What a Full Bathroom Remodel in Sanibel Actually Costs and How Long It Takes
A full bathroom remodeling job in Sanibel typically runs between $9,000 and $28,000, with most mid-range projects landing around $14,000 to $18,000. That gets you a complete gut-and-rebuild: demo down to the studs, new plumbing fixtures and supply lines where they already sit, updated electrical, moisture-resistant drywall or cement board, a new tub or shower pan, waterproofing, tile work, vanity, toilet, lighting, and exhaust fan. A straightforward full remodel on an existing footprint takes our crew 10 to 16 working days from demo to final walkthrough.

How We Take a Sanibel Bathroom From Gutted to Finished
When people ask what full bathroom remodeling actually looks like day to day, they’re usually trying to figure out how long they’ll be without that bathroom and when they need to have their selections locked in. Here’s the sequence we follow, and it’s the same one Derek Hollenbeck’s crew runs on Sanibel jobs week in and week out.
Stage 1: Demolition and Rough-In Inspection Prep (Days 1-2)
We protect the travel path with floor covering and zip-wall dust barriers, then remove everything: tile, drywall, vanity, tub or shower, toilet, flooring, and any rotted subfloor. If we find water damage behind the walls, which isn’t uncommon in older Sanibel beach cottages that sat through decades of humidity and salt air before Ian, we stop and show you exactly what we found before we proceed. By the end of day two, the room is a clean shell with exposed framing, and our plumber and electrician have marked out any fixture relocations you’ve approved. This is also the point where we call in the rough-in inspection with the City of Sanibel’s building department, which operates its own permit queue independent of Lee County.
Stage 2: Rough Plumbing, Electrical, and Shower Pan (Days 3-5)
Once the rough-in passes inspection, the trades move fast. We run new PEX supply lines, set the new shower valve and tub filler, wire in the new lighting circuits and GFCI-protected outlets, and install the exhaust fan ductwork. If you chose a custom tile shower pan, we pour the pre-slope mortar bed, lay the PVC pan liner, and flood-test it for 24 hours before the inspector signs off. This is the stage where any decision you haven’t made on fixture placement needs to happen: moving a drain even six inches can add a day and a thousand dollars because it means opening the floor and re-plumbing the waste line. A full bathroom remodeling project that keeps the toilet, tub, and vanity in the same locations stays on the lower end of that $9,000-$28,000 range.
Stage 3: Wall Board, Waterproofing, and Tile (Days 6-10)
We hang cement backer board on every wet wall, tape and mud the seams, then apply a full liquid-applied waterproofing membrane over the entire shower enclosure up to the showerhead height. On Sanibel projects, we insist on this step because barrier-island humidity finds every shortcut. Tile work usually takes three to four days depending on the size of the shower, whether you’re running tile to the ceiling, and the complexity of the pattern. Floor tile goes in next, then grout, then a minimum 24-hour cure before anyone walks on it. We protect the finished tile with Ram Board while the rest of the job wraps up.
Stage 4: Trim-Out, Vanity, and Fixtures (Days 11-13)
This is when the room starts looking like a bathroom again. Our plumber sets the toilet, connects the vanity faucet and shower trim kit, and installs the tub drain assembly. The electrician hangs the light fixtures, installs the GFCI outlets, and wires the exhaust fan timer or humidity switch. The vanity goes in, and if you’ve chosen a stone top with an undermount sink, the fabricator measures and cuts the slab offsite before our crew drops it into place. Mirror, towel bars, and shower door follow, assuming the glass enclosure measurements were taken earlier when the tile was complete and the walls were final.
Stage 5: Final Inspection and Walkthrough (Day 14-16)
We schedule the City of Sanibel final inspection, which checks the plumbing, electrical, and any structural work against the permit set. Our crew chief walks the room with you, tests every fixture and drain, and makes a punch list of anything that needs attention. Once the inspector signs the permit card and you’re satisfied, the room is yours. Every full bathroom remodel we do in Sanibel carries our 730-Day Done Right Promise: if something isn’t right, we come back and make it right, no argument, no charge.
