What a Full Bathroom Remodel in Marco Actually Costs and Takes
A full bathroom remodeling project in Marco typically runs $9,000 to $28,000 and takes 3-6 weeks from demo to final walkthrough, depending on whether you’re keeping the same footprint or moving plumbing and walls. That range covers a complete gut-and-rebuild: strip everything to the studs, replace the shower or tub, install new flooring, vanity, lighting, exhaust fan, and fixtures, then finish with paint and trim.

What You’re Really Buying With a Full Remodel
A full bathroom remodel on Marco isn’t a cosmetic refresh. The salt air here punishes bathrooms harder than most homeowners realize until the drywall behind the tile starts softening or the vanity base shows swelling at the bottom edge. What looks like a simple tile-and-paint job often reveals corroded fasteners, compromised backer board, and cast-iron drain lines that predate current code. We scope the job around what we find, not what we hope is there - and that honesty is why our upfront pricing includes a thorough pre-construction inspection before we write any number.
When you compare contractors for a full bathroom remodeling in Marco, three things separate a job that holds up from one that fails early: the waterproofing system behind the tile, the corrosion resistance of every hidden fastener and connector, and whether the exhaust fan is sized and ducted to handle Marco’s humidity load year-round. We spec Schluter or equal membrane systems, stainless or coated fasteners on every rough-in connection, and Panasonic humidity-sensing fans that run until the moisture is actually gone - not just until the timer clicks off. Those three choices add maybe $400-$600 to materials cost and buy a decade of mold-free walls.
Homeowners who are also tackling a larger renovation often pair this with a Bathroom Remodeling in Marco project that spans multiple rooms. In coastal homes, we sometimes find that exterior moisture intrusion - the kind that eventually calls for Roof Repair in Marco - has been slowly feeding wall-cavity humidity that shows up first in a bathroom. If the roof has been patched repeatedly and the bathroom below it keeps smelling musty despite new ventilation, a Roof Replacement & Installation in Marco might be the real fix before we close up the walls.
How We Build a Full Bathroom Remodel, Stage by Stage
Most full bathroom remodeling jobs in Marco follow the same five-stage sequence. Here’s how it works with our crew, and what you’re deciding at each step.
Stage 1: Demo and discovery (Days 1-2). We protect the travel path with floor covering, seal the doorway with dust containment, and strip the room to studs and subfloor. This is where we confirm what’s behind the walls - whether the existing plumbing vent stack is cast iron and cracked, whether the subfloor around the toilet flange has any rot, whether the electrical is grounded properly for modern GFCI requirements. If we find something the estimate didn’t account for, we stop, show you photos and a fixed-price change order, and get approval before touching it. You’re deciding nothing yet - this stage is about exposing the truth of the structure.
Stage 2: Rough-in and layout lock (Days 3-7). Our plumber and electrician relocate supply lines, drain lines, and wiring to match the new fixture layout. This is the point of no return on moving the shower valve, toilet, or vanity location - so we walk you through the final placement on-site with tape on the floor before any pipe gets cut. In Marco, many original bathrooms put the toilet directly in the sightline from the door; shifting it 18 inches changes the whole feel of the room. Rough-in inspection happens here - Collier County requires it before we can cover any wall.
Stage 3: Waterproofing, tile prep, and drywall (Days 8-14). This is the stage that separates a 5-year bathroom from a 20-year bathroom. We apply a full membrane waterproofing system on every wet-wall surface - not just the shower pan - and run it up to the showerhead height at minimum, often to the ceiling in steam-prone Marco bathrooms. Cement backer board gets taped and sealed at every seam. The drywall crew hangs and finishes the non-wet areas, and we set the exhaust fan housing and ducting. You’re choosing grout color and tile layout pattern here - we bring samples and lay out a dry mockup on the floor so you see how the pattern hits at corners and niches.
Stage 4: Tile, trim, and fixtures (Days 15-21). Tile goes in first - floor tile, then shower walls, then any accent or border work. After the grout cures, we install the vanity, countertop, mirror, lighting fixtures, towel bars, toilet, and shower door or curtain rod. The plumber sets the shower trim kit and tests everything under pressure. If you chose a frameless glass enclosure, the glass company measures now and fabricates - that typically adds 5-7 days before final install. This is the stage where the room starts looking finished, and it’s also where we flag anything that doesn’t meet our standard before you ever see it.
