Tub-to-Shower Conversion in North Miami Beach: What It Costs and How Long It Takes
A tub-to-shower conversion in North Miami Beach typically runs $3,500-$10,000 and takes 5-10 business days from demo to final inspection, depending on whether your existing plumbing stays put and whether your building needs Miami-Dade NOA-compliant materials. Most 1960s-1980s condos and single-family homes in the 33160 corridor can keep their drain and valve locations, which keeps the timeline and budget at the lower end.

How We Handle Tub-to-Shower Conversion from First Visit to Final Walkthrough
We’ve refined this into five clear stages so you know what’s happening, what you’re deciding, and when the job will be done.
Stage 1: Site measure and scope lock (Day 1, 90 minutes on site)
We show up, photograph the existing tub and surround, confirm drain location and pipe condition, and test water pressure. You’ll decide right then: keep the existing plumbing footprint or relocate it. Keeping it saves roughly $800-$2,000 and 1-2 days. We also note whether your building requires Miami-Dade NOA-compliant fixtures, which is standard for every condo tower along the Intracoastal in North Miami Beach.
Stage 2: Material selection and permit pull (Days 2-5, homeowner does this from home)
We send you a spec sheet with your shower pan options (acrylic, fiberglass, or tile-over-foam), wall surround materials, fixture grades, and glass enclosure types. You’ll pick finishes and confirm the pan size, typically 32×60 inches or 36×48 inches for standard tub alcoves. We submit the permit application to Miami-Dade County during this window. If you’re in a condo with an active milestone inspection timeline, we coordinate our scope letter with your association’s engineer so our work doesn’t conflict with scheduled concrete or waterproofing repairs.
Stage 3: Demo and rough prep (Days 6-7, 1-2 crew members)
We remove the tub, surround, and any damaged substrate, then expose the drain and valve lines. If your home is one of the 1950s-1970s CBS single-family houses in the inland pockets of North Miami Beach, we often find cast-iron drains that need transitioning to PVC. We handle that in this stage. If we hit corroded copper or galvanized supply lines, we’ll flag it before proceeding.
Stage 4: Pan install, waterproofing, and surround (Days 8-10)
The shower pan goes in first, leveled and strapped to code. We apply liquid or sheet membrane waterproofing, then install your chosen wall system. Tile jobs take longer than acrylic surrounds, typically adding 2-3 days for set and grout cure time. We pressure-test the valve and drain before closing walls.
Stage 5: Fixture set, glass, and inspection (Days 11-12)
Final fixture installation, glass enclosure hang, caulk, and cleanup. Miami-Dade inspects for pan strapping, waterproofing continuity, and valve accessibility. We pass the inspection, close the permit, and walk the job with you. If you’re wrapping this into a full Bathroom Remodeling in North Miami Beach project, we sequence this phase to align with vanity and flooring crews so you’re not living in a construction zone longer than necessary.
The Material and Configuration Choices You’ll Actually Make
Every tub-to-shower conversion forces a few decisions that affect price, durability, and daily use. Here’s where homeowners in North Miami Beach typically land:
- Shower pan: acrylic vs. tile-ready foam vs. custom mud bed. Acrylic pans ($400-$900 installed) are fastest and lowest maintenance, but the colors are limited and the “plastic” feel bothers some buyers. Tile-ready foam pans ($600-$1,400) let you set any tile you want on the floor, which matters if you’re matching existing bathroom tile in a 1970s CBS home. Custom mud beds ($1,200-$2,500) slope perfectly and last decades, but they add two days and require a skilled hand. We see most condo owners in North Miami Beach choose acrylic for speed and most single-family homeowners choose tile-ready for aesthetic continuity.
- Wall surround: fiberglass surround vs. tile vs. solid surface panels. Fiberglass surrounds ($800-$1,800) install in hours and never need grout maintenance, which appeals to owners of rental units and seasonal condos. Tile ($1,500-$4,000 depending on material and pattern) gives you design control but demands regrouting every few years in South Florida’s humidity. Solid surface panels like Corian or Swanstone ($2,000-$3,500) split the difference, seamless and grout-free with a higher-end look.
- Fixtures: builder grade vs. pressure-balance vs. thermostatic valve. Builder-grade single-handle valves ($150-$300) work fine for basic use. Pressure-balance valves ($300-$600) prevent scalding when someone flushes a toilet, worth it in homes with original 1960s plumbing that can’t handle modern flow rates simultaneously. Thermostatic valves ($600-$1,200) hold exact temperature, a luxury choice we see in full-gut Bathroom Remodeling projects where the owner is upgrading everything at once.
- Glass enclosure: framed sliding vs. semi-frameless vs. frameless. Framed sliders ($600-$1,200) are practical for tight spaces and tight budgets. Semi-frameless ($1,000-$1,800) drops the top rail for a cleaner look. Frameless ($1,500-$3,000) uses thicker glass and minimal hardware, the standard choice when the bathroom is being opened up as part of a larger renovation. In North Miami Beach’s HVHZ, all glass must be impact-rated or protected by impact-rated shutters, which affects enclosure spec and cost.
