A full bathroom remodel in Key Largo typically runs $9,000-$28,000, with small bathroom remodels landing between $5,000-$12,000 and walk-in shower installations starting around $4,500.

We’re Barrett & Sons Construction, and we’ve been doing this work since 1998. If you want the real story on salt-air corrosion, Monroe County permits, and why your 1970s bathroom may hide more than old tile, call (877) 610-1318 and you’ll get a live person, not a voicemail.
Why Barrett & Sons Construction Is Key Largo’s Preferred Bathroom Remodeling Company
Tom Barrett started this company 29 years ago, and his sons run the crews today. When a Bathroom Remodeling job in Key Largo needs attention, you’re not getting a rotating cast of subcontractors. You’re getting the Barrett name showing up at your door. Crews are background-checked and uniformed, and Tom publishes his license number, his address, and his name. Look it up before you sign anything. We think you should.
Key Largo customers ask us hard questions, and they deserve straight answers. Does the bathroom need flood elevation certification? Will the county ROGO permit process delay the start date? Those are fair questions, and they’re exactly the ones a mainland contractor might wave off. We don’t wave anything off. Written change orders, written allowances, permits pulled, inspections signed. That’s how we’ve kept our reputation intact from the 33037 zip code down to the canals off Card Sound Road.
Our main scheduling office sits in South Florida, but the crews serving Key Largo live and work right here in the Upper Keys. That matters when a supplier delivers the wrong vanity or a shower pan shows up cracked. We fix the problem locally, not from three counties away.
Our Bathroom Remodeling Services in Key Largo
Full Bathroom Remodeling
A full gut and rebuild in Key Largo usually means opening walls on a home that’s been dealing with 30 or 40 years of humid, salty air. We remove everything to the studs, address any corroded plumbing connections we find, then rebuild with materials rated for this environment. Think porcelain tile, marine-grade plywood behind the drywall, and stainless steel fasteners as the baseline. A complete remodel in Key Largo generally lands between $9,000 and $28,000, and every change to that number arrives in writing before work proceeds.

Walk-In Showers & Shower Remodeling
Walk-in showers are the most requested bathroom upgrade we see in Key Largo, especially in the 1960s-to-1980s concrete block homes that dominate neighborhoods off US-1. Many of these homes still have the original fiberglass tub-shower combo from when they were built. We tear those out and replace them with curbless, low-threshold showers finished in large-format tile or solid surface. In Key Largo, walk-in shower installation runs $4,500-$12,000, with frameless glass enclosures adding to the top end.

Tub-to-Shower Conversion
If you’re aging in place in Key Largo, or you’re tired of stepping over a tub wall every morning, a tub-to-shower conversion makes good sense. We demo the old tub, adjust the drain location if needed, waterproof the surround, and install a shower base with real tile or a solid composite wall system. The salt air here eats through cheap metal fasteners fast, so we spec hot-dipped galvanized or stainless hardware even where you’ll never see it. Tub-to-shower conversions in Key Largo typically cost $3,500-$10,000.

Vanities, Tile & Fixtures
Sometimes the shower is fine but the vanity is falling apart, the tile grout has failed, or the fixtures are pitted from years of Keys humidity. We replace vanities, lay floor and wall tile, set new toilets and faucets, and upgrade lighting and exhaust ventilation. A bathroom vanity installation in Key Largo generally runs $800-$3,000. We also stock common replacement parts locally so a broken trim piece doesn’t stall your project for a week. And when humidity lingers, a proper exhaust fan is not a luxury. It’s how you keep mold out of your new bathroom.

Trusted Brands We Service in Key Largo
We install materials you can look up, not mystery brands off the back of a van. In Key Largo bathrooms, we lean on names like Quikrete for shower pan bases and bedding mortar, products that hold up under constant moisture and salt exposure. For tile and stone work, we work with manufacturers whose products have proven themselves in coastal applications. If you need pavers for an outdoor shower deck or a hardscape surround, we also carry lines from Oldcastle and Techo-Bloc through our related Bathroom Remodeling in Key Largo hardscape work. We keep fast-moving parts stocked for Key Largo customers, which means less waiting when a shower valve, tub spout, or drain assembly needs replacing mid-project.
Common Bathroom Remodeling Problems We See in Key Largo Homes
- Corroded plumbing connections inside walls. Years of salt air and humidity eat brass and steel fittings. We regularly find pitted shut-off valves and corroded trap assemblies when we open a Key Largo bathroom wall, even in homes less than 20 years old.
- Failed waterproofing behind old tile. Many pre-1990s Key Largo bathrooms were built with green board behind the tile instead of cement board or a modern membrane. Once the grout fails, moisture migrates into the wall cavity and the framing starts to degrade.
- Subfloor rot near tubs and toilets. Between high humidity and occasional plumbing leaks, wood subfloor rot is common, especially in stilt homes where the bathroom sits over open air and any leak finds the plywood quickly.
- Undersized exhaust ventilation. A bathroom with no exhaust fan, or one vented into the attic instead of outside, is a mold incubator in Key Largo’s climate. We upgrade ventilation on nearly every remodel we do in the 33037 area.
Pricing for Bathroom Remodeling in Key Largo, FL

What moves the price in Key Largo? The big driver is whether your home needs structural work to pass Monroe County’s HVHZ wind code and flood elevation review. Homes in the AE and VE flood zones often need engineering certification on bathroom remodels that touch exterior walls, plumbing rough-ins, or subfloor framing. That’s a step most mainland contractors never deal with, and it adds cost. We put it all in writing before we start. Every allowance, every scope item, every change order. No surprises at the end. Call (877) 610-1318 for a free, itemized estimate. We also offer a Free Second Opinion on Any Written Estimate. Bring us another contractor’s number and we’ll tell you honestly where it stands.

FAQs - Bathroom Remodeling in Key Largo
A bathroom remodel in Key Largo costs $9,000-$28,000 for a full job, $5,000-$12,000 for a small bathroom, and $4,500-$12,000 for a walk-in shower installation. The wide range reflects the condition of your home, whether you’re in a 1960s concrete block house or a newer stilt home, and how much structural and flood-code work the county requires. Call (877) 610-1318 for an exact quote. Estimates are free, and we put every number in writing before work starts.
Most bathroom remodels in Key Largo take two to six weeks from demo to final inspection. Jobs that require engineering review for Monroe County flood and wind compliance can add a couple weeks at the front end, depending on the ROGO permit allocation and the county’s current review queue. We give you a written timeline at the start, and we update it in writing if the scope changes. No silent delays.
Yes. We work throughout the 33037 ZIP code, including Stillwright Point, Largo Sound, Anglers Park, and the canal-front communities off Card Sound Road and Ocean Bay Drive. Whether your home is on a piling foundation near the water or slab-on-grade on the bay side, we know what the county will require before we open a wall. Call (877) 610-1318 and tell us where you are. No trip charge inside the county.
Yes, we pull permits and pass inspections on every eligible bathroom remodel in Key Largo. Monroe County’s ROGO system, flood elevation rules, and HVHZ wind code make bathroom remodels here more involved than on the mainland. A contractor who says permits are optional in Key Largo is not doing you any favors. The inspector works for you, not for us. That’s why we like having him on the job.
Only if you change the scope, and only in writing. In Key Largo, hidden conditions like rotted subfloor or corroded plumbing can surface once walls come down. If that happens, we document what we found, show it to you, and give you a written change order before any new work happens. An allowance that isn’t on paper is a surprise waiting for a date. We don’t do surprises. We also back every completed remodel with our 90-Day Done Right Promise. If it’s not done right, Tom comes back and makes it right, one call.
