Master Bathroom Remodel Miami: 2026 Costs, Layouts & Permits
Last updated: October 2026
What goes into a master bathroom remodel in Miami?
A master bathroom remodel is usually more than new tile. Most projects touch the shower, the vanity wall, lighting, ventilation, and often the layout itself. In Miami, two more things shape the plan: humidity that never takes a season off, and the many homes that are condos, where your bathroom floor is a neighbor's ceiling.
If you already know your scope, you can compare licensed Miami bathroom remodelers and get itemized quotes. If you're still choosing a layout and a budget, the sections below walk through each decision in the order contractors will ask about it.
Popular master bathroom layouts in Miami
Most Miami master bath redesigns combine two or three of these moves. Each one changes cost, permits, and schedule in its own way.
Walk-in or curbless shower
A large walk-in shower with frameless glass is a top request in Florida master baths. A curbless version removes the step entirely.
Check first: The floor must be recessed or built up so water slopes to the drain. On a concrete slab or in a high-rise, confirm this is possible before you commit.
Double vanity
Two sinks with storage between them, often a floating vanity with a quartz top and LED lighting.
Check first: A second sink adds a drain and supply lines, and new outlets or lights add electrical work. Both mean permits.
Removing the tub
Swapping a rarely used tub for a bigger shower frees floor space and makes the room easier to use as you age.
Check first: If it's the only tub in the house, weigh young kids and future buyers before you take it out.
Freestanding tub
A freestanding soaking tub works as the focal point in a larger master bath, usually paired with a separate shower.
Check first: It needs open floor space around it and its own faucet location. On a wood-framed upper floor, ask whether the floor can carry a filled tub.
How much does a master bathroom remodel cost in Miami?
Miami runs above the Florida average for bathroom work. These 2026 estimates match the ranges on our Miami and statewide bathroom pages.
| Project level | Miami estimate | Florida statewide | Typical scope |
|---|---|---|---|
| Mid-range master bath | $22,000–$35,000 | $18,000–$28,000 | Walk-in shower, double vanity, quartz counters, upgraded tile, better ventilation |
| High-end / luxury remodel | $40,000–$60,000+ | $30,000–$50,000+ | Curbless wet room, freestanding tub, custom tile, premium fixtures, layout changes |
Estimates only. Your price depends on room size, finishes, and how much plumbing moves.
Moving plumbing is the biggest single cost driver, so keeping the toilet, shower drain, and sinks where they are saves the most. Condo projects add cost for protecting common areas and meeting association rules. Waterproofing is the one line item not to trim.

How long does a master bathroom remodel take?
- 1
Design and quotes. Settle the layout first so every contractor prices the same scope.
- 2
Permit review. In the City of Miami, small residential projects that qualify can get same-day walk-through review. Larger projects can take one to three months.
- 3
Ordering. Order the vanity, shower glass, and specialty tile early. Lead times often set the start date.
- 4
Construction. A typical remodel takes 3–6 weeks. Condo projects may take longer because of building rules and logistics.
- 5
Inspections. Inspectors approve each phase of permitted work, so build inspection dates into the schedule.
Do you need a permit for a master bathroom remodel in Miami?
Usually, yes. Miami-Dade County's home renovation permit brochure says interior work such as knocking down a wall or altering or repairing the electrical or plumbing system needs a permit. Painting and wallpapering do not.
- Who issues it: each municipality in Miami-Dade has its own building official. In unincorporated Miami-Dade, the county building department issues permits.
- City of Miami: the city's interior remodel permit page calls for separate sub-permits for electrical, mechanical, and plumbing work, and residential plans signed and sealed by an architect or engineer.
- Review time: residential projects under ten plan pages, under $75,000, and under 500 sq ft can use a same-day walk-through. Larger projects can take one to three months.
- What's exempt: the City of Miami's list of work exempt from a permit includes like-for-like sink swaps and exhaust fan replacement. Cabinet and countertop swaps are exempt only in single-family homes and duplexes, and only when no plumbing, wiring, or load-bearing walls change.
- Who pulls it: only licensed contractors or owner-builders may obtain a permit in Miami-Dade. Under section 489.113, Florida Statutes, a general or residential contractor must subcontract plumbing and electrical work unless they hold that trade license.