The Choices That Shape the Cost and the Finished Room
A full bathroom remodeling project puts a lot of decisions on your plate, and each one shifts the final number. Here are the big ones, with the trade-offs laid out plainly.
- Shower vs. tub vs. both. A standard alcove tub with a tiled surround runs $3,500-$5,500 installed. A walk-in shower with a custom tile pan and frameless glass enclosure starts around $6,500 and can climb past $9,000 with floor-to-ceiling tile, a bench, and a niche. Keeping the tub where it sits is the budget-friendly move; converting a tub to a walk-in shower adds plumbing and waterproofing labor.
- Tile selection and coverage. Ceramic wall tile starts around $4 per square foot for the material; large-format porcelain runs $8-$14 per square foot; natural stone like marble or travertine starts at $12 and can hit $30. Running tile to the ceiling adds 30-40% more tile area and labor versus a standard wainscot height, and it’s a decision that’s purely aesthetic.
- Vanity construction and top material. A stock 48-inch vanity with a cultured marble top from a home center lands around $800-$1,200 for the unit. A semi-custom solid-wood vanity with a Kohler sink and a quartz or Cambria top runs $2,500-$4,000. The jump is in the dovetail joinery, the soft-close hardware, and the stone fabrication, and it’s the kind of upgrade that holds up to Sanibel humidity better than MDF.
- Plumbing fixture grade. A builder-grade shower trim kit costs $80-$150 and functions fine. A pressure-balanced Kohler or Delta trim in brushed nickel or matte black runs $300-$600 and includes ceramic disc cartridges that last longer, plus finish plating that resists the salt-air corrosion we deal with on this barrier island. The difference over a decade of daily use is noticeable.
- Flooring and waterproofing upgrades. Porcelain floor tile over a cement board underlayment is the standard recommendation for Sanibel bathrooms, where humidity and occasional flooding are facts of life. Vinyl plank flooring costs less up front but won’t survive a storm surge. The waterproofing membrane under the shower tile is not a place to cut corners: we apply a full liquid membrane because a failed shower pan on a Sanibel home means mold inside the wall cavity within weeks.
What Full Bathroom Remodeling Costs in Sanibel, FL
A full bathroom remodeling project in Sanibel runs $9,000 to $28,000, and where your job lands inside that band depends on a handful of specific variables. A $9,000 remodel is a straightforward job: one bathroom, roughly 40 to 60 square feet, no plumbing relocation, ceramic tile at standard height, a stock vanity, and a standard alcove tub with a tiled surround. A $28,000 remodel is a larger master bath with a custom walk-in shower, floor-to-ceiling porcelain or natural stone, a custom double vanity with a quartz top, relocated plumbing and electrical, possibly a new window or skylight, and permits pulled through Sanibel’s own building department.
The five things that push the number up are square footage, whether you move the toilet or tub drain, the material grade you choose for tile and stone, the complexity of the shower enclosure, and the age of the house. Older Sanibel homes, especially those 1950s-70s low-slab cottages that survived Ian or were partially rebuilt, often have cast-iron drain lines and cloth-wrapped wiring that need to be brought up to current code, and that work is behind the walls before we lay a single tile. A written quote from us includes the permit fees, the material allowances, the fixture specifications, and the labor broken down by phase so you see exactly what you’re paying for.
If you’re also thinking about a broader renovation, a full bathroom remodel is often part of a Bathroom Remodeling in Sanibel project that touches multiple rooms, and we can scope both at the same walkthrough. Call (844) 638-7249 and we’ll schedule a free estimate with real numbers on paper.
What Sanibel Homes Specifically Do to This Job
Full bathroom remodeling on Sanibel comes with conditions that simply don’t apply across the causeway in Fort Myers. The city runs its own building department, and permits for any bathroom remodel that opens a wall, touches plumbing, or alters the electrical system go through Sanibel’s permit counter, not Lee County. That adds a few days of lead time that a mainland contractor might not budget for, and you want a crew that already knows the inspection cadence. Our bathroom remodeling crew schedules around that queue as a matter of routine.
