Unilock Bathroom Remodeling: The Miami Owner’s Guide
Unilock bathroom remodeling in Miami typically runs $10,620 – $33,040 installed, depending on bathroom size, material grade, and how much plumbing needs to move. If you’ve got a Unilock paver patio or walkway outside a bathroom that’s failing, or you’re planning a bathroom remodel that ties into existing Unilock hardscaping, we’ll match the materials and do the whole job under one written price. Most Miami homeowners call us because water is getting somewhere it shouldn’t, or because a Unilock surface outside a bathroom entrance has shifted and now pitches water back toward the house instead of away from it.
This page covers what fails, what it costs to fix, and whether the work falls under a bathroom remodel or a paver repair, because in South Florida those two things overlap more than people expect.
Which Unilock Models This Applies To
In bathroom work, Unilock products show up most often as exterior hardscaping that connects to a bathroom addition or a ground-floor bath that opens to a patio. The common lines we work with in Miami are the Unilock Beacon Hill flagstone, Mattoni plank pavers, and the Estate Wall system when a bathroom addition creates a grade change that needs retaining. Each line has different thickness specs, and that matters more than people think.
Here’s a compatibility gotcha we run into regularly: Unilock pavers come in 60mm and 80mm thicknesses, and the 60mm products are rated for pedestrian use only. If a paver surface outside a bathroom entrance also carries a golf cart or a mower, you need the 80mm line or a concrete base thick enough to make up the difference. We’ve seen 60mm pavers crack within two years in Miami when the base was thin and the paver carried more weight than it was spec’d for. The model name is stamped on the underside of most Unilock pavers, but with sun and sand wear, that stamp fades. We go by measurement and pattern, not just the label.
For interior bathroom remodeling, Unilock itself doesn’t make tile or fixtures. What we do is coordinate the interior remodel with existing Unilock hardscape outside, matching paver color and joint lines so the threshold from bath to patio reads as one continuous surface. When an owner is committed to the Unilock aesthetic outside, we treat the bathroom-to-outdoor transition as one design problem, not two separate jobs.
Styles & brands we work with
Signs Your Unilock Bathroom Remodeling Is Failing
- Water staining at the exterior threshold. The seal between paver and sill has failed, and Miami’s afternoon downpours push water under the door. The fix is usually re-sloping the paver field and replacing the threshold flashing, not just caulking the gap.
- Pavers have sunk or tilted near the bathroom wall. The base underneath has washed out, often because a downspout or AC condensate line drains too close to the foundation. Water under a paver in Miami’s sandy soil moves fast and takes the base with it.
- Efflorescence (white chalky film) on pavers or interior tile near the door. Moisture is wicking through the substrate. It’s rarely a structural emergency, but it tells you water is sitting where it shouldn’t, and over a Miami summer that turns into mold or shifting.
- Interior tile cracking in a bathroom that opens to a paver patio. The slab has moved, and the crack pattern travels from outside to inside. This is the one that means the job is no longer a simple paver repair; it’s a rebuild of the affected floor section with proper base compaction.
- Musty smell in a ground-floor bath with a patio door. The paver slope has reversed, and water is pooling against the exterior wall. In older Miami homes, especially in Coconut Grove, the original slab often wasn’t poured with enough fall away from the house.
Replacement Cost & What’s Included
For a full bathroom remodel in Miami, the honest range is $10,620 – $33,040. A small bath refresh with a new vanity, toilet, and paint starts around $5,900. A gut remodel with a walk-in shower, new plumbing rough-in, and frameless glass runs $14,160 – $33,040 depending on fixture grade and whether we’re moving supply lines or drains. If the job also includes repairing or re-laying Unilock pavers outside the bathroom, add $4,130 – $12,980 for a paver patio repair depending on square footage and base condition.
Every price we write includes labor, materials, debris hauling, and the written guarantee. We don’t do allowances that get “adjusted” later. The number on the written estimate is the number on the invoice. Trevor Nash doesn’t hand out a range and then discover problems after demo day. If we find something behind the wall that changes the scope, we stop, we tell you, we put the new number in writing before we touch another stud.
DIY or Call Us?
You can safely check a few things: clean the paver joints near the bathroom threshold, verify your downspouts discharge at least four feet from the foundation, and look for standing water after a hard rain. Those don’t require tools beyond a hose and your eyes.
What you shouldn’t do is pull up pavers and re-compact a base without a plate compactor and a laser level, or try to re-slope a paver field against a bathroom wall. Get the slope wrong by even a quarter inch over four feet and you’ve directed water at your own foundation. Same goes for interior work: any job that touches plumbing rough-in, waterproofing, or load-bearing framing is a job for a licensed crew. Call (850) 988-7559 and we’ll walk the job with you before you commit to anything.

AfterWill the Price Change Once the Work Starts?
No. The written price we hand you before any work starts is the number on the invoice. If demo uncovers something hidden, like rotted framing behind a shower wall or a base that was never properly compacted, we stop work, show you what we found, and give you a new written number before we go further. We don’t change orders on a handshake.
Do You Pull the Permits?
Yes. Any bathroom remodel in Miami that touches plumbing, electrical, or structural work gets permitted through the city, and we handle the paperwork, the inspections, and the sign-offs. We also pull permits for paver work when site drainage changes are involved. If a contractor tells you a permit isn’t needed for a full bath remodel, that’s a sign to call someone else.
How Long Does the Job Take?
A small bath refresh takes five to eight working days. A full gut remodel with new plumbing and tile runs three to six weeks. Paver repair outside the bathroom adds two to five days depending on how much base needs to be removed and replaced. We’ll give you a defined arrival window before work starts, and a written schedule so you know what’s happening each day. Call (850) 988-7559 for a project timeline specific to your home.
Do You Stock Unilock Parts and Materials?
We keep common Unilock paver sizes and edge restraints on hand for repairs, and we source the specific line and color you already have installed when we need to match an existing field. For interior bathroom work, we stock and install KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Moen fixtures. If you need a single course of Unilock pavers matched to an existing patio, bring us a photo and a measurement, and we can usually tell you within one visit whether we have it or need to order it. Call (850) 988-7559 and we’ll check our inventory while you’re on the phone.
Key Takeaways
- Unilock bathroom remodeling in Miami runs $10,620 – $33,040 for a full remodel, less for a refresh.
- Exterior Unilock pavers tied to a bathroom threshold fail most often from water in the base, not the paver itself.
- 60mm Unilock pavers are pedestrian-rated; heavier traffic needs the 80mm line or a thicker base.
- We give a written price before any work starts, and that number is the number on the invoice.
- Our 365-Day Done Right Promise: if something we built fails inside a year, we come back and fix it at no charge, in writing, on every job.