Stage 5: Finish and walkthrough (Days 22-28). Paint touch-ups, caulk, final electrical trim-out, and a deep clean. We run the exhaust fan for an hour with a moisture meter in the room to confirm it’s pulling effectively. Our project lead walks you through every surface, every drawer, every valve - if something isn’t right, we fix it before we call the job closed. Your 730-Day Done Right Promise starts the day you sign off, not the day you first call us.
Every stage is documented with photos sent to you, so if you can’t be on-site daily, you still see exactly what’s happening behind the walls.
The Options You’ll Choose Between
A full bathroom remodel involves roughly a dozen material and fixture decisions. Here are the ones that most affect what you pay and how the room holds up on Marco.
- Shower system: acrylic surround vs. tile. A one-piece or multi-piece acrylic surround runs $800-$1,800 and installs in a day. Tile runs $2,500-$6,000 depending on material and layout complexity but gives you full design control and, when waterproofed correctly, lasts longer in humid conditions. Marco homes with original 1960s tile showers that were built with mud-set pans often lasted 40+ years - modern membrane systems match that lifespan.
- Vanity: stock vs. semi-custom. A stock vanity from a big-box supplier lands around $400-$900 and fits standard widths. A semi-custom vanity built to your exact width and finish runs $1,200-$3,000 delivered. The difference matters in Marco’s older homes, where bathroom footprints are often tight and an off-the-shelf 48-inch vanity leaves a 3-inch gap on one side that collects moisture and debris.
- Flooring: porcelain tile vs. luxury vinyl plank. Porcelain tile is the standard for Marco bathrooms - it’s impervious to water, handles the slab-on-grade substrate common in Deltona-era homes, and costs $4-$10 per square foot installed with underlayment. Luxury vinyl plank runs $3-$7 per square foot and feels warmer underfoot, but it’s less forgiving if the slab has moisture vapor transmission issues, which we test for before recommending it.
- Countertop: cultured marble vs. quartz. A cultured marble vanity top with an integrated sink is a clean, seamless option at $300-$700. Quartz runs $600-$1,400 but resists staining and scratching better and matches the look of a higher-end kitchen or Bathroom Remodeling package. For master baths, quartz is the more common choice on Marco at this point.
- Exhaust ventilation: standard vs. humidity-sensing. A basic 50-CFM builder-grade fan costs $40 and moves air. A Panasonic humidity-sensing fan costs $140-$220 and runs until the moisture level in the room actually drops below the mold-growth threshold. Given Marco’s average relative humidity of 74-78% for half the year, this is one of the highest-return upgrades in the entire project. We install these as standard on every full remodel; we won’t spec a fan that can’t keep up with the local climate.
What Full Bathroom Remodeling Costs in Marco, FL
A full bathroom remodeling project in Marco lands between $9,000 and $28,000 for a standard 5×8 to 8×10-foot bathroom taken to the studs. The low end assumes you’re keeping the toilet, sink, and shower in the same locations with builder-grade finishes. The high end reflects relocating plumbing, upgrading to a custom-tile walk-in shower with a frameless glass enclosure, installing a semi-custom vanity with quartz tops, and bringing the electrical up to current code with dedicated circuits.
Here’s what moves the number:
- Plumbing location changes. Moving a toilet, shower drain, or vanity supply line adds $1,200-$3,500 depending on whether we’re cutting into the slab or working in a crawlspace. On Marco, many original bathrooms sit on concrete slab-on-grade, so moving a drain line means saw-cutting, trenching, and re-pouring - that alone can add $2,000+.
- Waterproofing scope. A full Schluter membrane system on all wet walls adds $800-$1,500 over a basic cement-board-and-paint approach. In a coastal environment, this is not the place to save money.
- Existing condition of the subfloor and framing. If we open the floor and find rot around the toilet flange - common in 50-year-old Marco homes - replacing a section of subfloor and possibly sistering a joist adds $400-$1,200.
- Fixture grade. A Delta or Moen builder-grade shower trim kit costs $80-$150. A Kohler or Brizo kit with thermostatic control runs $350-$700. Multiply that across the sink faucet, showerhead, and towel bars, and the fixture package alone can swing $1,000.
