National bathroom cost articles don't help much in Southwest Florida. They blend every kind of project in every part of the country into one average. They also don't account for Florida humidity, wet-area construction or the permit process here.
This guide uses the ranges we publish on our bathroom remodeling page, then explains what moves a project up or down inside them.
The short answer: a guest bath refresh runs $8,000 to $15,000, a primary bathroom remodel runs $20,000 to $40,000, and a full remodel with layout changes runs $40,000 to $75,000 or more. Where your project lands depends mostly on the shower, the tile, the vanity and whether any plumbing moves. Hidden conditions behind the walls are the other big variable, which is why we disclose a 15 percent contingency up front.
Bathroom Remodel Cost by Tier in Southwest Florida
Here are the three tiers side by side.
| Tier | Range | Typical scope | Main cost driver |
|---|---|---|---|
| Guest bath refresh | $8,000 to $15,000 | Same layout and plumbing, with new tile, vanity, fixtures and lighting | What turns up behind the old tile |
| Primary bathroom remodel | $20,000 to $40,000 | Walk-in shower, double vanity and new tile throughout | Shower size and tile selection |
| Full remodel | $40,000 to $75,000+ | Full gut, with layout or plumbing changes and high-end materials | Plumbing moves, structural work and material grade |
Guest Bath Refresh ($8,000 to $15,000)
A guest bath is usually a small room with a tub and shower combination, a toilet and a single vanity. At this tier, you keep the existing layout and plumbing. You get new tile in the shower or tub surround, a new vanity and countertop, updated fixtures, new lighting, a mirror and fresh paint.
Reality check: A guest bath can climb once the walls open up. In some older homes, tile was set directly over drywall with no waterproofing behind it. If that's what we find, the wall has to be rebuilt correctly before new tile goes on, and that work comes out of the contingency.
Primary Bathroom Remodel ($20,000 to $40,000)
This is the tier for a real change. A primary bathroom with room for it can take a walk-in shower, a double vanity, and either a soaking tub or a tub-to-shower conversion.
The scope at this tier includes new tile throughout, a walk-in shower with a waterproofing membrane, a double vanity with a quartz or stone top, new fixtures and lighting, and an exhaust fan vented to the outdoors.
What drives the range: Shower size and tile selection are the biggest variables. A standard walk-in shower with field tile prices very differently from a large curbless shower with large-format porcelain. The vanity (stock or semi-custom) is the next biggest driver.
Full Remodel ($40,000 to $75,000+)
This tier covers a full gut of a large primary bathroom. It also covers a project that moves plumbing, reconfigures the layout, adds heated floors or uses high-end materials. Typical pieces include large-format tile, a curbless shower with a linear drain, a freestanding tub, custom cabinetry and a premium countertop.
What pushes past $75,000: Structural work (removing walls or relocating a door or window), very large showers, full suite additions and top-tier materials such as book-matched stone and specialty designer tile all push a project past this range.
Where a Bathroom Estimate Moves
Tile and the Shower Enclosure
Tile and the shower are where a bathroom estimate moves the most. The tile cost covers more than the material. It includes the labor-intensive installation, the substrate work and the waterproofing underneath.
Tile prices span a wide range, from basic ceramic to large-format porcelain, natural stone and designer tile. Larger formats and detailed patterns also take more labor to set. The floor and walls have to be flatter, and the cuts take longer. We price your actual selections in the estimate rather than quoting a per-square-foot number in advance.
The substrate under the tile matters. The 2023 Florida Building Code, Residential, Section R702.4.2 says: "Materials used as backers for wall tile in tub and shower areas and wall panels in shower areas shall be of materials listed in Table R702.4.2, and installed in accordance with the manufacturer's recommendations." That table lists glass mat gypsum, fiber-reinforced gypsum and two cement-based backer types. We recommend a waterproofing membrane on top of the backer in every tiled shower. Schluter KERDI, Laticrete Hydro Ban and RedGard are common examples.
Vanity and Countertop
Vanities come in three broad grades. Stock vanities come in fixed sizes and suit secondary bathrooms. Semi-custom vanities offer more sizes and finishes, with the top usually priced separately. Custom vanities are built to your exact dimensions.
For countertops, quartz, marble and quartzite each sit at different price points. The Natural Stone Institute's guide to quartzite explains that marble etches from everyday acids like lemon juice or vinegar, while true quartzite does not. It also warns that some stone sold as quartzite is really marble, so ask to test a sample. Size, edge profile and the number of sink cutouts all move the price.
Plumbing Changes
Moving any plumbing (relocating a toilet, changing the shower rough-in or adding a second sink) adds cost, and how much depends on how far things move. On a concrete slab, moving a drain means cutting and patching the slab. Keeping the toilet, vanity and shower rough-ins where they are keeps costs lower.
Florida Details That Add Cost (But Matter)
The right wall board in the right place. Section R702.3.7.1 of the Florida Building Code, Residential, says: "Water-resistant gypsum backing board shall not be used where there will be direct exposure to water, or in areas subject to continuous high humidity." Inside the shower, that means one of the backer materials above, not ordinary drywall.
