Tub-to-Shower Conversion in Coconut Grove: What It Costs and How Long It Takes
A tub-to-shower conversion in Coconut Grove typically runs $3,500-$10,000 and takes 5 to 10 working days from demolition to final inspection. Most homeowners in the Grove keep the existing drain location and wall footprint, which keeps the job on the shorter end of that range.

How We Handle a Tub-to-Shower Conversion From Start to Finish
We’ve done enough of these in Coconut Grove to know where the surprises hide. Here’s the actual sequence, with what happens each day and what you’ll need to decide.
Day 1: Protect and demo. We mask off hallways and cover floors, then remove the tub, surround, and any water-damaged subfloor or framing. In older Coconut Grove homes - especially the 1920s Mediterranean Revival places we see south of Tigertail Avenue - we often find single-wythe masonry walls or heart-pine framing that’s been absorbing humidity for decades. If the wall behind the tub is compromised, we’ll flag it now. You’ll decide: repair in place, or sister new framing? That choice affects both timeline and cost.
Days 2-3: Plumbing rough-in and drain verification. We pressure-test existing lines, set the new shower valve height, and rough in the drain. Keeping the drain where it is saves roughly $800-$1,500. Moving it - sometimes necessary when a homeowner wants a larger shower footprint or a linear drain against the back wall - requires breaking concrete or accessing a crawl space, which is rare in Coconut Grove’s slab-on-grade mid-century homes but common in the raised Conch cottages of the West Grove. You’ll choose your valve type now: pressure-balanced (standard), thermostatic (consistent temperature, higher cost), or a digital system if you’re running a smart-home setup.
Days 4-6: Wall prep, waterproofing, and pan installation. We install cement board or foam backer board, then apply liquid or sheet membrane to create a continuous waterproof envelope. The shower pan goes in - either a prefabricated acrylic or fiberglass base (faster, lower cost) or a mud-set pan with waterproofing fabric (custom slope, longer life, higher labor). In Coconut Grove’s salt-air environment, we use corrosion-resistant fasteners and aluminum or stainless-steel flashing at every penetration. You’ll finalize your wall material here: acrylic surround panels, large-format porcelain tile, or natural stone. Each has different waterproofing demands.
Days 7-8: Wall finishing, fixture set, and glass measurement. Tile gets set and grouted, or panels get seamed and siliconed. We install the showerhead, handheld, and any body sprays. If you’re going frameless glass, we take final measurements now - lead time is typically 10-14 days, so the glass install happens as a return trip. You’ll confirm glass thickness (3/8″ standard, 1/2″ for larger spans) and hardware finish.
Days 9-10: Final inspection, glass install, and walkthrough. We pull the plumbing permit closeout, install the glass, caulk all joints, and run a 30-minute flood test. You sign off, we haul debris. If your home is in a Coconut Grove historic district or governed by an HOA with exterior alteration rules, we’ll have already submitted any required documentation - more on that below.
The Spec Choices That Move Your Price
Every tub-to-shower conversion in Coconut Grove involves a handful of decisions that separate a $4,500 job from a $9,500 one. Here’s where the money goes.
- Shower base: Prefab acrylic or fiberglass pans ($300-$800 material) install in a few hours and carry 10-15 year warranties. Mud-set pans with topical waterproofing ($1,200-$2,500 with labor) let us build any size or shape, slope precisely for drainage, and last 30+ years if maintained. For second-story bathrooms over finished space, we typically recommend mud-set for the leak protection.
- Wall surround: Acrylic or fiberglass three-panel systems ($600-$1,400) are grout-free and low-maintenance, but the color palette is limited and they can look institutional. Large-format porcelain tile ($8-$18/sq ft installed) or quartz slab ($25-$45/sq ft) gives a custom look and holds value better in Coconut Grove’s resale market, but requires ongoing grout maintenance and higher upfront labor.
- Fixtures and valve: A quality pressure-balanced valve with a standard showerhead runs $200-$400. Thermostatic valves ($500-$900) prevent temperature swings when someone flushes a toilet elsewhere in the house - worth considering in older Grove homes with original 1/2″ supply lines and lower pressure. Multi-function shower systems with body sprays and rainheads can push fixture costs past $2,000 and may require a 3/4″ supply upgrade.
- Glass enclosure: Framed sliding doors ($600-$1,200) are functional and cost-effective. Frameless hinged or fixed panels ($1,500-$3,500) use thicker glass and precise hardware, but they open up sight lines in smaller bathrooms - common in the 1950s-70s ranch homes on the east side of Coconut Grove near Peacock Park.
- Structural or plumbing moves: Keeping everything where it is saves the most money. Widening the shower footprint, moving the drain, or converting a tub under a window to a curbless walk-in (popular for aging-in-place plans) adds $1,500-$4,000 depending on what’s underneath and how much reframing the floor structure needs.
What Tub-to-Shower Conversion Costs in Coconut Grove, FL
For a typical tub-to-shower conversion in Coconut Grove, expect to invest between $3,500 and $10,000. Here’s what pushes a job toward the low or high end of that range.
| Cost Factor | Low-End Impact | High-End Impact |
|---|---|---|
| Shower base type | Prefab acrylic pan | Custom mud-set with linear drain |
| Wall finish | Acrylic surround panels | Large-format tile or stone slab |

