Tub-to-Shower Conversion in Tamiami, FL: What It Costs and How Long It Takes
A tub-to-shower conversion in Tamiami replaces your existing bathtub with a dedicated shower enclosure, typically taking 5 to 10 working days depending on whether plumbing stays put or gets relocated. Most homeowners in the 33184 ZIP code pay between $3,500 and $10,000, with the final number hinging on three decisions you’ll make before we swing a hammer: enclosure type, fixture grade, and whether the drain and valve locations move. Call (844) 665-0162 and we’ll walk through those choices on a free on-site estimate.
How We Handle a Tub-to-Shower Conversion Start to Finish
We’ve done enough of these in Tamiami’s 1970s-1990s CBS homes to know where the surprises hide. Here’s the actual sequence, with the decisions you’ll need to make at each stage.
Day 1: Demo and Discovery
We strip the tub, surround, and any water-damaged substrate. In Tamiami’s older stock, we often find the original tub sat on a mortar bed poured directly over that thin oolitic limestone slab, sometimes with no proper waterproofing membrane behind decades-old tile. This is the moment of truth: if the wall framing behind the surround is sound and the drain location works for your new layout, we stay on schedule. If the limestone has channelled moisture into adjacent block walls, we stop, document, and call you with photos before proceeding. You’ll decide today whether to relocate the drain or keep it where it is.
Days 2-3: Plumbing and Rough-In
If you’re keeping the existing drain and valve locations, we cap, test, and move to prep. If we’re moving plumbing - say, converting a 60-inch tub to a 48-inch shower to steal space for a linen niche - this is when our licensed plumber reroutes drain lines through that stubborn Miami limestone. The shallow water table in Tamiami means we can’t just core freely; we map the slab, use vacuum extraction to keep the work zone dry, and pressure-test every joint before closing it up. You’ll confirm your fixture heights and any body-spray locations today.
Days 4-5: Pan, Walls, and Waterproofing
We set the shower pan - either a prefab acrylic base or a site-poured mud pan with topical waterproofing - and install cement board or foam wall panels. In Tamiami’s humid climate, we spec vapor-retardant assemblies behind every surface, not just tile. You’ll choose your wall material now if you haven’t already: large-format porcelain, subway ceramic, solid surface panels, or a composite surround. Each has different lead times, so this decision affects whether we finish on day 8 or day 12.
Days 6-8: Tile or Panel Installation and Grout
Tile crews work methodically here; rushed grout work in South Florida’s humidity breeds mold behind the walls within two years. We use epoxy grout on floor pans and polymer-modified grout on walls, with expansion joints every 8 feet. If you selected a Kohler Choreograph wall system or similar solid surface, installation moves faster - often a single day. You’ll do a walkthrough with our lead carpenter to confirm layout, niche placement, and any accent strip positioning before we set the final row.
Days 9-10: Glass, Fixtures, and Final Inspection
We install your glass enclosure - framed, semi-frameless, or frameless - and set the valve, showerhead, and any hand-shower or thermostatic controls. Then we pressure-test, flood-test the pan for 24 hours, and call for Miami-Dade’s plumbing inspection if the permit requires it. You’ll receive a photo packet of the waterproofing layer, a copy of the inspection sign-off, and our workmanship warranty documentation.
The Options You’ll Choose Between for Your Tamiami Conversion
- Shower base: prefab acrylic vs. site-built mud pan. Acrylic runs $400-$900 installed, locks you into standard sizes, and feels slightly hollow underfoot. A mud pan with waterproofing membrane adds $1,200-$2,800 but lets us build any dimension, pitch the floor precisely, and pair with any tile you want. For Tamiami’s older homes with out-of-level floors, the mud pan is usually worth it.
- Wall surround: composite panels vs. tile vs. solid surface. Composite surrounds (Swanstone, similar) run $1,500-$3,500 all-in, install fast, and clean easily - fine for a rental or tight timeline. Tile ranges from $2,500 for basic ceramic to $6,000+ for large-format porcelain with epoxy grout. Solid surface like Kohler Choreograph or Swanstone solid panels splits the difference at $2,800-$4,500, with no grout lines to maintain in this humidity.
