Tub-to-Shower Conversion in Olympia Heights: Scope, Timeline, and Cost
A tub-to-shower conversion in Olympia Heights removes your existing bathtub and replaces it with a dedicated shower enclosure, typically finished in 5 to 7 working days. Most Olympia Heights homeowners pay between $3,500 and $10,000 depending on whether plumbing stays in place and what materials you select.

How We Handle the Full Conversion Process
We’ve done enough tub-to-shower conversions in 33165 to know where the surprises hide. Here’s the actual sequence, what you’re deciding at each point, and how long each stage takes.
Day 1: Protect and Demo
We cover floors and doorways, shut off water, and remove the tub, surround, and any water-damaged subfloor or framing. In Olympia Heights homes from the 1950s through 1970s, we often find galvanized supply lines or cast-iron drain stacks that need replacement before new work begins. You’ll decide now whether to keep the existing footprint or expand the shower footprint into adjacent space. This stage takes one day.
Days 2-3: Rough Plumbing and Structural Prep
If you’re keeping the drain and valve locations, we verify slope and pressure. If you’re moving anything, this is when we open walls and run new copper or PEX supplies and PVC drainage. For homeowners who want a zero-threshold or curbless entry, we lower the subfloor or install a prefabricated shower pan with an integrated linear drain. You’ll choose your shower valve type now, thermostatic or pressure-balance, because rough-in depth varies. Two days, sometimes three if we hit the Miami Rock Ridge and need specialized cutting equipment for drainage trenches.
Day 4: Wall Prep and Waterproofing
We install cement board or foam shower wall panels, then apply liquid or sheet membrane waterproofing to Miami-Dade’s flood-prone standards. You’ll confirm your wall tile or solid-surface panel selection by this point, since panel thickness affects framing depth. One day.
Days 5-6: Tile or Panel Installation and Fixture Set
Wall surfaces go in, followed by floor tile or a prefabricated pan. We set the shower valve trim, head, and any handheld or body-spray components. If you selected a frameless glass enclosure, we template now for custom fabrication. You’ll do a walkthrough to confirm grout color and fixture finish. Two days.
Day 7: Glass, Final Plumbing, and County Inspection
We install the enclosure, seal all joints, run pressure tests, and call for Miami-Dade County’s final plumbing inspection. Because Olympia Heights is unincorporated, there’s no city inspector, only county enforcement, and they will verify that any window or exterior door modified during the conversion carries HVHZ-approved impact ratings if it opens to the outside. One day, though inspection scheduling can add a buffer depending on county backlog.
The Options You’ll Actually Choose Between
- Shower pan type: Prefabricated acrylic or fiberglass pans run $400-$900 and install fast, but the color and texture choices are limited and they can flex or crack over time. Custom tile pans with a PVC or CPE membrane start around $1,200 in labor and materials but give you exact size control and a higher-end look. For Olympia Heights homes with subtle floor settlement on the Rock Ridge, we often recommend the tiled pan because it tolerates minor movement better than a rigid prefab unit.
- Wall surround material: Acrylic wall systems go up in a day, cost less, and have seamless corners that resist mold. Tile, natural stone, or engineered quartz panels (Cambria and Silestone both make shower-appropriate surfaces) cost more and take longer but give you design flexibility and higher resale value. In the humid subtropical climate here, we specify epoxy grout or large-format tiles with minimal joints to reduce mildew risk.
- Plumbing configuration: Keeping your existing drain and valve location saves $800-$1,500. Moving the drain across the floor means cutting into that oolitic limestone subfloor, which adds labor and sometimes requires a concrete saw rental. We map this out in the first visit so you’re not surprised.
- Enclosure style: A framed sliding door in standard sizes starts around $600. Frameless glass, which most of our Olympia Heights clients prefer for the clean look, runs $1,800-$3,500 depending on glass thickness and hardware finish. If your bathroom has an exterior window that we’re replacing as part of the project, that window must be impact-rated per Miami-Dade’s HVHZ product approval list, a requirement that out-of-county crews frequently miss.
- Fixture grade: Builder-grade chrome valve and showerhead sets start around $150. Mid-grade brushed nickel or matte black sets from recognized manufacturers run $400-$700 and carry better cartridge warranties. We source through our standard supply relationships so you’re not locked into a single brand.

