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 in 2026, with most homeowners spending $6,500 to $8,500 for a standard 5-foot alcove conversion using mid-range materials. That price includes demolition of the old tub, plumbing modifications, waterproofing, a new shower pan or tile base, wall surround, valve and trim, and finish work. High-end conversions with floor-to-ceiling tile, custom glass, and premium fixtures in neighborhoods like Coral Gables or Coconut Grove can reach $14,000 or more, but those are the exceptions.
We’ve been converting tubs in Miami-Dade County for over 20 years, and the single biggest pricing factor is whether you choose a prefabricated acrylic surround or a fully tiled walk-in shower. Prefab keeps you at the lower end; tile and glass push you toward the top. Either way, you should have a written price before any work starts.
Key Takeaways
- Typical cost range: $4,130 to $11,800, with $6,500 to $8,500 being the most common final bill.
- Low end (prefab surround, minimal plumbing changes): $4,130 to $5,500.
- Mid-range (tile walls, new valve, standard glass door): $6,500 to $8,500.
- High end (full tile, custom glass, bench, niche, high-end fixtures): $9,000 to $11,800+.
- Timeline: Most conversions take 3 to 5 working days; tiled jobs may run 5 to 7.
- Permit costs: $150 to $600 in Miami-Dade depending on scope.
- Return on investment: Tub-to-shower conversions typically recoup 60% to 70% of cost at resale in the Miami market, and they add significant appeal for buyers over 55.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here is what you’re actually paying for when a Miami contractor quotes a tub-to-shower conversion. These line items reflect current Miami-Dade labor rates and material costs. The pieces add up quickly, which is why written, line-item pricing matters.
| Line Item | Typical Cost Range (Miami, 2026) |
|---|---|
| Demolition & haul-away of existing tub | $300 to $700 |
| Plumbing modifications (moving drain to center, new mixing valve, riser to showerhead) | $600 to $1,800 |
| Shower pan or prefabricated base | $400 to $1,200 |
| Wall surround or tile installation (acrylic surround vs. tile with waterproof backer) | $1,200 to $4,500 |
| Waterproofing membrane (Schluter Kerdi or similar, on tiled jobs) | $400 to $1,000 |
| Shower valve and trim (Moen, Kohler, Delta) | $150 to $600 |
| Showerhead and arm | $50 to $400 |
| Glass shower door (frameless vs. framed vs. curtain rod) | $400 to $2,500 |
| Grab bars and safety accessories | $100 to $500 |
| Permits and inspection | $150 to $600 |
| Finish work (drywall repair, paint, trim, caulk, threshold) | $300 to $1,200 |
What drives cost up or down? First, tile versus prefab. A tile shower stall takes two to three extra days of labor and requires a waterproofing layer like a Schluter membrane; that single decision can swing the project by $3,000 or more. Second, plumbing location. Older Miami homes, especially in mid-century neighborhoods like Westchester or Shenandoah, often have cast-iron drain lines and tubs set against exterior walls. Rerouting a drain from the end of the tub to the center of the new shower footprint means opening the slab or drilling floor joists, and that labor adds up fast. Third, glass. A custom frameless glass panel with a header costs three to five times more than a rod and curtain.
What Affects Tub-to-Shower Conversion Pricing in Miami
- Your building’s age and drain type. Homes built before 1975 in neighborhoods like Allapattah or Little Havana frequently have cast-iron or copper DWV lines under the slab. If the existing tub drain is 1.5-inch and code requires a 2-inch line for the shower (which Miami-Dade building code does), you are looking at additional plumbing work that a newer home with PVC would never need.
- Tub size and shower footprint. Standard alcoves are 60 inches by 30 to 32 inches. If you’re converting a larger garden tub or a corner tub, like those found in many Kendall and Doral homes built in the 1990s and 2000s, the extra floor space means more tile, more waterproofing, and a more expensive custom pan.
- Tile selection and layout pattern. Large-format tiles (12×24 and bigger) are faster to install than subway or penny tile, which lowers labor. But large-format porcelain from premium lines can cost $8 to $20 per square foot before installation. Patterned mosaic floors in a shower niche or pan add a day of labor on their own.
- Glass door style. A fixed half-glass panel is the cheapest option besides a curtain. A swinging shower door with a magnetic latch runs more. A true frameless steam-shower door with custom hinges is the top of the range. In Miami, many homeowners skip the door entirely and do a walk-in design with a linear drain, which can offset glass costs with additional tile and waterproofing work.
- Accessibility upgrades. If the conversion includes a zero-threshold entry, built-in bench, hand shower on a slide bar, and reinforced blocking for grab bars, expect to add $800 to $2,500. Miami has a large population of aging homeowners in communities like Aventura and Kendall who are converting tubs specifically for aging-in-place, and this work is among the most valuable remodeling you can do.
- Permit complexity in your municipality. The City of Miami, Coral Gables, Miami Beach, Hialeah, and unincorporated Miami-Dade each have their own permitting process, review times, and inspection fees. Some require a licensed plumber to pull a separate trade permit. Your contractor should handle this for you, and the cost should be a line item, not a surprise.
