A Tub-to-Shower Conversion in Naples Manor Runs $3,500-$10,000 and Usually Takes About a Week
Tub-to-shower conversion in Naples Manor means we pull out the old tub, reconfigure the plumbing footprint, waterproof and tile the enclosure, and finish with the glass, trim, and fixtures you picked - and most projects land between $5,500 and $8,500, finished in five to seven working days. The swap makes sense when a bathtub collects more dust than use, or when climbing over the side has stopped feeling safe.

What you get at the end is a walk-in shower built to modern Florida code on a pan that won’t leak, with grab-bar blocking in the walls whether you install bars today or five years from now. We do this the way we do every job at Groundwork Construction Co.: upfront pricing, a crew in uniform, and the whole thing backed by our 730-Day Done Right Promise - if it’s not done right, we make it right.
How We Convert a Tub to a Shower - The Real Sequence
We lay out the timeline before the first hammer swings so you know what happens, which days noise and dust are a factor, and when you make decisions that affect the final cost. Here is how the full job breaks across a typical week in Naples Manor.
Stage 1: Demo, Floor-Check, and Plumbing Assessment (Day 1)
The old tub comes out, the tile and backer board get stripped to the studs, and we open enough of the floor to inspect the trap, drain line, and subfloor. In Naples Manor’s older block homes, we often find a cast-iron tub set in a mortar bed above a slab-on-grade - no crawlspace to work from, so the plumber cuts and re-routes inside the existing footprint unless you choose to relocate the drain. This is the day we confirm whether the original cast-iron p-trap needs replacement and how much slab cutting is required. You walk us through the space so we know exactly where you want the valve, showerhead, niche, and bench before we start rough-in.
Stage 2: Rough Plumbing, Valve, and Drain Work (Day 2)
The plumber moves or replaces the drain line to center the new shower pan, sets the mixing valve at the height you chose, and caps the tub overflow because a shower doesn’t need one. If you want a second showerhead or a handheld on a slide bar, now is when the extra drop-ear elbow and blocking go in. Once the pressure test passes - and in unincorporated Collier County, the inspector looks at this before we cover anything - we move to waterproofing. This stage runs one to two days depending on how much slab cutting was required.
Stage 3: Pan, Curb, and Waterproofing (Day 3-4)
We pour or set the pre-sloped pan, build the curb, and install cement board or a foam backer system on the walls, taped and sealed at every seam. Then a liquid-applied membrane or sheet membrane goes on - floor, walls, curb, and up at least six inches past the showerhead height - so the entire wet zone is a single waterproof envelope. We reinforce corner changes with fabric and seal the drain flange with a clamping ring and membrane. The waterproofing cures overnight. A second Collier County inspection happens here if the first raised any flags; otherwise the county bundles the rough and waterproofing into one visit.
Stage 4: Tile, Niche, Bench, and Fixtures (Day 4-6)
Tile goes in: floor first, then walls, niche, and bench face. We use epoxy grout in the wet zone - it doesn’t need sealing, doesn’t stain, and holds up to Naples Manor’s humidity without turning into a mold colony. Once the tile sets and the grout cures, we mount the showerhead, arm, trim kit, handheld, and any grab bars. If we pre-blocked for a folding teak seat or a corner shelf, that hardware screws in solid. The glass enclosure gets measured at this stage if we haven’t already templated it, and fabrication happens offsite - usually two to three extra days after tile is grouted.
Stage 5: Glass, Final Trim, and Your Walkthrough (Day 7)
The glass enclosure goes in: custom-cut tempered panels with clean silicone joints and minimal metal framing - or semi-frameless if the budget leads there. We check every silicone bead, test the valve and diverter, run the shower for five minutes to confirm no leaks at the pan or drain, and walk you through the space to make sure the niche height feels right and the handheld reaches comfortably. That walkthrough is when we log the job as complete and your 730-Day Done Right Promise clock starts running. If anything isn’t right, you say so then and we fix it - before we leave the driveway.
The Options You’ll Choose Between
Most of the cost spread in a Naples Manor tub-to-shower conversion comes from the materials and configuration decisions you make before we order anything. Here are the big ones, with the honest trade-offs.
- Acrylic or fiberglass pan vs. tile floor. A pre-formed pan is the lower-cost route and has no grout lines to maintain, but limits you to stock sizes and a handful of neutral colors. A tiled shower floor with a mortar bed gives you unlimited size and slope flexibility, plus a custom look that matches the wall tile exactly. Tile costs more in labor and material, and the grout lines need an occasional wipe-down to stay bright.
- Standard ceramic wall tile vs. large-format porcelain. Ceramic tile in the $3-$6/sq ft range - four- or six-inch squares or subway - keeps the material cost down; installation is straightforward. Large-format porcelain panels or 12×24-inch tiles reduce grout lines and look cleaner, but the material price steps up and labor rises because the substrate has to be dead flat. Both hold up to Southwest Florida humidity perfectly well when the waterproofing behind them is done right.
- Semi-frameless glass vs. fully frameless. Semi-frameless enclosures use a thin aluminum header and bottom track to stabilize stock glass panels - they cost less, install in one trip, and keep water inside the shower. Fully frameless uses thicker ⅜-inch or ½-inch tempered glass with minimal clips and hinges; it opens up the room visually and is easier to squeegee clean, but adds $900-$1,800 to the enclosure cost in this market.
- Single showerhead vs. rain head with handheld. A fixed showerhead on a single-function valve is the simplest and least expensive setup. Adding a rain head and a handheld on a diverter or a thermostatic valve means more rough-in work, a bigger valve, and an extra drop for the handheld - the plumbing materials alone can add $400-$900. If you live with anyone who might sit while showering, the handheld is worth it every time.
- Recessed niche vs. corner shelf. A tiled niche built between stud bays gives you clean, flush storage; we block and waterproof it the same way as the walls. A corner shelf or two costs less and can be added anywhere without reframing, but protrudes into the shower space and collects soap-scum at the edges. We can do either, or both, depending on stud layout and what’s behind the wall.
What Tub-to-Shower Conversion Costs in Naples Manor, FL
A tub-to-shower conversion in Naples Manor typically falls between $3,500 and $10,000. The midrange - where most of our jobs land - sits around $5,500 to $8,500. That covers demo and disposal of the old tub and surround, plumbing reconfiguration to center the drain and set the valve, new acrylic or tiled pan with curb, cement board and full waterproofing, wall tile in a standard format, a single-function valve and fixed showerhead, and either a semi-frameless glass enclosure or a curtain rod accounted in the quote until you choose.
What pushes a job toward the higher end:
- Slab cutting to relocate the drain. Many Naples Manor homes sit on slab-on-grade; if the existing tub drain sits at the far end and you want a centered shower drain, the plumber saws into concrete and runs new ABS - that alone can add $900-$1,400.
- Upgraded tile and glass. Large-format porcelain, full-height tile to the ceiling, mosaic accents, and frameless ⅜-inch glass enclosure with minimal hardware push the finish-material line item past what a standard subway-and-stock-glass job costs.
- Valve and fixture upgrades. A thermostatic valve, a diverter for a second showerhead, a rain head, or a handheld on a slide bar - each adds to the plumbing materials and the labor to block, mount, and trim them.
- Structural surprises behind the wall. In a pre-1992 concrete-block home, we occasionally find corroded copper risers, termite damage in the bottom plate, or un-reinforced chase walls that need sistering before waterproofing. We show you photos and give you a fixed price for the repair before we do the work - no “we found this and already fixed it, so your bill went up” phone calls.
- Permit fees and county inspection scheduling. Collier County charges a permit fee based on job valuation, plus surcharges for plan review if the scope triggers it. Most tub-to-shower conversions fall under a straightforward plumbing and building alteration permit, but if we discover that the original tub was installed without a permit or the electrical bonding needs bringing up to code, the scope and the county fees increase modestly.

