, wall units, and coping stones. In bathrooms, the products we most often see in Dallas are Unilock wall units and pavers used as shower floors, accent walls, or vanity surrounds. The compatibility question comes down to two things: the product series and the thickness of the unit. Unilock wall units, for example, come in different face dimensions and depths depending on the series, typically ranging from 3 inches to 6 inches deep. A wall unit designed for an exterior retaining application is not the same as a thinner paver suited to an interior surface.
The easiest way to identify your product is to check the back of the unit if it’s already out, or to measure the face dimensions and thickness if it’s still installed. Unilock embeds identifying information in their catalog, and once we know the series, we can match it. The OEM-versus-aftermarket decision matters here less than it does with mechanical parts. These are concrete units. What matters more is the color blend and face texture, because Unilock runs different pigment lots and a mismatched replacement stands out immediately. We work with Unilock-authorized distributors in the Dallas area to match series and color blend. If a discontinued color is the issue, we’ll give you a straight answer on what options exist before you spend another dollar.
Bradford Remodeling Co Dallas is an independent contractor. We are not affiliated with Unilock, but we install and source their products regularly, along with materials from KraftMaid, Cambria, and Silestone when the project calls for them.

Signs Your Unilock Bathroom Remodeling Is Failing
Here’s what we see most often in Dallas bathrooms, and what each symptom actually means:
- Grout cracking or falling out in a repeating pattern. This usually means the substrate behind the Unilock is flexing. In Dallas, slab settling and seasonal moisture swings in the soil cause enough movement to crack rigid grout lines. The fail can be up fine, but the movement underneath keeps transferring through.
- White, chalky residue on the surface (efflorescence). Water is moving through the concrete and carrying soluble salts to the surface. This tells us moisture is getting behind or through the Unilock unit, not just sitting on top of it.
- A hollow sound when you tap the surface. The bond between the Unilock unit and the thinset or mortar bed has broken. Water, movement, or an improper original install are the usual causes.
- Loose or shifting units when you step on them. On a shower floor, this is a safety issue as much as a cosmetic one. A moving paver means the setting bed is crumbling or the waterproofing has failed beneath it.
- Dark staining or a persistent musty smell. Water is trapped behind the surface and not drying out. In a Dallas bathroom, especially one without good ventilation, this can happen quickly once the moisture barrier is compromised.
None of these get better on their own. They all point to the same thing: the water management system behind the Unilock surface has stopped doing its job, and the surface is now just along for the ride.

AfterReplacement Cost & What’s Included
In Dallas, a complete Unilock bathroom remodel runs $9,000 to $28,000. The range is wide because bathroom size and the condition of what’s behind the surface drive most of the cost. Here’s how the numbers typically break down:
Typical Unilock Bathroom Remodel Costs in Dallas
| Scope | Installed Price Range |
|---|---|
| Full bathroom remodel (Unilock surfaces, fixtures, waterproofing) | $9,000 – $28,000 |
| Small bathroom remodel (half bath or compact full bath) | $5,000 – $12,000 |
| Walk-in shower with Unilock wall and floor units | $4,500 – $12,000 |
| Unilock accent wall or vanity surround only | $800 – $3,000 |
The gap between the low and high end comes from a few specific things: whether the existing waterproofing needs to be stripped and redone, whether plumbing stays in place or moves, and whether the substrate is sound enough to take new material. In older Dallas homes, we regularly find wood substrate or deteriorated mortar beds that add a day or two of correction before any new surface goes up. You’ll know this before we start, because it’s in the written price. Parts and labor are always line-itemed, and every completed job carries the 365-Day Done Right Promise. If the work fails within that first year, we come back and correct it at no charge. That’s the Garrison Standard, and it’s in writing every time.
DIY or Call Us?
There are a few things you can safely check on your own. Look for grout cracks, test for hollow spots with a gentle tap, and check whether any units move under light pressure. That tells you whether you have a problem and roughly where it lives. What you should not do is start pulling Unilock units off the wall to investigate. Once you break the surface, you’ve opened the waterproofing envelope, and without a plan and the right materials staged, you can turn a $2,000 repair into a $15,000 remodel in an afternoon.
There’s an honest tension here. The visible part of a Unilock bathroom surface is simple concrete. The part you can’t see, the waterproofing, the slope, the substrate preparation, is where the job gets decided. We’ve fixed enough DIY removals to tell you that the material is rarely the problem. The prep is. If you want to know what you’re actually dealing with, call (903) 326-8963 and we’ll give you a straight assessment. No charge for the look.
FAQs
A properly installed Unilock surface over a correctly prepped waterproofing system should last 20 to 30 years before the surface itself needs attention. What fails sooner in Dallas is almost never the Unilock unit, it’s the waterproofing behind it. Our soil moves, our humidity runs high, and bathrooms that don’t get regular ventilation develop moisture problems fast. If the original install skipped a proper moisture barrier, the surface can show problems in 5 to 10 years.
Sometimes, yes. If the substrate is still sound and the failure is isolated, individual units can be removed and reset. But when the waterproofing has failed, a patch job just moves the water to the next seam. We’ll tell you which situation you have before we quote anything. Call (903) 326-8963 for an exact assessment, free of charge.
Most single-bathroom Unilock remodels in Dallas take 2 to 4 weeks from demo to final grout, assuming the substrate is in reasonable shape. If we’re stripping back to studs or correcting foundation issues, that adds time we’ll show you in the schedule before work begins. You’ll have the timeline in writing alongside the price.
We order Unilock materials per project from authorized Dallas distributors so color blends and series match correctly. We don’t warehouse large quantities of concrete units, but we do keep the setting materials, waterproofing products, and fasteners on our trucks. That means we’re not standing in your bathroom waiting on a bag of thinset. The Unilock units arrive staged and ready for install on day one.
Straight number, real scope, no surprises on delivery day. That’s how we run every job, and it’s how Curtis Lane has run his crews across Dallas since the Lakewood gut-job days taught him what old plaster does to a schedule. If you want a contractor who puts the price in writing before anything gets touched, and who stands behind the work for a full year, call (903) 326-8963 to schedule your free estimate.
