Tub-to-Shower Conversion in Palmetto Bay: Timeline, Cost, and What to Expect
A tub-to-shower conversion in Palmetto Bay typically runs $3,500-$10,000, takes 5 to 10 working days, and almost always requires a Miami-Dade building permit because of the village’s High Velocity Hurricane Zone status. Most homeowners call us at (844) 665-0162 after the existing tub starts leaking through the wall, the surround shows mold behind the panels, or they’re simply done climbing over a 14-inch tub wall. We handle the full scope - demo, plumbing rough-in, waterproofing, tile or solid-surface walls, glass enclosure, and final inspection - so you’re not coordinating a plumber, a tile crew, and a glass company separately.
How We Handle a Tub-to-Shower Conversion Start to Finish
Every job follows five stages. Here’s what happens on your property, what we need from you at each point, and how long each stage takes.
Stage 1: Site Protection and Demo (Day 1)
We cover floors and doorways with masonite and plastic, then remove the tub, surround, valve trim, and any drywall or cement board behind it. If your home is one of Palmetto Bay’s 1960s-1980s CBS builds, we often find galvanized supply lines or a cast-iron tub that weighs 300+ pounds. That adds a few hours but doesn’t change the schedule. You’ll decide now whether to keep the existing drain location or move it to center the shower - moving it adds roughly $400-$1,200 but opens up layout options.
Stage 2: Plumbing Rough-In and Framing (Days 2-3)
Our plumber converts the tub drain to a 2-inch shower drain, installs a pressure-balanced or thermostatic valve (your choice), and stubs out for the showerhead and any body sprays. If you’re upgrading to a linear drain or curbless entry, we adjust the subfloor slope now. This is when we also frame the shower niche, bench, or half-wall if your design includes one. You’ll confirm fixture heights and niche placement at this stage - after tile goes up, changes are expensive.
Stage 3: Waterproofing and Pan Installation (Days 4-5)
We install a pre-sloped shower pan - either a bonded PVC or CPE membrane system for tile applications, or a solid-surface base if you’re going that route. Walls get cement board plus a liquid or sheet membrane meeting TCNA standards. In Palmetto Bay’s humid coastal climate, we don’t skip corners on drying time; the membrane must cure fully before tile or panels go on. Rushing this step is how showers fail in year three.
Stage 4: Wall Finishes and Fixture Set (Days 6-8)
Tile crews set field tile, accent strips, and grout; or we install solid-surface wall panels if you chose that path. Grout gets 24 hours minimum before we seal it. The glass enclosure gets templated now, though fabrication takes another week. You’ll do a walkthrough to confirm grout color, caulk lines, and fixture finish before we move to final cleanup.
Stage 5: Glass, Final Plumbing, and Inspection (Days 9-10)
We set the glass enclosure or curtain rod, install shower doors, connect trim and fixtures, and run pressure tests. Then we call for Miami-Dade’s final plumbing inspection. Once passed, we remove protection, detail the space, and turn it over. If your project is part of a full Bathroom Remodeling in Palmetto Bay, we sequence this room to stay functional as long as possible while other spaces progress.
The Choices You’ll Make for Your New Shower
Every tub-to-shower conversion involves real trade-offs. Here’s what Palmetto Bay homeowners typically weigh:
- Shower base type: Acrylic or fiberglass pans cost less ($300-$800) and install fast, but they feel hollow underfoot and limit tile size on the base. Custom tile pans with a bonded membrane run $1,200-$2,500 and give you any size, shape, or tile you want, but they add two days and require more maintenance.
- Wall surround material: Solid-surface panels (Corian, Swanstone, or similar) go up in a day, have no grout to clean, and cost $1,500-$3,500 installed. Ceramic or porcelain tile walls run $2,000-$5,500 depending on tile grade and pattern complexity. Natural stone is available but demands sealing every 6-12 months in South Florida’s humidity.
- Glass enclosure style: Framed sliding doors are the most economical at $600-$1,400. Semi-frameless hinged doors run $1,200-$2,800. Full frameless with 3/8-inch tempered glass starts around $2,200 and climbs with hardware finish and panel size. In HVHZ, all glass must be impact-rated or protected by impact-rated shutters - a detail out-of-state suppliers sometimes miss.
