Do I need a permit to install a walk-in tub in Florida?

In most Florida jurisdictions, yes. The installation replaces plumbing fixtures and connections and often adds a dedicated electrical circuit — both permitted work under the Florida Building Code. Narrow like-for-like exemptions exist in some counties, but confirm with the building department, never with the salesperson.

How much does a walk-in tub permit cost?

Typically $100–$500 in Florida depending on county and the trades involved, plus included inspections. It is a minor line in a $5,000–$15,000 project and the contractor should both pull it and price it in the itemized quote.

Who pulls the permit — me or the contractor?

The contractor. In Florida the permit-puller takes responsibility for code compliance, so a contractor pushing you toward an owner-builder permit for their own installation is transferring liability to you. Refuse, and reconsider the contractor.

What happens if I install a walk-in tub without a permit?

Nothing — until something happens. Unpermitted bathroom work surfaces at resale (disclosure, inspection flags, retroactive permits), at insurance claim time after leaks, and in warranty disputes. Retroactive permitting can require opening finished walls. The $300 you saved is the cheapest part of the story.

Do tub-to-shower conversions need permits too?

Yes, the same logic applies — drain and valve work is plumbing scope. Zero-entry builds that recess the pan into the slab involve even more inspection interest. Any reputable Florida conversion company pulls permits routinely.

Do You Need a Permit to Install a Walk-In Tub in Florida?

In most of Florida, yes — replacing a bathtub with a walk-in tub requires a permit, because the job involves replacing plumbing fixtures and connections, and often adds electrical work for pumps and heaters. The permit is cheap, the contractor handles it, and the homeowner barely notices. Skipping it is where the stories get expensive.

Why this job is permit territory

Plumbing replacement. Florida Building Code treats swapping a tub — new drain connection, new supply lines, new valve — as permitted plumbing work in most jurisdictions. This covers walk-in tubs and tub-to-shower conversions alike.
Electrical additions. Jetted and heated tubs need a dedicated GFCI-protected circuit. That is permitted electrical work everywhere.
The drain upgrade. The 2-inch fast drain worth ordering (here’s why) modifies the drain line — again, plumbing scope.
Exceptions exist but are narrow. Some jurisdictions exempt true like-for-like fixture swaps with zero line changes. A walk-in tub install almost never stays that clean — and “no permit needed” should come from the building department, not the salesperson.

What it costs and who handles it

Permits for this scope typically run $100–$500 depending on the county and the trades involved, plus the inspection visits — usually a rough-in check and a final. The contractor pulls the permit. That sentence matters: in Florida, the party who pulls the permit owns responsibility for the work meeting code. A contractor who asks the homeowner to pull an owner-builder permit for their installation is shifting liability onto you — a known move worth refusing. The installer-vetting checklist covers this and the license check that goes with it.

How unpermitted work comes back

1At resale. Florida sellers disclose known unpermitted work, buyers’ inspectors flag bathroom remodels routinely, and deals renegotiate or die over it. Retroactive permits cost multiples of the original fee and can mean opening finished walls for inspection.
2At claim time. A water leak from an unpermitted, uninspected install gives your insurer an argument precisely when you need them cooperative. Florida homeowners’ insurance is hard enough already.
3At warranty time. Manufacturers can lean on “improper installation” to deny claims; a passed inspection is your evidence the install met code.
4With the county. Code enforcement can require permits after the fact, with penalties — typically triggered by a neighbor complaint, a sale, or another permit application on the same house.

The smooth version: what should happen

On a well-run job the permit is invisible to you: the contractor files it before work starts (many Florida counties take same-week online filings for fixture replacement), schedules the inspections around the install, and the one-to-two-day timeline absorbs them. Your only two jobs: confirm “you pull the permit, yes?” before signing, and hold final payment until the final inspection passes. Put both in the contract.

Condo note for South Florida: in buildings from Miami-Dade to Broward, association approval is a second, separate gate — wet-wall rules, insurance certificates, work-hour windows. The county permit does not waive the condo board, or vice versa. Installers experienced with condo work handle both; ask directly how many condo installs they have done.