A written estimate from us includes demolition, disposal, rough and finish plumbing, waterproofing, wall and floor finishes, fixture installation, and the glass enclosure. It does not include permit fees (paid directly to Miami-Dade County), any repair of hidden water damage we discover after demo, or bathroom flooring that extends beyond the shower footprint. If your 1960s CBS home has unpermitted electrical or plumbing that surfaces during inspection, we’ll quote that separately before proceeding.
Many homeowners pair a tub-to-shower conversion with a broader update. If you’re considering a full Bathroom Remodeling in Olympia Heights, we coordinate the shower work with vanity replacement, flooring, and lighting under one timeline and one point of contact.
What Olympia Heights Homes Specifically Do to This Job
Olympia Heights presents a particular permitting reality because the community is unincorporated. Every tub-to-shower conversion permit routes through Miami-Dade County’s building department, not a local city hall, and county inspectors apply the same High-Velocity Hurricane Zone standards used on coastal properties. That means if your bathroom renovation touches an exterior window or door, the replacement product must carry a Miami-Dade Notice of Acceptance (NOA), a product-approval step unique to this county that stalls projects when out-of-area contractors spec standard catalog items.
The housing stock itself shapes our approach. Most homes here are single-story concrete block and stucco construction from the 1950s through 1970s, built during rapid post-war suburban expansion and modified informally by successive residents. We regularly find bathrooms with galvanized supply lines, cast-iron drains, or unpermitted electrical extensions that have to be brought current before new work can pass inspection. The Miami Rock Ridge limestone beneath Olympia Heights also means any drainage relocation requires slower, equipment-intensive cutting compared to sandy-soil neighborhoods to the north.
Because so many of these homes lack the hurricane straps, impact-rated openings, and reinforced tie beams required after Hurricane Andrew, a bathroom remodel often becomes the moment when homeowners address broader envelope upgrades. Our Metal Roofing in Olympia Heights and Tile Roofing in Olympia Heights crews frequently coordinate with our bathroom team when a homeowner is tackling multiple systems at once. From driveway to roofline, one contractor handles every phase.
We’ve worked on streets from Southwest 24th to Coral Way and throughout the 33165 ZIP, and the pattern holds: older CBS construction, informal additions, and county-level inspection rigor that rewards contractors who know the local product-approval list.

Frequently Asked - Tub-to-Shower Conversion in Olympia Heights
The build itself takes 5 to 7 working days, though Miami-Dade County inspection scheduling can add 2 to 5 calendar days depending on their backlog. Call (844) 665-0162 and we’ll check current county turnaround times when we quote your project.
Yes. Because Olympia Heights is unincorporated, all permits run through Miami-Dade County, and any plumbing modification requires a permit and inspection. If your project includes replacing an exterior window, that product must also meet HVHZ impact standards with county-approved documentation.
Often yes, if your existing drain location and valve height work for a standard shower configuration. Keeping everything in place saves roughly $800-$1,500 and eliminates the need to cut into the Rock Ridge subfloor. We’ll verify slope and pressure during our first visit to confirm.
The lowest-cost path uses a prefabricated acrylic pan and surround, keeps existing plumbing in place, and selects a framed glass door or curtain rod rather than frameless glass. That combination typically lands near the $3,500 end of our range. You choose the brand and grade, we handle the build.
We warranty our workmanship on waterproofing, plumbing connections, and installation. Fixture and material warranties come from the manufacturers you select, and we pass those documents directly to you. For specific coverage terms on your product choices, ask during your estimate walkthrough.
