Walk-In Showers & Shower Remodeling in Three Lakes - What’s Involved and What It Costs
Walk-in showers & shower remodeling in Three Lakes typically runs $4,500-$12,000 for a full installation or gut renovation, with most projects wrapping in 10-14 business days from permit approval. You’ll need a Miami-Dade building permit for any plumbing relocation, wall modification, or drain alteration, and the HVHZ jurisdiction here means every fixture and glass enclosure must carry a current Notice of Acceptance. Call (844) 665-0162 and we’ll walk you through what’s required for your specific layout.
How we approach walk-in showers & shower remodeling - the real process
We’ve refined this into five clear stages so you know what’s happening and when you need to make decisions. No surprises, no open-ended timelines.
Stage 1: Site measure and scope lock (Day 1)
We show up with a laser measure, moisture meter, and camera. You’re deciding three things here: keep the existing footprint or expand it, keep the drain location or move it, and whether you’re removing a tub, an old shower pan, or both. We photograph every wall cavity we can access, check for prior water damage in the 33186 area’s CBS construction, and flag any galvanized plumbing that needs updating. This visit takes 90 minutes. You get a written estimate within 48 hours.
Stage 2: Material selection and permit prep (Days 2-7)
Now you pick. Shower base: curbed or curbless? Curb-less needs a linear drain and precise slope engineering, which adds $800-$1,800 but eliminates the trip hazard. Wall surround: large-format porcelain, fiberglass surround, or tiled wet wall? Fixtures: pressure-balanced or thermostatic valve? We spec everything to Miami-Dade HVHZ product-approval standards, which means your glass enclosure, if any, must carry a valid NOA number. We submit the permit application with the product cut sheets attached. Lead time right now is 5-7 business days for residential plumbing permits in this part of unincorporated Miami-Dade.
Stage 3: Demo and rough-in (Days 8-10)
Crew arrives. Old shower comes out, walls open to the studs. We inspect for termite damage, old cast-iron drains, and the subfloor condition. In Three Lakes homes built during the 1980s surge, we regularly find original copper drains with pinhole corrosion where the water table has kept slab areas damp. If we’re moving the drain, this is when we core the slab - and in this area, that means hitting Miami oolite limestone anywhere from 4 to 12 inches down. It’s hard on bits but stable once cut. Rough plumbing and any electrical for lighting or heated floors goes in. Inspector visits for rough-in sign-off.
Stage 4: Waterproofing and finish (Days 11-16)
Hot-mopped pan or bonded membrane? We use liquid-applied waterproofing on walls with fabric reinforcement at seams - faster than traditional methods, and it passes Miami-Dade’s moisture-barrier scrutiny. Tile or surround goes up. Grout, cure time, then fixture set. If you’ve chosen frameless glass, we template once the walls are finished and order from our HVHZ-approved fabricator. That adds 7-10 days to total timeline but arrives after everything else is done.
Stage 5: Final inspection and walkthrough (Day 17-19)
Plumbing inspector confirms no leaks, proper venting, and correct fixture placement. We run every fixture for 20 minutes, check drainage speed, and review care instructions. You sign off. The permit closes.
The choices that actually change your shower
- Shower base: standard acrylic pan vs. tiled mud pan vs. solid-surface. Acrylic runs $400-$900 installed, lasts 15-20 years, and comes in standard sizes. Tiled mud pans start around $1,200 with waterproofing but let you customize any dimension and match wall tile exactly. Solid-surface like Swanstone or Corian hits $1,800-$3,000, feels warmer underfoot, and has no grout lines to maintain. For Three Lakes homeowners planning to age in place, the zero-threshold solid-surface base is worth the premium.
- Wall surround: fiberglass surround vs. tile vs. large-format porcelain slabs. Fiberglass three-piece surrounds are $600-$1,200, one-day install, 10-year life. Tile gives you design control but demands maintenance - regrouting every 5-7 years in this hard-water region. Large-format porcelain or sintered stone slabs (think 5×10 foot panels) run $2,500-$5,500 installed, have nearly invisible seams, and clean like glass. We source these through our partnerships with Silestone and Caesarstone for clients who want that seamless look.
- Fixtures: builder-grade vs. thermostatic vs. digital. A basic pressure-balanced valve and trim set costs $150-$400. Thermostatic valves maintain temperature within 1 degree when someone flushes a toilet elsewhere in the house - $400-$900 for the valve alone, worth it in homes with original 3/4-inch supply lines that struggle with pressure. Digital shower systems (Kohler DTV, Moen U) run $1,200-$3,500 and need a dedicated electrical rough-in. We wire these during Stage 3 if you choose one.
