Tub-to-Shower Conversion in Miami: Scope, Timeline, and What You’ll Pay
A tub-to-shower conversion removes your existing bathtub and replaces it with a dedicated shower enclosure, typically finishing in 5 to 10 working days depending on material lead times and whether plumbing stays in place. In Miami, this job runs $3,500 to $10,000 for most homes we work on. Call (844) 665-0162 and we’ll walk through your exact layout and give you a written estimate at no charge.
How We Handle Tub-to-Shower Conversion from Demo to Final Inspection
We’ve done enough of these in Miami’s older neighborhoods to know where the surprises hide. Here’s how the work actually breaks down, and what you’ll need to decide at each point.
Stage 1: Site measure and plumbing assessment - 1 day
We show up, photograph everything, and determine whether your existing drain location works for a shower pan or needs relocation. In Coral Gables and Coconut Grove homes from the 1960s, we often find galvanized supply lines that are past their service life. You’ll decide here whether to replace just the visible valves or open the wall and update the whole stack. That choice alone can swing your budget $800 to $2,500.
Stage 2: Demolition and substrate inspection - 1 to 2 days
The tub comes out, the surround gets stripped to studs, and we check what we’re working with. Miami’s CBS construction from the 1940s through 1970s means concrete block walls with furring strips - not the open stud bays you’d find up north. We need to verify those strips are solid enough to accept new backer board and tile weight. If the rebar behind the block is corroding from decades of salt-air intrusion, we flag it before closing anything up.
Stage 3: Rough plumbing and pan installation - 1 to 2 days
If we’re keeping the drain where it is, this moves fast. If we’re moving it for a larger footprint or curbless entry, we cut into the slab, which triggers a different inspection path with Miami-Dade. The shower pan goes in - either a prefabricated acrylic base or a traditional hot-mop / membrane system - and you’ll decide here based on your tile selection and whether you want a curbed or curbless entry.
Stage 4: Wall finish and fixture set - 2 to 4 days
Backer board, waterproofing membrane, tile or solid-surface panels, then grout and seal. This is where material choice matters most. Large-format porcelain takes longer to set and level but gives a cleaner look. Acrylic wall systems go up in hours but limit your design options. You’ll have already picked your tile and fixtures during stage 1 so we’re not waiting on deliveries.
Stage 5: Trim, glass, and final inspection - 1 to 2 days
Valves, showerhead, door or enclosure, and cleanup. If your project required a permit - most do if plumbing moved - we coordinate the Miami-Dade inspector’s final sign-off. We don’t consider the job done until that sticker is on the permit card.
The Material and Configuration Choices That Define Your Shower
Every tub-to-shower conversion forces a handful of real decisions. These aren’t upsells - they’re the variables that determine how the space works and holds up.
- Shower pan: prefab acrylic vs. tiled with membrane. Acrylic bases run $400 to $900 installed and carry manufacturer warranties against leaks. Tiled pans with a traditional hot-mop or Schluter-Kerdi membrane cost more upfront but let you match floor tile exactly and avoid the “insert” look. For Miami’s humidity, either works if the weep holes and slope are right.
- Wall surround: acrylic panels, solid surface, or tile. Acrylic systems like those from Kohler or Delta go up in a day and resist mold in our climate. Solid surface - think Swanstone or Corian - gives seamless corners and mid-range pricing. Full tile offers the most design flexibility but demands proper waterproofing; we’ve seen too many Allapattah bathrooms with failed grout from the wrong membrane behind it.
- Glass enclosure: framed, semi-frameless, or frameless. Framed is economical and tolerates out-of-plumb walls common in older Miami homes. Frameless needs precise alignment and heavier hardware but opens the visual space. For a 60-inch opening, you’re looking at roughly $800 framed to $2,200 frameless.
- Plumbing fixtures: builder grade through designer. Moen, Delta, and Kohler cover most of our jobs. Pressure-balancing valves are code in Miami-Dade; thermostatic valves add $300 to $600 but hold temperature when someone flushes elsewhere in the house. Worth it in multi-generational homes we see in Brownsville and Flagami.
- Curb vs. curbless entry. Curbless needs the floor recessed or the pan built up to meet drainage slope, which can add $1,200 to $2,500 depending on slab work. It’s the right call for aging-in-place plans, but not every existing bathroom layout accommodates it without structural changes.
