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 somewhere around $6,500 to $8,000 when they go with a mid-range walk-in shower, standard tile work, and a quality Kohler or Moen fixture package. The range is wide because the two projects at opposite ends look almost nothing alike: a basic acrylic-surround conversion in a Doral guest bath is a very different scope than a floor-to-ceiling porcelain conversion with a linear drain and frameless glass in a Coral Gables master suite.

Tub-to-Shower Conversion Cost Breakdown (2026)
Below are the line-item ranges Rowan Construction Group uses when building a written quote for Miami homeowners. These reflect current South Florida labor rates, material costs from our vetted supplier network, and the permit fees the City of Miami and Miami-Dade County actually charge in 2026 – not national averages that undercount Florida’s humidity-driven waterproofing requirements.
| Line Item | Low End | High End | Notes |
|---|---|---|---|
| Demo and tub removal | $350 | $750 | Cast-iron tubs add cost due to weight and haul-away |
| Subfloor and substrate inspection and repair | $200 | $1,400 | Miami’s humidity means rot is found more often than not in older homes |
| Waterproof membrane (Schluter Kerdi or equivalent) | $300 | $700 | Non-negotiable in Miami’s climate; skipping it is the most expensive mistake you can make |
| Shower pan or liner | $250 | $1,200 | Custom mud-set pans cost more but allow any dimensions |
| Tile – walls (material and labor) | $900 | $3,500 | Porcelain large-format slabs push the top of this range quickly |
| Tile – floor (material and labor) | $300 | $950 | Mosaic and small-format tile costs more to set; textured tile is worth it for slip resistance |
| Drain (standard vs. linear) | $75 | $600 | Linear drains are popular in Brickell and Pinecrest remodels; they require a sloped pour |
| Plumbing rough-in adjustments | $400 | $1,800 | Moving the drain or adding a body spray outlet changes the rough-in scope significantly |
| Shower fixtures (valve, head, controls) | $300 | $1,500 | Kohler Forte and Moen Align are solid mid-range choices; Grohe and Toto push toward the top |
| Shower enclosure or door | $450 | $2,500 | Frameless glass is the most requested option in Miami; framed is less expensive and still clean |
| Permit (Miami-Dade) | $125 | $400 | Required for plumbing work; pulling permits protects you at resale |
| Niche, bench, or grab-bar blocking | $150 | $600 | Blocking must be installed before tile; adding it after is a tear-out |
Adding those ranges end-to-end produces a total of roughly $3,800 to $13,900 before any project-specific adjustments, which aligns with our published range of $4,130 to $11,800 for the vast majority of Miami conversions. Projects that push above $11,800 almost always involve custom tile work with premium large-format porcelain, frameless glass over 48 inches wide, or a full plumbing relocation. Projects that come in near $4,130 are typically straightforward acrylic-surround conversions in a secondary bathroom where the plumbing stays exactly where it is.
For context: a Tub-to-Shower Conversion in Miami sits at the lower end of the broader bathroom remodel range. A full bathroom remodel in Miami runs $10,620 to $33,040 – the conversion is a focused scope, not a whole-room overhaul, and the price reflects that.
What Affects Tub-to-Shower Conversion Pricing in Miami
- Subfloor condition discovered after demo. Miami homes built before the mid-1980s – and there are a lot of them in neighborhoods like Little Havana, Allapattah, and Coconut Grove – often have wood subfloor that has absorbed moisture for decades. We photograph every subfloor after tub removal and share that record with you before we quote any repair work. Rot repair typically adds $300 to $900 to the budget when it shows up.
- Waterproofing method and coverage. In Miami’s climate, a shower membrane is not optional – it’s the single layer standing between tile and the framing behind it. A sheet membrane like Schluter Kerdi applied to walls and floor costs more upfront than a liquid-applied membrane, but it’s the spec we recommend for any Miami bathroom that will see daily use. Skimping here is one of the most reliably expensive decisions a homeowner can make.
- Plumbing relocation and drain repositioning. If the new shower footprint stays within the tub’s original plumbing rough-in, costs stay low. Moving the drain even 12 inches – common when converting from a 30-inch tub to a 36-by-48-inch shower – requires breaking the slab (Miami homes are predominantly slab-on-grade construction) and re-routing drain lines. That alone can add $800 to $1,800 depending on depth and access.