An exhaust fan that meets code and vents outside. Table M1507.4 of the Florida Building Code, Residential, sets the bathroom minimum as "Mechanical exhaust capacity of 50 cfm intermittent or 20 cfm continuous." Section M1507.2 adds that bathroom exhaust air "shall be exhausted directly to the outdoors." It also says that air "shall not discharge into an attic, crawl space or other areas inside the building."
The duct matters too. Section M1506.2 caps how long an exhaust duct can run, based on the fan's rating and the duct's size and type, with some exceptions. A long run can therefore call for a larger duct.
Ground-fault protection. If the existing bathroom outlets don't have ground-fault (GFCI) protection, a remodel is the time to add it. The building department's inspector has the final word on what your project needs.
Popular Projects and What Drives Their Cost
Tub-to-Shower Conversion
This project removes a rarely used tub and replaces it with a walk-in shower. We cover it in depth in our tub-to-shower conversion guide.
What drives the cost: The cost depends on whether the shower stays inside the old tub footprint or grows, the tile you pick, and the enclosure.
Glass is a meaningful line item on its own. It varies with framed or frameless design, glass thickness, panel size and hardware. A curtain rod costs far less.
Curbless Shower
A curbless (zero-entry) shower needs a floor that slopes toward the drain inside the shower with no curb to step over. Building that slope adds work, which is why curbless showers cost more than a standard walk-in.
Removing the step-over helps anyone who uses a wheelchair or walker. Our guide to aging-in-place bathroom design covers curbless showers and the other details that make a bathroom easier to use for years.
Tile Replacement Only
This means stripping old tile and retiling an existing shower and floor, with no plumbing or vanity work. Tile selection and shower size drive the price. In older homes, the substrate behind the tile can turn out to be drywall, green board or a failing mortar bed. When that happens, the job becomes a substrate rebuild, which is what the contingency is for.
Cost by City in Southwest Florida
Our price does not change by city. A bathroom in Fort Myers, Estero, Bonita Springs or Naples is priced on its scope and selections, not its ZIP code. Only long drive times north of our area move the number.
What does change from place to place is the building department. On Fort Myers Beach and Sanibel, a home can sit in a mapped flood zone, and that can add requirements to a larger remodel. You can look up any address on FEMA's Flood Map Service Center.
The building department for your address enforces the Florida Building Code, and it can add local amendments and its own procedures, so it has the final word on what your project needs.
How to Budget for a Bathroom Remodel
Always Add a 15 Percent Contingency
A bathroom remodel in an older Southwest Florida home can turn up:
- Tile installed over drywall with no backer board and no waterproofing
- Old plumbing with corroded valves that fail when they're touched
- Mold behind a tile wall that looks fine from the outside
- A vanity set over an uneven floor that needs leveling
- Electrical that can't support a heated floor or modern fixtures
We disclose a 15 percent contingency up front so these surprises have a place in the budget before work starts.
Where Not to Cut Corners
- Proper waterproofing. Put a waterproofing membrane under the tile on every shower wall, over one of the backers in Table R702.4.2. Backer board alone is not enough. A membrane costs little compared with tearing out a failed shower later.
- Exhaust ventilation. A fan that meets the code minimum and vents outside, never into the attic, helps keep moisture and mold down. Our guide to remodeling for Florida's humidity covers the materials that hold up in a damp room.
ROI: What You Get Back
Mid-Range Bathroom Remodel ROI
Zonda's 2025 Cost vs. Value Report (published on JLC Online) puts a midrange bath remodel in the South Atlantic region at a job cost of $25,609 and a resale value of $19,273. That's 75.3 percent of the cost recouped at sale.

Resale isn't the only return. A sound shower also avoids the water damage a failing one causes.
Walk-In Shower vs. Tub for Resale
Does removing a tub hurt resale? It depends on who buys in your area. If your primary bath has the only tub in the house, talk to a local realtor about buyers in your neighborhood before converting it.
Getting an Accurate Estimate
What to Prepare Before Calling a Contractor
Rough room and shower dimensions help, and so do photos of the room from each corner, the inside of the shower and the plumbing under the sink. Be specific about what you want to change. "New shower tile" and "remove the tub and build a larger walk-in shower" are very different projects.
Say what you want to keep, because every item you keep is money you don't spend. A ballpark budget also helps us propose the right scope.
What a Good Estimate Includes
A good bathroom remodel estimate is itemized:
- Demo scope (what's coming out)
- Substrate and waterproofing (what goes behind the tile, which is where cheap quotes cut corners)
- Tile and materials (specific products, not vague allowances)
- Plumbing scope (which fixtures, and whether any rough-in work is needed)
- Electrical scope (fan, lighting and GFCI)
- Permits (listed as their own line)
- Labor, payment schedule and timeline
The building department for your address enforces the Florida Building Code. It can add local amendments and its own procedures, so it has the final word on whether your project needs a permit and which inspections apply.
Red Flags in Bathroom Quotes
- Far lower than other quotes. This can mean the waterproofing membrane was left out, the labor is unlicensed, or materials were cut in ways that aren't obvious on paper.
- A lump sum with no itemization. You can't evaluate what you're buying.
- No permit line item. A remodel that touches plumbing or electrical can need a permit. A contractor who plans to skip one leaves you with unpermitted work to explain when you sell.
- A large deposit before work starts. Good contractors tie payments to project milestones.
- No license number. Ask for it, then look it up on the Florida DBPR license search.
