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 landing around $7,500 for a standard 5-foot alcove conversion. The spread comes down to materials, plumbing scope, and whether you’re dealing with a second-story bathroom in an older home or a ground-floor slab in a newer build. Homeowners who get a written quote before demo day starts avoid the worst of the price surprises.
Key Takeaways
- Typical range: $4,130 – $11,800 for a complete tub-to-shower conversion in Miami.
- Most common job: $6,500 – $8,500 for a standard alcove conversion with mid-range tile and a glass door.
- Biggest cost drivers: plumbing relocations, waterproofing method, tile selection, and glass enclosure choices.
- Timeline: 3 – 7 days for most conversions; 2 – 3 weeks if structural work or full plumbing rough-in changes are required.
- Written pricing matters: Penhallow Remodeling Miami gives you the number in writing before any work begins, and backs it with a 365-Day Done Right Promise.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s where the money goes on a typical Miami tub-to-shower conversion. These are real ranges for the local market, not national averages pulled from a database. We see these numbers every week across neighborhoods from Kendall to Coral Gables to Little Havana.
| Line Item | Low End | High End | Notes |
|---|---|---|---|
| Demolition & disposal of existing tub | $450 | $1,100 | Cast iron tubs cost more to remove than acrylic; second-floor jobs may require cut-in-place removal |
| Plumbing rough-in adjustments | $350 | $2,400 | Moving the drain from tub position to shower center is the most common added scope; older Miami homes with cast iron drain lines push this higher |
| Shower pan / base | $300 | $1,300 | Acrylic or fiberglass pan on the low end; custom tile pan with hot mop or Schluter waterproofing on the high end |
| Wall waterproofing & substrate | $500 | $1,800 | Backer board with surface membrane vs. full foam board system; this is the layer most likely to fail if done by a low-bid contractor |
| Tile & installation | $900 | $3,500 | Basic 4×4 ceramic at the low end; large-format porcelain or natural stone at the top |
| Shower valve, trim, and showerhead | $350 | $1,200 | Kohler and Moen mid-range trim kits are the sweet spot; thermostatic valves cost more than pressure-balance |
| Glass enclosure | $600 | $2,200 | Framed sliding door vs. frameless semi-custom glass with a pivot hinge; frameless is the biggest visual upgrade |
| Grab bars, shelving, seating | $100 | $900 | Built-in corner seat or niche shelving adds real value for aging-in-place plans |
| Permits & inspection | $250 | $700 | Miami-Dade requires permits for plumbing changes; licensed contractors pull these as standard |
The single biggest swing in Miami is plumbing. If your existing tub drain and supply lines line up with the new shower configuration, you save hundreds. If the plan calls for moving a drain across a concrete slab on grade, that’s a different job entirely. Slab cutting, re-routing drain lines, and re-pouring concrete can add $1,500 to $3,000 to the bottom line before a single tile goes up.
What Affects Tub-to-Shower Conversion Pricing in Miami
- Foundation and floor level. Miami homes are almost entirely slab-on-grade or elevated. Slab work means concrete cutting for drain relocation, which costs more than working through wood-framed floors in elevated homes. A second-story bathroom conversion in a Coral Gables or Coconut Grove home with wood subfloor usually costs less on the drain side than the same job on a ground-floor slab in Kendall or Homestead.
- Waterproofing method. A fiberglass surround kit with a pre-molded pan runs the cheapest. A full mortar-bed tile pan with sheet membrane waterproofing is the Miami standard for longevity given the humidity, and it costs $1,200 – $2,500 more than a basic insert system. This is the one line item we recommend never cutting.
- Tile size and material. Large-format porcelain panels (24×48 and up) look sharp but require more labor for layout and cutting, and Miami’s soft limestone bedrock doesn’t make any difference here: it’s purely a labor equation. Simple 12×24 porcelain keeps the budget predictable. Natural stone like travertine or marble looks beautiful but demands sealing and ongoing maintenance in South Florida’s mineral-heavy water.
- Glass enclosure style. A framed sliding door starts around $600 installed. A true frameless 3/8-inch tempered glass panel with custom hinges and a transom for airflow runs $1,800 – $2,200 in Miami. The frameless look is worth it if the surrounding tile work is the star of the room.
