What a Tub-to-Shower Conversion Involves in Alva, and What It Costs
A tub-to-shower conversion removes your existing bathtub and reconfigures the plumbing, waterproofing, and finishes to create a dedicated walk-in shower in the same footprint. In Alva, this job typically takes 5 to 8 working days from demolition to final inspection. Realistic pricing for a tub-to-shower conversion in this area sits between $3,500 and $10,000, with most of the homes we work on landing in the $5,500 to $8,000 range once material selections are made and any subfloor surprises are addressed.

How a Tub-to-Shower Conversion Progresses on a Typical Alva Job
Stage 1: Tear-Out and Exposure (Day 1)
We remove the tub, the surrounding wall finishes, and the valve trim to expose what’s behind the walls and under the tub. This is the moment we learn the real condition of the subfloor, the framing, and the drain location. In Alva, especially on post-Ian rebuilds where moisture intrusion was severe, this exposure stage occasionally reveals subfloor rot that requires a partial replacement before we proceed. We walk you through exactly what we found before we order the first new material.
Stage 2: Rough-In and Waterproofing (Days 2 and 3)
Your existing tub drain (1½ inch) gets upsized to a 2-inch shower drain to handle the faster runoff a shower produces. The shower valve is relocated from tub height to shower height, and we run new supply lines if the old galvanized piping is corroded, which we encounter regularly in Alva homes built before the 1990s. The shower pan base is sloped and a full waterproofing system, either a sheet membrane or a liquid-applied barrier, is installed across the shower floor and up the walls before a single tile or wall panel goes in. If the county inspector needs to sign off on the rough plumbing, we coordinate that visit during this phase.
Stage 3: Wall and Curb Assembly (Days 3 and 4)
This is where the shower takes its shape. We frame any niche openings you’ve chosen for shampoo ledges, build the curb if the design calls for one, and hang the backer board. For low-barrier or curbless conversions, which we’re doing more of in Alva for aging-in-place clients, the shower floor gets recessed into the joist bay to keep the entry threshold nearly flush with the bathroom floor. Your material selections drive the timeline here: solid-surface wall panels install in hours, while large-format tile with intricate patterns adds a day.
Stage 4: Tile, Grout, and Trim-Out (Days 4 through 7)
Tile work begins at the floor and moves up the walls. We set the drain grate, tile the pan and the walls, install any accent bands or niche trim, and let the thin-set cure fully before grouting. Once the grout is sealed, our plumber returns to set the shower valve trim kit, the shower head, and any hand-shower or body-spray components you’ve selected. The glass enclosure is measured on-site after tile is complete because the dimensions shift by small fractions during construction; the glass typically arrives and is installed on day 7 or 8.
Stage 5: Final Walkthrough and Sign-Off (Day 8)
We run the shower, check every seam and connection, verify the drain flow rate, and clean the job site. The Lee County final inspection, if a permit was pulled, happens once we’ve confirmed everything is watertight and code-compliant. You get a written close-out showing exactly what was done, what products were used, and the start date of your 730-Day Done Right Promise. From that day forward, if anything isn’t performing the way it should, we make it right.
The Choices You’ll Make for an Alva Tub-to-Shower Conversion
Every tub-to-shower conversion forces a handful of real product decisions. Here are the ones that affect your price and your daily use of the shower:
- Shower pan vs. tiled floor. A prefabricated solid-surface shower pan installs in a few hours, never needs resealing, and costs less. A tiled shower floor with a mortar-bed pan is fully custom, offers unlimited size and drain placement, and costs more, but it gives you a seamless look. For Alva homes on a slab foundation, the tiled pan often makes more sense because the floor is already structurally rigid.
- Wall material: acrylic surround, solid-surface panels, or tile. A direct-to-stud acrylic surround is the most budget-friendly and fastest to install. Solid-surface panels like Onyx Collection or Transolid give you a grout-free, easy-to-clean surface in a mid-range price bracket. Tile, whether ceramic, porcelain, or natural stone, is the top of the budget but gives you the most design freedom. We carry a curated set of brands so you pick from proven materials, not catalogs filled with anything that’s in stock.
- Curb vs. curbless entry. A standard raised curb contains water and keeps the job simple. A curbless shower with a linear drain is more expensive because it requires recessing the floor structure, but it’s the right call for homeowners planning to age in place or anyone who wants a step-free entry. Alva’s slab-on-grade homes can accommodate a curbless design by cutting and re-pouring a section of the slab; pier-and-beam homes need the joist bay dropped.
- Shower door style: framed, semi-frameless, or frameless. Framed doors are the economy option. Semi-frameless gives you a cleaner look at a middle price point. Frameless heavy-glass enclosures with minimal hardware are the premium choice and the most popular among Alva homeowners doing a conversion as part of a larger Bathroom Remodeling in Alva.
- Valve and fixture grade. A pressure-balance valve is standard and code-compliant. A thermostatic valve adds precise temperature control and is worth the upgrade if your household has young children or older adults who are sensitive to temperature swings. Fixture finishes, chrome holds up in hard-water conditions better than brushed nickel or matte black, a relevant factor on Alva’s well-water properties that don’t run a whole-house softener.
What a Tub-to-Shower Conversion Costs in Alva, FL
A tub-to-shower conversion in Alva runs $3,500 to $10,000, with most jobs falling between $5,500 and $8,000. That range covers everything from a straightforward acrylic surround replacement to a fully tiled, curbless shower with a frameless glass enclosure and upgraded fixtures. Here are the variables that push a project toward the high or low end of that range:
- Subfloor condition. If the tub has been leaking slowly for years and the subfloor is compromised, replacing a section of OSB or plywood adds $300 to $800 and is non-negotiable once the rot is exposed. Alva homes that sat with standing water after Ian are more prone to hidden subfloor damage than homes in dryer inland communities.
