AfterHow Much Does Tub-to-Shower Conversion Cost in Miami?
A tub-to-shower conversion in Miami typically costs between $4,130 and $11,800, with most homeowners in neighborhoods like Coral Gables, Kendall, and Brickell spending around $7,500 to $9,000 for a standard 60-inch alcove conversion that includes demolition, waterproofing, new shower pan, tile walls, and a glass door. The job usually takes 3 to 5 working days once materials are on site. Permits add another $250 to $600 depending on whether you’re in unincorporated Miami-Dade or within a city like Hialeah or Miami Beach that has its own building department.
That’s the honest range we quote at Sawyer Remodel Miami. No bait pricing where the “from” number assumes you’ll do your own demo and the final invoice comes in double. Our written price covers the full scope before we pick up a single tool, and the number you approve is the number you pay.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s how a typical Miami tub-to-shower conversion breaks down line by line. These are real ranges from our 2026 project data across Miami-Dade County, not national averages that ignore South Florida labor rates and building codes.
| Line Item | Typical Cost Range (Miami, FL) |
|---|---|
| Demolition & haul-away of existing tub | $400 – $850 |
| Rough plumbing adjustments (drain relocation, valve replacement) | $600 – $1,800 |
| Waterproofing system (Schluter Kerdi or equal) | $700 – $1,600 |
| Shower pan (mortar bed or prefabricated acrylic base) | $500 – $1,400 |
| Wall tile & installation (standard 12×24 porcelain) | $1,200 – $3,200 |
| Shower valve, trim, and fixtures (Kohler or Moen) | $300 – $1,200 |
| Glass shower door (semi-frameless or frameless) | $800 – $2,600 |
| Permits & inspection fees | $250 – $600 |
| Niche, bench, and other built-in upgrades | $150 – $850 each |
Three things push a Miami job toward the top of that range faster than anything else: moving the drain, choosing a frameless glass door over a curtain rod, and the age of the plumbing behind the wall. Homes in Coral Gables and Shenandoah built before 1980 often have cast-iron drain lines that have been corroding for decades. We regularly find galvanized supply lines in those older bathrooms that need replacing once the wall is open, and that’s a real cost driver no honest contractor can hide from you on the front end.
At the bottom end, if your tub alcove is already in good structural shape, the drain can stay put, and you’re okay with a prefabricated acrylic shower base, you’re looking at the $4,130 to $6,500 zone. But understand what you’re giving up: an acrylic base flexes, it can creak, and it won’t have the same feel underfoot as a properly sloped mortar bed with tile. We’ll walk you through the difference at estimate time, not after.
What Affects Tub-to-Shower Conversion Pricing in Miami
- Drain relocation. If the new shower footprint moves the drain location, the slab or subfloor has to be opened up. In many Miami homes built on concrete slabs (which is most of them south of I-4), that’s a jackhammer job, not a saw cut. Adds $500 to $1,500 depending on distance.
- Age of the plumbing wall. Pre-1980 Miami homes, especially in neighborhoods like Little Havana, Allapattah, and parts of North Miami, live with galvanized supply lines and cast-iron drains. Code requires replacement when exposed during a remodel. That’s $300 to $900 in materials alone before labor.
- Waterproofing system choice. Schluter Kerdi membrane (the orange sheet system you see in every pro shower) runs higher on materials than a roll-on liquid membrane. But it’s what we install on almost every job because the failure mode on liquid membranes in Miami’s humidity and a settling slab is exactly what you’re trying to avoid by hiring a licensed pro in the first place.
- Glass door style. A curtain rod costs $80. A semi-frameless sliding door runs $800 to $1,400. A frameless hinged door with heavy 3/8-inch glass runs $1,800 to $2,600 installed. The frameless look is what most Miami homeowners actually want, so budget for it if you can.
- Tile selection and layout. Standard 12×24 porcelain from a local supplier like D&B Tile or TileBar in the Design District runs $4 to $9 per square foot. Large-format 24×48 slabs, handmade zellige, or marble will multiply that three or four times. Herringbone or vertical stack patterns add 20-30% to tile labor because the cuts don’t fall on grid lines.
- Permit jurisdiction. Unincorporated Miami-Dade permit fees run differently than Coral Gables, which operates its own building department with its own fee schedule and inspection timelines. We pull permits on every job where they’re required, and the fee range above reflects what we actually see across the metro.
Is Tub-to-Shower Conversion Worth It in Miami?
Here’s the practical answer: if you have a second bathtub somewhere in the house, converting the hall bath or primary bath to a walk-in shower almost always makes sense for resale. Appraisers in South Florida have shifted over the last decade. The “must have one tub” rule has softened for most buyers in the 28-to-45 bracket, especially in condos and townhomes across Brickell, Edgewater, and Wynwood where floor plans reward low-curb accessibility and a shower you can actually stand in comfortably.
If your home has exactly one bathroom and it’s the only tub, think harder. Families with young kids still want a tub somewhere. But a curbless or low-curb shower converts well for aging-in-place buyers too, and Miami’s condo-heavy market means plenty of buyers are downsizing from houses where they’ve already made this switch.
The return on investment isn’t just resale dollars. It’s the daily use. Most Miami homeowners with a 1980s or 1990s fiberglass tub-and-surround get more out of a shower they use twice a day than a tub they fill twice a year.