- Grab bars, niches, and bench seating. These add $200-$800 each but transform usability. We recommend deciding on blocking for grab bars during Stage 2 even if you don’t install them immediately, it’s nearly free foresight that saves wall demolition later.
What Tub-to-Shower Conversion Costs in North Miami Beach, FL
Tub-to-shower conversion in North Miami Beach ranges from $3,500 to $10,000. Here’s what pushes a job toward either end:
| Cost Factor | Low-End Scenario | High-End Scenario |
|---|---|---|
| Plumbing footprint | Keep existing drain and valve location | Relocate drain, add second valve, upgrade supply lines |
| Shower pan and walls | Acrylic pan, fiberglass surround | Custom mud bed, floor-to-ceiling tile, solid surface panels |
| Fixture grade | Builder-grade single-handle | Thermostatic valve, handheld, rain head, body sprays |
| Glass enclosure | Framed sliding door | Frameless with heavy glass, custom cut |
| Structural surprises | Clean demo, sound substrate | Rotten subfloor, corroded cast iron, concrete spalling repair |
| Permit and inspection scope | Single-family home, standard county permit | Condo with engineer coordination, NOA documentation, HOA approval |
A written estimate from us includes demo, disposal, pan and surround installation, waterproofing, basic fixture set, glass enclosure, permit fees, and final inspection. It does not include tile (if you choose that route, we price it separately per square foot), plumbing line relocation beyond 24 inches, subfloor repair, or any mold remediation discovered during demo. We flag likely extras during the site visit so you’re not surprised.
Many homeowners tackling exterior work simultaneously ask about our Metal Roofing in North Miami Beach or Tile Roofing in North Miami Beach crews, we can coordinate scopes so you’re not juggling multiple contractors across different project phases.
What North Miami Beach Homes Specifically Do to This Job
The housing stock in North Miami Beach’s 33160 ZIP creates a split personality for tub-to-shower conversion work. Inland, we find 1950s-1970s CBS single-family homes with original cast-iron tubs, galvanized supply lines, and bathrooms that were never designed for walk-in showers. The drain is almost always centered, the valve is typically 48 inches high on a side wall, and the alcove is 60 inches wide with a window over the tub that has to stay for ventilation. Converting these means deciding whether to keep that window inside the new shower zone, which requires a vinyl or tileable window replacement, or closing it and adding an exhaust fan.
Along the Intracoastal and near the Atlantic, the story is different. Those 1960s-1980s poured-concrete condo towers have bathrooms with cast-iron tubs set on concrete slabs, no basement access, and drain lines embedded in the slab. Moving a drain here means core-drilling concrete, which adds $1,500-$3,500 and structural engineer sign-off. More critically, these buildings are now under Florida’s post-Surfside Milestone Inspection Law, with 25-year recertification deadlines for coastal structures. We’ve had jobs delayed because the association’s engineer flagged our bathroom wall as part of a scheduled concrete spall repair two months out. We now ask condo owners upfront for their building’s inspection status and engineer contact, it’s saved us and our clients from mid-project stops.
The salt air and humidity here also mean we spec stainless or brass drain assemblies, never standard steel, and we use mold-resistant cement board behind tile instead of paper-faced drywall. Miami-Dade’s HVHZ status means every fixture and glass panel needs that NOA compliance documentation, which we handle but which adds a day to material procurement. If your building’s milestone inspection is pending, our North Miami Beach crew knows how to write a scope letter that satisfies both your association and the county.

Frequently Asked - Tub-to-Shower Conversion in North Miami Beach
Most conversions finish in 5-10 business days. Keeping your existing plumbing footprint and choosing an acrylic pan with a fiberglass surround gets you to the lower end. Tile, plumbing relocation, or condo engineer coordination pushes toward 10-12 days. Call (844) 665-0162 and we’ll time-line your specific layout.
Yes, Miami-Dade County requires a plumbing permit for any tub removal and shower installation, plus an electrical permit if you’re adding or relocating lighting, fans, or heated floors. Condo buildings may also require HOA architectural approval. We pull all permits and coordinate HOA submissions as part of our scope.
In most North Miami Beach homes, yes. If your tub drain is centered and your valve is on the wall opposite the showerhead, we can install a shower pan and surround directly in the existing footprint. The exceptions are when the drain is too close to the wall for code-compliant pan slope, or when the existing valve height won’t clear a standard showerhead, both fixable but adding cost.
A basic conversion with acrylic pan, fiberglass surround, builder-grade fixtures, and framed glass starts around $3,500. A full upgrade with tile-ready pan, floor-to-ceiling ceramic or porcelain tile, thermostatic valve, frameless glass, and built-in niche typically lands at $7,500-$10,000. The biggest variable is whether we keep or relocate plumbing, that single decision often swings the price by $1,500 or more.
We warranty our installation workmanship, including waterproofing integrity, pan strapping, and fixture function. Manufacturer warranties cover the specific products you choose, acrylic pans typically carry 10-30 years, tile 5 years on installation, and fixtures 5 years to lifetime depending on brand. We register all manufacturer warranties for you and leave documentation in your project binder.
