Fast, Reliable Bathroom Remodeling Across Key Biscayne
A full bathroom remodel in Key Biscayne typically runs $9,000 – $28,000, and the work is phased around village permit sign-offs, not just crew availability. Key Biscayne is a barrier island with one road in and out, so every material delivery, dumpster swap, and inspection walk-through gets scheduled around the Rickenbacker Causeway and village permit windows. That’s the reality we plan for on every job here. Call (254) 272-5876 and we’ll walk you through a real number for your bathroom before you commit to anything.
We know Key Biscayne’s housing stock: 1960s and 1970s island condos on concrete slabs, newer builds near the beach, and the occasional single-family home off Crandon Boulevard. Each one has different plumbing, different waterproofing needs, and different permit triggers. Our Bathroom Remodeling team has torn open enough of these bathrooms to know what’s behind the walls before we quote the job.

Shower Remodel in Key Biscayne
A Shower Remodel in Key Biscayne means tearing out an existing shower or tub-shower combo and rebuilding it with new waterproofing, valves, tile, glass, and trim. This is the most common job we do on the island because so many older condos still have original fiberglass pans and single-handle valves that have been corroding in salt air for 40 years. A shower remodel here lands in the $4,500 – $12,000 range depending on size, condition of the subfloor, and whether you’re replacing the valve, the drain, or both.
What Gets Replaced and When
In a typical Key Biscayne shower remodel, we pull the old pan and backer board down to the studs. If the original drain is cast iron under a concrete slab, that’s the point where the job gets bigger, and we’ll show you the allowance in writing before we cut anything. In 1970s condos near the Key Biscayne K-8 Center, we regularly find mud-set beds over slabs. It’s not a surprise to us, and it shouldn’t be a surprise to you at invoice time.
Glass enclosures, tile, grout, and fixtures are chosen up front. We spec Kohler and Moen valves and trim as standard, because cheap valves fail fast in this humidity. You pick the tile; we waterproof to Miami-Dade code before the first tile goes up.
Walk-In Shower Conversion
If you’re done stepping over a tub wall, a walk-in shower conversion replaces the tub footprint with a curbless or low-curb shower. In Key Biscayne, this usually means reworking the drain location, a new pan, and a full waterproofing assembly. It lands between $4,500 and $12,000 depending on whether we’re moving plumbing or keeping the drain where it is.
Tub to Shower Conversion in Key Biscayne
A Tub to Shower Conversion in Key Biscayne takes an existing tub and replaces it with a walk-in shower, typically without changing the bathroom’s footprint. For homeowners in older island condos, this is the fastest way to get a safer, more open bathroom without moving walls. The price runs $3,500 – $10,000, and the main variables are drain location, subfloor condition, and whether the old tub is sitting on a mud-set bed.
Why Condos Need This More Than Houses
Most Key Biscayne condos weren’t designed for aging in place. A tub wall is a fall risk, and the bathrooms are small. Converting to a shower opens up the room visually and physically, and we can frame a curbless entry that works with the existing slab. We did exactly this for a client in a 1970s unit near the Key Biscayne K-8 Center. The original tub sat on a mud-set bed over a concrete slab. Our tech broke out the old pan, re-ran the rough-in to a center drain with Kohler fixtures, and framed the curbless entry in front of the inspector. Because the change order was signed before we touched the shower valve, the client knew the exact tile allowance and draw schedule before demo started.
What Moves the Price
The biggest cost swings come from what’s under the tub. If the subfloor is solid and the drain is in the right place, the job is straightforward. If we find a corroded cast-iron drain or water damage around the flange, that’s additional rough-in work within the $3,500 – $10,000 range. We write the allowance into your quote so you see it before the hammer comes out.
Trusted Brands We Service in Key Biscayne
We stock and install fixtures and materials from Kohler, Moen, KraftMaid, Wellborn, Cambria, and Caesarstone. That matters on a barrier island because lead times and delivery windows are tight. When we quote a Key Biscayne bathroom remodel, we’re quoting real parts from real suppliers, not whatever’s on a shelf at the big-box store. For tile underlayment and waterproofing substrates we use Schluter edge trim (the metal strip that waterproofs where your tile meets the floor) and Schluter membranes, because coastal humidity punishes shortcuts. If you’re doing your own research on materials, ask us about Sakrete floor patch and leveling products we use for slab prep work under shower pans.

AfterCommon Bathroom Remodeling Problems We See in Key Biscayne Homes
- Cast-iron drains under concrete slabs. Island condos built in the 1960s and 1970s often have original cast-iron waste lines that have been degrading in salt air for half a century. When we open the floor for a shower pan, we find them, and the rough-in scope changes on the spot.
- Missing or incomplete permits on older units. Some Key Biscayne owners discover they have open permits or unpermitted work from a previous owner. That forces a stop-work until the village and Miami-Dade County sign off, which pushes the punch list past the draw schedule.
- Corroded shower valves and cabinet hinges. Salt air and 80% humidity eat cheap metal fast. Homeowners who spec builder-grade fixtures end up replacing them within a few years. We set Kohler and Moen as the floor, not the upgrade.
- Mud-set tub beds over slabs. Older tubs in Key Biscayne weren’t set in mortar like modern units. They’re often set in a thick mud bed, which means more demo, more debris, and more planning for dumpster and delivery windows on the causeway.

FAQs About Bathroom Remodeling in Key Biscayne
Yes, for nearly every bathroom remodel in Key Biscayne, FL. Any work that touches plumbing, electrical, or structural elements requires a permit from the village and Miami-Dade County. Your best move is to call (254) 272-5876 and we’ll tell you exactly which permits apply to your specific scope.
Most Key Biscayne bathroom remodels take 2 to 4 weeks from demo to final inspection. The timeline is driven by permit sign-off days and inspection scheduling, not just crew hours. On a barrier island, you also have to work around delivery windows and the Rickenbacker Causeway, which adds a day or two to material moves.
A bathroom remodel in Key Biscayne runs $9,000 – $28,000. Walk-in showers land between $4,500 and $12,000, tub-to-shower conversions run $3,500 – $10,000, and a vanity install is $800 – $3,000. Everything is written in your quote before work starts. Call (254) 272-5876 for an exact number.
In older Key Biscayne bathrooms, you’ll typically find cast-iron drains, mud-set tub beds over concrete slabs, and sometimes water-damaged substrate from decades of humidity. If you have a 1960s or 1970s island condo, expect some level of rough-in work when you open the floor. We price that allowance into the quote so it’s not a surprise.
No. A bathroom remodel is planned construction work, not an emergency repair. We don’t promise same-day remodels or rush demo on a five-figure job, because that’s how mistakes get made and inspections get failed. What we do promise is a written price, a real calendar, and a schedule we actually stick to. Call (254) 272-5876 to get your project scoped correctly from day one.
