Unilock Bathroom Remodeling: The Miami Owner’s Guide
Unilock bathroom remodeling in Miami typically runs $10,620 to $33,040 installed, depending on whether you’re replacing a failing shower pan, rebuilding a curb, or redoing the entire wet area with Unilock-compatible hardscape and tile systems. Most owners discover their Unilock product is failing when they notice efflorescence blooming across the surface, hairline cracks running through the substrate, or pooling water that no longer drains the way it did the year before. The good news is that we stock Unilock-compatible components on our trucks and can usually diagnose the exact failure point during the first visit.
A quick note before we go further: Mason Remodeling Co Miami is an independent contractor and not affiliated with Unilock. We work with their products often because they hold up well in South Florida’s humidity and salt air, but we’re a separate company. If you’re reading this, you probably have a specific problem and want to know if it’s worth fixing. It usually is. Here’s what you need to know.
Key Takeaways
- Installed Unilock bathroom remodeling in Miami: $10,620 to $33,040
- We stock Unilock-compatible edging, sealers, and setting materials on the truck
- Most failures trace to improper slope, wrong mortar, or missing waterproofing underneath
- Every job comes with a written price before work starts, plus the 365-Day Done Right Promise
Which Unilock Models This Applies To
Unilock is primarily known for pavers and retaining wall systems, but their product line extends into bathroom and wet-area applications through their surface and edge products. The most common Unilock items we see in Miami bathrooms are their natural stone and concrete paver lines used for shower floors, bathroom accent walls, and transition strips between tile and paver surfaces. If you have a Unilock paver floor in a steam shower or a Unilock edge restraint acting as a Schluter strip replacement (the metal trim that seals the edge where tile meets flooring), this page covers what fails and what it costs to fix.
Identifying your exact product matters. Check the back of a loose paver or the underside of an edge piece for a stamped code beginning with “UN” followed by four digits. That code tells us the series, color run, and dimensional spec. If you can’t read it, measure the piece: Unilock bathroom pavers come in 60mm, 80mm, and 100mm thicknesses, and mixing these up during a repair is the single most common DIY mistake we see. The 60mm line is rated for dry interior use only. The 80mm and 100mm lines handle continuous moisture. Using dry-rated units in a shower pan is why some Miami bathrooms fail within two years.
When it comes to OEM versus aftermarket, here’s the honest split. Unilock OEM edge restraints and setting compounds are consistent and we use them when the job calls for it. But for modified thin-set mortars and waterproofing membranes beneath the Unilock surface, quality aftermarket products like Laticrete and Schluter systems often outperform the OEM alternatives in humid climates. We’ll tell you exactly which combination we’d use on your job and why, with real prices for both options.
Styles & brands we work with
Signs Your Unilock Bathroom Remodeling Is Failing
- Efflorescence across the paver surface. That chalky white residue means water is moving through the substrate and pulling minerals to the surface. In Miami, where ambient humidity rarely drops below 70%, this usually means the waterproofing layer beneath the Unilock pavers has breached and the setting bed is saturated.
- Hollow-sounding pavers when tapped. A properly set Unilock paver should sound solid. A hollow thud means the thin-set has debonded, often because the original installer used an unmodified mortar in a wet area or didn’t back-butter the pavers. This is a teardown situation, not a patch.
- Water pooling in corners or against the curb. Unilock pavers don’t fail on their own. When water pools, the slope beneath them is wrong. The fix requires pulling the pavers, re-screeding the mortar bed to a 1/4-inch-per-foot slope, and resetting everything. If you ignore it, you’ll get mold under the pavers within a season.
- Loose or shifting edge restraints. If the Unilock edge piece pulls away from the wall or floor transition, the expansion joint has failed. This is more than cosmetic. Once the edge is compromised, water travels behind the restraint and into the wall cavity or subfloor.
- Cracks running in straight lines along grout joints. Unilock pavers are modular, but they still move with the building. A straight-line crack means the substrate flexed. In Miami, that’s often slab settlement, or it can be thermal expansion if the bathroom gets direct sun through a window. Either way, the crack tells us the original install didn’t account for movement.
Replacement Cost & What’s Included
For a full Unilock bathroom remodel in Miami, expect $10,620 to $33,040. The spread is wide because bathrooms vary enormously. A small guest bath with a standard shower pan and Unilock accents might land near $10,600. A master bath with a full Unilock paver floor, rebuilt curb, custom edge restraints, and a new waterproofing system can push past $33,000.
Here’s how the cost breaks down on a typical Miami Unilock bathroom project:
| Scope of Work | Installed Price Range |
|---|---|
| Unilock shower floor paver replacement (includes waterproofing membrane) | $3,540 – $10,030 |
| Full bathroom remodel with Unilock surfaces | $10,620 – $33,040 |
| Small bathroom remodel (compact wet area, Unilock accents) | $5,900 – $14,160 |
| Unilock edge restraint and transition replacement | $945 – $3,540 |
| Tub-to-shower conversion with Unilock surround | $4,130 – $11,800 |
Every quote includes demolition of the failed area, substrate inspection, replacement mortar bed, waterproofing, Unilock-compatible materials, and clean-up. You’ll get a written price before any work starts, with line items, so there are no surprise invoices. The work carries our 365-Day Done Right Promise: if something isn’t right within a year of completion, we come back and make it right at no cost. That’s 365 days from the completion date, stated in writing.

You can safely do a few things yourself. Check for visible water stains on the ceiling below the bathroom. Test whether pavers have hollow sounds by tapping with a wooden spoon handle. Look for efflorescence and measure the slope with a basic level. These observations help us diagnose faster when we arrive.
What you shouldn’t do is pull pavers yourself. In most Miami bathrooms with Unilock floors, the pavers sit directly on a waterproofing membrane. Chiseling them out without damaging that membrane is skilled work. One wrong swing with a hammer and chisel punctures the waterproofing layer, and now you’ve turned a paver repair into a full shower pan rebuild. The risk isn’t physical injury here; it’s turning a $2,500 repair into an $18,000 teardown. If you’re anywhere near Coconut Grove, Coral Gables, or Kendall, we’re your neighbor.

FAQs
An Unilock bathroom installation in Miami should last 15 to 25 years if the waterproofing below was done right and the slope is correct. The pavers themselves rarely fail. What fails in South Florida’s humidity is usually the setting bed, the waterproofing membrane, or the edge restraint. We regularly see Unilock pavers that are perfectly intact sitting on a substrate that has turned to mush. The paver is the last thing to go.
In most cases, yes. If a few pavers have debonded, we can remove them, clean the back, reset them with a modified thin-set rated for continuous moisture, and regrout the joints. That kind of spot repair runs $945 to $3,540 depending on how many pavers and whether the membrane underneath is still intact. If the membrane failed, repair isn’t possible and a full reset is needed.
Most Unilock bathroom remodels in Miami take 5 to 10 working days from demolition to final grout. A spot repair of a few pavers can be done in a day. The real schedule driver is waterproofing cure time. We don’t skip cure times to hit a date. When Isaac Pruett quotes you a schedule, that schedule includes proper cure time, not just the demo and install days.
We keep Unilock-compatible edge restraints, setting compounds, sealers, and grouts on our trucks. For actual Unilock pavers, we order by the stamped series code and color run to match your existing floor exactly. Depending on availability, that’s usually 3 to 7 days in Miami. We also work with KraftMaid, Cambria, and Silestone for related bathroom components, so you get one point of contact for the whole job.