A written estimate from us includes demolition, disposal, all plumbing rough and finish, wall prep and waterproofing, the shower base, wall finish installation, fixture set, and permit pulling. What it typically does not include: the glass enclosure (we measure and coordinate, but glass is a separate vendor invoice), any electrical work beyond a simple exhaust fan swap, or repairs to adjacent rooms if hidden damage extends past the wet area. We’ll flag these possibilities during the on-site visit so you’re not surprised.

What Coconut Grove’s Old Housing Stock Means for This Job
Coconut Grove isn’t like the rest of Miami-Dade, and that matters when you’re cutting open a bathroom wall.
The neighborhood contains some of the county’s oldest residential structures - wood-frame Caribbean “Conch” vernacular homes in the West Grove built by Bahamian settlers in the 1890s-1910s. When we’re converting a tub in one of these, we’re working with heart-pine framing that’s been absorbing Biscayne Bay’s salt-laden humidity for over a century. The dense tropical canopy of protected banyans and mahogany trees traps moisture against exterior walls, and we’ve seen fungal decay in bathroom adjacent framing that simply doesn’t occur a few miles inland. That means our demolition phase includes probing for soft spots we wouldn’t expect in a 1990s build.
Then there’s the compliance stack. Miami-Dade’s post-Hurricane Andrew high-velocity wind-load codes are among the strictest in the nation, and if your home is in a historic district or subject to West Grove Historic Preservation Board oversight, any exterior alteration - including bathroom window replacement or vent modifications - requires separate approval. We’ve had jobs where the plumbing permit was ready in 48 hours but the historic review added three weeks. We build that timeline into our schedule, and we handle the submission so you’re not navigating county and city portals yourself.
For bayfront properties, CCCL (Coastal Construction Control Line) setback restrictions can constrain where we stage materials or place a debris bin, though they rarely affect interior bathroom work directly. The bigger factor is the salt air itself: we specify corrosion-resistant fasteners and aluminum flashing at every penetration, because standard steel will rust through in this environment faster than you’d think.
We cover Coconut Grove from the West Grove to the waterfront estates along Biscayne Bay, and we’ve worked on every era of housing stock this neighborhood offers.

Frequently Asked - Tub-to-Shower Conversion in Coconut Grove
Most conversions take 5 to 10 working days, with frameless glass installation as a separate return trip. Historic Preservation Board review, if required for exterior window or vent changes, can add 2 to 4 weeks before work starts. Call (844) 665-0162 and we’ll check whether your property triggers that layer.
Yes - Miami-Dade County requires a plumbing permit for any drain or valve modification, and a building permit if you’re altering walls or structural elements. We pull both as part of our standard process. If your home is in a historic district, a separate preservation review may also be required.
Often, yes. Keeping the existing drain location and valve wall is the most cost-effective path and works for roughly 70% of the bathrooms we see in Coconut Grove. You’ll get a standard 36″ x 48″ or 36″ x 60″ shower footprint. If you want a larger walk-in or a curbless entry, moving the drain is usually necessary - we’ll show you both options during the estimate.
A prefab acrylic base with surround panels typically lands in the $3,500-$5,500 range. A mud-set pan with full tile walls and frameless glass usually runs $7,500-$10,000. The custom route adds durability and resale value, especially in Coconut Grove’s market, but both are valid depending on your timeline and budget.
We warranty our workmanship for one year, and the materials we install carry their own manufacturer coverage - typically 10-15 years on prefab bases, lifetime on many valves, and 30+ years on mud-set pans when properly maintained. We document every warranty and leave you with the paperwork. For an exact quote on your bathroom, call (844) 665-0162 - estimates are free and include a written scope.
