Tub-to-Shower Conversion in Lake Forest: What It Costs and How Long It Takes
A tub-to-shower conversion in Lake Forest, FL typically runs $3,500-$10,000 and takes 3-5 working days from demolition to final inspection. The job removes your existing bathtub and surround, then installs a waterproof shower base, wall system, fixtures, and glass enclosure in the same footprint. Most Lake Forest homeowners call us at (844) 665-0162 when they’re tired of climbing over a tub they never use, or when the original fiberglass unit from the 1970s or 1980s has cracked beyond repair.
How We Handle a Tub-to-Shower Conversion from Start to Finish
We’ve done enough of these in Lake Forest’s older CBS homes to know where the surprises hide. Here’s what actually happens, and what you’ll need to decide at each stage.
Stage 1: In-Home Measurement and Plumbing Assessment (Day 0, 60-90 minutes)
We visit your home, photograph the existing tub and surround, and trace the drain and supply lines. The big question at this stage: are your pipes copper or galvanized? Galvanized supply lines in pre-1992 Lake Forest homes often need replacement to meet current Miami-Dade code, which adds $800-$2,400 to the project. We also check whether your drain is centered (standard tub) or offset (some corner units), since this determines which shower bases will fit without relocating plumbing. You’ll decide at this visit whether you want to keep the same layout or move the drain, which triggers permit drawings and a longer timeline.
Stage 2: Demolition and Substrate Inspection (Day 1, 4-6 hours)
We remove the tub, surround, and any tile down to the studs. In Lake Forest’s concrete-block homes, we often find the original tub was set in a mortar bed on a plywood subfloor over the slab, not a pre-formed receptor. This means we may need to pour a new sloped shower pan with waterproof membrane, which adds a day but prevents the failures we see when contractors skip this step. You’ll see photos of what we found, and we’ll confirm whether the wall framing is plumb enough for a direct-to-stud surround or needs shimming for tile.
Stage 3: Rough Plumbing and Electrical (Day 1-2, 6-8 hours)
If we’re keeping the drain location, this stage moves fast. If we’re moving it, we cut into the slab, which in Lake Forest means hitting that oolitic limestone substrate within 12-18 inches. Jackhammering through Miami rock adds half a day and $400-$900 in labor. We also rough in any new plumbing for a handheld wand, body sprays, or a thermostatic valve if you upgraded. Electrical work at this stage is usually limited to a new GFCI-protected outlet or relocated exhaust fan switch. You’ll have already chosen your valve trim finish by now, since we need to set the rough-in depth precisely.
Stage 4: Wall System and Base Installation (Days 2-3, 8-10 hours)
This is where your material choice shows. Acrylic or fiberglass surround panels go up in a few hours and are ready for fixtures same day. Tile takes longer: cement board, waterproofing membrane (we use liquid-applied or sheet membrane depending on your spec), tile layout, setting, grouting, and sealing. A full tile surround adds 1-2 days but gives you the custom look many Lake Forest homeowners want when this project is part of a full Bathroom Remodeling in Lake Forest. You’ll do a midpoint walkthrough to confirm grout color and tile layout before we set anything in mortar.
Stage 5: Fixtures, Glass, and Final Inspection (Days 4-5, 4-6 hours)
We install your showerhead, valve trim, any accessories, and the glass enclosure. Frameless glass requires precise measurements and ships 10-14 days after templating, so this sometimes happens as a follow-up visit. In Miami-Dade, tub-to-shower conversions require a plumbing inspection if any drain or supply line was altered, and a final building inspection if walls were opened. We schedule these; you don’t need to be present, though you can be. The permit closes once the inspector signs off, usually within 48 hours of our final walkthrough.
The Choices That Shape Your Shower: Materials and Configurations
Every tub-to-shower conversion forces a series of either/or decisions. Here’s how we guide Lake Forest homeowners through them.
- Shower base: fiberglass/acrylic pan versus poured sloped pan with tile. The pre-formed pan ($400-$800 material) installs fast, has a 10-15 year warranty, and works well for standard 60″ x 30″ or 60″ x 32″ openings. A poured pan with waterproof membrane ($1,200-$2,800) is the only right choice for custom sizes or when you want tile underfoot. It adds a day and costs more, but we’ve replaced too many leaking fiberglass pans in Lake Forest’s older homes to recommend them for anything but budget-focused rentals.
- Wall surround: direct-to-stud acrylic panels versus cement board and tile. Acrylic systems like Kohler’s Choreograph or similar modular lines run $1,500-$3,500 installed, resist mold, and clean easily. Tile walls range from $2,500 for basic ceramic to $6,000+ for natural stone or large-format porcelain. The trade-off is maintenance: acrylic never needs regrouting; tile grout in South Florida’s humidity needs sealing every 12-18 months or it stains.