The housing stock tells the rest of the story. A lot of the pre-Ian Sanibel inventory was 1950s to 1970s low-slab beach cottages and ranch homes, and the ones that survived the 10-to-15-foot storm surge often took water inside the walls. When we open a bathroom in one of these houses, we’re looking for legacy water damage, corroded cast-iron drain pipes, and framing that absorbed salt and moisture for decades before Ian ever showed up. Post-Ian reconstruction has converted many of those lots to elevated homes on concrete pilings, which means the bathrooms we’re building now sit on framed subfloors rather than slab-on-grade, with all-new rough plumbing running through the floor joists inside the conditioned envelope. It’s a fundamentally different installation than a slab bath, and it changes how we route drains and vents.
Coastal conditions drive material choices here more than in any mainland Sanibel service area. The salt air eats standard steel fasteners and unplated hardware in a few years, so we use hot-dipped galvanized or stainless screws on every backer board, every vanity bracket, and every accessory mount. Impact-rated windows are code minimum if the bathroom has an exterior window. And because every load of tile, drywall, and lumber comes across the Sanibel Causeway, we coordinate deliveries to avoid the worst of the tourist-season traffic that can turn a 45-minute round trip into two hours. None of this is theoretical; it’s how we’ve run bathroom jobs on Sanibel through the entire post-Ian rebuild cycle.
Some homeowners tying a full bathroom remodel into a larger reconstruction also have us look at exterior work that took storm damage. We’ve had clients schedule a Roof Repair in Sanibel on the same project, or even a full Roof Replacement & Installation in Sanibel, so the whole property moves forward at once. It keeps the permit timeline consolidated and the trades coordinated.

Frequently Asked Questions About Full Bathroom Remodeling in Sanibel
Most full bathroom remodeling projects in Sanibel take 10 to 16 working days from the first day of demolition to the final walkthrough. The timeline stretches when we need to relocate plumbing drains, when custom stone fabrication has a longer lead time, or when the City of Sanibel inspection schedule creates gaps between the rough-in and the close-up stages. We give you a day-by-day schedule at the estimate so you know when the bathroom will be usable again. If you’re planning around guests or a rental calendar, call (844) 638-7249 and we’ll work backward from your date.
Yes. Sanibel requires a building permit for any bathroom remodel that involves plumbing, electrical, or structural changes, which a full gut-and-rebuild always does. The permit goes through the City of Sanibel Building Department, not Lee County, and the cost of the permit is included in our written estimate. We pull the permit, schedule the inspections, and make sure the job passes before we collect the final payment.
Yes, and that’s the single biggest cost-control decision you’ll make. Moving a toilet drain means cutting into the floor, re-routing the waste line, and possibly altering the vent stack, which can add $1,500 to $3,000 to the total depending on what’s below the bathroom. If the existing layout works for you, keeping the fixtures in place keeps the project closer to the $9,000 to $14,000 range. During the estimate walkthrough, Derek Hollenbeck will show you exactly what staying in footprint saves versus what a layout change buys you.
Every full bathroom remodeling job we complete is covered by our 730-Day Done Right Promise. That means two full years. If tile cracks, grout fails, a valve leaks, or anything we installed isn’t performing, we come back and make it right at our cost. The fixture manufacturers carry their own warranties on top of that. The promise is straightforward: it’s right, or we fix it.
A full bathroom remodel is a complete gut: we take the room down to the studs and rebuild everything: plumbing, electrical, waterproofing, tile, fixtures, and finishes. Replacing just a tub or a vanity is a single-fixture swap that leaves the surrounding tile, drywall, and subfloor untouched. Full bathroom remodeling makes sense when the room has water damage, when you want to change the layout, or when the finishes are dated and you want a cohesive new design from floor to ceiling. If all you need is a new tub with tile, that’s a smaller job, and we can scope it during the same walkthrough.
