Bathroom Remodeling in Miami: Costs, Process, and Permits

Of every room in a Miami home, the bathroom is the least forgiving. Behind the tile, it's a sealed system fighting constant moisture, and in this climate a remodel that skips real waterproofing and ventilation doesn't just look dated in a few years — it grows mold and rots the wall behind it. Done right, a bathroom is one of the highest-return spaces you can renovate, and the room buyers scrutinize most. Endless Life Design builds bathrooms to last in South Florida's humidity: as a licensed Florida general contractor with in-house engineering, we handle design, the plumbing and electrical permits, and construction from start to finish. Call (305) 680-3283 to begin.
What a Bathroom Remodel Costs in Miami
Cost tracks closely with size, fixture quality, and whether you move plumbing. These are realistic 2026 ranges across South Florida:
Powder room or secondary bath — new vanity, toilet, fixtures, tile, and lighting: $12,000 to $30,000.
Primary bathroom — full remodel with new shower, tub, double vanity, tile, and an updated layout: $35,000 to $90,000.
Luxury primary suite — custom wet room, freestanding soaking tub, premium stone, heated floors, and smart fixtures: $90,000 and up.
What moves the number most: relocating the toilet, shower, or plumbing stack; converting a tub to a curbless walk-in shower; the tile and slab you select; custom frameless glass; and whether the walls come down to the studs. After one consultation we give you a precise, itemized quote — not a number guessed over the phone.
Why Miami Bathrooms Are Built Differently
A bathroom is the one room where Miami's climate is completely unforgiving. Waterproofing is everything. Behind beautiful tile sits a system that has to keep water out of the wall for decades. We install proper waterproofing membranes, sloped substrates, and sealed assemblies so moisture never reaches the framing — the step budget remodels cut, and the reason so many South Florida showers fail early.
Ventilation and materials make or break it. In our humidity, an undersized exhaust fan invites mold no matter how good the tile looks. We size ventilation correctly, specify mold- and moisture-resistant materials, marine-grade and stainless fixtures that resist corrosion in salt air, and porcelain or properly sealed stone built for constant moisture. And because Miami-Dade is a High-Velocity Hurricane Zone, any new bathroom window must be NOA-approved and impact-rated.
The Endless Life Design Process
A bathroom remodel done right in Miami follows a clear, code-compliant path:
Consultation and design — we plan the layout around how you actually use the space.
Licensed sealed plans — our in-house engineers draw the plumbing and electrical plans your permit requires, so nothing stalls at the county.
We pull the permit — we file and manage it through approval.
Demolition and rough-in — plumbing and electrical relocation, followed by inspection.
Waterproofing and tile — membranes, sloping, and sealed assemblies before a single tile goes up.
Fixtures, glass, and finishes — installed to the Royal Custom Construction standard, then a final inspection.
Most bathroom remodels run 4 to 8 weeks depending on scope, tile and slab lead times, and inspection scheduling — generally faster than a kitchen. We give you a real timeline up front and keep you posted at every stage.
We Handle the Permit — You Don't
Moving a toilet, relocating a shower drain, or adding a circuit for heated floors all require permits and inspections, and Miami-Dade, Broward, and Palm Beach each run their own departments and rules.
Endless Life Design works inside those systems every day. We don't send you to a county website — we file complete submissions the first time, coordinate every inspection, and secure approvals so the work keeps moving. Our Government Permit Processing Service ($4,500) can also be engaged on its own if you already have plans and just need a licensed firm to push them through. Call (305) 680-3283 and we'll tell you exactly what your project needs.
Design Styles We Build
Your bathroom should feel like the rest of your home, whether that's a serene spa retreat or a bold statement suite. We design and build across the full range — modern spa, contemporary, transitional, Mediterranean, minimalist, and custom Royal styles — from a clean wet room in a Brickell condo to a marble-clad primary suite in a Coral Gables estate.
Walk-In Showers, Wet Rooms, and Aging in Place
Two requests come up constantly in South Florida: converting a tub into a curbless walk-in shower, and building bathrooms that stay safe and comfortable at every age. We design frameless walk-in showers and full wet rooms with proper slope and drainage, and we build in grab bars, comfort-height fixtures, and zero-threshold entries when you want a space that lasts for the long term — without ever looking clinical.
Materials That Last in South Florida Bathrooms
We steer you toward selections that perform in constant moisture:
Tile and slab: porcelain for showers and floors, properly sealed quartzite or quartz for vanity tops, and natural stone where the design calls for it and you accept the upkeep.
Waterproofing: membrane systems and sloped substrates behind every tiled wet area — the part you never see, and the part that matters most.
Fixtures and ventilation: marine-grade and stainless fixtures that resist corrosion, and correctly sized exhaust ventilation to keep humidity and mold in check.
Neighborhoods and Cities We Serve
We remodel bathrooms across all three South Florida counties — including Coral Gables, Pinecrest, Coconut Grove, Miami Beach, Key Biscayne, Brickell, Aventura, Doral, Palmetto Bay, and South Miami in Miami-Dade; Fort Lauderdale, Hollywood, Weston, and Parkland in Broward; and Boca Raton, Wellington, and Palm Beach Gardens in Palm Beach.

Frequently Asked Questions
Do I need a permit to remodel a bathroom in Miami?
Yes, in almost all cases — any plumbing, electrical, or structural work requires a permit and inspections. We handle the entire permit for you.
How long does a bathroom remodel take?
Typically 4 to 8 weeks. Tile and slab lead times and inspection scheduling are the usual variables, and we plan around both.
Can you move the toilet, shower, or plumbing?
Yes. Relocating fixtures and the plumbing stack is exactly the kind of work that needs licensed sealed plans and permits — both of which we handle in-house.
Can you convert my tub into a walk-in shower?
Absolutely. Curbless walk-in showers and wet rooms are among our most-requested conversions, built with proper slope, drainage, and waterproofing.
