Option 1: Custom Tile Shower

🟣 Full Custom Tile Conversion

Premium qualityPermit always required

Remove existing tub and surround completely. Waterproof membrane applied to concrete backer board or Wedi/Schluter foam panels. Tile set on waterproof substrate. Custom linear or center drain installed. In FL: use large-format porcelain tile (24x24 or larger) — fewer grout lines means less mold and mildew growth in FL's humidity. White or light grout requires monthly sealing in FL. Dark grout is easier to maintain but can look dingy when FL hard water leaves calcium deposits. Epoxy grout is ideal for FL showers (no sealing required, resists mold). Schluter KERDI or Redgard membrane system recommended for FL where high humidity makes standard mesh mat systems vulnerable to water intrusion behind tile over time.

Cost range (FL)$4,500-$18,000
Project duration5-14 days
FL permit requiredYes — always
Lifespan (FL)20-40 years
Option 2: Prefab Shower Kit / One-Day Bath

🔵 Prefab Acrylic/Fiberglass Kit

Faster installPermit may apply

Prefab acrylic or fiberglass shower surround panels fit over existing tub area framing (typically 60x30 or 60x32 inch tub-size opening). One-day bath conversion systems (Bath Fitter, Re-Bath, and similar) install an acrylic liner directly over existing tub or new shower base. In FL: prefab kits are highly moisture-resistant but can yellow in FL UV if exterior light sources. Acrylic is easier to clean in FL hard water — calcium deposits wipe off without damaging surface. Fiberglass (lower cost) is more prone to crazing (micro-cracks) over time in FL humidity and heat cycling. One-day systems are ideal for rental properties, vacation homes, or snowbird FL properties where speed and cost matter more than premium appearance.

Cost range (FL)$1,800-$8,000
Project duration1-3 days
FL permit requiredUsually yes — check county
Lifespan (FL)10-25 years
Option 3: Walk-In / Barrier-Free (Aging-in-Place)

🟢 Barrier-Free Walk-In Shower

ADA compliantPermit required

Remove tub and lower the shower floor to grade level — no step-over threshold. Requires subfloor modification and linear drain installation to achieve zero-threshold entry. FL is one of the fastest-aging states by population share — barrier-free shower installations have increased 40%+ since 2020. Required for ADA compliance if adapting for wheelchair user. FL-specific: in slab-on-grade homes (majority of FL construction), achieving barrier-free entry requires cutting the concrete slab to lower the drain — a significant structural work item. In FL homes with crawl spaces (older FL stock, some panhandle homes), barrier-free is easier to achieve without slab cutting. Roll-in shower variant (for wheelchair users) requires 36x36 inch minimum with 60-inch turning radius space outside shower.

Cost range (FL, slab home)$6,000-$22,000
Project duration7-18 days
FL permit requiredYes — structural work
Lifespan (FL)30-50 years
Drain Reconfiguration: Tub to Shower

Converting from tub to shower requires drain location change. Tub drain is typically at the foot of the tub (near wall). Shower drain is typically centered or uses a linear drain along one wall. In FL slab homes this requires cutting the concrete slab to relocate the drain — a $400-$1,200 add-on. Options:

Center drain (standard)Lowest cost — slab cut may be minor
Linear drain (against wall)Requires slab cut + longer drain body
Use existing tub drain locationPossible with sloped tile to corner
FL slab cut add-on cost$400-$1,200
FL ADA + Aging-in-Place Shower Specifications
Minimum Shower Dimensions (ADA)

Transfer shower (for person with disability who can transfer from wheelchair): 36 x 36 inches minimum. Roll-in shower (wheelchair enters): 36 x 60 inches minimum, with 60 x 60 inches preferred for independent use. FL Fair Housing Act applies to multi-family buildings (4+ units) built after 1991 — requires accessible design. Single-family FL homes have no mandatory ADA requirement but many FL homeowners are proactively converting for aging-in-place.

Grab Bar Requirements (FL Aging-in-Place)

ADA-compliant grab bar installation requires blocking in walls during conversion — cannot be added effectively post-construction without wall access. Install 2x10 blocking between studs at 33-36 inches from floor on all three walls during tile phase. Grab bar locations: horizontal bar at 33-36 inches on sidewalls; vertical bar at 18 inches from threshold on entry wall; diagonal bar in corner if transfer seat installed. FL Building Code does not mandate grab bars in residential single-family, but FL Medicaid Home and Community-Based Services program may fund grab bar installation for eligible FL residents.

Seat Requirements

Fold-down teak or teak-alternative shower seat: ideal for FL showers (humidity-resistant, no rust). ADA bench seat: 17-19 inches from floor, 15 inches deep, 24-48 inches long. FL-specific: teak wood requires annual oiling in FL humidity to prevent mold growth between wood slats. Solid surface (Corian) fold-down seats are lower maintenance in FL climate. For wheelchair-level transfer seat: seat must be 17-19 inches from floor, located at 90-degree angle to entry for transfer from wheelchair.

Threshold and Entry (FL Barrier-Free)

ADA standard allows maximum 1/2 inch threshold. True barrier-free (zero threshold) preferred for FL aging-in-place. FL slab homes: achieving zero threshold requires lowering shower floor below slab level — concrete cutting required. In FL homes with wood subfloor (less common, primarily panhandle and older homes), can be achieved by building up surrounding floor height instead of lowering shower. Linear drain is the most elegant solution for zero threshold in FL tile showers — allows completely flat shower entry floor.

FL Handheld Showerhead (Required for ADA)

ADA requires adjustable handheld showerhead on slide bar, minimum 59-inch hose. In FL: install dual-function showerhead allowing switch between fixed and handheld without tools. FL water pressure: FL municipal pressure typically 60-80 PSI — verify PRV setting before installing high-demand showerhead (multiple function heads can reduce pressure). Thermostatic shower valve (set-it-and-forget-it temperature) strongly recommended for FL aging-in-place — prevents scalding for cognitively impaired users and elderly with reduced heat sensitivity.