- Valve and trim: pressure-balance versus thermostatic. Pressure-balance valves (standard, $150-$400) prevent scalding when someone flushes a toilet. Thermostatic valves ($400-$900) hold temperature within 1-2 degrees regardless of pressure changes, which matters in Lake Forest’s older homes where galvanized pipes create pressure inconsistencies. Most of our clients choose thermostatic for master baths, pressure-balance for guest baths.
- Glass enclosure: framed sliding door versus frameless hinged. Framed sliders ($600-$1,400) seal better and fit tighter spaces. Frameless systems ($1,800-$4,000) use thicker glass, feel more open, and show off tile work. In Miami-Dade’s HVHZ, frameless glass must carry a Miami-Dade NOA, which limits brand options but ensures wind-load compliance. We source from manufacturers with approved products, never generic imports.
- Fixtures: builder-grade versus name-brand. Moen and Kohler valves and trim carry lifetime warranties, have replacement parts available in 10 years, and their finishes match across product lines. Off-brand fixtures save $200-$500 upfront but fail faster and can’t be repaired. Our Bathroom Remodeling crew stocks common Kohler and Moen finishes for faster completion.

Our written estimate includes demolition, disposal, all materials, labor, permit fees for Miami-Dade, and inspections. It does not include repairs to unexpected rot or termite damage behind walls (uncommon in CBS block homes but possible in wood-framed additions), asbestos abatement if your home predates 1980 and we encounter suspect materials, or cosmetic touch-ups to adjacent walls outside the shower envelope. We flag these possibilities during the initial assessment so you’re not surprised.
Homeowners often pair a bathroom update with exterior work while our crew is on site. If you’re also considering Metal Roofing in Lake Forest or Tile Roofing in Lake Forest, we can coordinate inspections and scheduling through one point of contact.
Why Lake Forest Homes Make This Job Different
Lake Forest sits in Miami-Dade County’s High Velocity Hurricane Zone, the most stringent wind-load construction jurisdiction in the United States. Every product we install, from glass enclosures to exhaust fans, must carry a Miami-Dade Notice of Acceptance (NOA). Contractors from Broward or Palm Beach counties routinely bring non-NOA materials that fail inspection, delaying projects by weeks. We’ve seen it happen when homeowners hire out-of-area crews who don’t understand the difference.
The housing stock here is predominantly concrete-block CBS construction from the 1960s through 1980s, much of it built before Hurricane Andrew forced the 1992 code overhaul. Those original bathrooms often have galvanized supply lines, cast-iron drains, and tub surrounds set in mortar beds that have degraded over 40-60 years. The concrete block itself is durable, but the infrastructure inside it is past service life. We also work around the realities of South Florida’s rainy season, scheduling any slab cutting or exterior vent modifications for morning windows before afternoon thunderstorms saturate the site.
The flat, low-lying terrain of northeastern Miami-Dade means water tables are high and drainage is slow. When we do need to cut slab for drain relocation, we hit that oolitic limestone substrate quickly. Jackhammering through Miami rock is standard practice for local contractors, but it adds time and cost that surprises builders unfamiliar with the geology. We build this into our estimates upfront, not as a change order later.

Frequently Asked - Tub-to-Shower Conversion in Lake Forest
Most conversions take 3-5 working days if we’re keeping the existing drain location and using an acrylic or fiberglass surround. Tile walls, drain relocation, or slab work in Lake Forest’s limestone substrate extends this to 6-8 days. Miami-Dade inspections add 1-2 days depending on inspector availability. Call (844) 665-0162 and we’ll give you a firm timeline based on your specific layout.
Yes, if any plumbing or drainage is altered. Miami-Dade Building Code requires a plumbing permit for drain or supply line changes, and a building permit if walls are opened to the studs. We pull permits, schedule inspections, and ensure all materials carry the required NOA approval. Homeowners who skip permitting risk failed resale inspections and insurance issues after water damage.
Often yes, if your existing drain is centered in a standard 60″ x 30″ or 60″ x 32″ opening. Many pre-1990s Lake Forest tubs have offset drains or corner placements that limit base options, but we carry shower receptors in multiple drain configurations. During our initial measurement, we’ll confirm whether your plumbing can stay put or if relocation is necessary for the layout you want.
The lowest-cost approach is a direct replacement: keep the drain location, install a fiberglass or acrylic shower base and surround, use a pressure-balance valve with standard fixtures, and choose a framed sliding glass door. This typically lands near $3,500-$4,500. We don’t recommend cutting corners on waterproofing or skipping the permit, since both create expensive problems later. Call (844) 665-0162 for an exact quote - estimates are free.
We warranty our workmanship for one year on all installations. The materials carry their own manufacturer warranties: acrylic bases typically 10-15 years, tile waterproofing systems 10 years, Kohler and Moen fixtures lifetime, glass enclosures 3-5 years depending on brand. We register all warranties in your name and leave you with documentation. Any issue in year one, we return and fix it.
