Tub-to-Shower Conversion in Miami Shores: What It Costs and How Long It Takes
A tub-to-shower conversion in Miami Shores typically runs $3,500-$10,000 and takes 5-10 business days from demolition to final inspection, though the village’s Architectural Review Board adds 4-6 weeks to the front end for ARB approval before permits issue. Most homeowners in the 33153 area call us at (844) 665-0162 after realizing their 1940s-era tub and surround have become daily inconveniences. We’ll walk you through what drives the timeline, what you’ll need to decide, and how Miami Shores’ unique approval process affects your project.
How We Handle Tub-to-Shower Conversion Start to Finish
We’ve done enough of these in Miami Shores to know where the delays hide. Here’s the actual sequence, with the decisions you’ll need to make at each stage.
Stage 1: Site measure and ARB package prep (Week 1-2)
We visit your home, photograph the existing bathroom, and document the exterior fenestration if your bathroom window faces the street. The Miami Shores ARB requires elevation drawings showing that any exterior changes, including window modifications for ventilation, maintain the Mediterranean Revival character. We prepare this package and submit before the monthly deadline. Missing it means waiting another 28-31 days. You’ll decide: keep the existing window size, or resize for better exhaust and natural light?
Stage 2: ARB review and permit pull (Week 3-6)
The board meets, typically approves interior-only work with no exterior visibility changes, and we pull the building permit. If your home sits on a corner lot with side-street exposure, the review may take longer. You’ll need to approve any material samples the ARB requests, usually tile or fixture finish boards.
Stage 3: Demolition and rough plumbing (Days 1-2)
We remove the tub, surround, and valve assembly. In Miami Shores homes built 1935-1955, we frequently find original cast iron drain lines with threaded brass fittings or early copper with leaded joints. These require careful extraction; hammering blindly cracks the hollow clay tile walls common in this era. We’ll know by noon on day one whether your drain line needs replacement or can be adapted. You’ll decide: standard 2-inch drain or upgrade to a linear drain for a curbless entry?
Stage 4: Waterproofing, tile, and fixture set (Days 3-5)
We install cement board or foam wall panels, apply liquid or sheet membrane waterproofing, then set tile and grout. Floor slope to the drain gets verified with a laser level, critical in these flat-topography homes where slab settlement isn’t uncommon. You’ll decide: porcelain tile, large-format ceramic, or solid surface panels? Each has different grout maintenance and slip-resistance profiles.
Stage 5: Glass, final trim, and inspection (Days 6-8)
We install the shower door or curtain rod, set trim plates, caulk, and call for final plumbing inspection. Miami-Dade inspectors verify anti-scald valve function and drain flow rate. We clean, photograph, and walk you through maintenance. You’ll decide: framed, semi-frameless, or frameless glass? The ARB has no jurisdiction here, but your home’s original window grids may influence your choice for visual consistency.
The Material and Configuration Choices You’ll Face
Every tub-to-shower conversion involves trade-offs between upfront cost, daily usability, and long-term maintenance. Here’s what we most often discuss with Miami Shores homeowners:
- Shower base: acrylic insert vs. tiled mud pan. Acrylic runs $800-$1,800 installed, installs in hours, and has a 10-15 year lifespan before surface wear shows. A custom mud pan with waterproofing membrane and tile adds $1,500-$3,200 but lets you shape the exact size and slope, lasts 25+ years, and matches period bathrooms better. For ARB-sensitive homes where authenticity matters, we usually recommend mud pan.
- Wall surround: fiberglass panels vs. cement board and tile vs. solid surface. Fiberglass is budget-friendly at $600-$1,400 but looks institutional and cracks on impact. Cement board with porcelain tile ($2,000-$5,000) offers infinite design flexibility and holds value in historic-character homes. Solid surface like Corian or Swanstone ($1,800-$4,000) has seamless corners, no grout to clean, and installs faster, though color matching to existing trim can be tricky.
