Tub-to-Shower Conversion in North Miami: Scope, Timeline, and Cost
A tub-to-shower conversion in North Miami replaces your existing bathtub footprint with a dedicated shower enclosure, typically finished in 5 to 10 working days depending on whether plumbing stays put or gets relocated. Most North Miami homeowners we work with invest between $3,500 and $10,000, with the final number riding on material choices and whether the existing drain and valve locations can stay where they are. Call (844) 665-0162 and we’ll walk through your specific layout and give you a written estimate with no obligation.
How We Handle a Tub-to-Shower Conversion from Start to Finish
We break every North Miami tub-to-shower conversion into five clear stages so you know what’s happening, what decisions you need to make, and how long each phase takes.
Stage 1: On-site measure and scope lock (Day 1)
We show up, photograph the existing tub and surround, verify wall and floor framing, and test the drain line condition. You’ll decide right then whether we’re keeping the tub footprint or expanding into adjacent space, and whether you want a curbed or curbless entry. This visit takes 60 to 90 minutes. We leave with enough information to spec materials and produce your line-item estimate within 48 hours.
Stage 2: Demolition and rough inspection (Days 2-3)
We strip the tub, surround, valve, and drain down to framing. In North Miami’s 1950s-1970s CBS ranch homes, we often find galvanized drain lines, inadequate venting, or terrazzo floors that slope the wrong direction. If we’re moving plumbing, this is when we open walls and submit rough plumbing and electrical for Miami-Dade inspection. That inspection adds a day if the county’s backed up, which happens seasonally.
Stage 3: Waterproofing and substrate (Days 4-5)
We install cement backer board or a foam shower system, apply liquid or sheet membrane waterproofing, and flood-test the pan. You’ll have already chosen between a traditional mortar bed and a prefab foam pan by this point. The flood test runs 24 hours, so this stage always spans two calendar days minimum.
Stage 4: Tile, glass, and fixture install (Days 6-8)
Wall tile goes up first, then the pan tile or solid surface floor, then grout and sealant. We set the valve trim, showerhead, and any body sprays or hand showers you selected. Frameless glass gets templated after tile is complete, then fabricated offsite, which adds 7 to 10 business days to total project length if you choose that route. Semi-frameless or framed units ship faster.
Stage 5: Final inspection, cleanup, and walkthrough (Day 9-10)
We pull the final plumbing permit closeout if required, run full water pressure and drainage tests, caulk all joints, and walk the finished shower with you. We leave you with care instructions for grout and glass sealant, plus manufacturer warranty cards for fixtures and the shower door.
The Material and Configuration Choices You’ll Actually Make
Every tub-to-shower conversion in North Miami involves a handful of real decisions that affect cost, maintenance, and how the shower feels to use daily. Here’s what we see homeowners weighing:
- Shower pan: prefab acrylic vs. tiled mortar bed. Prefab units run $400-$900, install in hours, and carry manufacturer warranties against leakage, but you’re locked into standard sizes and colors. A custom mortar bed with tile or solid surface costs $1,200-$2,800, takes two days to build and cure, and lets you size the pan exactly to your space. In North Miami’s older homes with out-of-square walls, custom often fits better.
- Wall surround: large-format tile, subway tile, or solid surface panels. Tile gives you design flexibility and holds value in resale, but grout needs annual sealing in Florida’s humidity. Solid surface panels like Swanstone or Corian eliminate grout lines entirely, clean easily, and install faster, though the aesthetic reads more utilitarian. Budget roughly $8-$25 per square foot installed for tile, $12-$30 for solid surface.
- Valve and trim: pressure-balance vs. thermostatic. Pressure-balance valves, standard in most homes, hold temperature when someone flushes a toilet. Thermostatic valves let you set and lock a precise temperature, which matters if you have kids or temperature-sensitive skin. The valve body itself costs $150-$400 more for thermostatic, and you’ll feel the difference every morning.
- Glass enclosure: framed, semi-frameless, or frameless. Framed is the most water-tight and affordable at $600-$1,200. Semi-frameless hits a middle ground around $1,000-$1,800. Frameless runs $1,500-$3,500 depending on glass thickness and hardware finish, but it opens the visual space in a small North Miami bathroom dramatically.
