Tub-to-Shower Conversion in Miami Springs: What It Costs and How Long It Takes
A tub-to-shower conversion in Miami Springs typically runs $3,500-$10,000 and takes 5-10 working days from demo to final inspection. Most homeowners call us at (844) 665-0162 when they’re tired of stepping over a tub they never use, or when the original 1950s fiberglass unit has cracked at the drain. We handle the plumbing relocation, waterproofing, tile or surround installation, and all Miami-Dade permitting so you’re not coordinating three separate trades.
How We Handle Tub-to-Shower Conversion Start to Finish
Every conversion follows the same sequence, though the timeline stretches or compresses based on whether we’re working with original galvanized plumbing or a more recent copper setup.
Day 1: Demo and rough assessment. We remove the tub, surround, and valve assembly, then expose the wall cavity to assess what’s behind it. In Miami Springs, this is where we often find single-wythe concrete block walls with no moisture barrier, or terrazzo floors that extend under the tub footprint. We photograph everything and confirm whether the drain line needs relocation. Homeowner decision needed today: keep the existing footprint or expand it?
Days 2-3: Plumbing and structural prep. If we’re moving the drain from under the tub to the center or back wall for a curbless entry, this is when our plumber roughs in new PVC. We also sister any rotted studs, add hurricane strapping if the original fastening is inadequate, and install a pre-sloped shower pan or mud-bed base depending on your tile choice. Homeowner decision needed: pan material (acrylic, composite, or traditional mud-bed) and curb height.
Days 4-5: Waterproofing and drying. We apply liquid membrane or sheet membrane to all wet-area surfaces, extending 6 inches beyond the shower footprint on floors. In Miami Springs, the salt air and summer humidity mean we don’t rush this stage. Membrane needs 24 hours minimum to cure before tile. Homeowner decision: grout color and whether to add a niche or bench.
Days 6-8: Tile or surround installation and trim. For tile showers, we set field tile, then accent or border tile, then grout and seal. For acrylic or solid-surface surrounds, installation is faster but requires precise templating. We install the valve trim, showerhead, and glass enclosure hardware. Homeowner decision: final hardware finish (brushed nickel, matte black, chrome).
Days 9-10: Glass, final plumbing, and inspection. We hang the frameless or semi-frameless door, run pressure tests, and call for Miami-Dade plumbing and building final inspections. If your home sits in one of the original 1920s-1940s sections near Curtiss Parkway or Deer Run, we sometimes need to coordinate with the city on older electrical panel clearances. Homeowner: you’re using your new shower by day 10 in most cases.
The Options You’ll Choose Between for Your Miami Springs Conversion
- Shower base: acrylic insert vs. composite solid-surface vs. traditional mud-bed with tile. Acrylic runs $400-$900 installed, lasts 15-20 years, and works well for quick turnarounds. Composite (Swanstone, Kohler Choreograph) hits $1,200-$2,500, feels more substantial, and resists staining better. Mud-bed with porcelain or ceramic tile starts around $1,800 for the base alone but gives you any size or slope configuration, critical if you’re planning a curbless aging-in-place design.
- Walls: fiberglass surround panels vs. tile vs. solid-surface sheets. Three-piece fiberglass surrounds are the budget play at $600-$1,200, but the seams collect grime and the finish dulls in 8-10 years. Tile (ceramic, porcelain, or natural stone) runs $1,500-$5,000 depending on material and pattern complexity. Solid-surface sheets like Corian or Swanstone hit $2,000-$4,000, are grout-free, and clean easily, but limit you to manufacturer colors.
- Plumbing configuration: keep existing vs. relocate drain and valve. Keeping the tub footprint saves $800-$1,500. Moving the drain across a slab-on-grade floor (common in 1950s-1970s Miami Springs ranch homes) means cutting concrete, which adds $1,200-$2,800 and a day of work. Moving the valve height for a rainhead or handheld adds $300-$600.
- Glass enclosure: framed sliding door vs. semi-frameless vs. frameless. Framed sliders start around $600. Semi-frameless pivot doors run $900-$1,400. True frameless with 3/8-inch tempered glass and minimal hardware starts at $1,800 and climbs with width, custom cuts for knee walls, or special coatings for hard water.
- Fixture grade: builder-basic Delta or Moen vs. mid-tier Kohler or Grohe vs. luxury Brizo or Rohl. Basic pressure-balance valves with a simple showerhead run $150-$300. Thermostatic valves with separate volume and temperature controls, plus a handheld and rainhead, push $600-$1,400. For the Mediterranean Revival homes near Miami Springs‘ historic core, we often spec oil-rubbed bronze or unlacquered brass to match original hardware elsewhere in the home.