One more thing worth knowing: Miami’s humidity and hurricane exposure affect material choices. We recommend a waterproofing membrane rated for high-humidity environments, and in second-floor condos, we use cementitious backer and a pan liner system that meets Miami-Dade’s high-velocity hurricane zone requirements for water intrusion. Those are not optional add-ons in this market; they are the difference between a shower that lasts 15 years and one that fails after three.
How to Save on Tub-to-Shower Conversion
Saving money on a tub-to-shower conversion in Miami does not mean cutting corners on waterproofing or hiring the cheapest bid from a Craigslist ad. It means making smart decisions about the big-ticket line items before work starts.
- Choose an acrylic or solid-surface surround instead of tile. A premium acrylic surround like a Kohler Luxstone or a Swan Veritek wall system runs $1,200 to $2,500 installed, versus $3,500 to $6,000 for a fully tiled shower. The look is clean, the maintenance is nearly zero, and you save two full days of labor.
- Keep the rough plumbing location as-is. If the tub valve and drain can stay in the same wall cavity, you avoid the most expensive plumbing variable. Moving a drain 18 inches in a concrete slab can cost $1,500 by itself.
- Skip the custom glass and use a fixed panel or rod. A simple single glass panel with no hinges and no header costs $400 to $900 installed. A custom frameless door with inline support can hit $2,500 before hardware.
- Shop fixtures from open-box or contractor lines. The same Moen or Kohler valve you see at a big-box showroom is available through a contractor’s trade account at 15% to 40% below retail. A reputable Miami remodeler passes that through instead of marking it up.
- Bundle the conversion with other bathroom work. If you’re already considering a new vanity or updating the floor tile, doing it all in one mobilization saves you a second round of permits, dust, and scheduling.

Mason Remodeling Co Miami provides a written price before any work begins, so there is no version of this conversation where a verbal estimate turns into a higher final bill. That is the rule, not a promotion.
Is a Tub-to-Shower Conversion Worth It in Miami?
For most Miami homeowners, yes. Here is the straight math. The average cost of a tub-to-shower conversion in Miami-Dade County lands around $7,000 to $8,000. When you sell, appraisers and buyer agents in this market treat a walk-in shower as a significant upgrade, especially in condos and in neighborhoods with older housing stock like North Miami or the Roads. For a $450,000 home in Miami, a remodeled bathroom with a walk-in shower typically contributes $10,000 to $18,000 in perceived value, and it is often cited as a top-two deciding factor for buyers over 55 and for families with mobility concerns.
There is also the practical side. Miami humidity is hard on bathtub caulking and grout. A properly waterproofed shower with a modern ventilation fan upgrade lasts longer and resists mold better than a 20-year-old tub surround. If you are keeping the house for five or more years, the conversion pays for itself in avoided maintenance and daily usability long before you sell.

FAQs – Tub-to-Shower Conversion Cost
How much does a tub-to-shower conversion cost in Miami?
A tub-to-shower conversion in Miami costs $4,130 to $11,800 in 2026, with most projects landing between $6,500 and $8,500. The range covers everything from a basic acrylic surround with a curtain rod to a fully tiled walk-in with custom glass. Call (850) 780-8123 for a written, line-item estimate for your specific bathroom; estimates are free.
Is it cheaper to convert a tub to a shower or replace the tub?
Converting to a shower is almost always cheaper than replacing a tub with a new one if the plumbing is in reasonable shape. A new cast-iron or acrylic tub with surround and valve typically runs $3,500 to $6,000 in Miami, which is near the low end of a shower conversion; the shower adds more functional and resale value for the money. Full walk-in shower conversions run $4,130 to $11,800, but they appeal to more buyers and solve accessibility problems a tub never will.
Can you convert a tub to a shower in one day?
With a prefabricated acrylic system, the tear-out and base install can be done in a single day, but a complete conversion, including plumbing, valve replacement, wall surround, finish trim, and inspection, realistically takes 3 to 5 working days. A fully tiled custom shower takes 5 to 7 working days. Anyone promising a one-day full conversion is cutting something out, and it is usually waterproofing or permit work.
Does a tub-to-shower conversion require a permit in Miami?
Yes. Any tub-to-shower conversion in Miami-Dade County that modifies the drain, water supply lines, or plumbing fixture count requires a plumbing permit, and most jobs also require a building permit for the shower pan and waterproofing inspection. Permit fees run $150 to $600 depending on scope and municipality. A licensed Miami contractor handles the permits as part of the job; be wary of any bid that excludes them.
What is the most expensive part of a tub-to-shower conversion?
Tile installation and the associated waterproofing layer is the most expensive single line item on the high end, running $2,500 to $5,500 in Miami when you count the backer board, membrane, tile, setting materials, and the three to four days of skilled labor. On lower-end jobs, the shower valve and plumbing modifications are the largest single piece, often $600 to $1,800. For an exact breakdown on your home, call (850) 780-8123 and we will give you a written price.
