Tub-to-Shower Conversion in Ojus, FL: What It Costs and How Long It Takes
A tub-to-shower conversion in Ojus typically runs $3,500-$10,000 and takes 5-10 business days from demolition to final inspection. The job removes your existing bathtub, reworks the wet-area envelope, and installs a shower system sized to your bathroom’s footprint and your chosen material grade. Call (844) 665-0162 and we’ll walk your exact layout, check your existing plumbing configuration, and give you a written estimate with line-item pricing before any work starts.
How We Approach a Tub-to-Shower Conversion Start to Finish
We’ve done enough of these in Ojus to know where the surprises hide. The process breaks into five stages, and at each one there’s a decision point that locks in your cost and timeline.
Stage 1: Demo and Subfloor Exposure (Day 1)
We pull the tub, surround, and any tile backer down to the studs and subfloor. This is when we find out what we’re really working with: cast iron tubs in these 1960s Ojus ranches weigh 300+ pounds and often require cutting to get through the doorway. If the subfloor’s been wet for years, we expose it now and mark replacement areas. You’ll decide here whether to patch the existing floor or replace the full wet-area subfloor, a choice that typically adds $400-$900 but eliminates future flex and tile crack issues.
Stage 2: Plumbing Rough-In and Drain Repositioning (Days 2-3)
Most tub drains sit 12-14 inches from the wall; shower drains center at the threshold or move to a linear trench position. If you’re keeping the drain location, we save a day and roughly $600-$1,200 in plumbing labor. If you want a curbless entry or a larger shower footprint, we relocate the drain, which means breaking concrete in slab-on-grade homes, the standard construction method throughout Ojus’s 1950s-1970s housing stock. The shallow Miami Limestone beneath these slabs, sitting just 1-3 feet below grade, can turn a simple jackhammer job into a rock-cutting operation that requires specialized equipment most out-of-area crews don’t carry.
Stage 3: Waterproofing and Structural Prep (Days 3-4)
We install a bonded waterproof membrane system, not builder-grade plastic sheeting. In Ojus’s humid climate with its chronically high water table, vapor management isn’t optional, it’s what keeps your walls from becoming a mold reservoir in year three. You’ll choose between a traditional pan liner with pre-slope or a bonded waterproofing assembly. The bonded system costs 15-20% more upfront but eliminates the weak points where liners fold and fail.
Stage 4: Tile or Panel Installation and Fixture Mounting (Days 5-8)
This is where your material choices show up in the schedule. Large-format porcelain or natural stone takes longer to lay level and demands more precise substrate prep. Acrylic or solid-surface wall panels go up in a day and a half. You’ll also lock in your valve trim, showerhead, and any body-spray or handheld configurations. We spec Kohler pressure-balancing valves as our baseline, Moen thermostatic if you want precise temperature control for multi-head setups.
Stage 5: Glass, Final Trim, and County Inspection (Days 9-10)
Frameless glass requires templating after tile is set, so there’s a 48-72 hour fabrication lag. If you’re on a tight timeline, a semi-frameless or framed slider cuts that wait. Because Ojus is unincorporated Miami-Dade County, your permit pulls through the county Building Department, not a city office. The inspection queue is county-wide, and we’ve learned which filing codes and fee schedules apply to tub-to-shower conversions versus full bathroom gut jobs. Contractors who don’t work this jurisdiction regularly often mis-file, adding weeks to what should be a same-week inspection.
The Material and Configuration Choices That Drive Your Shower
Every tub-to-shower conversion in Ojus forces a series of either/or decisions. Here’s how we frame them for homeowners:
- Shower base: Standard acrylic pan vs. tiled mud set. Acrylic runs $800-$1,500 installed, comes in stock sizes, and carries a 10-year manufacturer warranty. A custom mud-set pan with waterproofing and your tile of choice adds $1,200-$2,800 but lets you size the shower to the exact inch and choose any drain location. For Ojus’s older bathrooms with out-of-plumb walls, the mud set corrects what acrylic cannot.