A written estimate from us includes demo, disposal, rough plumbing, pan and wall installation, waterproofing, tile or surround labor, fixture setting, glass enclosure, and permit fees. What it typically doesn’t include: bathroom vanity replacement (that’s a separate scope), electrical upgrades if your panel won’t support a new exhaust fan heater combo, or structural repairs beyond standard stud sistering. If you’re considering this as part of a full Bathroom Remodeling in Miami Springs project, we price the conversion as a line item within the broader scope so you’re not paying twice for demo or permit fees.
Our Bathroom Remodeling crew sees the most sticker shock when homeowners assume they can keep everything where it is, then discover the original tub drain is 18 inches from where a modern shower base needs it. We catch that in our first site visit, not on day two of demo.
What Miami Springs Homes Specifically Do to This Job
Miami Springs presents a combination you don’t find in neighboring Hialeah or Doral. The city’s origins as Glenn Curtiss’s 1920s planned community mean our Metal Roofing in Miami Springs crews and bathroom teams alike are working inside 90-year-old Mediterranean Revival homes with single-wythe concrete block walls, terrazzo floors, and original clay barrel-tile roofs. Those block walls have no cavity for plumbing, so drain lines often run surface-mounted or through carefully core-drilled penetrations that need precise sealing against the salt-laden air rolling in from Biscayne Bay.
The post-war ranch infill on streets like Ludlam Drive and Westward Drive brings a different problem: corroded galvanized supply lines and 100-amp electrical services that can’t handle a modern thermostatic valve plus exhaust fan plus heated floor. We quote those upgrades separately so you’re not surprised mid-project.
Permitting runs through Miami-Dade County, not a city office, which actually streamlines things. However, if your conversion involves any structural modification to an exterior wall, or if you’re in a two-story home where we’re plumbing near the roofline, we have to account for Miami Springs’s position under MIA’s Part 77 airspace. That means FAA Form 7460-1 filing for any construction exceeding certain heights, a step most South Florida contractors never touch outside airport-adjacent municipalities. For a standard tub-to-shower conversion it’s rarely triggered, but we’ve seen it come up when homeowners want to vault a ceiling or add a clerestory window as part of a larger bath reconfiguration. Filed late, that form can add weeks. We check it before we price.
The high water table at roughly 9 feet elevation also means any slab cutting for drain relocation needs same-day backfill and compaction vigilance. Summer thunderstorms don’t wait for your concrete to set. And every penetration through that slab gets sealed to Florida Building Code Section 1609 standards for wind-driven rain resistance. Homeowners often pair exterior envelope work with interior renovations, so we coordinate with our Tile Roofing in Miami Springs team when a full-property project makes sense.

Frequently Asked - Tub-to-Shower Conversion in Miami Springs
Most conversions take 5-10 working days from demo to final inspection. Relocating plumbing across a slab, custom tile patterns, or waiting on a frameless glass order can stretch that to two weeks. We schedule glass templating during the waterproofing phase so fabrication happens in parallel, not serial. Call (844) 665-0162 and we’ll walk through your specific timeline after a quick site visit.
Yes. Miami-Dade County requires a plumbing permit for drain relocation and a building permit for any structural modification, including moving walls or changing the wet-area footprint. We pull both as part of our standard process. The county inspects rough plumbing before close-in and final plumbing after fixture setting. If your home is in a historic district or has HOA oversight near the Circle area, we coordinate that layer too.
Often yes, if the existing drain location works for your chosen shower base and you’re keeping the same approximate footprint. Many 1950s-1970s Miami Springs ranch homes have the tub drain centered, which aligns with standard 48-inch or 60-inch shower bases. The valve height may still need adjustment for a modern rainhead or handheld combo. We verify drain alignment and valve accessibility during our free estimate so you know before demo starts.
The biggest cost drivers are drain relocation across slab, wall material upgrades from fiberglass to full tile, and fixture grade. Homes on the historic grid near Curtiss Parkway or Oakwood Drive often need additional wall prep because single-wythe block requires specialized fastening and moisture management. Post-war ranches with galvanized plumbing may need supply line replacement. We itemize these in your written estimate so you see exactly what moves the number.
We warranty our workmanship on waterproofing, tile installation, and plumbing connections. Manufacturer warranties cover your shower base, fixtures, and glass hardware. We use name-brand products from our curated roster, including options from Kohler, Moen, and Delta, so replacement parts are available through standard distribution. We don’t lock you into proprietary systems you can’t service in five years. For warranty specifics on your selected materials, ask during your estimate walkthrough.
