Tub-to-Shower Conversion in Goulds, FL: What It Costs and How Long It Takes
A tub-to-shower conversion in Goulds runs $3,500-$10,000 for most homes, with the job typically finished in 5 to 10 working days depending on whether plumbing stays put or gets relocated. We handle the demo, waterproofing, rough plumbing, tile or surround installation, and final fixture connections.

How We Approach a Tub-to-Shower Conversion Start to Finish
We’ve done enough of these in South Miami-Dade to know where the surprises hide. Here’s how we sequence the work so you know what to expect and when you’ll need to make decisions.
Day 1: Demo and discovery. We strip out the tub, surround, and adjacent drywall or backer board to expose the plumbing rough-in and framing. In Goulds, this is where we find out whether your home has original galvanized supply lines from the 1960s or 1970s, or if a previous owner already updated to copper or PEX. If the supply valves are original, we’ll flag replacement now rather than after the walls are closed. This stage takes one day and generates the most debris.
Day 2-3: Plumbing and structural decisions. If you’re keeping the drain and valve locations, we verify slope and pressure. If you’re moving the drain from under the tub to a center-floor shower drain, or switching from a tub-spout valve to a thermostatic shower system, this is when we open the slab. In Goulds, that shallow Miami oolitic limestone we hit just below the concrete means core drilling or light jackhammering, never simple trenching. You’ll decide on valve height, showerhead configuration, and any body-spray locations by end of day 2.
Day 4-6: Waterproofing and prep. We install cement backer board or foam shower pan systems, apply liquid or sheet membrane waterproofing, and flood-test the pan for 24 hours. Miami-Dade inspectors require visible waterproofing documentation for permit closeout, so we photograph every layer. If you’ve chosen a solid surface surround rather than tile, we template and order now if it wasn’t pre-measured.
Day 7-9: Finish installation. Tile or surround goes up, grout or sealant cures, fixtures get set. We install glass doors or curtain rods last, after everything else is clean. Caulk needs 24 hours minimum before use.
Day 10: Final inspection and walkthrough. Miami-Dade plumbing inspectors verify trap seal, venting, and pressure. We run through fixture operation, cleaning protocols, and warranty paperwork with you.
Most of our Goulds clients make their material choices during our first site visit so we can order tile, glass, and fixtures before demo starts. Delays almost always come from indecision on tile or a backordered valve, not from the build itself.
The Choices That Shape Your Shower
Every tub-to-shower conversion forces a handful of real decisions. Here’s where your money goes and what each option gives you.
- Shower base: prefab acrylic vs. tiled mud pan. Acrylic bases run $400-$900 installed and work fine for standard 60-by-30-inch openings. A custom mud pan with tile runs $1,200-$2,500 but lets you size the shower exactly, add a bench, or create a curbless entry. In Goulds, curbless pans need extra slope precision because that high water table means any drainage failure shows up fast.
- Walls: fiberglass surround, solid surface, or tile. Fiberglass three-piece surrounds are the budget path at $600-$1,200. Solid surface like Silestone or Caesarstone slabs run $2,000-$4,500 and eliminate grout lines entirely. Tile gives you the most design range but demands sealed grout maintenance in South Florida’s humidity. We see mold-resistant epoxy grouts hold up better here than standard cement grout.
- Valve and fixtures: pressure-balance vs. thermostatic. Pressure-balance valves, common in older Goulds homes, guard against scalding when someone flushes a toilet. Thermostatic valves let you set exact temperature and run multiple outlets. Moen and Kohler both make reliable thermostatic lines; we spec them for clients adding body sprays or rain heads.
- Glass enclosure: framed, semi-frameless, or frameless. Framed is cheapest and most forgiving of out-of-square walls. Frameless needs precise walls and costs 40-60% more, but opens the visual space in a small bathroom. In hurricane country, we only use tempered glass with proper Miami-Dade NOA anchors, never generic hardware.
- Drain location: keep existing or relocate. Keeping the drain saves $800-$1,500 in slab work. Moving it to center-floor improves aesthetics and drainage but requires concrete cutting and permit amendment.

Why Goulds Homes Make This Job Different
Goulds sits in Miami-Dade’s High Velocity Hurricane Zone, and that matters even for interior work. Any exterior wall penetration for new venting, exhaust fans, or window modifications needs Miami-Dade NOA-approved materials and fasteners. We’ve seen out-of-area contractors spec standard hardware that fails inspection here, adding weeks to permits.
The housing stock tells its own story. Most Goulds homes we work on are 1950s-1970s concrete block structures built for agricultural families, with original bathrooms barely larger than the tub itself. Those tight footprints mean we often steal space from adjacent closets or reconfigure door swings to get a comfortable 36-by-36-inch shower minimum. The post-Andrew rebuilt homes nearby have updated plumbing and more generous layouts, but even there we check whether previous owners did permitted work or shortcutted with handyman-grade waterproofing.
That shallow water table, just 2-4 feet below grade, means any slab work stays shallow and precise. We can’t trench deeply for drain relocation, so we core through the limestone carefully and verify slope with a laser level. And after named storms, permit offices back up and material suppliers surge. We schedule Goulds jobs with hurricane season in mind, building buffer into ordering and inspection timing.
Homeowners here often pair interior updates with exterior hardening. If you’re also considering Metal Roofing in Goulds or Tile Roofing in Goulds, our Bathroom Remodeling crew coordinates with the roofing team so you’re not juggling separate contractors across Goulds permit schedules.

Frequently Asked - Tub-to-Shower Conversion in Goulds
Most conversions finish in 5 to 10 working days. The range depends on whether we relocate plumbing, encounter original galvanized pipe that needs replacement, or wait on Miami-Dade inspections during busy periods. Call (844) 665-0162 and we’ll give you a firm timeline after seeing your bathroom.
Yes. Miami-Dade County requires a plumbing permit for any drain or supply line modification, and most conversions trigger this. We pull the permit, schedule inspections, and ensure all materials carry the required NOA documentation for HVHZ compliance. Homeowners who skip permitting risk failed resale inspections and insurance complications.
Often yes, if the existing drain location works for a shower base and the valve height reaches code minimums. Keeping everything in place saves $800-$1,500 and shortens the timeline by 2-3 days. We’ll verify this during your free estimate by checking your rough-in dimensions against the shower system you want.
The budget path uses a prefab acrylic shower base, three-piece fiberglass surround, pressure-balance valve, and a shower curtain instead of glass. That typically lands near $3,500-$4,500 if your plumbing stays put and we find no hidden rot or pipe replacement. We don’t recommend cutting waterproofing corners; failed pans cost more than doing it right the first time.
We warranty our waterproofing and plumbing workmanship, and the fixtures carry their manufacturer warranties. Kohler and Moen valves typically include lifetime limited warranties on finish and function; Silestone and Caesarstone surfaces carry their own material guarantees. We register products for you and keep documentation on file.