- Wall surround: Acrylic panels vs. tile vs. solid surface. Acrylic panels install fastest and cost $1,000-$2,500 for a typical three-wall surround. Tile ranges from $2,500 for basic ceramic to $6,000+ for large-format porcelain or natural stone with intricate patterns. Solid surface, such as Silestone or Caesarstone in their shower-wall applications, lands at $3,500-$7,000 and delivers seamless corners with no grout lines to maintain in hard water.
- Glass enclosure: Framed slider vs. semi-frameless vs. frameless. Framed sliders start around $900 and work in tight spaces where door swing is impossible. Semi-frameless at $1,400-$2,200 gives a cleaner sight line. Frameless runs $2,500-$4,500 depending on glass thickness and hardware finish, and it’s what most homeowners picture when they say they want a “real” shower upgrade.
- Plumbing fixtures: Builder-grade vs. name-brand pressure-balanced vs. thermostatic. Budget fixtures at $150-$300 per set work fine for a few years but use plastic cartridges that degrade in South Florida’s mineral-heavy water. Kohler and Moen brass-cartridge valves at $350-$800 per trim position last decades and have replaceable parts. Thermostatic adds $400-$900 to the valve cost but holds temperature within 1 degree, critical if your household runs multiple showers or your Ojus home has fluctuating pressure on the municipal line.
- Drain and accessibility: Standard center drain vs. linear trench vs. curbless with linear. Standard is included in base pricing. Linear trench drains add $600-$1,400 for the hardware and installation complexity. A true curbless entry, which requires lowering the subfloor or using a specialized ramped base system, adds $1,500-$3,500 but removes the trip hazard and works for aging-in-place planning.
What Tub-to-Shower Conversion Costs in Ojus, FL
| Project Component | Typical Range |
|---|---|
| Basic tub-to-shower conversion (acrylic base, surround, framed door) | $3,500-$5,500 |
| Mid-grade conversion (tiled pan, ceramic tile walls, semi-frameless glass) | $5,500-$7,800 |
| Premium conversion (mud-set pan, stone or large-format tile, frameless glass, thermostatic valve) | $7,800-$10,000 |
Five variables push any tub-to-shower conversion toward the high or low end of that spectrum:
Existing condition. A tub that has leaked for years means subfloor replacement, stud sistering, and potential mold remediation. We’ve opened walls in Ojus ranches to find the concrete block intact but the furring strips rotted through from decades of slow seepage.
Plumbing relocation. Keeping the drain and valve wall where they are saves $600-$2,000. Moving either means concrete work, new supply lines, and often a permit amendment.
Material grade. The spread between acrylic and frameless glass with stone tile can double the material portion of your budget.
Structural modifications. Widening the shower footprint into an adjacent closet or removing a non-load-bearing partition is straightforward. Anything touching a structural wall or requiring beam support triggers engineering and adds $1,500-$4,000.
Permit and inspection scope. In unincorporated Miami-Dade County, where Ojus sits, a simple fixture swap might not trigger a permit, but any wall movement, electrical work, or plumbing reconfiguration does. The county’s fee schedule and inspection queue are different from incorporated cities like Aventura, and we build that coordination into our timeline.
Our written estimates itemize labor, materials, permit fees, and a contingency line for concealed conditions. What we don’t include: homeowner selections you haven’t made yet (exact tile, glass hardware finish), HOA approval fees if your Ojus community requires architectural review, or repairs to adjacent spaces outside the wet area.
What Ojus Homes Specifically Mean for This Job
The tub-to-shower conversions we do in Ojus differ materially from the same job ten miles north in Broward County. Ojus sits inside Miami-Dade’s High-Velocity Hurricane Zone, where every structural fastener, window, door, and roofing product must carry a Miami-Dade Notice of Acceptance. That certification doesn’t apply across the county line in Hallandale Beach, and we’ve seen out-of-area contractors spec materials that are perfectly legal there but fail inspection here.