- Fixture grade and features: A basic pressure-balanced valve with a single showerhead costs $150-$400. Thermostatic valves with diverter, handheld, and rainhead run $600-$1,800. We spec brands like Moen, Delta, and Kohler that have local parts availability - no waiting two weeks for a cartridge when you’re down to one bathroom.
- Curb vs. curbless entry: A traditional 4-6 inch curb contains water reliably and costs nothing extra. Curbless entry requires floor recessing or a ramped transition, adds $800-$2,000, but it’s the right choice for aging-in-place plans or a seamless modern look.

A written estimate from Groundwork includes demo, disposal, plumbing rough and finish, pan and waterproofing, wall finishes, fixture set, glass enclosure, permit fees, and final inspection. It does not include bathroom vanity replacement, floor tile outside the wet area, or electrical work beyond a basic exhaust fan swap. If your tub shares a wall with a bedroom closet and you want that reconfigured, that’s a separate scope we can price.
Homeowners often pair a bathroom update with exterior work while we’re mobilized. If you’re also addressing roof condition, our crews handle Metal Roofing in Palmetto Bay and Tile Roofing in Palmetto Bay under the same project management - one schedule, one point of contact.
What Palmetto Bay Homes Specifically Add to This Job
Palmetto Bay’s housing stock and location create conditions you won’t find in Broward or Orlando markets. The village sits entirely within Miami-Dade’s High Velocity Hurricane Zone, so any permitted renovation triggers product approvals and structural scrutiny that don’t apply just north in Fort Lauderdale. Specifically, if your home was built before 1992 - which covers most of the neighborhoods off Old Cutler Road, around Palmetto Bay Park, and in the original Deering Bay Estates area - a bathroom permit can activate required upgrades to impact-rated windows, hurricane straps, or roof-to-wall connections if those systems are adjacent to the work area. We flag this during our initial site visit so you’re not surprised by scope expansion at inspection.
The salt-laden air off Biscayne Bay also means we spec brass, stainless, or PEX fittings rather than copper where code allows, and we use corrosion-resistant fasteners in any exposed framing. During rainy season, which compresses 40+ inches into roughly five months, we schedule waterproofing stages with weather windows and maintain temporary enclosure until the roof and walls are sealed. And because Palmetto Bay sits atop the Miami Rock Ridge’s dense oolitic limestone cap, any unexpected need to relocate drain lines through slab can require core-drilling rather than jackhammering - a reality that catches crews unfamiliar with local geology. We’ve worked Palmetto Bay long enough to carry the right equipment and price accordingly.
Many homes here were built with 32-inch wide tub alcoves that feel cramped by current standards. Where structure allows, we’ll discuss widening to 36 or 48 inches, but we never recommend removing a load-bearing partition without engineering. Our Bathroom Remodeling crew includes framers who know how to read CBS wall plans and identify which block walls are structural and which are partition.

Frequently Asked - Tub-to-Shower Conversion in Palmetto Bay
Most conversions take 5 to 10 working days, depending on whether you keep the existing plumbing layout and whether Miami-Dade inspection scheduling adds a day. Call (844) 665-0162 and we’ll confirm current lead times and inspection availability.
Yes. Because Palmetto Bay is in Miami-Dade’s High Velocity Hurricane Zone, any plumbing relocation, wall modification, or fixture change requires a building permit and final inspection. We pull permits as part of our standard process.
Often yes. If the existing drain and valve locations work for your desired shower size and layout, we can keep them in place and save $400-$1,200. During our free estimate, we’ll show you exactly what’s possible with your current rough-in.
The lowest-cost path uses an acrylic shower pan and surround, keeps existing plumbing locations, and installs a framed sliding door. That combination typically lands near $3,500-$4,500 in Palmetto Bay. Upgrading to tile walls, frameless glass, or moving plumbing pushes the number up from there.
We warranty our workmanship for one year, and the products we install carry their own manufacturer warranties - typically lifetime on acrylic pans, 10 years on tile waterproofing systems, and lifetime on valves from major brands. We register warranties in your name so you’re covered even if you sell the home.