- Age of the home and existing plumbing. Homes built before the late 1970s in Miami often have cast iron drain lines that have corroded from decades of shifting soil and a high water table. We sometimes open a wall and find the drain flange is rusted beyond reuse. That’s a few hundred dollars in repair before the new work starts, and it’s not line-itemed on a lowball quote.
- Permit requirements. Miami-Dade County requires plumbing permits for tub-to-shower conversions when the drain is relocated or modified. A licensed contractor handles this as part of the job. If a quote does not include permit fees, ask whether they’re being pulled at all. Unpermitted plumbing work becomes a problem at resale, and Miami home inspectors flag it every time.
How to Save on Tub-to-Shower Conversion
Saving money on a tub-to-shower conversion is less about finding a cheaper contractor and more about making cheaper choices without cutting the things that keep the shower from leaking into the floor. Here’s what we tell Miami homeowners who want to keep the number reasonable.
- Keep the drain where it is. This is the single biggest cost variable. If you can design the shower around the existing drain location, you skip the slab work or floor framing work entirely. A shower that spans the old tub footprint saves $800 – $2,500 compared to moving the drain to a new center point.
- Choose standard tile sizes. 12×24 porcelain is common enough that installers are efficient with it, which keeps labor down. Mosaic sheets on the shower floor are fine, but a full mosaic wall costs more per square foot in labor than the material itself.
- Skip the bench, keep the niche. A built-in corner bench adds $300 – $700 in materials and waterproofing labor. A single recessed niche shelf costs less and adds real daily utility for shampoo and soap.
- Use a mid-range valve with a quality brand name. Kohler and Moen both sell pressure-balance valve kits in the $250 – $450 range that hold up fine in Miami’s water. You don’t need a thermostatic valve with three diverter ports unless you’re building a multi-head spa shower.
- Ask about the 365-Day Done Right Promise before you sign. The most expensive shower is the one that has to be torn out and rebuilt because the waterproofing failed. Penhallow Remodeling Miami puts its guarantee in writing on every job: if something isn’t right within the first year, we return and fix it at no charge. That costs you nothing up front and can save you thousands if a builder-grade install fails.
One more note: we offer free estimates with no obligation. Call (850) 988-7559 and we’ll walk through your bathroom, your budget, and the exact written price for the work. The number we give you on day one is the number on the invoice. That’s the standard Trevor Nash and the team work under, and it’s been that way since the Kingswell standard was established in 2004.
Is Tub-to-Shower Conversion Worth It in Miami?
Short answer: yes, for most homeowners. A well-executed conversion removes the tub you haven’t used in years and replaces it with a walk-in shower that’s safer, more accessible, and more in line with what Miami buyers look for in 2026. The return is real, but the motivation should be practical first: many of our customers in neighborhoods like Shenandoah, Allapattah, and North Miami tell us the tub was a trip hazard and a cleaning burden. The shower solves both.
For resale, the picture is nuanced. Homes with at least one bathtub still appeal to buyers with young children, so if this is the only full bathroom in the house, think carefully before removing the tub entirely. In a 2-bath or 3-bath home, converting one tub to a walk-in shower is almost always a net positive. The curb appeal of a frameless glass shower with good tile beats a chipped fiberglass tub every time.
Common Tub-to-Shower Conversion Scenarios and What They Cost
Standard Alcove Conversion (5-foot tub to shower)
This is the most common tub-to-shower conversion in Miami. The tub comes out, the drain stays roughly in place, the standard 60-inch alcove gets waterproofed, tiled, and fitted with a glass door. Budget: $4,500 – $7,800 for mid-range materials.
Full Bathroom Reconfiguration with Drain Relocation
When the shower moves to a different wall, or the plan calls for a curbless entry with the drain moved to the center of the new space, slab work enters the picture. That pushes the job into the $8,000 – $11,800 range depending on tile and glass. Curbless showers in Miami require careful planning to keep water where it belongs, and this is not the job to hand to the lowest bid.
