Unilock Bathroom Remodeling: The Tampa Owner’s Guide
Bradford Remodeling Co Tampa installs Unilock bathroom hardscapes and ready-to-finish surrounds, with most full bathroom remodels in Tampa running $9,000 to $28,000 depending on whether we are pulling a tub, moving a drain, or wrapping an existing five-foot space. When a Unilock component fails in a Florida bathroom, it is almost always the substrate behind it, not the Unilock product itself. Tampa’s humidity punishes backer board that was never flashed or waterproofed correctly, and by the time the tile moves or the pan cracks, the damage has usually spread.
Most owners call us because they spot a hairline crack in a Unilock shower pan, a loose cap on a Unilock step, or grout that stays dark and wet for days after a shower. They want to know if it is a surface fix or a tear-out. Our answer is the same every time: we need to see the substrate before we quote a number, because the visible crack is rarely the whole story.
Which Unilock Models This Applies To
Unilock bathroom work in Tampa generally falls into three buckets: modular shower pans and surrounds, paver-style bathroom flooring, and Unilock thin veneer used as an accent wall or shower feature. The part numbers and dimensional specs vary by series. Unilock pans are manufactured as pre-sloped units with a consistent pitch toward the drain, but they are not universal, and a pan ordered for a center-drain layout will not fit a linear-drain rough-in without cutting the slope entirely out of the unit.
Before you order anything, check the underside of the pan or the back of a loose tile for the mold stamp. Unilock stamps their pans with the series code and the production date. If you cannot read the stamp, measure the pan’s outside dimensions and the drain offset from the wall. That offset is the compatibility gotcha that trips up a lot of Tampa homeowners. Center-drain and offset-drain pans look identical in a photo, but the pitch is engineered for one drain location, and a wrong guess means the pan pools water at the low corner. We match OEM Unilock parts when the warranty and color match matter. When the original series has been discontinued, we recommend a quality aftermarket pan with the same drain offset and slope profile, then we waterproof the seam to the substrate before the first tile goes down. We are an independent contractor, not a Unilock dealer, and we will tell you plainly when an aftermarket part is the better call for a discontinued series.

Signs Your Unilock Bathroom Remodeling Is Failing
- Grout that stays dark 24+ hours after a shower. That means water is wicking into the grout and sitting in the substrate. In Tampa, where indoor humidity rarely drops below 50 percent even with AC running, a substrate that never dries is a mold colony that just has not bloomed yet.
- A hollow sound when you tap the wall tile around the shower valve. Tile over a properly set waterproof membrane sounds dead, like tapping a book. Tile that has debonded from a failed backer board sounds like tapping a cardboard box. The tile may look fine for another six months. It is not fine.
- A pan crack that weeps a brown or rust-colored stain. The stain is the tell. It means the crack has reached the mortar bed, and the mortar has been saturated long enough to pull minerals up through the fracture. Surface cracks from impact are clean. Weeping cracks go all the way through.
- A musty smell that moves with the water heater. If the smell peaks when hot water runs, you are smelling the floor under the pan, not the drain. Hot water raises the vapor pressure and pushes whatever is growing down there up through the gap at the pan edge.
- Baseboard at the pan edge that has swelled or bubbled. Unilock pans sit on a mortar bed at the perimeter. When the bed saturates, moisture travels sideways into the drywall and trim. If your baseboard looks like it got wet from the bottom up, the pan edge seal has failed.
One honest safety note before we go further: a failed shower pan in a slab-on-grade Tampa home is not a weekend repair. The work involves cutting into waterproofing, inspecting framing, and sometimes removing tile with masonry blades. If the pan sits above a second-story ceiling, a leak that has been running for months can compromise the joists below. We have opened ceilings in Seminole Heights bungalows and found joist ends that read like wet newspaper because a pan failed two years earlier and nobody caught it. That is not a job for a caulk gun.

AfterReplacement Cost & What’s Included
A Unilock bathroom remodel that involves a pan replacement, substrate repair, and retile in Tampa typically runs between $9,000 and $28,000 fully installed. Where your job lands in that range depends on three things: whether we can save the existing waterproof envelope or need to tear it out to the studs; whether the drain location stays put or has to be replumbed; and whether the project is a three-piece tub surround or a full custom shower with niche work, a bench, and a frameless glass panel.
- Pan replacement with retile, drain stays put: $4,500 to $8,500
- Full tub-to-shower conversion with Unilock surround: $9,000 to $16,000
- Complete bathroom remodel, custom Unilock shower, vanities, flooring: $18,000 to $28,000
Every Bradford Remodeling Co Tampa quote is a written line-item price before any work starts. The parts cost is listed separately from labor and disposal. If the substrate turns out to be worse than we thought once we open the wall, we photograph it, we show you, and we price the correction as a written change order before we proceed, not as a surprise at close-out. Every completed job carries the 365-Day Done Right Promise in writing. If the work fails inside a year, we return and correct it at no charge. That guarantee covers our labor and the parts we supplied, and it is in your hand at job close.
DIY or Call Us?
Here is the straight split. You can safely check your Unilock pan’s stamp, measure the drain offset, and note whether the grout ever fully dries. You can take photos of the crack and the pan edge and have them ready when you call. That information saves us a site visit and gets you a tighter quote.
What you should not do is pull up the pan yourself, grind out grout, or silicone over the crack and hope it holds. The moment you break the waterproof seal, you have changed the scope of the repair, and you have often made the failure worse. A pan repair is only as good as the membrane underneath it, and a membrane that has been saturated for months is going to fail again behind your new tile. That is the most common thing we fix after a homeowner’s first attempt: a second failure, six months later, now with more damage and a bigger bill. If the pan is cracked or the grout will not dry, call us at (941) 655-9297. Curtis Lane and the crew will tell you plainly whether it is a repair or a replacement, and the estimate is free.
FAQs
A properly installed Unilock shower pan and surround over a correctly waterproofed substrate should last 20 to 30 years in Tampa, but the substrate bond and the grout will need maintenance every 5 to 7 years. The Florida humidity is harder on grout and sealant than the tile itself. If your installation failed in under 10 years, the problem was almost certainly the original waterproofing, not the Unilock product.
A surface hairline crack with no staining, no hollow sound, and a dry substrate under the pan edge can sometimes be cosmetically repaired with an epoxy-match kit and resealed. A crack that weeps, any crack you can fit a utility knife blade into, or any pan over a saturated substrate needs full replacement. We will not resell you a repair that will fail in a year; that is a waste of your money and a violation of everything we promised in writing.
A standard pan replacement with retile takes 2 to 3 working days including waterproofing cure time. A full tub-to-shower conversion with Unilock surround runs a week. A complete bathroom remodel runs 2 to 3 weeks. We price the schedule in writing, and we do not pull our crew off your job to start another one midweek.
We carry the common Unilock-compatible installation materials on our trucks: waterproofing membrane, bonding mortar, silicone sealants rated for continuous wet exposure, and grout in the standard Florida color lines. Specific Unilock pans and surrounds are ordered per job to match your series and drain offset. We also have ready access to KraftMaid cabinetry, Cambria and Silestone surfaces when the job includes vanities or countertops.
If you are looking at a failing Unilock shower and want a straight number before you spend another dollar, call us at (941) 655-9297. We will walk you through what to look for, give you a written price, and stand behind the work for a full year. Straight number, clear scope, no surprises at close-out.
