What a Tub-to-Shower Conversion in Island Walk Actually Costs and How Long It Takes
A tub-to-shower conversion in Island Walk replaces your existing bathtub with a walk-in shower and typically runs between $3,500 and $10,000 depending on whether you keep the original footprint or move plumbing. Most jobs in this neighborhood take our crew five to seven working days, start to finish. Call (844) 638-7249 for a line-item written estimate on yours - they’re free and there’s no commitment.
Island Walk’s DiVosta-built homes from the late 1990s and early 2000s hit a predictable inflection point: the original fiberglass tub-shower combos start looking tired, the tub surround develops hairline cracks, and a tub you never use is eating floor space you could put to work. Replacing it with a shower makes sense. That one-piece original unit comes out in a morning. What takes the week is everything afterward - waterproofing, pan slope, tile or solid-surface walls, glass enclosure, and the final trim.
How We Convert a Tub to a Shower - the Actual Sequence
You’re not walking into a showroom and picking a shower off the shelf. Here’s what happens from the day we pull the permit to the day you use the shower.
Stage 1: Demo and wall assessment (Day 1). The old tub, surround, and valve come out. Because Island Walk homes use DiVosta’s solid poured concrete walls, there is no stud cavity to simply open up and reroute plumbing through - every penetration requires core drilling. We assess the subfloor and the concrete wall behind the surround for any water damage, which we see regularly in this neighborhood where original builder-grade waterproofing has been failing for two decades. If there’s rot or mold, this is when you’ll know and we’ll give you a change-order price before the next step.
Stage 2: Rough plumbing and shower pan (Day 2-3). The drain gets relocated from tub height and position to a centered shower drain, the valve gets upgraded to a pressure-balanced or thermostatic unit, and we pour a properly sloped mortar pan. In Island Walk’s concrete-slab-on-grade homes, moving a drain even a few inches means saw-cutting the slab - which is standard for this neighborhood but surprises homeowners who’ve never opened a concrete floor before. We rough in any additional fixtures now: bench blocking, niche framing, grab-bar backing.
Stage 3: Waterproofing and wall prep (Day 3-4). This is the step that separates a shower that lasts ten years from one that causes a mold claim. We apply a full liquid or sheet membrane system across the pan, curb, and walls up to the showerhead height - minimum 72 inches. The concrete walls get a bonding primer suited for masonry, and we set the substrate for whatever wall finish you chose back in the design phase. Collier County requires a rough-in inspection at this point, so we schedule that and don’t cover anything until the inspector signs off.
Stage 4: Tile or solid surface, plus fixtures (Day 4-6). Wall material goes up, grout cures, the shower floor gets its finish surface, and the valve trim, showerhead, and any body sprays or hand showers get installed. If you chose a frameless glass enclosure, we take final measurements now - glass is always cut to the finished opening, never from plans. In a DiVosta home with poured concrete walls, hanging a heavy glass door requires sleeve anchors rated for solid concrete, not standard drywall anchors.
Stage 5: Glass install and final trim (Day 6-7). The enclosure goes in, we caulk every seam and transition, and do a full flood test of the pan. The job isn’t done until you’ve walked the shower with our lead installer and every single thing that bothers you has been addressed. That’s not a courtesy. That’s the point of hiring a crew that shows up in uniform and answers the phone at midnight.
The Options You’ll Choose Between
Every tub-to-shower conversion in Island Walk runs through the same four decisions. Here’s what actually matters when you’re looking at your estimate.
- Keeping the original footprint vs. expanding. A straight swap - tub out, shower in, same 60-inch alcove - sits at the low end of the price range. Expanding the shower deeper into the bathroom or stealing closet space pushes the job toward $8,000-$10,000 because you’re moving plumbing and building new walls. In a DiVosta concrete home, moving plumbing across a slab floor adds real labor dollars.
- Shower base material: acrylic pan vs. tile floor. A pre-formed acrylic or solid-surface pan installs in a day, costs less, and never needs resealing. A tile shower floor with a mortar bed feels better underfoot and can be sloped to exact dimensions, but adds two to three days and roughly $1,200-$2,000 to the job. For Island Walk homeowners planning to stay in the house for a decade, we recommend tile and a Quikrete mortar bed - you’ll never think about it again.
- Wall finish: acrylic/laminate vs. tile vs. solid slab. Acrylic panels are the most affordable and the easiest to clean. Porcelain or ceramic tile gives you unlimited design flexibility but grout maintenance is real. Solid-surface slabs - think cultured marble or quartz - eliminate grout lines entirely but cost roughly 25-40% more than standard tile. If someone in the household has mobility concerns, we often steer toward slab walls with integrated grab bars we block during rough-in.
- Enclosure: framed, semi-frameless, or frameless glass. A framed sliding door is functional and inexpensive. A frameless glass panel with a swing door looks like something out of a Naples design magazine and adds $800-$1,500 to the glass portion of the job. Worth it if the shower is the bathroom’s focal point; skip it if this is a guest bath behind a pocket door.