Before you sign, confirm every license on the state database. Our guide on how to check a Florida contractor license takes a few minutes.
Condo vs. single-family master bath
| Factor | Condo | Single-family home |
|---|---|---|
| Permit exemptions | In the City of Miami, the flooring and cabinet exemptions apply only to single-family homes and duplexes. | Some surface swaps are exempt. Plumbing and electrical changes still need permits. |
| Building rules | Read your association's renovation rules on approvals, work hours, and plumbing tie-ins before you collect quotes. | No association, unless your community has an HOA with its own rules. |
| Moving drains | In many buildings, drain lines run through the slab toward the unit below, which limits relocation. | More flexible, though a slab-on-grade home may need concrete cut for new drain lines. |
| Leak risk | A leak can damage the unit below, so waterproofing the full wet area matters. | A leak damages your own subfloor, framing, and finishes. |
In a condo, ask each contractor how they will protect the unit below during demolition and how they will waterproof the whole wet area, not just the shower pan.
Which materials hold up to Miami humidity?
- An exhaust fan sized for the room and ducted outside, ideally on a humidity sensor or timer so it keeps running after showers.
- A waterproofing membrane behind the shower tile and across the shower floor. In a condo, extend it under the entire wet area.
- Porcelain or ceramic tile. Large-format tile cuts down on grout lines that trap moisture.
- Cement board or mold-resistant board in wet areas, not standard drywall.
- Quartz countertops, which resist moisture and don't need sealing.
- Plywood vanity boxes and LED lighting, which both hold up better in a humid room.
Aging-in-place features to build in now
A master bath remodel is the easiest time to add features you may need later, because the walls and floor are already open.
- A curbless shower entry with slip-resistant floor tile.
- Wood blocking inside the walls so grab bars can go anywhere later.
- A built-in shower bench and a handheld shower on a slide bar.
- Lever-style faucets and door handles.
- A comfort-height toilet.
- A wider doorway and bright, even lighting with a switch at the entry.
What to compare in master bath quotes
- The same scope on every quote: layout, tile area, fixture list, and who pulls the permits.
- Allowances for tile, fixtures, and the vanity, so upgrades don't surprise you later.
- The waterproofing method by product name, and the warranty that covers it.
- License numbers for the contractor and for the plumbing and electrical subcontractors.
- The payment schedule. Under section 489.126, Florida Statutes, a contractor who takes more than 10% up front must apply for permits within 30 days and start work within 90 days after permits are issued, unless there is just cause or you agree in writing to a longer period.

Frequently asked questions
How much does a master bathroom remodel cost in Miami?
Estimates run about $22,000–$35,000 for a mid-range master bath and $40,000–$60,000+ for a high-end remodel. Moving plumbing, condo logistics, and custom tile push a project toward the top of the range.
How long does a master bathroom remodel take in Miami?
A typical remodel takes 3–6 weeks of construction, and condo projects may take longer. Add permit review time: the City of Miami offers same-day walk-through review for small residential projects that qualify, while larger projects can take one to three months.
Do I need a permit to remodel my master bathroom in Miami?
Yes, if you alter or repair plumbing or electrical, or remove a wall. A like-for-like sink swap or replacing an exhaust fan is on the City of Miami's exempt list. Each municipality in Miami-Dade has its own building official, so your contractor should confirm the rules for your address.
Should I remove the bathtub from my master bathroom?
Many owners trade a rarely used tub for a larger walk-in shower. If it's the only tub in the home, think about young children and future buyers first. Converting a tub to a shower usually means changing the drain, which is plumbing work that needs a permit in Miami-Dade.
Can I get a curbless shower in a Miami condo?
Often, but not always. The floor has to be recessed or built up so water slopes to the drain, and in a high-rise the slab and the unit below limit what can change. Have your contractor check before you commit to the design.
What aging-in-place features should a master bath include?
The most useful are a curbless shower with slip-resistant tile, wood blocking in the walls for future grab bars, a shower bench, a handheld shower, lever handles, a comfort-height toilet, and a wider doorway.
