Tub-to-Shower Conversion in South Miami Heights: What It Costs and How Long It Takes
A tub-to-shower conversion in South Miami Heights typically runs $3,500-$10,000 and takes 5 to 10 working days from demo to final inspection. Most of our clients in the 33177 ZIP get their permits through Miami-Dade County and have us on-site within two weeks of signing off on the design. Call (844) 665-0162 and we’ll walk through your existing layout, give you a written estimate, and flag anything that could push your timeline or budget before we start.
How We Convert a Tub to a Walk-In Shower
We’ve done enough of these in South Miami Heights to know where the surprises hide. Here’s the actual sequence, what happens each day, and where you’ll need to make decisions.
Day 1: Demo and Discovery
We strip out the tub, surround, and any water-damaged substrate. On the older CBS homes common here, built from the 1960s through the 1980s, we often find galvanized or cast-iron drain lines that have corroded at the trap. If your home still has original plumbing, this is usually where we flag it. You’ll decide same-day: patch the existing drain or replace the run back to the stack. A drain replacement adds $400-$1,200 but eliminates callbacks.
Day 2-3: Rough Plumbing and Framing
We set the new shower pan or curbless receptor, relocate any supply lines if you’ve chosen a different valve height or layout, and frame the new surround. If you’re keeping plumbing in the same footprint, this stage moves fast. Moving the drain or switching from a tub-spout to a ceiling-mount rain head requires more pipe work and a second rough inspection. We schedule that inspection now, knowing Miami-Dade County’s queue can run 3-5 business days during peak season.
Day 4-6: Waterproofing and Tile Prep
We install cement board or foam tile backer, apply liquid or sheet membrane waterproofing, and flood-test the pan for 24 hours. You’ll have already chosen your tile and layout by this point. Large-format porcelain or natural stone requires a flatter substrate and different setting materials than ceramic subway tile, and that choice gets locked in at rough-in. We don’t source tile day-of; it delays everything.
Day 7-8: Tile, Grout, and Fixture Set
Tile goes up, grout cures, we set the valve trim, showerhead, door hardware, and any niches or bench seating. If you selected a frameless glass enclosure, we template now and order glass; lead time is typically 10-14 days, so that final install happens on a return visit. Solid-surface wall panels skip this delay entirely.
Day 9-10: Final Inspection and Punch
Miami-Dade County inspects for code compliance, water-tightness, and proper venting. We pass the permit, clean the site, and walk you through operation and care. The entire job, from our first visit to final sign-off, usually spans 3-4 weeks including permit lead time and inspection scheduling.
The Options You’ll Choose Between
Every tub-to-shower conversion in South Miami Heights involves a handful of real decisions that affect cost, maintenance, and how the space feels. Here’s where our clients typically land:
- Shower receptor: curbless vs. curbed. Curbless entry looks cleaner and ages better, but it requires lowering the subfloor or using a ramped pan, adding $800-$2,000. Curbed keeps water contained more forgivingly and costs less. In homes with the original slab-on-grade construction common in 33177, curbless often means concrete cutting, which we price separately.
- Wall surround: tile vs. solid surface. Tile gives you pattern, texture, and grout lines that need sealing every 12-18 months in South Florida’s humidity. Solid surface, like cultured marble or acrylic panels, installs faster and cleans easier but offers fewer design variations. Tile runs $8-$25 per square foot installed; solid surface lands at $12-$18 per square foot with no grout maintenance.
- Valve and fixture grade. A pressure-balanced valve from a reputable manufacturer starts around $180 and handles most residential needs. Thermostatic valves, which hold temperature within a degree, run $400-$800 and suit households with fluctuating water pressure. We spec brass-bodied valves with ceramic disc cartridges; the cheap stuff with plastic internals fails in 3-5 years here.
- Glass enclosure: framed, semi-frameless, or frameless. Framed is the most water-tight and budget-friendly at $600-$1,200. Frameless runs $1,800-$3,500 and hinges on precise tile layout and wall plumbness. On older CBS homes with settled framing, we sometimes recommend semi-frameless to accommodate slight out-of-square conditions without custom glass pricing.
- Niche, bench, or both. A tiled niche adds $300-$600. A fold-down or built-in bench adds $400-$1,000. Both eat into shower footprint, so in a standard 60-inch tub bay, we typically recommend one or the other unless you’re expanding the enclosure into adjacent space.