- Plumbing relocation. Keeping the drain and supply lines in their existing locations keeps the job affordable. Moving the drain across the slab or through joists to change the shower orientation adds $800 to $2,200 depending on access and whether concrete cutting is required.
- Waterproofing scope. Code requires a waterproof pan and a minimum-height wall barrier. We waterproof the entire wet area floor to ceiling regardless of code minimums because it’s the right way to build, but adding a full liquid-applied membrane system over cement board adds material cost that a basic fiberglass surround avoids.
- Enclosure glass. A simple framed sliding door might add $400. A custom frameless enclosure with ⅜-inch tempered glass and inline panel clips can run $1,200 to $2,000 depending on the opening width and whether it’s a single door or a door-plus-panel configuration.
- Permit fees. Lee County permit costs for a tub-to-shower conversion are typically $120 to $350 depending on the valuation of the work and whether the project triggers a plan review. We pull the permit on your behalf and the fee is a line item on your estimate, not a markup buried in the total.
Every estimate we write is a line-item quote, not a bottom-line number with vague scope. You see the demolition, the plumbing, the waterproofing, the materials you picked, and the labor to install them all broken out. Our bid is a fixed price, and short of a subfloor discovery that changes the scope, the number on your estimate is the number you pay. Our bathroom remodeling crew has been building showers across Southwest Florida long enough to know that nobody wants a surprise change order halfway through the job.
How Alva Homes Change This Specific Job
Tub-to-shower conversions in Alva carry a few realities that a coastal Lee County contractor rarely faces. The biggest one is water. Alva sits in the Caloosahatchee River floodplain, and Hurricane Ian’s 2022 inland flooding, not Gulf storm surge, damaged or destroyed a large share of local homes. That means the subfloor and wall cavities we open during demolition often tell a story. On pre-Ian homes that were repaired rather than rebuilt, we encounter moisture-damaged framing and elevated humidity readings that were sealed behind drywall during the initial remediation. On post-Ian rebuilds, the homes are elevated 2 to 4 feet above the original slab grade on stem-wall or pier foundations, which changes the plumbing access underneath the bathroom floor and occasionally requires us to reroute the drain line through the new elevated structure rather than tying into an existing below-grade slab drain.
The housing stock itself varies enormously. We work on older ranch-style site-built homes on large lots in the north River Road corridor, manufactured homes on agricultural parcels where the bathroom subfloor is often particle board that disintegrates at the first sign of moisture, and equestrian estate properties with oversized bathrooms that were never designed for a modern walk-in shower footprint. Older homes built before Lee County’s current plumbing code often have 1½-inch tub drains that must be upsized to 2 inches, and we regularly replace sections of corroded galvanized supply piping in homes that haven’t had a plumbing update in 40 years. The permit process goes through Lee County, and we handle the application, the scheduling, and the on-site inspection coordination so you don’t spend a morning waiting for an inspector who may or may not show up on time. Some Alva homeowners doing a tub-to-shower conversion as part of a broader property improvement also ask us about exterior projects while we’re on site; it’s not unusual for us to end up discussing Metal Roofing in Alva or Tile Roofing in Alva once they see the quality of our interior work.

Frequently Asked Tub-to-Shower Conversion Questions in Alva
Most tub-to-shower conversions in Alva take 5 to 8 working days. Demolition and rough-in happen in the first two days, waterproofing and wall assembly take another two, and tile, trim-out, and glass installation fill days 5 through 8. If you select a solid-surface wall system instead of tile, the timeline compresses to roughly 5 days because there’s no curing or grouting step. If the subfloor needs repair or the drain must be relocated across a concrete slab, add a day for each. A permit inspection may add a scheduling gap, and we build that into the timeline before we start so you’re not caught off guard. Call (844) 638-7249 to get a timeline quote specific to your bathroom.
Yes. A tub-to-shower conversion in Lee County requires a plumbing permit because you’re altering the drain size and reconfiguring the water supply connections. If the job involves any structural changes, cutting into a concrete slab to move the drain, or relocating a wall, an additional building permit may be required. We pull all permits on your behalf, the cost is included as a line item on your estimate, and we coordinate the inspection so the work is signed off before we consider the job complete.
Yes, and most of the tub-to-shower conversions we complete in Alva keep the existing drain and supply locations. The original tub footprint gives you a shower base that’s roughly 30 by 60 inches, which is a comfortable walk-in size. Keeping the plumbing in place avoids concrete cutting, joist modifications, and the additional material cost of extended drain lines. If you want a larger shower or a different orientation, we can relocate the plumbing, but the cost moves toward the higher end of the $3,500 to $10,000 range. We’ll walk you through the trade-off during the estimate.
It covers the workmanship and the materials we install for two full years from the day the job is finished. If a tile cracks, a grout line fails, the shower pan leaks, or a fixture we installed stops operating correctly, we come back and make it right at no charge. The manufacturers of the products we use, Kohler, Delta, Onyx, Schluter, and others, carry their own warranties that extend beyond our two-year window, and we register those on your behalf at completion. The promise is simple: if it’s not done right, we make it right.
For a straightforward tub-to-shower conversion in Alva using a mid-grade acrylic or solid-surface wall system and a framed glass door with the plumbing staying in its current location, budget $5,500 to $7,000. If you want a fully tiled shower with a custom pan, a frameless glass enclosure, and upgraded fixtures, plan for $7,500 to $9,500. A curbless shower with drain relocation on a slab foundation can reach the $10,000 mark. Every estimate we provide is a written, line-item price, not a range with fine print below it, so you’ll know exactly where your number lands before you commit to anything.
