We’ll walk your job site, flag the code issues upfront, and build a schedule that accounts for Bay Harbor Islands logistics from day one.
Why Groundwork Construction Co. of South Florida Is Bay Harbor Islands’s Preferred Bathroom Remodeling Company
We’ve worked on homes from East Broadview Circle to West Bay Harbor Drive, and the pattern is consistent: mid-century construction, original cast-iron plumbing, and bathrooms that need more than cosmetic help. Raymond Estevez, our owner, has directed projects on the islands long enough to know which inspectors flag BFE compliance gaps and which material deliveries need buffer days built around Broad Causeway traffic.
Our reputation here is built on showing up with solutions, not surprises. Homeowners in Bay Harbor Islands call us back because we spot the slab conditions and corrosion issues before demolition starts, not after. We’re licensed and insured, and our estimates are free and itemized.
Response time matters on an island with one access point. We typically schedule Bay Harbor Islands consultations within 48 hours, and we don’t outsource plumbing or tile work to separate crews who don’t know the local code layers. One contractor, every phase.
Our Bathroom Remodeling Services in Bay Harbor Islands
Full Bathroom Remodeling
A full gut-and-rebuild in Bay Harbor Islands almost always reveals something the original 1950s or 1960s builder didn’t anticipate: a concrete slab that sits too low for current flood elevation, galvanized supply lines pinholed from decades of use, or salt-corroded vent stacks. Our Bathroom Remodeling team handles the complete sequence: demolition, rough plumbing to code, BFE-compliant floor work, waterproofing, tile, fixtures, and finish carpentry. You choose the brand, we handle the build.
Walk-In Shower Installation
Walk-in shower installation in Bay Harbor Islands runs $4,500-$12,000. The island’s hard water and salt air make material selection critical. We specify Schluter or Laticrete waterproofing membranes as baseline, not upgrades, and we source frameless glass hardware from suppliers who use 316 stainless or aluminum with anodized finishes that won’t pit. In flood-zone homes, we often need to raise or reconfigure the floor assembly before the pan goes in. Our crew recently handled a bathroom remodel on East Center Court, where the builder-grade Kohler faucet had corroded at the base from salt air and the original 1950s cast-iron tub sat directly on a concrete slab. We had to chisel out the slab to lower the new shower pan and meet BFE requirements, then finished with a Schluter waterproofing system and a Cambria quartz vanity top that won’t show the island’s hard water spots.
Tub-to-Shower Conversion
Converting a tub to a shower in Bay Harbor Islands costs $3,500-$10,000. Many island homes have those heavy cast-iron tubs set into small bathrooms where the slab and drain location don’t match modern shower dimensions. We handle the concrete cutting, drain relocation, and any BFE-triggered floor modifications. For clients expanding into ADUs or guest quarters, we can coordinate with our prefab partners - Mighty Buildings or Boxabl - to match interior finishes across the property. Built to spec, not to convenience.
Vanities, Tile & Fixtures
Bay Harbor Islands’ humidity and salt exposure punish cheap particleboard vanities and standard chrome hardware. We work with 50+ recognized industry brands across cabinetry, countertops, and fixtures, giving you material choices across multiple price tiers. Cambria, Silestone, and Caesarstone for countertops. KraftMaid and Wellborn for vanities that won’t swell at the joints. For tile, we favor porcelain over ceramic in wet areas and specify epoxy grout in shower enclosures where the marine air never really dries out.
Small Bathroom Remodels
A small bathroom remodel in Bay Harbor Islands ranges from $5,000-$12,000. Space is tight on these original platted lots, and every inch counts. We design for the constraints: wall-hung vanities that free floor area, recessed niches instead of protruding shelves, and curbless showers where BFE compliance allows. The single-bridge access means we schedule material deliveries precisely - no laydown yard, no overflow storage. Sequencing discipline matters here more than on the mainland.

Trusted Brands We Service in Bay Harbor Islands
Groundwork partners with 50+ industry-leading brands so you’re never locked into a single vendor’s product line. For Bay Harbor Islands bathrooms, that means Cambria quartz vanities that resist hard-water spotting, Schluter waterproofing systems rated for continuous moisture exposure, and stainless or hot-dipped galvanized fasteners that won’t corrode behind your tile in the salt air. We maintain supplier relationships across South Florida, which keeps lead times reasonable even when the Broad Causeway backs up. From driveway to roofline, one accountable team sources every material.
Common Bathroom Remodeling Problems We See in Bay Harbor Islands Homes
- Corroded fasteners and brackets. Using non-stainless or non-hot-dipped galvanized fasteners and brackets, which corrode within a few years in Bay Harbor Islands’ salt-laden air and compromise the structure behind the tile. We see this on original construction and on cut-rate remodels done without marine-grade hardware.
- Flood-code violations on plumbing changes. Ignoring FEMA AE/VE flood compliance when altering plumbing rough-ins or lowering floors, leading to failed inspections and costly rework after the fact. Essentially the entire town falls within FEMA AE or VE flood zones, so virtually any substantial improvement triggers Base Flood Elevation compliance.
- Wrong wallboard in wet areas. Specifying standard gypsum drywall or green board instead of cement board or waterproofing membrane in the shower area, which wicks moisture and mildew in the humid marine climate. We tear out a lot of “recently remodeled” showers with this exact failure.
- Slab conditions hiding in plain sight. Original 1950s-1970s slabs in Bay Harbor Islands often sit below current BFE, meaning a straightforward fixture swap can balloon into a floor-raising project if the contractor doesn’t verify elevations before quoting.

FAQs - Bathroom Remodeling in Bay Harbor Islands
The salt-laden air surrounding Biscayne Bay accelerates corrosion of standard chrome, brass, and unprotected steel fixtures by a factor of years compared to inland Miami-Dade locations. We specify 316 stainless, solid brass with PVD finishes, or powder-coated aluminum for hardware, and we recommend quartz or solid-surface countertops that don’t show etching from airborne salt and hard water. Call (844) 665-0162 if you want us to assess what’s salvageable and what needs replacement.
Yes, Miami-Dade County requires permits for any plumbing, electrical, or structural work, and Bay Harbor Islands’ FEMA flood-zone status means bathroom projects altering rough-ins or floor elevations also trigger BFE compliance review. We pull permits as part of our standard process and handle the elevation certificates and inspector coordination. Most Bay Harbor Islands bathroom permits take 2-4 weeks depending on county backlog.
Sometimes, but rarely without complications. In Bay Harbor Islands, lowering a slab often exposes you to the water table or drops the finished floor below BFE, which triggers fill, stem-wall, or raised-floor work to bring it back into compliance. We evaluate the slab elevation, soil conditions, and flood-zone designation before recommending any floor modification. Our East Center Court project is a typical example: the slab had to be chiseled and rebuilt, not simply lowered.
Porcelain tile with epoxy grout on a cement-board or foam-board substrate with a liquid-applied or sheet waterproofing membrane. We favor Schluter-Kerdi or Laticrete Hydro Ban systems in Bay Harbor Islands because they handle the constant humidity and occasional storm-driven moisture penetration better than traditional methods. Avoid green board or standard drywall behind tile in this environment - we’ve replaced too many failed showers that used it.
Three to six weeks for most projects, with the longer end applying when BFE compliance requires floor reconstruction or when material deliveries are delayed by Broad Causeway access restrictions. We build buffer days into every Bay Harbor Islands schedule that wouldn’t be necessary on the mainland. A simple vanity-and-tile refresh with no plumbing moves might finish in two weeks. Call (844) 665-0162 for a timeline based on your specific scope.
