AfterFast, Reliable Bathroom Remodeling Across Key Biscayne
A bathroom remodel in Key Biscayne runs $9,000 – $28,000, and the biggest cost driver on the island is the same thing that makes the place beautiful: salt air on every side and a single causeway between your front door and every material delivery. We’re Penhallow Remodeling, and we plan around both. Our crews cross the Rickenbacker Causeway every week, we know the condo board rules along Crandon Boulevard, and we know what Miami-Dade’s High Velocity Hurricane Zone code means for a bathroom that has an exterior wall. Call (936) 259-2607 and we’ll walk you through it – written price first, always.
Why Penhallow Remodeling Is Key Biscayne’s Preferred Bathroom Remodeling Company
Key Biscayne homeowners tell us the same thing over and over: they’ve been burned by a contractor who quoted a mainland price, then “discovered” that the tub-to-shower conversion needed impact-rated glazing on the bathroom window, or that the wall cavity behind the tile was full of salt-pitted fasteners from forty years of Bay breeze. We don’t discover those things on day three. We assume them on day one, because every Key Biscayne job requires them.
Our Bathroom Remodeling team prices Key Biscayne work with the island’s actual conditions in mind: HVHZ wind-load requirements on any exterior wall, marine-grade hardware in every rough-in, and a delivery schedule that accounts for the Rickenbacker Causeway. That means the written number you get before we start is the number on the invoice when we finish. No change order because a drawbridge delayed the vanity. No surprise because the inspector flagged non-compliant fasteners. Trevor Nash runs our jobs to the Kingswell standard, and he’s the one you’ll talk to if something isn’t right.
The 365-Day Done Right Promise backs every project in writing. If a threshold settles, a valve leaks, or grout cracks inside the guarantee period, we come back and fix it at no charge. Simple as that.
Small Bathroom Remodel in Key Biscayne
A Small Bathroom Remodel in Key Biscayne typically runs $5,000 – $12,000, and on this island it’s rarely a purely aesthetic job. Most of the small baths we see are in 1960s – 1970s condos along Crandon Boulevard or single-family homes on the interior streets, and they share two problems: original cast-iron plumbing that’s corroding from salt-heavy humidity, and wall cavities that were never built to today’s moisture standards. When we open one up, we usually find exactly what the 40-year recertification reports are flagging all over the island.
Working With an Existing Footprint
Small bathrooms in Key Biscayne condos are not getting bigger. The building shell is fixed, the plumbing stacks are where they are, and the condo association has rules about moving wet walls. What we do well is make a 5×8 or 5×9 space work harder: curbless shower pans that don’t eat floor space, wall-hung vanities that open up the visual floor, and recessed niches that get shampoo bottles off the shower sill without a bulky caddy.
Moisture and Salt Remediation First
Before we set a single tile, we check what’s behind the old one. On Key Biscayne, that often means replacing corroded fasteners, re-securing backup framing, and installing cement board substrate (the moisture-resistant layer behind your tile) with hot-dip galvanized screws. Skipping this step is the cheapest way to get a bathroom that looks new for two years and fails inspection on year three.
Shower Remodel in Key Biscayne
A Shower Remodel in Key Biscayne starts around $3,000 for a straightforward replacement and runs up to $12,000 for a full walk-in shower installation with frameless glass and a custom pan. The island-specific piece is this: if your shower sits on an exterior wall – common in the oceanfront high-rises and the older single-family homes – any window in that shower must meet Miami-Dade NOA impact standards. A mainland contractor might not even look. We check first, because we’ve seen inspectors fail a finished tile job over a non-rated window sitting in the wet zone.
Walk-In Showers and Tub-to-Shower Conversions
Most Key Biscayne clients want the tub gone. In the condos especially, a walk-in shower with a low-threshold entry makes the room feel twice its actual size and is a smart aging-in-place move for homeowners planning to stay. Tub-to-shower conversions run $3,500 – $10,000 depending on whether we’re moving the drain, adding grab blocking, or dealing with an exterior wall that needs an impact-rated window. We quote it all in writing before any demo starts.
