Bathtub replacement in Florida is a like-for-like swap with one step that separates a real job from a cover-up: the open-wall inspection. When the old tub comes out, the wall behind it is exposed for the first time in years — and in a Florida bath, that wall almost always hides something, because daily splash, steam, and an aging surround feed hidden moisture and mold behind the tile where no one ever looks. A crew that slides the new tub in and re-caulks just seals that problem back inside the wall. We treat the exposed wall as the whole point of the project: we inspect it for rot and mold, remediate what we find, re-waterproof the surround with a bonded membrane, re-plumb and water-test the overflow, and only then set the new tub. We do not quote a number sight unseen; we deliver a free written line-item estimate after an in-home visit, under the FBC.

What Is Bathtub Replacement, and Why Does Florida Make It a Mold Check?
Bathtub replacement removes an old, worn, cracked, or leaking tub and sets a new one in its place — usually like-for-like, in the same footprint, with minimal layout change. The Florida difference is that the open wall behind the old tub is a one-time window into years of hidden moisture, and skipping the look is how a fresh new tub ends up sitting over old mold.
- Old tub removed to the wall — the surround comes off with the tub, exposing the framing and substrate that have been sealed up for years
- Open-wall moisture & mold inspection — the exposed cavity checked for rot, slab moisture, and mold before anything new goes back
- Fresh bonded waterproofing — a new membrane across the surround walls, replacing whatever failed and let moisture in
- Overflow re-plumbed and tested — the overflow assembly and P-trap replaced or resealed and water-tested, since a weeping overflow is a common reason the old tub leaked
- New tub set level, surround re-tiled — the new tub bedded and supported, the surround tiled over the new membrane, the deck and seam sealed
Worried What's Behind Your Old Tub?
Free in-home visit, an open-wall moisture and mold check, and a replacement plan matched to your bath — written estimate, no pressure.
What the Open Wall Reveals — and How We Fix It
An old Florida tub leaks in the same three places a new one can, except it has been leaking for years. A worn surround, a weeping overflow, and a failed deck seam all feed moisture into the framing, and the replacement is the only time you get to see and correct it. Here is what we look for and how we put it right.
- Mold and rot behind the surround — the most common find in a humid Florida bath; we remediate the mold and replace any rotted framing or substrate before resealing
- A failed or weeping overflow — frequently the quiet source of the old leak; we replace or reseal the overflow and water-test it before closing the wall
- Missing or degraded waterproofing — old tubs often had only green board and caulk; we install a new bonded membrane so the new tub is actually protected
- Slab and bottom-plate moisture — we check where the tub meets the floor and slab, correcting any moisture path that fed the damage
- Ventilation that lets steam linger — we add or upsize a humidistat exhaust fan, ducted outside, so the surround does not stay damp after the new tub is in
Why Florida Bathtub Replacements Are Different
The slab is wet, the storms come, and old surrounds hide the most. Most Florida tubs sit on or near slab-on-grade, so moisture rises from below while years of steam load from above. Add the state's flood and hurricane exposure and, on the coast, HVHZ rules, and a tub replacement here is as much a moisture-recovery job as a fixture swap.
- Open-wall inspection treated as the core of the job, because a humid Florida surround that has been sealed for years almost always hides moisture or mold
- Slab moisture-vapor emission considered where the old tub met the floor, so any ground-moisture path that fed the damage is corrected, not reburied
- Flood-resistant detailing — non-porous surround tile and a fresh membrane so the next storm or supply-line leak is a cleanup, not another teardown
- HVHZ and wind-load considerations for any bathroom window near the tub in coastal and South Florida, where product-approved glazing is required
- FBC-compliant wet-area, plumbing, and ventilation detailing on the new install