Walk-In Shower vs. Curbless: Cost Difference in Miami
A standard walk-in shower with a 4 to 6 inch curb adds $300 to $600 less than a true curbless entry, which requires dropping the shower pan into the floor or building up the surrounding bathroom floor to create slope. In Miami slab homes, a curbless conversion usually means the concrete subfloor gets chipped down or a raised platform gets built, and that’s $1,200 to $3,000 in extra labor depending on the slab thickness and where the drain sits.
Wheelchair-access standards (ADA-compliant 36-inch clear opening, zero threshold) run at the top of that range. If you’re converting for mobility and planning to stay in the home for years, the curbless option is worth the money. If you’re converting for resale or personal preference and a step-over is fine, save the money and put it into tile or glass.
How to Save on Tub-to-Shower Conversion
- Keep the drain where it is. The single biggest savings lever. If you can accept the shower footprint staying within the existing tub alcove, you skip slab demo and drain relocation entirely.
- Buy materials during supplier sales. Miami’s tile and bath showrooms run seasonal promotions, and we pass manufacturer rebates through at cost. We handle the ordering logistics, but timing your material selection around a sale can knock $400 to $900 off the parts line.
- Skip the built-in bench. A folding teak shower seat costs $120 and does the same job as a $700 tiled bench. We’ll never upsell you one if you don’t want it.
- Choose a prefabricated acrylic base over a tiled pan. You’ll save $600 to $1,100. You’ll also lose the custom feel, so think it through. We install both and won’t push either direction.
- Get a written, itemized estimate before you commit to anyone. Our estimates at Sawyer Remodel Miami are free, and the price goes in writing before work starts. No surprises at the invoice.
How Long Does a Tub-to-Shower Conversion Take in Miami?
Plan for 3 to 5 working days from demolition to a finished, usable shower. Here’s the honest timeline we see on the ground in Miami-Dade:
- Day 1: Demo, haul-away, and rough plumbing. Inspector visit if required by your jurisdiction.
- Day 2: Waterproofing and shower pan. The pan needs to cure overnight, and if it’s a mortar bed, the slope has to be dead-on before any tile goes down.
- Day 3: Tile walls, niche, and any trim work. This is the long day.
- Day 4: Grout, cure, and glass door measurement or installation depending on the door type.
- Day 5: Final trim, caulk, and cleanup.
Humidity extends cure times in Miami. Grout and thinset schedules have to account for our moisture levels, and we don’t cut that corner. A rush job that skips a cure is a shower that fails in 18 months. Our 365-Day Done Right Promise means if it’s not done right, we make it right, and that starts with doing the job on a schedule that holds up.
What Building Codes Apply to Tub-to-Shower Conversion in Miami?
Miami-Dade County operates under the Florida Building Code with local amendments, and the big one for showers is the waterproofing and flood-plane requirements under Chapter 27 and the high-velocity hurricane zone provisions that apply to much of the county. The practical effect: shower valves must be pressure-balanced or thermostatic (anti-scald), and waterproofing must meet the substrate standards for damp, humid climates.
We pull permits for every tub-to-shower conversion where they’re required, and we handle the inspection scheduling. If a contractor tells you a permit isn’t necessary for this work, run. A shower conversion involves plumbing modifications, and unpermitted plumbing work becomes a disclosure problem when you sell. It’s a liability you don’t want, especially in Miami where insurance and lending have tightened on unpermitted work.
How Much Does a Small Bathroom Remodel Cost Compared to a Tub-to-Shower Conversion?
A small bathroom remodel in Miami runs $5,900 to $14,160, which puts it in a similar neighborhood to a tub-to-shower conversion because the scope overlaps heavily. The difference: a small bathroom remodel might include a new vanity, flooring, paint, and lighting on top of the shower work. If you’re already down to the studs for a shower conversion, adding a vanity and floor tile is marginal extra cost, often $2,000 to $4,000 more than the shower alone.
If your goal is to fix a bad bathroom and you have the budget, doing it all at once is cheaper than sequencing it. You pay for demolition, drywall repair, and finish work once instead of twice.
FAQs – Tub-to-Shower Conversion Cost
Is it cheaper to repair or replace a bathtub?
A tub-to-shower conversion in Miami runs $4,130 to $11,800, while a full tub replacement (new tub, new surround, new plumbing) typically runs $3,500 to $8,500. If your tub has a cracked shell, a failed drain seal, or a surround that’s leaked into the wall, the repair path can approach replacement cost fast. Call (850) 801-8046 and we’ll give you a straight answer on which direction makes sense in your bathroom.
Can you convert a tub to a shower in one day?
No, not properly. A legitimate tub-to-shower conversion in Miami takes 3 to 5 working days. Anyone promising a same-day conversion is either doing a plastic insert over an unaddressed waterproofing failure or skipping cure times on the pan and grout. That’s a $1,500 problem in two years. We schedule it right the first time.
How much does a walk-in shower installation cost in Miami?
A walk-in shower installation in Miami runs $5,310 to $14,160 when built from scratch, which covers the same scope as a tub-to-shower conversion plus any slab work needed if there’s no existing alcove. If you’re converting an existing tub alcove, you fall within the lower $4,130 to $11,800 tub-to-shower range. Call (850) 801-8046 for an exact quote; estimates are free.
Does a tub-to-shower conversion increase home value in Miami?
In most Miami neighborhoods, yes, especially for condos and homes where the primary bath’s tub gets converted while a second tub remains elsewhere. Appraisers and buyers in Brickell, Coconut Grove, and Kendall increasingly favor a well-executed walk-in shower over a dated fiberglass tub-surround combo. The conversion cost of $4,130 to $11,800 typically returns 60 to 75 percent at resale, and the daily-use value is higher than a tub that rarely gets filled.