More specifically for bathroom work: any permitted renovation in Ojus triggers current HVHZ requirements for impact resistance and wind loading. A tub-to-shower conversion that stays within the existing wet-area footprint usually doesn’t touch the building envelope, but if your project includes replacing that original single-pane jalousie window with impact-rated glass, or if the bathroom shares a wall with the home’s exterior, the inspection scope expands. We account for this in our initial site visit, checking whether your bathroom window faces the prevailing wind direction and whether the wall assembly meets current Miami-Dade standards.
The housing stock itself, those 1950s-1970s concrete-block ranches along streets like NE 186th Street and in the Highland Lakes area, presents a predictable set of conditions. Cast iron tubs, galvanized drain lines, and furring strips set directly against block walls. The chronic moisture intrusion common in slab-on-grade construction here, driven by the shallow water table and porous limestone substrate, means we inspect for efflorescence and wall saturation before we quote. A shower built over damp block will fail from the back side regardless of how good the front-side waterproofing looks.
Because Ojus is unincorporated, permits pull through Miami-Dade County’s Building Department, not a city office. The plan review contacts, fee schedule, and inspection queue are county-wide systems. Contractors who work Aventura or Sunny Isles Beach but not unincorporated Miami-Dade often underpay permit fees or file under the wrong project category, adding weeks of delay. We’ve learned the filing codes that distinguish a wet-area remodel from a full bathroom gut, and we handle that coordination as part of our standard process.
Homeowners in Ojus often pair interior wet-area work with exterior envelope projects, particularly after weather events or when insurance renewals flag aging roofs. If you’re addressing multiple systems, our crew also handles Metal Roofing in Ojus and Tile Roofing in Ojus, which lets you coordinate inspections and material deliveries under one schedule rather than managing separate contractors.

Frequently Asked - Tub-to-Shower Conversion in Ojus
Most conversions finish in 5-10 business days, depending on whether we relocate plumbing and whether you choose tile or panel walls. Tile adds 2-3 days for curing and grouting. Frameless glass adds 2-3 days for templating and fabrication. We build the Miami-Dade County inspection schedule into our timeline, so you’re not waiting on us when the work is done. Call (844) 665-0162 and we’ll give you a firm schedule for your specific layout.
Yes, if we’re moving plumbing, electrical, or walls. In unincorporated Miami-Dade County, where Ojus is located, permits pull through the county Building Department, not a city office. A simple fixture swap with no wall or plumbing changes may not trigger a permit, but most conversions involve enough work that permitting is required. We handle the application, plan submission, and inspection scheduling as part of our project management. The permit fee is itemized in your estimate, not hidden.
Often, yes, and that’s the most cost-effective path. If your existing tub drain is within 12-14 inches of the wall and your valve height works for a showerhead, we can use a shower base designed for that footprint. The limitation is size: you’re locked into the tub’s original dimensions, typically 30×60 or 32×60 inches. If you want a larger shower or a curbless entry, moving the drain becomes necessary. We’ll show you both options on site and price them separately so you can decide.
The range is $3,500-$10,000. The low end gets you an acrylic pan and surround with a framed glass door, keeping your existing drain and valve locations. The high end gets you a custom mud-set pan, large-format tile or solid-surface walls, frameless glass, thermostatic valve, and any plumbing relocation or structural modification. The biggest single cost driver is whether we have to cut concrete to move the drain, which can add $1,200-$2,500 in these slab-on-grade homes. Call (844) 665-0162 for an exact quote on your bathroom - estimates are free.
We warranty our workmanship for two years on all tub-to-shower conversions. Manufacturer warranties apply to specific products: acrylic bases typically carry 10-15 years, Kohler and Moen valves carry lifetime limited warranties on brass cartridges, and glass enclosures carry 3-5 years on hardware and seals. The warranty is only as good as the installation, which is why we document our waterproofing with flood testing before tile or panels go up. We also leave you with a written maintenance guide specific to your material choices and Ojus’s water conditions.