- Plumbing fixtures: standard valve vs. thermostatic vs. digital. A pressure-balance valve ($180-$350) prevents scalding when someone flushes a toilet. Thermostatic ($400-$800) holds exact temperature regardless of pressure fluctuation. Digital systems ($1,200-$2,500) offer presets and remote activation; overkill for most conversions, but popular in homes where we’re already upgrading electrical panels.
- Glass enclosure: framed, semi-frameless, or frameless. Framed ($400-$900) is functional and watertight. Semi-frameless ($700-$1,400) reduces metal sightlines. Frameless ($1,100-$2,800) uses thicker glass and minimal hardware; in salt-air Miami Shores, we specify 316 marine-grade stainless or aluminum with anodized finish to prevent the corrosion we see on cheaper hardware within 3-4 years.
- Niche, bench, and accessibility features. A tiled niche adds $300-$600. A fold-down bench runs $250-$500. Curbless entry with trench drain adds $1,200-$2,400 but eliminates the trip hazard and suits aging-in-place plans. Given Miami Shores’ older homeowner demographic, we field this question often.

Why Miami Shores Homes Make This Job Different
The tub-to-shower conversions we do in Miami Shores bear little resemblance to the same job in North Miami or unincorporated Miami-Dade. The village’s 1930s-1950s housing stock, built mostly with hollow clay tile and stucco over early concrete block, creates structural constraints that newer construction simply doesn’t have. We’ve removed tubs where the surrounding tile was set directly onto the clay tile with a half-inch of mortar bed, adding 200+ pounds to the demo load and requiring careful handling to avoid cracking the exterior stucco.
The ARB process is the other variable. Miami Shores Village requires board approval before any building permit issues, a two-layer system that doesn’t exist one mile south. The board meets monthly, and their submission deadline is absolute. Contractors unfamiliar with this rhythm routinely lose four to six weeks waiting for the next meeting. We calendar every Miami Shores project around the ARB schedule; it’s often the longest lead item, not material delivery.
Salt air from Biscayne Bay, less than a mile east, also changes our material specs. Standard zinc-plated shower door hardware shows surface rust within two years here. We specify Miami-Dade NOA-approved fasteners and 316 stainless or anodized aluminum for any metal components. The same corrosion risk applies if your bathroom window faces east or south, where we may recommend impact-rated vinyl or aluminum-clad replacements that meet both the ARB’s aesthetic requirements and the county’s wind-load codes.
Finally, the original plumbing. Cast iron drains and galvanized supply lines are common in the 33153 ZIP. A tub-to-shower conversion is often the first time a homeowner has opened that wall since 2014. We plan for the possibility of drain replacement, not just adaptation, and we communicate that before demolition starts.

Frequently Asked - Tub-to-Shower Conversion in Miami Shores
The construction phase takes 5-10 business days, but the total project timeline from signed contract to final inspection is typically 8-12 weeks due to Miami Shores’ Architectural Review Board approval process. Call (844) 665-0162 and we’ll check the next ARB deadline so you know your real start date.
Yes, and you’ll need ARB approval first. The village requires board sign-off on any construction before the building department will issue a permit, even for interior-only work if your bathroom has a street-facing window. We handle both applications as part of our project management.
Often yes, if your existing tub drain is centered and your valve wall is in a workable position. We keep the drain location in about 60% of Miami Shores conversions, which holds the price toward the lower end of the range. If your 1940s tub has an end drain or the valve is on the wrong wall for your preferred layout, relocation adds $800-$3,500 depending on slab access and pipe material.
Tub replacement runs $3,000-$8,500; tub-to-shower conversion runs $3,500-$10,000. The overlap is wide because a basic acrylic tub swap can be cheaper than a tiled walk-in shower, but a high-end soaking tub with surround often exceeds a mid-range conversion. Most Miami Shores homeowners who call us have already decided on the shower; they’re asking about feasibility and timeline, not trying to minimize spend.
We warranty our workmanship for one year, and the materials carry their own manufacturer warranties, typically 5-10 years for shower bases, 10 years for tile installations when installed to TCNA standards, and lifetime for many valve cartridges. We register warranties in your name and leave you the documentation. For questions about coverage on a specific product, call (844) 665-0162 before we finalize your selections.