What a Tub-to-Shower Conversion Costs in Island Walk, FL
You should budget between $3,500 and $10,000 in this neighborhood. A straightforward conversion - tub out, acrylic shower pan and surround in, standard valve and showerhead, framed glass door - will land around $3,800-$5,500. A higher-end job with a tiled floor, full porcelain tile walls, a frameless enclosure, a bench, and a rain showerhead runs $7,500-$10,000.
What pushes the number toward the high end:
- Size. Expanding beyond the 60-inch tub alcove means framing, concrete slab work, and drywall.
- Existing condition. If the original DiVosta tub surround has been leaking - and we see this in roughly one out of every five Island Walk bathrooms we open - subfloor or concrete remediation adds cost on Day 1.
- Plumbing scope. Moving the drain location, upgrading to a thermostatic valve with volume control, or adding body sprays all increase labor and fixture cost.
- Material grade. The jump from $3/sq ft subway tile to $12/sq ft handmade tile changes the materials line by nearly $1,000 on a standard alcove.
Every estimate we write is line-itemed and fixed. The number on the estimate is the number you pay - we do not write change orders unless you ask for something different mid-job or we open a wall and find something no contractor could have predicted. The estimate includes demo, debris removal, plumbing rough-in and finish, shower pan, waterproofing, wall and floor finish, glass enclosure, and a final walkthrough. It does not include the permit fee - that’s a direct pass-through from Collier County - or any tile or fixture upgrades you make after you sign.
For a larger project that goes beyond the bathroom, many Island Walk homeowners roll their shower conversion into a full Bathroom Remodeling in Island Walk - the per-job cost drops when we’re already on site for a multi-week remodel. We’ll walk you through the numbers either way.
What Island Walk Homes Specifically Do to This Job
If you live in Island Walk, your house was almost certainly built by DiVosta Homes between roughly 1996 and 2006. That matters for a tub-to-shower conversion in ways that a generic bathroom contractor from Fort Myers won’t anticipate.
The wall behind your tub surround is solid poured concrete. There is no stud cavity. There is no hollow block. When the old valve comes out and you want the new shower valve raised or relocated, the plumber isn’t fishing pipe through an open bay - they’re core-drilling through reinforced concrete. We budget for that on every Island Walk estimate because skipping it gets a contractor halfway through Day 2 before they realize they need a diamond-tipped coring bit they don’t own. The plumbing rough-in takes half a day longer here than it does in a stick-framed Naples home, and we’ve never met an Island Walk homeowner who wanted to pay a crew to stand around while someone rents equipment.
Permitting runs through Collier County, and yes - you need a permit for a tub-to-shower conversion if plumbing rough-in is involved. Our team pulls it, schedules the inspection, and makes sure the waterproofing gets signed off before any tile goes up. No shortcuts. This is part of the standard process we’ve built for Island Walk, where every home we open has the same DiVosta bones and the same 20-to-30-year-old builder-grade components reaching end of life.
If your conversion is part of a larger exterior renovation - some homeowners pair a bathroom refresh with roofing work - our bathroom remodeling crew and roofing team coordinate schedules so you’re not living through back-to-back construction. We’ve done projects where a Metal Roofing in Island Walk upgrade happened on the same timeline, and others where Tile Roofing in Island Walk repairs ran concurrently. It’s not the typical pairing, but when it lines up, the efficiency is real.

Frequently Asked - Tub-to-Shower Conversion in Island Walk
Five to seven working days, from demo to final glass install. In a straightforward footprint-preserving conversion with an acrylic pan and surround, we’ve finished in four days. Tile work, frameless glass, or plumbing relocation pushes the job into the six-to-seven-day range. The Collier County rough-in inspection adds a day of scheduling between waterproofing and finish surfaces.
Yes. Collier County requires a plumbing permit when drain or supply lines are altered, which they are in virtually every tub-to-shower conversion. We pull the permit, schedule the rough-in and final inspections, and the permit fee appears as a direct pass-through line on your estimate - we don’t mark it up.
Sometimes, if the tub drain is already near the center of the alcove and the valve height works for a shower. Most DiVosta tubs we see in Island Walk have the drain at the foot end, which means we’re moving it toward the center and cutting the concrete slab. We tell you during the on-site estimate whether yours can stay put or needs to shift - there is no guessing.
Not unless we find something no visual inspection could have revealed - like water damage behind the original surround or a concrete slab issue under the tub - and you approve a change order before we proceed. We write fixed, line-item estimates. If the number changes, you’ll know why and you’ll sign off before anyone picks up a tool. The 730-Day Done Right Promise means we have zero incentive to cut corners that create callbacks later.
Every conversion is covered by our 730-Day Done Right Promise. If something wasn’t installed correctly, we fix it - for two full years. Shower pans are flood-tested before glass goes in, every valve is pressure-tested, and the waterproofing gets inspected by the county. The warranty is long because the work is done right the first time.