- Tile selection and format size. The difference between a 12-by-24 ceramic wall tile and a 24-by-48 rectified porcelain slab is not just visual – it’s also labor. Large-format tile requires a flatter substrate, more precise layout, and stronger adhesive (medium-bed mortar), all of which add time. Miami homeowners in Wynwood, South Beach, and Palmetto Bay consistently lean toward the larger formats; that’s a real cost driver.
- Shower enclosure type. A curtain rod with a tension mount is the low-cost path. A semi-frameless slider runs $450 to $900 installed. A fully frameless glass enclosure with 3/8-inch tempered glass – the spec most commonly requested in Coral Gables and Pinecrest – runs $1,200 to $2,500 installed, depending on width and whether a door or a fixed panel is included.
- Permit and inspection requirements. Miami-Dade County requires a permit for any work that involves the plumbing rough-in, which includes relocating a drain or adding a new valve. Some contractors skip this step; we don’t, because an unpermitted plumbing modification shows up in a title search and can block or delay a sale. The permit fee is modest ($125 to $400) relative to what an unpermitted project costs you at closing.
BeforeAfterMiami-Specific Factors Worth Knowing Before You Decide
Miami is not a generic Florida market when it comes to bathroom remodeling, and pricing guides that treat it like one tend to undercount real costs. A few things that matter here specifically:
Slab construction is the norm. Unlike frame-construction homes up North where a plumber can often access drain lines from a crawl space or basement, nearly every Miami home sits on a concrete slab. Any drain relocation requires saw-cutting and patching the slab, which adds labor and material cost that won’t appear on a national pricing guide. We see this requirement come up in probably 40 percent of the tub-to-shower conversions we do in neighborhoods like Kendall, Hialeah, and Doral, where the homes are predominantly 1970s and 1980s slab construction.
Mold discovery after demo. Miami’s year-round humidity and the rain patterns that come through from June to October mean that older tub surrounds – especially those with grout that hasn’t been sealed in years – frequently have mold behind the wall tile. When our crew removes the tub surround and finds mold on the backer board or drywall, the right move is documented immediately in photographs and the remediation scope is written up before any new material goes in. In our experience doing bathroom work across Miami since 2007, mold discovery behind tub surrounds runs at a meaningful rate – particularly in homes in Overtown, West Miami, and other neighborhoods with housing stock from the 1950s through the 1970s.
Humidity-resistant backer board matters. Standard drywall behind tile is a known failure point in South Florida. Cement board or a glass-mat gypsum product like Dens-Shield is the correct substrate for Miami bathrooms. Our written scopes specify the backer material by name so you know what’s going into the wall before work starts.
Impact-rated glass for enclosures is worth asking about. Miami-Dade’s building code is strict on impact-resistant glazing in certain locations. Most interior shower glass doesn’t fall under the wind-load provisions that govern impact windows, but it’s worth confirming with your contractor whether your specific configuration requires tempered-and-laminated glass versus standard tempered. Rowan’s written scope names the glass spec; you’ll never be guessing.
How to Save on Tub-to-Shower Conversion in Miami
The biggest savings almost never come from cutting the spec – they come from building an accurate scope before work starts so there’s no guesswork and no change orders that inflate the final number.
- Keep the plumbing where it is. If your existing tub drain, valve, and water supply can be reused or adapted in place, you’ll avoid the single most variable cost in a Miami conversion: slab work. Ask your contractor directly whether the new shower can be designed around the existing rough-in. Often the answer is yes with a small adjustment to the shower footprint.
- Choose tile in the mid-range on the wall, splurge on the floor. Wall tile is largely visual; floor tile takes daily abuse and slip-resistance matters. A 12-by-24 ceramic on the walls at $2.50 per square foot paired with a quality textured mosaic on the floor is a smarter allocation than the reverse.
- Get the niche and blocking decisions right before tile day. A recessed shampoo niche cut into a tiled wall costs $150 to $350 when it’s built before the tile goes up. Cut it in afterward and you’re looking at a tear-out and re-tile. Same with grab-bar blocking: the wood backer costs almost nothing when it’s framed in during rough-in, and it’s a significant repair if added later.
