Bathroom Remodeling in Key Biscayne

Waterproofing matters more at sea level.

The original Key Biscayne house shipped with one bathroom, and it was not generous. Seventy years later, owners in the village core and Biscayne Key Estates are carving real primary suites out of bedroom wings, while waterfront homes on Mashta Island and Harbor Point get the full treatment: freestanding tubs, book-matched stone, showers with more plumbing than the original house had in total. In the condo towers, baths from the 70s and 80s are being gutted to the slab, where the tile is usually the youngest thing in the wall.

Bathroom work is plumbing and electrical work, which means permits and inspections through the Village of Key Biscayne's Building, Zoning and Planning Department — no exceptions for small footprints. In the towers, tying into a building riser takes association approval and a scheduled water shut-down for your stack, which we coordinate with management rather than spring on your neighbors. Florida's post-Surfside milestone-inspection era has made island boards rightly attentive to what happens inside walls and slabs, so our submittals arrive complete: drawings, insurance, licensing, and a schedule the building can hold us to.

This is the trade where PGX is least willing to negotiate. Every shower gets a full waterproofing assembly — pan, membrane, flood test — because on an island with this much humidity, a shortcut behind the tile becomes a demolition order in five years. A written scope fixes the fixtures, stone, and glass before we open a wall; a supervisor checks the site daily; and the same licensed team (Lic. CGC1539072) answers for the job from first sketch to warranty call. It is a small room. That is exactly why the details are the whole project.

What's included

What we build behind the glass.

Five ways Key Biscayne owners rebuild their baths — each one permitted, flood-tested, and finished under daily supervision.

01

Spare rooms into primary suites

Turning a spare bedroom or an oversized closet into a true primary bath, with the structural and plumbing work fully permitted.

02

Showers that hold their water

Curbless entries, linear drains, and heavy glass set on properly sloped, flood-tested pans — the details that keep water where it belongs.

03

Freestanding tubs, floor-mounted fillers

Sculptural tubs set against stone or glass, with floor-mounted fillers roughed in precisely, so nobody guesses where the valve lands.

04

Tile set over full waterproofing

Porcelain, marble, and mosaic installed over full waterproofing assemblies, with layouts planned slab to ceiling before the first cut.

05

Baths built around riser shut-downs

Gut renovations in the island's towers, coordinated with association approvals, riser shut-downs, and elevator schedules so neighbors barely notice.

FAQ

Straight answers.

Do I need a permit for a bathroom remodel in Key Biscayne?
Yes. Bathroom remodels involve plumbing and electrical work, which the Village of Key Biscayne permits and inspects regardless of the room's size. Your contractor also has to be registered with the Village before applying. It adds a little process, and it is the reason a finished PGX bathroom comes with an inspection record instead of an open question when you refinance or sell.
Can you renovate a bathroom in one of the older condo towers?
Yes, and we do it with the building's cooperation rather than around it. Older Key Biscayne towers often have original branch valves and risers, so tying in new plumbing means association approval and a scheduled water shut-down for your stack. We coordinate the notice with management, replace what is worn at the connection while the wall is open, and follow the building's rules on hours, elevators, and protection without drama.
How do you keep a new bathroom from growing mold on an island this humid?
By treating waterproofing and ventilation as the project, not accessories to the tile. Every PGX shower gets a complete waterproofing assembly with a flood test before finishes go on, exhaust ventilation is sized and ducted properly, and we detail the transitions — niches, benches, curbs — where failures actually start. Key Biscayne humidity punishes shortcuts behind walls. Our answer is not a special product; it is refusing to skip steps nobody would see us skip.
How long does a primary bathroom remodel take?
A full gut of a primary bath generally runs several weeks of construction once materials are in hand, plus lead time for stone, fixtures, and custom glass — glass is templated after tile, so it always trails the finish work. Condo association work windows can add calendar time. We sequence orders before demolition so the room is torn up once, briefly, instead of twice, indefinitely.
What does a high-end bathroom remodel cost on the Key?
Bathrooms concentrate cost per square foot: stone, glass, plumbing fixtures, and waterproofing all live in a small footprint, and moving fixtures adds real plumbing scope. Ranges vary widely with finish level, so we would rather walk your actual bathroom and write a fixed scope than recite a number that fits nobody. With PGX the figure you approve is itemized, allowances are yours to steer, and the price does not drift once signed.