How Likely Is Hidden Damage Behind Your Old Tub?
In a humid Florida bath, hidden damage behind an old tub is the rule, not the exception — a surround that has shed water through aging grout and caulk for a decade has almost certainly fed the framing. The replacement is the moment to find it, and finding it is exactly why we open and inspect rather than reseal.
We document any moisture or mold the moment the wall opens, photograph the condition, and fold the remediation into the same crew and schedule — so a tub replacement does not stall waiting on a separate restoration contractor. Shower Remodeling Estimate →
Florida Building Code, HVHZ, and Permits for Tub Replacement
A straight like-for-like bathtub replacement with no plumbing changes may not require a permit in Florida, but any change or extension of the drain, overflow, or supply does — that work falls under the Florida Building Code. If the project includes or replaces a window near the tub in a High-Velocity Hurricane Zone (Miami-Dade, Broward, and other coastal South Florida jurisdictions), that glazing carries product-approval requirements as well.
We tell you during the estimate exactly which permits and inspections your specific replacement needs, pull them, and coordinate the inspections — so the work is built to code and documented, which protects both its performance and your home's resale.
Our 6-Step Bathtub Replacement Process
Every Pro Work bathtub replacement follows the same six-step framework — built so the open wall is inspected and corrected before the new tub goes in.
- Free in-home consultation. We assess the old tub, check the visible surround and plumbing, and flag the moisture risk a humid surround hides. You see replacement-tub options matched to your bath. No commitment.
- Written estimate. Line-item breakdown — removal, the open-wall allowance, plumbing, waterproofing, the new tub, surround tile, ventilation, and timeline — delivered after the visit.
- Tub removal & open-wall inspection. Remove the old tub and surround, then inspect the exposed cavity for rot, slab moisture, and mold. Remediation handled before anything new goes back.
- Re-plumb & re-waterproof. Replace or reseal the overflow and trap and water-test them, then install a fresh bonded membrane across the surround walls. Inspections passed before tile.
- New tub set, surround re-tiled & ventilation. Set the new tub level and supported, tile the surround over the new membrane, seal the deck and seam, and add or upsize a humidistat exhaust fan ducted to the outside.
Skip the Seal-It-Back-Up Gamble
Fast reply. Open-wall mold check. Florida-grade waterproofing. A bathtub replacement that fixes what the old one hid, the first time.
How to Identify a Qualified Florida Bathtub Replacement Crew
The new tub matters less than what happens to the wall behind the old one. A crew that reseals without inspecting buries the problem. Verify all of the following before signing anything:
- Open-wall inspection as standard
- A qualified Florida crew inspects the exposed cavity for moisture and mold the moment the old tub comes out, with photos. If the plan is to slide the new tub in and re-caulk, the old problem is being sealed back in.
- Fresh bonded waterproofing, not reused board
- The surround should get a new bonded membrane, not a re-caulk over old green board. Old waterproofing already failed once — reusing it guarantees the new tub leaks too.
- Overflow replaced or resealed and water-tested
- A weeping overflow is a common reason the old tub leaked. A reputable crew replaces or reseals and water-tests the overflow before closing the wall.
- Mold remediation handled before reseal
- If the open wall reveals mold, it must be remediated and the moisture source corrected before rebuilding. Tiling over it just relocates the problem to a fresh-looking wall.
- Written line-item estimate after a site visit
- A reputable crew assesses on-site and itemizes removal, the open-wall allowance, waterproofing, the tub, and labor. A phone quote with no inspection is a red flag.

Our Installation Standards
Every Pro Work bathtub replacement meets these installation standards:
- Florida Building Code compliance
- Plumbing, wet-area waterproofing, and ventilation built to FBC requirements, with HVHZ product-approved glazing where coastal South Florida requires it.
- Open-wall moisture & mold inspection
- The exposed cavity behind the old tub checked for moisture, rot, and mold before reseal — the step that turns a tub swap into a permanent fix instead of a cover-up.
Why Florida Homeowners Choose Pro Work for Bathtub Replacement
Most crews treat a replacement as a quick swap and reseal the wall without a look. We treat the exposed wall as the reason the job matters. The same crew that removes the old tub also inspects the cavity, remediates what it finds, re-waterproofs, and sets the new tub.
- We open and inspect, never reseal blind. The open wall is the one chance to catch hidden Florida moisture — we take it every time.
- Fresh waterproofing every job. A new bonded membrane behind the surround, not a re-caulk over the old board that already failed.
- Free in-home estimate. On-site assessment, plumbing and moisture check, line-item breakdown, no high-pressure sales tactic.
- One crew, removal to finish. Removal, remediation, re-plumb, set, and tile under one schedule — no bouncing between contractors.
