Most Florida homeowners ask the same handful of things before they tear out a bathroom: how long it takes, what it will cost, whether a permit is needed, and how to keep moisture from ruining the new work. This bathroom remodeling FAQ answers those questions plainly, in the order they usually come up, so you can walk into a contractor meeting already knowing what to ask and what a good answer sounds like.
We have grouped the questions by project stage instead of listing them at random. Start with planning and budget, move into the technical work that happens behind the walls, and finish with scheduling and daily life during construction. A dozen quick-hit answers also sit at the bottom of the page for anyone who wants a fast reference.
Planning questions to settle first
Do I need a designer, a contractor, or both? For a straightforward update that keeps the toilet, tub and vanity where they are, a licensed general contractor who handles selections can carry the whole job. Once you start relocating fixtures, widening a doorway or merging a closet into the room, someone needs to produce a measured plan, and many contractors provide that as part of design and build.
Should I keep the current layout? Keeping the drain and supply locations is the most reliable way to control spending. Moving a toilet means rerouting a large drain line with proper fall, which on a slab foundation can mean cutting concrete. A shower that shifts a few feet often needs a new drain, a new vent connection and new framing. None of that is impossible, it simply belongs in the budget conversation early.
How do I pick finishes without stalling the project? Make selections before demolition, not during it. Tile, valves, glass and vanities all carry lead times, and a missing piece can stop a crew for days. Ask for a selections sheet listing each item, its finish, quantity and order status.

What actually moves the price
We avoid quoting numbers in an article because every bathroom is different, but the forces behind a quote are predictable. Our Florida bathroom remodel cost breakdown goes into more detail, and the main drivers are listed here:
- Scope: cosmetic refresh, full gut, or a layout change with new plumbing
- Tile area and pattern complexity, since large-format and herringbone layouts take longer to set
- Shower type, including curbless entries that require recessing or sloping the subfloor
- Glass: frameless panels cost more than framed doors and need precise measurements after tile
- Hidden conditions such as rotted subfloor, corroded supply lines or old wiring that must be brought up to code
- Fixture grade, from builder-line faucets to thermostatic valves and wall-hung toilets
Should I hold back a contingency? Yes. Older Florida homes in particular can hide water damage under a tub or behind a shower wall. A reserve set aside before work starts keeps a surprise from turning into a stalled job. Any extra work should be written up as a change order with a price before it proceeds.
Bathroom remodeling FAQ: behind the walls
What is a waterproof membrane and why does it matter? Tile and grout are not waterproof. Water passes through grout lines and reaches whatever is underneath. A properly installed membrane, either a liquid-applied coating or a bonded sheet system, sits between the tile and the backer board so water is directed to the drain instead of soaking into framing.
What is a flood test? After the shower pan and membrane are installed, the drain is plugged and the pan is filled with water, then left for a period while the crew checks for any drop in level or signs of leaking. Doing this before tile goes down is cheap insurance; finding a leak after tile is set is not.
How much slope does a shower floor need? The floor must slope to drain consistently so water never sits in corners. With a linear drain, the slope runs in one direction; with a center drain, it falls from all sides. Your installer should confirm slope with a level before tile and again after.
Does ventilation really matter in Florida? More than almost anywhere. Humid outdoor air plus daily showers is a recipe for mildew. A properly sized exhaust fan, ducted to the exterior rather than into the attic, is basic. Our article on how to prevent mold in Florida bathrooms covers fan sizing, timers and humidity sensors.
Permits, licensing and inspections
Does a bathroom remodel need a permit? Replacing a vanity top or swapping a faucet usually does not. Moving plumbing, adding circuits, altering framing or changing the footprint generally does, under the Florida Building Code and your local building department's rules. A reputable contractor pulls the permit and schedules inspections so the work is documented when you sell.
How do I confirm a contractor is licensed? Search their name or license number on the Florida DBPR license lookup. Confirm the license is active, then ask for a certificate of insurance listing general liability and workers' compensation. Our page on working with a licensed and insured contractor explains what each document protects.
