Tub-to-Shower Conversion in Miami Lakes: What It Costs and How Long It Takes
A tub-to-shower conversion in Miami Lakes typically runs $3,500-$10,000 and takes 5-10 working days from demo to final inspection. Most homeowners in 33014 call us because their original 1970s or 1980s fiberglass tub surround has cracked, the valve behind the wall is leaking, or they’re done climbing over a 14-inch tub rim. Call (844) 665-0162 and we’ll walk your specific layout, give you a written estimate, and flag anything that’ll push your job toward the higher end before we start.
How We Handle a Tub-to-Shower Conversion Start to Finish
We break this job into five distinct stages so you know what’s happening, what we’re waiting on, and what you need to decide before we can move forward.
Stage 1: Site measure and scope lock (Day 1, 2-3 hours)
Raymond Estevez or our lead estimator visits your home, photographs the existing conditions, and checks three things that kill schedules later: whether your tub is a standard 60-by-30-inch alcove or a custom dimension, whether the drain sits center, left, or right of the valve, and whether your walls are original plaster-and-lath, drywall over furring, or concrete block with furring strips. In Miami Lakes, that last question matters more than you’d think. The Graham Companies’ 1960s-1980s CBS builds often have block walls with irregular furring, which changes how we waterproof and how thick your finished wall will end up. You’ll decide at this stage: keep the footprint and drain location, or move either one. Keeping both saves roughly $1,200-$2,800.
Stage 2: Demo and rough inspection (Days 2-3)
We remove the tub, surround, valve, and drain assembly down to the studs or block. If your home’s on a post-tensioned slab - common in that South Florida building era - we never cut concrete for drain relocation without a structural engineer’s GPR scan first. Severing a tensioned cable turns a $6,000 bathroom job into a $15,000 structural repair. We expose the plumbing, verify venting is up to current Miami-Dade code, and call for rough inspection. Miami-Dade inspectors typically book 24-48 hours out for residential plumbing roughs in our area.
Stage 3: Waterproofing and prep (Days 4-5)
This is where quality separates out. We install a bonded waterproof membrane system (liquid-applied or sheet membrane, depending on your tile selection) that carries a Miami-Dade NOA for HVHZ compliance. The membrane has to cure 24 hours before tile. If you’ve chosen a solid-surface shower pan and wall panels instead of tile, we set the pan on a mortar bed, level it, and let it set overnight. You’ll have already picked your fixtures by now - we don’t open walls twice because a valve trim arrived late.
Stage 4: Finish installation (Days 6-8)
Tile setters work top-to-bottom, grouting on day two of this stage. For acrylic or solid-surface systems, we panel the walls and seal joints with manufacturer-specified sealant. Glass enclosure measurements happen here, but the actual glass goes in after final inspection - typically 10-14 days lead time for custom frameless, 3-5 days for semi-frameless. You’ll do a walk-through with our foreman before we call for final.
Stage 5: Final inspection and glass (Days 9-10, plus glass lead time)
Miami-Dade final plumbing inspection verifies valve operation, drain flow, and venting. Once we pass, the glass crew returns for enclosure installation. We do a full clean, caulk all perimeter joints with mold-resistant silicone, and hand you your material warranties and care instructions.
The Material and Layout Choices You’ll Actually Make
Every tub-to-shower conversion in Miami Lakes forces a decision at each of these points. Here’s where the money goes, and what you gain or lose:
- Shower pan: tiled vs. solid-surface vs. acrylic. Tiled pans with a linear drain look sharp and cost $800-$1,400 in materials, but the grout joints need resealing every 12-18 months in South Florida’s humidity. Solid-surface pans (corian-type, cast from a single mold) run $1,200-$2,200, have zero grout, and clean with standard bathroom cleaner. Acrylic pans are $400-$900, install fast, and work fine for rental properties or tight budgets, but they flex slightly and feel less substantial underfoot.
- Wall finish: ceramic or porcelain tile vs. large-format porcelain vs. solid-surface panels. Standard 12-by-24 ceramic tile with a running bond pattern is $3-$8 per square foot and gives you the most design flexibility. Large-format porcelain (24-by-48 or bigger) at $9-$18 per square foot minimizes grout lines - a real advantage in humid Miami Lakes bathrooms where mildew finds every joint. Solid-surface panels from brands like Swanstone or Kohler Choreograph are $2,000-$4,500 installed, go up in a day, and never need grout maintenance, but you’re limited to their color palette.
- Valve and trim: pressure-balance vs. thermostatic. Pressure-balance valves (most common, $180-$400 for trim and rough) prevent scalding if someone flushes a toilet. Thermostatic valves ($450-$900) hold temperature within one degree and let you set a maximum - worth it if you have kids, elderly family, or just hate fiddling with the handle. We stock Moen, Delta, and Grohe rough-ins; you pick the trim that matches your aesthetic.
- Glass enclosure: framed, semi-frameless, or frameless. Framed sliders are $600-$1,200, functional but dated. Semi-frameless at $1,100-$2,000 gives a cleaner look with a thin metal header. True frameless with 3/8-inch tempered glass and minimal hardware is $2,200-$4,500 and demands precise wall plumbness - something we verify in Stage 1, because out-of-plumb block walls in older Miami Lakes homes can add $400-$800 in custom glass cutting.
