Unilock Bathroom Remodeling: The San Antonio Owner’s Guide
Unilock bathroom remodeling in San Antonio typically runs $9,000 – $28,000 installed, depending on whether you’re refreshing a small guest bath or gutting a primary suite down to the studs. We stock Unilock-compatible hardscape and surface materials, and our crew installs them with a written price before work starts. Most San Antonio homeowners call us after water has already found its way behind tile, or when a shower pan cracks along the Texas limestone substrate that shifts with our clay-heavy soil. The first sign is usually a soft spot in the grout line or a lingering musty smell that no amount of bleach knocks out.
Which Unilock Models This Applies To
Unilock is best known for pavers and retaining walls, but in bathroom work we see their surface and trim products spec’d into shower surrounds, vanity backsplashes, and wet-room floors. The compatibility gotcha most San Antonio homeowners hit is this: Unilock’s dimensional stone and paver lines are not all rated for interior wet-area use, and some textured finishes trap soap scum and hard-water scale from our mineral-heavy municipal supply. If the piece you’re replacing came from a Beacon Hill, Brussels Block, or Courtstone line, measure the exact face dimensions and thickness before you chase a match. Over the years, Unilock has adjusted tolerances between production runs, and a quarter-inch difference means a trip back to the yard. We’re an independent service provider, not affiliated with Unilock, but we work with their materials daily and know which aftermarket equivalents hold up under San Antonio’s hard water and humidity swings.

Signs Your Unilock Bathroom Remodeling Is Failing
- Grout lines darkening at the base of the shower pan. Water is wicking up from a failed pan liner or a cracked substrate. In San Antonio’s clay soil, slab movement cracks mortar beds, and once the path is open, it never seals itself.
- Tile or stone sounding hollow when tapped. The thinset bond has let go, usually from moisture or thermal cycling. One hollow tile is a warning; a half-dozen means the surface is ready to spall.
- Musty odor that returns within days of cleaning. Mold is growing behind the surface, not on it. The smell comes from moisture trapped in the wall cavity or under the pan.
- Loose or shifting paver-style floor pieces. Interior Unilock-style surfaces need a different base than exterior pavers. If someone installed them over a wood subfloor without proper isolation, they’ll shift within the first year.
- Cracked caulk at the tub or shower junction. This joint moves every time someone steps in. When the caulk splits and water follows, it’s a slow leak that shows up as ceiling stains in the room below.

AfterReplacement Cost & What’s Included
A full Unilock-style bathroom remodel in San Antonio sits in the $9,000 – $28,000 range. A small hall bath with a standard tub surround, new vanity, and basic surface replacement usually lands between $9,000 and $15,000. A larger primary bath with a walk-in shower, custom niches, and floor-to-ceiling surfaces can push past $20,000, especially when we’re correcting water damage or moving plumbing. The range is driven by square footage, whether we’re repairing substrate, and the finish level of the materials you choose. Every quote is written, line-itemed, and delivered before any tool comes off the truck. No change orders, no surprise invoices. We cover our installation with the 365-Day Done Right Promise: if anything isn’t right within a year of completion, we make it right at no cost to you. Call (254) 269-5071 and we’ll walk you through pricing for your specific bathroom size.
DIY or Call Us?
You can safely check a few things yourself: look for cracked grout, press on tiles to feel for hollow spots, and run your hand along the base of the shower pan for softness. What you shouldn’t do is pull up a single piece of flooring or open a shower wall. Once that surface is breached, whatever moisture is underneath needs to be dried, treated, or replaced before new material goes back down. Half the San Antonio repairs we handle started as a weekend DIY patch that trapped water behind it and doubled the eventual bill. If you’ve already got a tile loose or a grout line that won’t stay dry, call (254) 269-5071. We’ll tell you honestly whether it’s a quick fix or a full rebuild.
FAQs
A properly installed bathroom remodel with quality materials lasts 20 – 30 years in San Antonio before surface wear forces a refresh, but the waterproofing system underneath should hold for the life of the home. The failures we see are almost always from shortcuts in the pan or membrane install. Call (254) 269-5071 and we’ll explain what we check before we quote.
Small, hairline cracks in a wall tile can sometimes be epoxied and color-matched, but a cracked floor piece or shower pan is structural and almost always needs replacement. The repair vs. replace call comes down to whether water has reached the layer beneath. Call (254) 269-5071 for an honest assessment.
Most San Antonio bathroom remodels take 3 – 5 weeks from demo to final walkthrough, depending on size and whether we’re addressing water damage or moving plumbing. Quoted timelines are written into your price document. Call (254) 269-5071 and we’ll give you a realistic window for your specific job.