- Curbed vs. curbless entry. A traditional 4- to 6-inch curb contains water reliably and costs nothing extra. Curbless requires sloping the entire bathroom floor toward the drain and often a linear drain upgrade, adding $1,500-$3,000, but it ages-in-place beautifully and reads as more spacious.
What Tub-to-Shower Conversion Costs in North Miami, FL
In North Miami, a tub-to-shower conversion typically costs between $3,500 and $10,000. Here’s what pushes a job toward the low end or the high end:
| Cost Driver | Low-End Scenario | High-End Scenario |
|---|---|---|
| Plumbing location | Keep existing drain and valve | Relocate drain, add body sprays, upgrade supply lines |
| Shower size | Standard 60″ x 30″ tub footprint | Expand to 60″ x 36″ or larger, borrow adjacent space |
| Wall and floor finish | Prefabricated surround and pan | Floor-to-ceiling tile, niche shelving, bench seat |
| Glass enclosure | Framed sliding door | Frameless with heavy glass and custom hardware |
| Permit and code scope | Plumbing fixture replacement only | Triggered structural or flood-elevation upgrades |
Our written estimates include demolition, disposal, all materials we supply, labor, permit fees, and rough and final inspections. What typically isn’t included: bathroom vanity replacement, floor tile outside the shower footprint, or any repair work triggered once walls are opened and we find hidden damage. We flag the most common surprises during the initial walkthrough so you’re not blindsided.
What North Miami’s Older Housing Stock Means for This Job
North Miami’s residential core is packed with 1950s-1970s CBS ranch homes that predate both Miami-Dade County’s post-Hurricane Andrew High-Velocity Hurricane Zone codes and current FEMA flood elevation requirements. Any substantial renovation risks triggering the county’s “50% rule,” which forces full flood-elevation and hurricane-hardening compliance if the improvement cost exceeds half the structure’s assessed value. We’ve seen a modest tub-to-shower conversion balloon into a whole-house code upgrade when the homeowner was already planning an addition or roof replacement in the same permit cycle.
The practical reality: in ZIP 33161, we regularly work on original bathrooms with terrazzo floors sloped toward the tub, galvanized drains, and single-wythe block walls that won’t accept modern recessed valve bodies without careful layout. Miami-Dade inspectors know these houses. When we pull a permit for plumbing relocation, they sometimes flag the existing jalousie windows or missing roof-to-wall straps on the same structure, triggering whole-house hardening requirements the homeowner didn’t budget for. Experienced contractors in North Miami price this possibility into every bid from the start.

Frequently Asked - Tub-to-Shower Conversion in North Miami
Most conversions finish in 5 to 10 working days, with frameless glass adding another 7 to 10 calendar days for fabrication. If Miami-Dade inspection schedules are backed up or we discover galvanized drain lines that need replacement, add 2 to 3 days. Call (844) 665-0162 and we’ll give you a realistic timeline based on your specific bathroom layout.
Yes, Miami-Dade requires a plumbing permit for any tub-to-shower conversion that involves drain or valve work, which is nearly all of them. If you’re keeping the exact same footprint and only swapping a tub for a shower of identical dimensions, some jurisdictions allow a simpler fixture-replacement permit, but we always verify with the county before starting. We pull permits and schedule inspections as part of our standard process.
Often yes, and that’s the most budget-friendly path. If your existing tub drain centers at 14 to 16 inches from the back wall and the valve height works for a showerhead, we can install a shower pan and enclosure without relocating rough plumbing. In North Miami’s older homes with terrazzo floors, keeping the drain where it is also avoids the mess and cost of cutting and patching stone flooring.
The lowest-cost path is a prefab acrylic shower surround and pan in a standard size, keeping existing plumbing locations, with a framed or semi-frameless door. That combination typically lands near the $3,500 to $5,000 range in North Miami. The trade-off is less design flexibility and a shorter lifespan than tile, but for a rental property or a quick functional update, it’s a sound choice.
We warranty our workmanship for one year on all tub-to-shower conversions. Fixtures carry their own manufacturer warranties, typically lifetime on cartridges and finish for brands like Moen, Delta, and Kohler. Shower doors usually carry a 3 to 5 year warranty depending on the manufacturer. We register all warranty paperwork with you at final walkthrough so there’s no paperwork hunt later.
