Tub-to-Shower Conversion in South Miami: Scope, Timeline, and What You’ll Pay
A tub-to-shower conversion removes your existing bathtub and replaces it with a dedicated shower enclosure, typically finishing in 5 to 10 working days depending on whether plumbing stays in place or gets relocated. In South Miami, most conversions we handle run between $3,500 and $10,000, with the majority of homeowners landing in the $5,500-$7,500 range for a straightforward swap using a prefabricated pan and tiled walls. Call (844) 665-0162 and we’ll walk through your specific layout - estimates are free, and we can usually schedule an on-site assessment within a few days.
How We Handle a Tub-to-Shower Conversion from Start to Finish
We’ve refined this process across dozens of bathroom projects in South Miami and the surrounding neighborhoods. Here’s what actually happens, and when you’ll need to make decisions.
Stage 1: On-site assessment and scope lock (Day 1)
We measure your existing tub footprint, check the condition of the subfloor and surrounding walls, and determine whether your drain location can stay put or needs to move. Most South Miami homes from the 1950s-1970s have cast-iron or galvanized drain lines that we need to evaluate for integrity. You’ll decide here: keep the existing plumbing layout (faster, less expensive) or relocate the drain and valve wall to reconfigure the space. This choice alone can swing your timeline by 2-3 days and your budget by $800-$2,500.
Stage 2: Demolition and rough inspection prep (Days 2-3)
We remove the tub, surrounding tile, and any water-damaged wallboard or backing. In older CBS construction, we often find previous DIY repairs or moisture intrusion behind the tub surround that needs addressing before new waterproofing goes in. If your home still has original plaster or early drywall, we may need to open more wall area than initially visible to install proper cement board or foam-core waterproofing panels. You’ll sign off on any expanded demo scope before we proceed.
Stage 3: Plumbing rough-in and drain work (Days 3-5)
Our plumber sets the new drain, pressure-tests lines, and installs blocking for grab bars or shower fixtures if you’ve specified them. South Miami’s building department requires a rough plumbing inspection before close-in, and we schedule this immediately after pressure testing passes. If you’re upgrading to a thermostatic valve or multiple showerheads, this is when we rough those in. You’ll have already chosen your valve trim finish - brushed nickel, matte black, chrome, or oil-rubbed bronze - since lead times on some designer lines run 3-4 weeks.
Stage 4: Waterproofing, wall prep, and tile or surround installation (Days 5-8)
We apply liquid membrane or sheet waterproofing to all wet-area surfaces, flood-test the pan if it’s a traditional mortar bed, then install your chosen wall finish. Tile jobs take longer than acrylic or fiberglass surround systems - typically 2-3 additional days for layout, setting, and grout curing. You’ll see the tile layout before we cut anything; we mark it out with spacers so you can visualize pattern alignment and accent placement.
Stage 5: Fixture set, glass installation, and final inspection (Days 8-10)
We install the shower door or curtain rod, set all trim, caulk perimeters, and run final water tests. South Miami requires a final plumbing inspection and certificate of completion before we formally close the permit. We handle that scheduling and walk the inspector through. You do a punch walk with our project lead, and we address any touch-ups same-day or next morning.
The Choices That Shape Your Shower
Every tub-to-shower conversion involves a handful of decisions that most homeowners don’t realize they’re making until we’re standing in the bathroom together. Here’s where your preferences actually matter:
- Shower pan type: Prefabricated acrylic or fiberglass pans ($400-$900) install fast, carry manufacturer warranties, and work well for standard 60″ x 30″ or 60″ x 32″ openings. Custom mortar-bed pans with waterproofing membrane ($1,200-$2,800) let you shape any footprint, slope precisely for large-format tile, and typically outlast prefab options by decades. The trade-off is time and cost.
- Wall surround material: Acrylic three-panel systems go up in a day, cost $800-$1,500, and resist mold but limit you to manufacturer colors and textures. Cement board with tile ($2,000-$6,000+ depending on tile selection) gives unlimited design flexibility and better resale perception, though grout requires periodic sealing in South Miami’s hard water.