- Drain location: keep existing vs. relocate. Keeping your drain where it sits avoids concrete cutting, plumbing rough changes, and inspection complications. Relocating even 12 inches on a slab foundation in 33014 means a structural review, potential GPR scanning, and $1,500-$3,000 in additional labor and materials. We only recommend it when the existing location forces an awkward shower layout.
What Tub-to-Shower Conversion Costs in Miami Lakes, FL
In Miami Lakes, tub-to-shower conversion costs $3,500-$10,000. Here’s what moves you through that range:
| Cost Driver | Low-End Scenario | High-End Scenario |
|---|---|---|
| Shower footprint and layout | Keep existing 60″ alcove, drain in place | Expand to 72″ or relocate drain on slab |
| Wall and pan materials | Acrylic surround and pan | Large-format porcelain tile, linear drain, mud-set pan |
| Plumbing complexity | Replace valve only, no vent changes | Reroute supply, add vent, upgrade to thermostatic |
| Glass enclosure | Framed bypass door | Custom frameless with heavy glass |
| Structural surprises | Clean demo, sound studs or furring | Post-tension slab scan, block wall remediation, tie-beam exposure |
Our written estimates include demo, disposal, rough and finish plumbing, waterproofing, wall and pan installation, basic fixtures, and final inspection coordination. What’s typically separate: the glass enclosure (we measure and coordinate, but glass shops bill direct), any electrical work like adding a recessed shower light or exhaust fan upgrade, and tile or solid-surface material if you source your own. If your job is part of a full Bathroom Remodeling in Miami Lakes, we bundle the line items and schedule trades to avoid redundant mobilization fees.
Why Miami Lakes Homes Make This Job Different
The master-planned community the Graham Companies built here in the late 1960s through mid-1980s means we’re working on a remarkably uniform housing stock - and that uniformity creates predictable complications. Nearly every tub we’re pulling is original to a 1970s or 1980s CBS build with block walls, furring strips, and a post-tensioned or conventional slab sitting 1-2 feet above a water table fed by the town’s chain of man-made lakes. That proximity to open water doesn’t flood your bathroom, but it means any slab penetration for drain relocation stays wet longer, requires better compaction if we backfill, and occasionally forces us to pump water during excavation.
The bigger factor is Miami-Dade’s High-Velocity Hurricane Zone code. Every product we install - waterproofing membrane, backer board, exhaust fan, even the adhesive behind your tile - needs a Miami-Dade Notice of Acceptance. Contractors working just across the county line in Broward don’t always stock HVHZ-approved materials, which is why we keep our Miami Lakes jobs on our own procurement schedule rather than relying on spot deliveries. We’ve also learned to inspect the tie-beam condition above bathroom walls in these aging CBS structures; if your remodel exposes a tie-beam that needs reinforcement to maintain the roof-to-wall connection, we’ll flag it early so it doesn’t become a change-order surprise.
Homeowners in Miami Lakes often tackle exterior projects alongside interior updates - the same HVHZ compliance logic applies. If you’re already budgeting for a tub-to-shower conversion and your roof is past its service life, we’ve found it efficient to coordinate material deliveries. Some clients pair this work with Metal Roofing in Miami Lakes or Tile Roofing in Miami Lakes to consolidate permitting and inspection schedules under one contractor relationship.

Frequently Asked - Tub-to-Shower Conversion in Miami Lakes
Most conversions take 5-10 working days, plus 3-14 days for custom glass after final inspection. Miami-Dade rough and final inspections add 1-2 days each to the schedule, and we don’t install glass until we pass final. Call (844) 665-0162 and we’ll give you a firm timeline based on your specific layout and material choices.
Yes. Miami-Dade County requires a plumbing permit for any tub removal and shower valve replacement, and a building permit if you’re moving walls or drains. We pull permits as part of our standard process and coordinate inspections so you’re not waiting at home for the inspector. The permit cost is typically included in our estimate.
Usually, yes. If your existing drain is centered or near-centered under a standard 60-inch tub, we can install a shower pan that accepts the current drain location and swap the tub valve for a shower valve using the same supply lines. This keeps the job at the lower end of our $3,500-$10,000 range. We confirm this in our initial site measure.
Cutting into a post-tensioned slab without a GPR scan, then severing a tension cable. Miami Lakes’s concentrated 1970s-1980s building boom means these slabs are more common here than in markets with varied construction eras. We always scan before cutting, which adds $350-$600 but prevents a $10,000+ structural failure. Other common surprises: non-standard tub dimensions that require custom pan fabrication, and block walls far enough out of plumb that frameless glass needs custom cutting.
We warranty our workmanship for two years on waterproofing, plumbing connections, and installation. Manufacturer warranties cover your fixtures (typically lifetime on cartridge, 5-10 years on finish), your shower pan or tile system (10 years to lifetime depending on product), and your glass enclosure (3-5 years on hardware, lifetime on tempered glass). We register all warranties in your name and leave you the documentation.