What Tub-to-Shower Conversion Costs in South Miami Heights, FL
In this market, expect $3,500 on the low end for a straightforward swap keeping the same footprint with an acrylic surround and standard fixtures, up to $10,000 for a curbless walk-in with tile walls, frameless glass, relocated plumbing, and upgraded valve hardware.
| Cost Driver | Low-End Impact | High-End Impact |
|---|---|---|
| Keeping existing drain/plumbing location | Baseline | Baseline |
| Relocating drain or supplies | +$400 | +$1,500 |
| Curbless entry with subfloor modification | +$800 | +$2,000 |
| Tile surround vs. acrylic | +$1,000 | +$3,500 |
| Frameless glass enclosure | +$1,200 | +$2,500 |
| Permit and inspection fees (Miami-Dade County) | $350-$600 | $350-$600 |
What moves you to the high end: moving plumbing, expanding the footprint, tile on every surface, custom glass, or discovering degraded drain lines that need replacement. What keeps you low: same layout, acrylic or solid-surface walls, framed door, and clean demo.
Our written estimates include demo, disposal, all materials we supply, labor, permit fees, and final inspection coordination. What we don’t include: your tile if you supply it (we’ll install owner-provided tile with a labor-only line item), any mold or structural remediation found behind walls, or electrical work beyond a basic exhaust fan swap. We flag these possibilities during the initial walkthrough so you’re not surprised.
What South Miami Heights Homes Specifically Do to This Job
South Miami Heights sits in unincorporated Miami-Dade, which means no city hall permit desk. Every tub-to-shower conversion pulls through the Miami-Dade County Building Department, and that county-wide queue shapes our schedules. We routinely build in an extra week for inspection availability, especially during hurricane season when permit volume spikes across the county. The inspectors here know the HVHZ code inside out; every assembly needs a Miami-Dade Notice of Acceptance, and they’ll flag unlisted products. We spec accordingly.
The housing stock tells its own story. The single-story CBS homes built from the 1960s through the 1980s that dominate 33177 often have original bathrooms with galvanized drains, cast-iron stacks, and tub surrounds installed before waterproofing membranes were standard practice. We’ve opened walls in homes near SW 112th Avenue and found concrete board with no vapor barrier, paper-faced drywall glued to block, and rusted-out tub shoes that were leaking slowly for years. The post-Andrew rebuilds, engineered to stricter standards, tend to have cleaner plumbing and better substrate but sometimes feature smaller baths designed around compact tubs that homeowners now want to open up.
Water pressure and drainage matter here more than inland Florida. The flat topography and high seasonal water table in South Miami Heights mean slab-on-grade construction with limited gravity fall. If your tub drain has always been slow, the conversion is the moment to address it, because a walk-in shower moves more water faster and will expose any restriction in the line.
Homeowners in South Miami Heights often pair interior updates with exterior work, especially after weather events. If you’re also addressing roof condition, our crew handles Metal Roofing in South Miami Heights and Tile Roofing in South Miami Heights as part of our full exterior envelope capability.

Frequently Asked - Tub-to-Shower Conversion in South Miami Heights
Active construction takes 5-10 working days, but from signed contract to final inspection, most projects run 3-4 weeks. Miami-Dade County permit review and inspection scheduling account for the difference, and we build that buffer into every timeline we quote. Call (844) 665-0162 and we’ll check current county turnaround before we start.
Yes. Because South Miami Heights is unincorporated, permits pull through Miami-Dade County, not a local city office. Any work affecting plumbing, drainage, or waterproofing requires a permit, and the county inspects rough plumbing and final completion. We handle the application, drawings, and inspection scheduling as part of our project management.
Usually, yes. If your existing drain location works with a standard shower receptor and your valve height suits a showerhead, we keep everything in place and save you $400-$1,500 in plumbing relocation. We determine this on our first site visit by measuring your tub bay and checking drain condition.
A full drain replacement from the trap to the stack typically adds $400-$1,200 to the base conversion price. We only know for certain after demo, but we can usually predict it during walkthrough by listening to drain flow, checking cleanout access, and knowing the age of your home’s plumbing. We flag the likelihood in your estimate so you’re prepared.
We warranty our workmanship for one year, and the materials we install carry their own manufacturer warranties, typically 5 years on valves and 10+ years on shower receptors from major brands. Our written estimate spells out what’s covered by us versus the manufacturer, and we register product warranties in your name where required. Call (844) 665-0162 to review coverage before you decide.