- Permit fees. Collier County permit costs for a full bathroom remodel typically run $400-$800 depending on the trade scope. We pull the permit, schedule the inspections, and include the fee in your upfront price - no surprise line items.

What Marco Homes Specifically Do to This Job
The dominant housing stock on Marco is Deltona-era concrete block stucco ranches built in the 1960s and 70s on slab-on-grade foundations. These bathrooms were framed with the materials and standards of their time: cast-iron drain lines that corrode from the inside, copper supply lines that develop pinhole leaks after 50 years of our water chemistry, and wall cavities that were never designed to handle the humidity load of a modern, air-conditioned home sealed tight against the Gulf air. When we open a wall in one of these bathrooms, we expect to find at least some fastener corrosion - and often enough to warrant replacing every screw and bracket that touches the wet wall.
Collier County’s substantial improvement rule is the single biggest cost wildcard on any Marco bathroom project. If your renovation crosses 50% of the structure’s assessed value - and a full bathroom remodel paired with even modest other work can push a 1960s ranch over that line - the county requires the entire structure be brought into compliance with current FEMA flood elevation standards. That can mean lifting the house. We flag this potential at the estimate stage because we have seen too many homeowners get halfway through design only to learn the project triggers a rebuild they didn’t budget for. We don’t want you to be surprised, and we’ll tell you honestly if the numbers suggest the threshold is in play.
Salt air corrodes everything. That’s not a figure of speech on Marco - it’s a daily reality. Every piece of hardware that goes into your bathroom remodel, from the screws holding the backer board to the clips anchoring the vanity to the wall, needs to be stainless or coated for corrosion resistance. We spec hot-dipped galvanized or stainless fasteners on every rough-in, use Quikrete corrosion-inhibiting grout additives in shower pans, and select exhaust fan housings rated for coastal exposure. These are small line items that add maybe $200-$300 across the whole project, and they’re invisible once the walls are closed - but they’re the difference between a bathroom that looks new in year three and one that’s already showing rust streaks on the ceiling.
The teardown-rebuild cycle on Marco also means we work on a mix of original 1960s bathrooms and brand-new elevated construction where the bathroom sits on a plywood subfloor 12 feet above grade. The job changes entirely between those two - slab work on the ground, framed floor work in the air - and our pricing reflects which one you actually have.

Frequently Asked Questions About Full Bathroom Remodeling in Marco
Plan on 3 to 6 weeks from demolition to final walkthrough. A straightforward gut-and-replace with no plumbing relocation runs closer to 3 weeks. Moving the toilet, shower, or vanity, adding custom tile work, or waiting on a frameless glass enclosure pushes it toward 5 or 6 weeks. Permitting and inspection scheduling with Collier County adds 3-7 business days to the front end. Call (844) 638-7249 and we’ll give you a project timeline based on your specific scope.
Yes. Collier County requires permits for any bathroom remodel that involves plumbing, electrical, or structural changes - which a full remodel always does. We pull all required permits, schedule the rough-in and final inspections, and close them out. The permit cost is included in our upfront price. Working without a permit risks a stop-work order and complicates any future home sale when the unpermitted work shows up on the seller’s disclosure.
Yes, and keeping the toilet, sink, and shower in their original locations is the single biggest way to control cost. A same-footprint full bathroom remodel in Marco typically lands in the $9,000-$15,000 range. You still get new tile, a new shower or tub, a new vanity, new flooring, and updated electrical and ventilation - you’re just not paying for slab cutting, drain relocation, or new supply-line rough-ins. We’ll walk you through exactly what’s possible in your existing layout during the free estimate.
Every full bathroom remodeling project is covered by our 730-Day Done Right Promise. If something isn’t right within two full years of your final walkthrough sign-off, we make it right - no deductible, no argument, no fine print. Manufacturer warranties on fixtures, tile, and materials run separately and typically range from 1 year to lifetime depending on the product. We’ll provide all warranty documentation at project close.
It doesn’t change unless the scope changes - and we won’t change the scope without your written approval. Our upfront pricing is built on a detailed pre-construction inspection of your Marco home, so we’re pricing what we can see and what we reasonably expect based on the age and construction type. If we open a wall and find something the estimate didn’t account for, we stop work, show you photos and a fixed-price change order, and wait for your approval. You’re never surprised by a bill. Call (844) 638-7249 for an estimate that reflects the real condition of your home.