- Use a contractor who pulls permits. This sounds counterintuitive as a savings tip, but an unpermitted bathroom conversion can require a tear-down-and-redo inspection before a home sale closes in Miami-Dade. The cost of an unpermitted job showing up at closing is substantially higher than the $125 to $400 permit fee.
- Compare written quotes, not verbal estimates. Under Clause 1 of the Haven Standard, Rowan delivers a written price before any work starts – a flat number with a defined scope, not a ballpark. Bring any written competitor quote to us and we’ll review it line by line at no charge. If another contractor’s number looks significantly lower, it’s worth understanding which line items are missing. Call (786) 321-4970 and we’ll set up a free estimate and scope review.
Tub vs. Shower: Is the Conversion Actually Worth It?
Miami buyers and appraisers in 2026 treat a tub in the secondary bathroom as a checkbox – it matters for families with young children. In the master bath, the calculus is different. Walk-in showers are consistently preferred in Miami’s luxury and mid-market segments; a well-executed conversion with frameless glass and quality tile can add real perceived value in neighborhoods like Brickell, Edgewater, and South Miami, where buyers are comparing finishes closely before making offers.
If you have only one bathroom and no tub elsewhere in the home, a real estate professional’s input is worth getting before you commit – some buyers in Miami’s family-oriented submarkets (Kendall, Cutler Bay, Palmetto Bay) still want a tub somewhere in the home. If you have two bathrooms and the tub is in the master, converting it is almost always an upgrade in the Miami market.
FAQs: Tub-to-Shower Conversion Cost in Miami
How much does a basic tub-to-shower conversion cost in Miami?
A basic tub-to-shower conversion in Miami starts at roughly $4,130 for a straightforward acrylic-surround conversion where the plumbing stays in place and no slab work is needed. This scope typically includes demo and haul-away, a new shower pan liner, an acrylic or fiberglass surround, standard fixtures, and a basic curtain or slider enclosure. It won’t include tile work or frameless glass. If you want a written number specific to your bathroom before any commitment, call (786) 321-4970 – estimates are free and delivered in writing.
How long does a tub-to-shower conversion take in Miami?
Most tub-to-shower conversions in Miami take 3 to 7 business days from the first demo day to final inspection. The range depends on tile drying and cure time (cement mortar requires 24 to 48 hours before grout, and grout requires 24 to 72 hours before the shower can be used), whether slab work is needed, and permit inspection scheduling. Miami-Dade permit inspections are typically booked within 2 to 5 business days. A project with a custom mud-set pan and full-height tile that also requires an inspection will run closer to 7 to 10 days total.
Is it cheaper to repair the existing tub or convert to a shower?
Tub refinishing in Miami costs $350 to $650 and lasts 5 to 10 years with careful use – it’s the right call if the tub is structurally sound and you want to extend its life. A tub liner overlay costs $800 to $1,400 and fits over the existing tub without demo. But if the surrounding tile is failing, the caulk is compromised, or there’s any sign of water behind the wall, a conversion is the more cost-effective long-term answer: you’re fixing the underlying problem rather than covering it. In Miami’s humidity, a partially failed tub surround that gets a cosmetic repair rather than a proper conversion tends to reappear as a water-damage problem in the wall cavity within a few years.
Do I need a permit for a tub-to-shower conversion in Miami?
Yes, in most cases. Miami-Dade County requires a permit for any project that involves modifying the plumbing rough-in, which includes changing the drain location, adding a new shower valve, or relocating supply lines. If the conversion is purely cosmetic – replacing a surround with no plumbing changes – permit requirements vary, but any work that touches the drain or valve triggers the permit requirement. Rowan pulls permits on every applicable project; the fee runs $125 to $400 and the documentation protects you at resale.
Can a tub-to-shower conversion be done without removing tile?
It’s possible in limited circumstances – specifically, some acrylic shower liner systems install directly over existing tile without full demo. The cost is lower ($2,500 to $4,500 in most Miami cases), but the result is also more limited: you can’t change the footprint, you can’t add a niche, and the liner’s lifespan is shorter than a properly waterproofed tile installation. More practically, in Miami homes where the existing tub surround has any grout deterioration or caulk failure, we consistently find moisture behind the tile when we inspect. Installing over compromised material just buries the problem. For most homeowners in Miami who want a lasting result, a full demo and new waterproof installation is the better value over a 10-year horizon.