- Plumbing fixture grade: Builder-basic chrome pressure-balance valves ($150-$300) work fine for simple setups. Mid-grade thermostatic valves from Moen, Delta, or Kohler ($400-$800) hold temperature steady when someone flushes a toilet elsewhere in the house. High-end architectural lines with multiple outlets and digital controls ($1,200-$3,500+) suit homeowners planning to stay long-term.
- Glass enclosure vs. curtain: Frameless glass ($1,500-$3,500) opens the room visually and contains water better, but needs squeegee maintenance to prevent spotting. A tension rod and quality curtain ($50-$150) saves money and allows easier access for cleaning or assisting children.
- Niche, bench, and accessibility features: A tiled shampoo niche adds $300-$600. A fold-down teak or phenolic bench runs $400-$900. Curbless entry with linear drain ($1,500-$3,000 additional) eliminates the threshold entirely and future-proofs the bathroom for aging-in-place.
We carry fixture lines across all these tiers - you choose the brand and grade, we handle the build. That’s how we work on every Bathroom Remodeling project, not just conversions.

What South Miami’s Homes and Rules Mean for This Job
South Miami isn’t unincorporated Kendall, and it isn’t Coral Gables. It’s a compact 2.3-square-mile municipality with its own building department, its own code amendments, and - uniquely - one of the most aggressive tree-canopy protection ordinances in Miami-Dade County. Even an interior bathroom renovation can trigger a mandatory tree survey and arborist report if your property has protected species within the construction zone’s radius. We’ve seen contractors unfamiliar with South Miami’s dual-track permitting hit delays of three to six weeks because they filed only the building application and missed the environmental review.
The housing stock we work on most here is post-WWII concrete block ranch construction from the late 1940s through early 1970s. These homes often have original flat or low-slope roofs, aging tie-beam construction, and electrical panels that won’t pass current Miami-Dade HVHZ code without upgrade. If your tub-to-shower conversion is part of a full Bathroom Remodeling in South Miami, we may need to address panel capacity before the inspector will sign off on new GFCI protection for bathroom circuits. We handle that coordination in-house rather than handing you off to an electrician.
Chronic lot-level flooding during the June-October wet season also means we inspect bathroom subfloors more carefully here than in better-drained areas. Water can wick through slab edges or find paths around aging cast-iron drains. When we find it, we fix it before closing in walls - it’s not a conversation about upselling, it’s about not rebuilding the same shower twice.
Homeowners in South Miami often pair interior work with exterior upgrades, and we’re structured for that. If you’re addressing roofing or drainage at the same time, we also handle Metal Roofing in South Miami and Tile Roofing in South Miami through the same project team.

Frequently Asked - Tub-to-Shower Conversion in South Miami
Most conversions finish in 5 to 10 working days. A straightforward swap with a prefabricated pan and no plumbing relocation can wrap in under a week; jobs with custom tile, relocated drains, or required subfloor repair extend toward two weeks. Call (844) 665-0162 and we’ll give you a firm timeline after seeing your bathroom.
Yes. South Miami’s building department requires permits for any plumbing modification, including drain replacement or relocation, and mandates both rough and final plumbing inspections. The city’s separate environmental review may also apply depending on protected trees near your property line. We pull permits and schedule inspections as part of our standard process.
Often yes, if your existing drain centerline and valve wall align with your desired shower configuration. Many standard tubs are 60″ wide with the drain at one end; a 60″ shower pan can use the same drain location. If you want a larger shower, a different door location, or to eliminate a knee wall, we’ll likely need to relocate supply lines or the drain.
The lowest-cost path is keeping your existing plumbing layout, using a prefabricated acrylic pan and three-panel surround, and selecting mid-grade chrome fixtures. In South Miami, that combination typically lands between $3,500 and $5,000. Going cheaper with unpermitted work or uncertified products risks inspection failure and water damage - we’ve been called in to redo those jobs, and they never save money.
We warranty our workmanship for one year from completion. Manufacturer warranties cover the shower pan (typically 10-30 years for acrylic, lifetime for some tile waterproofing systems), fixtures (lifetime on most mid-grade and higher lines), and glass hardware (varies by brand). We register all manufacturer warranties in your name and provide documentation at project closeout.