Scheduling and living through the work
How long will I be without the bathroom? That depends on scope, inspections and whether materials are on site before demolition. A cosmetic update moves faster than a gut renovation, and a layout change adds rough-in and inspection time. Ask for a written schedule that shows each phase and which inspections fall between them.
Will there be dust? Some, yes. Good crews hang plastic barriers, protect floors along the path to the room and cover return vents nearby. Tile cutting is best done outdoors or with wet saws to keep airborne dust down.
Who should I call when something looks wrong? One person. A project with a single accountable point of contact avoids the finger-pointing that happens when the plumber, tile setter and electrician each answer to someone different. Ask at the start who that person is, how quickly they return calls, and how decisions get confirmed in writing.
What happens at the end? Expect a walkthrough with a punch list of small items such as caulk touch-ups, a door that needs adjusting or a missing outlet cover. The final inspection should be passed and signed off, and you should receive warranty details and care instructions for grout, glass and fixtures.
Settle the layout and selections before demolition, insist on a flood-tested shower pan, and confirm the license on the DBPR site. Those three steps prevent most of the problems homeowners call us about.

Frequently Asked Questions
In most cases, yes. If the home has a second bathroom, daily life continues with some noise and dust during working hours. In a single-bath home, plan ahead by asking the contractor to sequence the work so the toilet is out of service for as short a stretch as possible, or arrange to stay elsewhere during the heaviest phase.
There is no rule requiring one, but many buyers with young children still like having at least one tub in the house. If you are converting the only tub to a shower, think about who might buy the home later. When another bathroom keeps a tub, removing one from the primary bath is generally a safe choice.
Cement board or foam board panels designed for wet areas are common choices behind shower tile. Regular drywall, even moisture-resistant types, does not belong inside the shower enclosure. Whatever board is used, it still needs a waterproof membrane or must be part of a complete manufacturer system with sealed seams and fasteners.
Grout type affects how much sealing and cleaning you will do. Standard cement grout needs periodic sealing. Urethane and epoxy grouts resist staining and moisture better but take more skill to install. Ask the installer what they recommend for your tile size and how the joints should be maintained after the job.
A timer or humidity-sensing switch helps because most people turn the fan off as soon as they leave the room, while moisture lingers for much longer. Letting the fan run after a shower clears steam from the ceiling and walls. Make sure the fan vents to the exterior, not into the attic space.
A curbed shower has a raised lip that keeps water inside the enclosure. A curbless shower sits flush with the bathroom floor, which helps accessibility and looks clean, but it requires the shower area to be lowered or the floor carefully sloped so water still reaches the drain. That extra structural work often adds time.
They are less common here but some homeowners like them for cool winter mornings, especially over tile. Electric mats under the tile need a dedicated circuit and a thermostat. They should be installed and tested before tile is set. If comfort is the goal, they can be worth discussing, but they are rarely a priority.
Tiling over old tile is sometimes done on floors that are flat and well bonded, but it raises the floor height and hides any problems underneath. In showers it is rarely a good idea, because the existing waterproofing cannot be checked. Most contractors prefer to remove old tile and inspect the substrate.
A useful quote lists demolition, framing, plumbing, electrical, waterproofing, tile, fixtures, glass, painting, permits and cleanup as separate lines, along with who supplies each material. It should state the payment schedule and how change orders are priced. Vague one-line quotes make it hard to compare bids fairly.
If the walls are open anyway, replacing an older valve is usually wise. A modern pressure-balancing or thermostatic valve helps prevent scalding when someone flushes a toilet elsewhere in the house. It is far easier to change the valve during demolition than after new tile is in place.
Use a glass panel instead of a shower curtain, carry the same floor tile into the shower, choose a wall-mounted or floating vanity, and add good layered lighting. Larger tiles with fewer grout lines also reduce visual clutter. Mirrors and lighter colors help, though layout matters more than color.
Interior bathroom work can happen any time of year. Some homeowners prefer to avoid peak hurricane months in case supply delays or storm cleanup pull crews away, but a well-planned project with materials ordered early can proceed in any season. Scheduling around holidays and house guests is often the bigger concern.