What Naples Manor Homes Specifically Do to This Job
Naples Manor’s housing stock - mostly 1950s-to-1970s concrete-block homes on slab-on-grade - shapes a tub-to-shower conversion in ways that don’t show up in a newer subdivision. The original bathrooms were framed with a cast-iron tub set directly on the slab in a wet bed; the drain is often a threaded cast-iron p-trap buried in concrete, and the plumbing chases cut through block walls that carry no extra room for a 2-inch shower drain unless we open the slab. Because Naples Manor sits in unincorporated Collier County, the permitting and inspection process runs through the county building department rather than the City of Naples - different fee schedule, different inspector territory, and a different set of eyes on whether the waterproofing meets Florida Building Code Chapter 27 before tile covers it.
The other major variable is the water table. Many Naples Manor lots sit in AE or X-500 flood zones with groundwater that rises to within a foot of grade during the rainy season. That doesn’t affect the shower pan itself - we’re above the slab - but it means any sub-slab drain relocation has to be planned around a dry week, and we triple-check the slab penetration seal so groundwater vapor doesn’t wick into the wall cavity. When we pull a Collier County permit, the inspector often asks about floodplain compliance and elevation even on interior renovations, particularly if the home’s assessed value makes the job flirt with the ‘substantial improvement’ threshold. Homeowners who pair a tub-to-shower conversion with a larger Bathroom Remodeling in Naples Manor package should understand how that threshold works before contracting - we walk you through it during the estimate.
We have worked on enough bathrooms in Naples Manor to plan around these realities from day one. Our team stages materials under cover so an afternoon thunderstorm doesn’t ruin a pallet of backer board, and we sequence inspections to keep the county turnaround from stalling the job. These are not hypotheticals here - they’re standard operating procedure for any crew that actually works the neighborhood.

Frequently Asked - Tub-to-Shower Conversion in Naples Manor
Most jobs finish in five to seven working days. Demo and plumbing rough-in eat up the first two days, waterproofing and tile fill days three through six, and the glass goes in on day seven once fabrication is done. If the shower glass needs a custom template, that adds two to three days between tile completion and final install - but you have a functioning (curtained) shower while you wait. Collier County inspections add a day or two total depending on the inspector’s queue that week. Call (844) 638-7249 and we’ll map out the exact timeline for your bathroom.
Yes. Because the job moves a drain and modifies the plumbing system, Collier County requires a plumbing and building alteration permit. We pull the permit, handle the inspections, and keep the job moving so the process doesn’t stall your schedule. An unpermitted shower is a disclosure headache when you sell the house, and insurance adjusters notice missing permits after a water-damage claim.
Sometimes. If the existing tub drain sits reasonably close to center and the trap arm is in good shape, we can keep the drain location and avoid slab cutting entirely - that is the best-case scenario and trims $900 or more from the plumbing cost. But many Naples Manor tubs were installed with the drain at the far end, and a shower with a drain in the corner feels wrong underfoot. We’ll show you both options during the estimate and give you a fixed price for each.
A tub-to-shower conversion in Naples Manor generally runs $3,500 to $10,000, with most jobs falling between $5,500 and $8,500. The spread depends on drain relocation, tile selection, glass style, and whether the job stays a straightforward swap or uncovers plumbing or framing that need repair. The estimate we give you is a fixed, line-by-line written quote - no change orders unless you ask for a change. Reach us at (844) 638-7249 for your free on-site estimate.