Frameless Glass and Hardware That Holds Up
Frameless shower enclosures are the finish every Key Biscayne homeowner asks for, and they’re right to. But the clips and hinges that hold that glass have to fight salt air from Biscayne Bay on one side and the Atlantic on the other. We specify marine-grade stainless hardware, not the plated stuff that pits in eighteen months. Cambria and Silestone shower surrounds carry their own warranty alongside ours, and Kohler valves and Moen trims give us the parts availability that keeps a punch list short even when a delivery crosses the causeway late.
Trusted Brands We Service in Key Biscayne
Because Key Biscayne is an island with one bridge, we can’t fix a materials problem by “running over to the yard real quick.” The yard is a causeway crossing and a state park corridor away. That’s why we stock common Key Biscayne failure points – marine-grade fasteners, PVC trim, cement board, and valve cartridges from Moen and Kohler – in our Miami (South FL) staging office, so a same-week repair doesn’t become a two-week wait. The brands we install are the ones that stand behind their product with a warranty that matches ours: Cambria and Silestone quartz, Kohler and Moen fixtures, and prep materials from Sakrete and Abodu for pans and backing systems.
Common Bathroom Remodeling Problems We See in Key Biscayne Homes
- Salt-corroded wall cavities. Biscayne Bay on the west, the Atlantic on the east – Key Biscayne gets salt spray from basically every wind direction. We regularly find Simpson ties and fasteners rusted to powder behind tile that still looks fine from the outside. That’s a structural problem hiding as a cosmetic one.
- Non-compliant bathroom windows. If your bathroom is on an exterior wall – common in the Crandon Boulevard condo towers – the glazing has to be Miami-Dade NOA impact-rated. A cheap bid that skips this gets flagged at inspection and voids your wind-mitigation documentation.
- Rushed waterproofing. In a climate where the air itself is damp and salty, a thin coat of roll-on membrane over a cement board seam is not enough. We see failed pan liners and tented tiles in showers that were “redone” five years ago. The fix is a full tear-out, not a patch.
- Change orders triggered by causeway delays. A delivered vanity that sat on the mainland an extra day because of a drawbridge opening turns into a labor change order when the tile setter shows up and has nothing to set around. We schedule Key Biscayne deliveries with causeway reality built into the timeline, so the number doesn’t move.

FAQs About Bathroom Remodeling in Key Biscayne
Yes, if the bathroom includes an exterior wall or any exterior glazing. Because Key Biscayne sits in a High Velocity Hurricane Zone, Miami-Dade County requires that any replaced window or door in a bathroom exterior wall meet NOA impact and wind-load standards. A compliant quote includes that testing documentation. A cheap bid leaves it out and you’ll find out at inspection or, worse, at insurance renewal when you can’t get wind-mitigation credit. Call (936) 259-2607 and we’ll tell you what your specific project needs.
The causeway is the reason. Every sheet of cement board, every cabinet, every dumpster hauls across a two-lane bridge through a state park corridor – and there’s no alternate route if a drawbridge opens or a traffic incident blocks the causeway. Contractors who know Key Biscayne build that logistics time into the price and the schedule. Contractors who don’t eat it, then change-order you for it. Our quotes account for it up front, in the written number.
Yes, when the work affects an exterior wall. If we rebuild a bathroom on an exterior wall with the right HVHZ impact-rated products, the wind-mitigation documentation our work generates goes into your file. After a storm, that documentation supports a compliant claim. Without it, an insurer may deny a claim on the basis that the opening wasn’t properly protected. We file the paperwork with every job where it applies.
A Key Biscayne quote should name the marine-grade fasteners and Simpson ties, the Miami-Dade NOA-rated window or wall panel if it’s an exterior wall, the cement board substrate, and the delivery logistics across the Rickenbacker Causeway. A cheap bid skips all of that. It quotes mainland hardware, skips the rated glazing, and hopes the inspector doesn’t look. Ours lists each line so you know exactly what you’re paying for before we start.
Most full bathroom remodels here run three to five weeks, plus a few days’ buffer for causeway delays. Demolition, rough-in, waterproofing, tile, and finish each take roughly a week, but materials deliveries and dumpster hauls depend on the Rickenbacker. We schedule those moves for off-peak drawbridge windows and build a realistic buffer into the timeline so we’re not making promises we can’t keep. You’ll get that schedule in writing with your estimate, not as a verbal guess.