What Tub-to-Shower Conversion Costs in Miami, FL
Most tub-to-shower conversions we quote in Miami fall between $3,500 and $10,000. Here’s what pushes a job toward the low or high end of that range:
| Cost Driver | Low-End Scenario | High-End Scenario |
|---|---|---|
| Existing layout | Drain and valve stay put; no plumbing moves | Drain relocated, wall opened, supply lines replaced |
| Shower size | Standard 60″ x 30″ alcove | Expanded to 60″ x 36″ or larger with bench |
| Wall finish | Acrylic surround system | Floor-to-ceiling porcelain or natural stone tile |
| Glass and hardware | Framed sliding door | Frameless enclosure with heavy-glass and custom hardware |
| Structural surprises | Clean demo, solid substrate | Corroded furring, rebar repair, or slab cutting |
Our written estimates include demolition, disposal, pan and waterproofing, wall finish to 8 feet, basic plumbing trim, and a standard framed glass door. What’s typically separate: permit fees (Miami-Dade charges vary by municipality), any electrical work for lighting or fan upgrades, and premium fixtures you source yourself. We line-item everything so you’re not guessing.

What Miami’s Housing Stock and Rules Mean for This Job
Miami-Dade County runs its own Notice of Acceptance (NOA) product approval system, completely independent of Florida’s statewide building code. Every window, door, roofing assembly, and structural fastener has to pass the county’s hurricane-simulation testing before it can legally be installed here. A product approved in Broward County one mile north may be code-illegal in Miami, which means we source and document everything to Miami-Dade standards before we pull a permit. Contractors from outside the county routinely fail inspection on this - we’ve been called in to fix their paperwork.
The central Miami ZIPs we work most - 33155, 33156, and the surrounding areas - are dominated by CBS homes built between the 1940s and 1970s. In Little Havana, Flagami, and Overtown, that means concrete block walls with furring strips, original single-pane aluminum windows, and rebar that’s been breathing salt air for sixty-plus years. When we demo a bathroom in these houses, we’re checking for moisture intrusion behind the block and corroded steel that could compromise new tile backing. It’s not rare to find a tub surround that looked fine from the outside hiding crumbling plaster and rusted lath.
Water pressure and drainage also behave differently here. Miami sits on porous limestone with a shallow water table, and during king tides water rises through the substrate itself. That hydrostatic pressure affects how we detail shower pans and slab penetrations - conventional below-grade waterproofing from other markets doesn’t account for water pushing upward. We spec accordingly.
Many of the homes we work on in Coral Gables and Coconut Grove sit within HOA jurisdictions with design review boards. If your property requires architectural committee approval for exterior window changes or visible plumbing vent modifications, we build that timeline into our schedule so you’re not waiting on a meeting while your bathroom sits torn apart.

Frequently Asked - Tub-to-Shower Conversion in Miami
Most conversions finish in 5 to 10 working days, with material lead times adding possible delay. Acrylic wall systems and standard pans keep us on the shorter end; custom tile and frameless glass push toward two weeks. We schedule only after all materials are confirmed in hand, so we’re not waiting on a backordered valve while your bathroom is unusable. Call (844) 665-0162 to check current lead times.
Yes, if plumbing lines move or the drain gets relocated - which describes most conversions that change the footprint. Miami-Dade requires permits for any plumbing modification, and the inspector will verify NOA-compliant materials and proper venting. We pull permits as part of our standard process and coordinate all inspections. Jobs where the tub and shower share identical dimensions and plumbing locations sometimes qualify as repair, but we verify that with the building department before starting.
Often yes, if you’re keeping the same 60-inch by 30-inch alcove and the drain location works for a shower pan slope. This is your most economical path and typically lands near the $3,500 to $5,500 range. The limitation is design: you’re locked into that footprint, and a standard tub drain at the far end may not align optimally with a center-drain shower pan. We assess this on site and show you both options.
Surface refinishing a tub runs $400 to $700 but leaves you with a tub you don’t want. A tub-to-shower conversion starts at $3,500 and gives you a purpose-built shower with modern waterproofing, accessibility, and resale value. For Miami homes from the 1960s and 1970s, we rarely recommend refinishing - the underlying plumbing and surround are usually at end of life anyway. Call (844) 665-0162 and we’ll look at what you’re working with.
We warranty our workmanship for one year on all bathroom remodeling projects, and the materials carry their own manufacturer warranties - typically lifetime on acrylic pans, 10 to 15 years on shower valves, and varied coverage on glass enclosures. Our Bathroom Remodeling crew documents every warranty card and registers products in your name where the manufacturer allows it. If something fails, you call us, not a 1-800 number.