Accessible or Aging-in-Place Conversion
Low-threshold or zero-entry showers with built-in grab bars, a fold-down seat, and a handheld sprayer run $6,500 – $10,500 in Miami. The higher end reflects custom tile and more plumbing components. These conversions hold their value particularly well in retirement-oriented neighborhoods like Aventura and parts of Kendall.
High-End Conversion with Custom Tile and Frameless Glass
Large-format porcelain on all three walls, a custom tile pan, a built-in niche with accent tile, and a 3/8-inch frameless glass enclosure with transom: this is the $9,500 – $11,800 end of the range. It’s what we see homeowners choosing in Coconut Grove and Pinecrest when they plan to stay in the home long-term.
FAQs – Tub-to-Shower Conversion Cost
How much does a tub-to-shower conversion cost in Miami in 2026?
A tub-to-shower conversion in Miami costs $4,130 – $11,800 in 2026. The typical project runs $6,500 – $8,500 for a standard alcove conversion with mid-range tile, a quality shower valve, and a framed glass door. Call (850) 988-7559 for a free written estimate for your specific bathroom.
Is it cheaper to convert a tub to a shower or replace the tub?
Converting a tub to a shower typically costs $4,130 – $11,800, while a straightforward tub replacement runs $1,800 – $4,500 depending on the tub and plumbing condition. The conversion costs more because it involves full waterproofing, tile work, and a new shower base. If you’re replacing a tub anyway because it’s stained or damaged, the conversion is often the better long-term play.
How long does a tub-to-shower conversion take?
Most tub-to-shower conversions in Miami take 3 – 7 working days. A standard alcove job with no drain relocation and a pre-fabricated pan can be done in three days; custom tile pans, drain relocations, and permit inspections push the timeline to one to two weeks. Penhallow Remodeling Miami gives you a defined arrival window before the project starts, and our background-checked, uniformed technicians are the ones who show up.
Do I need a permit for a tub-to-shower conversion in Miami?
Yes, in most cases. Miami-Dade County requires a plumbing permit when the drain or water supply lines are modified. If the conversion is a straight swap with no plumbing changes, some jobs may not require one, but licensed contractors pull permits as standard practice to keep the inspection record clean. Unpermitted work can complicate a home sale, and Miami inspectors are thorough about checking.
Can you convert a tub to a shower in a small bathroom?
Yes. A standard 5-foot tub alcove converts to a shower using the same footprint, so the room doesn’t get any smaller. In a small bathroom, a clear glass door instead of a curtain or frosted panel makes the space feel larger. Budget $4,800 – $8,000 for a small-bathroom conversion in Miami with standard finishes. Call (850) 988-7559 and we’ll give you a written price for your exact layout.
What’s the most expensive part of a tub-to-shower conversion?
Plumbing relocation and waterproofing are the two most expensive components. Moving a drain across a concrete slab in Miami can add $1,500 – $3,000 to the job. Proper waterproofing with a quality membrane and tile-ready substrate runs $500 – $1,800 on its own. These are the two places where cutting costs creates the highest risk of a failed shower, so we recommend protecting the investment rather than trimming it.
Why Penhallow Remodeling Miami Prices the Way We Do
Trevor Nash has a simple rule for every project that leaves the Penhallow shop: the price is written down before the work starts, the crew shows up in the window we gave you, and the guarantee is printed on the contract. It’s called the 365-Day Done Right Promise, and it states plainly that if something fails inside the first year, we come back and fix it at no charge. No service call, no re-inspection fee, no runaround.
That guarantee works because the materials behind it are from brands we trust. We install Kohler and Moen fixtures, and we build showers on waterproofing systems that carry their own manufacturer warranties alongside ours. When a Miami homeowner calls about a shower pan that’s holding water or a valve that’s leaking, we answer. A live person picks up the phone 24 hours a day, seven days a week. That’s not a claim; it’s how the office runs.
The Kingswell Way has been the standard since 2004, and it applies to every Penhallow Remodeling location. Each location is independently owned and operated, and each one works under the same three commitments: say the price before the work, show up in the window we gave, and leave the place cleaner than we found it. In Miami, that’s the promise behind every tub-to-shower conversion we quote.