- Glass enclosure: framed vs. semi-frameless vs. frameless. Framed sliding doors are $600-$1,200, pass HVHZ easily, but collect grime in the metal tracks. Semi-frameless hits $1,000-$1,800 and looks cleaner. True frameless with 3/8-inch tempered glass and minimal hardware runs $1,800-$3,500 and must carry a Miami-Dade NOA for wind-load compliance - we verify this before ordering, not after.
- Niche, bench, and storage. Tiled corner bench: $400-$800. Floating solid-surface bench: $900-$1,400. Recessed shampoo niche with waterproofed shell: $250-$500 each. These get decided during Stage 2 because they affect framing and waterproofing layout.

What Three Lakes specifically means for your shower project
Three Lakes sits in Miami-Dade’s High-Velocity Hurricane Zone, and that changes material specs and permitting in ways Broward County contractors sometimes miss. Every glass enclosure, every window, every exterior door referenced in your permit package needs a current Miami-Dade Notice of Acceptance number. We’ve seen out-of-county crews spec beautiful frameless systems that sat in warehouse limbo for three weeks while they scrambled for HVHZ-compliant alternatives. We verify NOA status before anything gets ordered.
The housing stock here - mostly CBS construction from the 1970s through early 1990s - means we’re often working with original galvanized drains and supply lines that have reached end of life. The porous Miami oolite bedrock keeps slab work stable but can surprise crews expecting deeper trenching. And that high water table? It means any subfloor damage we find during demo needs immediate attention; moisture wicks fast in this soil. Homeowners in the townhome clusters near the retention lakes particularly need us to check for prior slab leaks that went unreported.
If you’re considering Bathroom Remodeling in Three Lakes as part of a full renovation, we coordinate the shower scope with vanity relocation, tile flooring, and any window upgrades to minimize repeated inspections. Many homeowners tackling a full Bathroom Remodeling project with us also address exterior work - Roof Replacement & Installation in Three Lakes or Metal Roofing in Three Lakes - to consolidate permitting and inspection schedules under one accountable team. We cover Three Lakes and the surrounding Kendall corridor from our Fort Lauderdale base, and we know the Miami-Dade permitting portal’s current queue times firsthand.

Frequently asked - Walk-In Showers & Shower Remodeling in Three Lakes
Most projects finish in 10-14 business days after permit approval, assuming no hidden damage and standard material lead times. Frameless glass enclosures add 7-10 days because they get templated after walls are finished. If you’re on a tight timeline, we can spec in-stock framed glass and keep the total under two weeks. Call (844) 665-0162 and we’ll map a schedule to your move-in or guest arrival date.
Yes, if you’re moving plumbing, modifying walls, or changing the drain location. Miami-Dade requires a plumbing permit for any fixture relocation and a building permit if structural walls are affected. Simple fixture swaps in the same location sometimes don’t need permitting, but we verify that with the unincorporated Miami-Dade building department before starting - never guess on code compliance. Our estimates include permit submission and inspection scheduling.
Usually, and it’s the single biggest factor in keeping your project toward the $4,500-$6,500 range. Keeping the drain and valve wall where they are eliminates slab cutting, concrete repair, and additional rough-in inspections. We only recommend moving plumbing when the existing layout is genuinely dysfunctional - like a tub-shoe drain that can’t accommodate a proper shower slope, or a valve positioned where a frameless door needs to hinge.
A walk-in shower is built from scratch in a dedicated shower space or full bathroom gut, with custom waterproofing and your choice of base size. A tub-to-shower conversion repurposes the existing tub footprint, which constrains dimensions but costs less - typically $3,500-$10,000 versus $4,500-$12,000 - because the drain location and surrounding walls are largely preset. We offer tub-to-shower conversion as a separate service if that’s your specific scenario.
We warranty our waterproofing and workmanship for five years, and every fixture we install carries its manufacturer’s warranty - typically lifetime on Kohler and Moen valves, 10-15 years on finishes, and varying terms on glass hardware. The waterproofing warranty is what matters most in Three Lakes’ humidity; if we did the prep, we stand behind it. Manufacturer warranties require registration, which we handle during final walkthrough.