- Fixture grade: builder-basic vs. mid-spec vs. premium. Moen Chateau or similar at $150-$300 per valve gets you 5-7 years of reliable service. Step up to Moen’s M-CORE or Kohler’s Purist lines at $400-$800 for better cartridge longevity and finish warranties that hold up to Tamiami’s salt-laden air. Thermostatic valves and multi-function diverters push past $1,200 but eliminate temperature swings when someone flushes elsewhere in the house.
- Glass enclosure: framed, semi-frameless, or frameless. Framed sliders start around $600; semi-frameless hits $1,200-$1,800; true frameless with 3/8-inch glass and minimal hardware runs $2,000-$3,500. In Tamiami’s tight bathrooms, a frameless door on a fixed panel can make a 32-inch shower feel significantly larger.
- Plumbing relocation: keep it or move it. Keeping existing drain and valve locations saves $800-$2,000 and 1-2 days. Moving the drain across the slab means cutting through that oolitic limestone, adding dewatering time, and extending the schedule. We only recommend it when the layout gain is substantial - a true walk-in feel, space for a bench, or accessibility requirements.

What Tamiami’s Conditions Mean for This Specific Job
Tamiami’s housing stock shapes every tub-to-shower conversion we do here. The CBS homes built during the 1970s-1990s westward push from Miami proper typically have original bathrooms with cast-iron or steel tubs set in mortar beds, often with galvanized drain lines that have corroded internally. When we cut the slab to access that drain, we’re working 12-18 inches above oolitic limestone that’s hard enough to stall standard bits - and porous enough that groundwater seeps in continuously during the dry season, let alone after a June afternoon deluge.
That shallow water table means our crews run dewatering pumps on nearly every slab-cut job in the 33184 ZIP, a line item contractors from outside South Florida routinely miss in their bids. The original stucco behind these tub surrounds also tends to be single-coat over wire lath, with no drainage plane; we’ve opened walls to find rebar corrosion in the block cores from years of slow moisture migration. We address it when we find it, not with upsell pressure, but because a shower conversion that traps water in those walls fails within three years in this climate.
Permitting runs through Miami-Dade County’s Building Department, and any plumbing relocation triggers a rough-in inspection before close-up. For homes in communities along the Tamiami Trail corridor, HOA architectural review may add 2-4 weeks to the front end; we handle the submittal package, but homeowners should check their association’s published guidelines for fixture finish restrictions or contractor insurance requirements.
Homeowners in Tamiami often pair interior work with exterior upgrades, and our Metal Roofing in Tamiami and Tile Roofing in Tamiami crews coordinate timing so you’re not juggling multiple contractors across the property. Our Tamiami service area covers the full 33184 ZIP and adjacent unincorporated pockets west to the Everglades boundary.

Frequently Asked - Tub-to-Shower Conversion in Tamiami
Most conversions finish in 5 to 10 working days, with plumbing relocation, custom tile work, or Miami-Dade inspection scheduling pushing toward the longer end. If your HOA requires pre-approval, add 2-4 weeks before we start demo. Call (844) 665-0162 and we’ll confirm timeline based on your specific layout and material choices.
Yes, if any plumbing changes or structural modifications are involved - which covers nearly every conversion we do, since even swapping a tub for a same-size shower typically requires a new pan and updated drain connection. Groundwork pulls the Miami-Dade permit and schedules inspections as part of our standard process. Call (844) 665-0162 and we’ll verify whether your specific scope triggers permit requirements.
Often yes, and keeping the existing drain and valve locations saves roughly $800-$2,000 and 1-2 days. The constraint is that your new shower must align with those fixed points - usually a 60-inch width with the drain at the tub’s original location. We evaluate this during our free on-site estimate; call (844) 665-0162 to schedule.
The biggest cost drivers are plumbing relocation, wall material choice, and what’s hidden behind the existing tub. Homes near the Tamiami Trail with original 1970s-1980s construction often need corroded drain replacement and moisture-damaged substrate repair, which adds $1,000-$3,000 to the base scope. Call (844) 665-0162 for a written estimate that accounts for your specific conditions.
We warranty our workmanship on shower conversions, and every fixture and material carries its own manufacturer warranty - Kohler and Moen valves typically carry lifetime finish warranties, while glass enclosures range from 1 to 10 years depending on hardware grade. We document every warranty and registration requirement in your closeout packet so you’re not hunting paperwork later.
