What a Bathroom Remodel Costs in Florida: Real Numbers
Bathroom remodel costs in Florida range from $4,000 for a targeted refresh to $40,000+ for a full master bathroom gut-and-rebuild. The average full bathroom remodel in Florida — demo, waterproofing, new tile, vanity, plumbing, and fixtures — runs $12,000–$22,000 for a standard 5×8 bathroom.
National bathroom remodel averages ($10,000–$30,000) don't reflect Florida's specific cost structure. Florida's mandatory waterproofing inspection, slab construction, and licensed contractor requirements all push costs above what you'll find in an online cost calculator.
| Scope | Florida Range | What's Included |
|---|---|---|
| Targeted Refresh | $4,000–$9,000 | New vanity, toilet, faucets, mirror, light fixture — no tile or plumbing rerouting |
| Partial Remodel | $8,000–$15,000 | Retile floor and shower, new vanity, fixtures — existing plumbing locations stay |
| Full Remodel (5×8) | $12,000–$22,000 | Full demo, new waterproofing, tile shower, floor tile, vanity, toilet, plumbing fixtures, new light/vent |
| Master Bath Gut | $22,000–$40,000 | Full gut, custom tile shower, double vanity, soaker tub or freestanding tub, heated floor option, design coordination |
| Luxury / Custom | $40,000+ | Custom tile work, steam shower, freestanding tub, radiant heat, premium fixtures, full design-build |
Florida Building Code and the Waterproofing Requirement
Florida Building Code Section R702.4 requires waterproofing membranes in all shower and wet area tile installations. This is not optional and is enforced through a mandatory inspection before tile installation can begin. The waterproofing inspection must pass before the tile contractor can set any tile — which adds a scheduling step that doesn't exist in many other states.
Common approved waterproofing systems for Florida bathroom remodels:
- Schluter Kerdi: Sheet membrane system; widely accepted by Florida inspectors; faster install than mud bed
- Laticrete Hydro Ban: Liquid-applied membrane; very common in South Florida; requires 24-hour cure before tile
- RedGard (Custom Building Products): Liquid membrane; cost-effective; common in budget-tier remodels
- Traditional mud bed with CPE liner: Older standard; still accepted but less common due to labor cost
The waterproofing inspection typically requires 3–7 business days advance scheduling in Florida's busier construction counties (Broward, Palm Beach, Hillsborough, Orange).
Slab Construction and What It Means for Bathroom Cost
Nearly all Florida homes are built on concrete slabs. Any change to drain or supply line locations — moving a toilet, relocating a shower drain, changing a vanity to a different wall — requires cutting the concrete slab. This is a cost that is almost never included in early estimates from contractors who haven't reviewed your floor plan.
- Slab cut (single drain reroute): $800–$1,800
- Slab cut (toilet + drain relocation): $1,500–$3,500
- Slab patch after plumbing: Usually included in plumbing contractor cost but confirm in writing
A bathroom remodel that does not move any plumbing (existing plumbing locations stay) avoids slab cutting entirely and is significantly lower cost.
The most common source of hidden cost in a Florida bathroom remodel is discovering the existing shower pan was improperly installed — no waterproofing membrane, a cracked liner, or liner with improper slope to the drain. Signs include persistent grout cracking, soft spots in adjacent flooring, or musty odor. When we open a wall or floor and find this, the scope expands to a full waterproofing installation. In Florida's humidity, a compromised shower liner will cause subfloor rot and mold within 18–36 months. The right move is to fix it — but it should be disclosed upfront in the estimate, not discovered mid-demo.
Permit Requirements for Florida Bathroom Remodels
Bathroom remodels in Florida require permits when the project involves:
- Any plumbing change (drain reroute, supply line relocation, new fixtures on modified plumbing)
- Electrical work (new circuits, GFCI outlet addition, exhaust fan installation on new circuit)
- Structural changes (removing or modifying walls)
A like-for-like replacement — same tile location, same vanity location, same plumbing position — can often be done without a permit. However, the waterproofing requirement still applies and is verified through a licensed contractor's documentation in unpermitted projects.
Permit fees for bathroom remodels in Florida range from $200–$700 for a standard single bathroom, with Broward and Palm Beach counties on the higher end.
How to Get an Accurate Bathroom Remodel Quote in Florida
An accurate quote requires knowing: your current plumbing layout, whether the shower has a proper waterproofing membrane, your slab condition, and the floor plan constraints of the bathroom. A contractor who quotes a bathroom remodel without visiting the space is leaving major cost variables off the paper.
D&Co provides written, line-item estimates within 48 hours of a site visit — including whether your current shower waterproofing passes inspection, whether any slab cutting is required, and exactly what the permit process will look like for your county.
