How We Convert a Tub to a Shower, Step by Step

Every tub-to-shower conversion follows a sequence that hasn’t changed much in decades, but what surprises most homeowners is how many decisions happen in the first 48 hours. Here’s exactly what to expect when our crew arrives in Manasota Key.

Day 1: Demolition and the First Honest Look

We remove the existing tub, surround, and valve - typically one full day, sometimes a day and a half on older Manasota Key cottages where the original cast-iron tub was set in a mortar bed. Once the walls are open, we inspect the framing, subfloor, and plumbing. This is the moment where we either confirm the initial estimate or flag issues nobody could have seen before demo. Rot from a slow drain leak, termite damage in the bottom plate, or corroded galvanized supply lines are the three most common findings on Gulf-side homes built between 1955 and 1975. You’ll get photos and a real-time update before we proceed with any change to scope.

Day 2-3: Rough Plumbing and Pan Set

If the drain stays in the tub’s original location, the plumber moves the drain pipe to center the new shower pan - code requires a 2-inch drain line for showers versus the 1½-inch line many old tubs used, so swapping that line is non-negotiable. The shower valve gets roughed in at this stage, and we set the shower pan on a level mortar bed. On elevated stilt homes built post-Andrew, we’re working on plywood subfloor, which is straightforward. On the older slab-on-grade cottages along the Lemon Bay side, we sometimes find the original slab was poured without a vapor barrier, which means we add one before the pan goes down. This stage runs one to two days depending on plumbing complexity.

Day 4-5: Wall Surround, Waterproofing, and Curb

Backer board goes up, seams get taped and sealed, and a full waterproofing membrane - liquid-applied or sheet membrane, both meet Florida Building Code for coastal zones - covers the walls and pan-to-wall transitions. If you’ve chosen a tile surround, the tile setter spends these two days laying wall tile, building the curb, and fitting any niche or bench. Acrylic or solid-surface surrounds install faster, usually in a single day. We schedule the rough-in inspection with the county at this point; on Manasota Key, depending on which side of the county line you’re on, that’s either Sarasota or Charlotte County building department. We know which portal to use.

Day 6: Glass, Trim, and Fixtures

The shower door or glass panel gets measured and installed - frameless glass is a custom-order item, so we templated it on day 3 and it arrives for fitting now. Trim plate, showerhead, and controls go on. If you’re adding a handheld sprayer or a linear drain, this is the day those get finalized. We test the pan for drainage and check every seal.

Day 7: Final Walkthrough and the 730-Day Promise

We walk the finished shower with you, demonstrate the valve and door operation, and confirm every joint is sealed. You get a written close-out that includes product warranties and our 730-Day Done Right Promise - if anything isn’t right, we make it right, no fine print and no debate. Most conversions wrap in five working days; tile-heavy jobs with custom glass push closer to seven.

The Choices That Shape Your Shower

The single biggest decision in a tub-to-shower conversion in Manasota Key isn’t tile color - it’s whether you’re keeping the original footprint or opening up the walls. Here are the spec choices every homeowner weighs, with the honest trade-offs.

• Acrylic or solid-surface surround: One-piece or multi-piece panels that install in a day. No grout lines means no mildew scrubbing, and they handle the salt-air humidity of Manasota Key without degrading. Lower cost end of the range, but limited to stock sizes and colors. If your opening is a non-standard width - common in 1960s cottages - you’ll need a custom surround or tile.
• Tile surround with cement board and waterproofing: Unlimited design flexibility, and a properly waterproofed tile shower lasts 30+ years in coastal conditions. The trade-off is cost and time - tile adds two to three days of labor and moves the price toward the upper half of the $3,500-$10,000 range. We use Quikrete or Sakrete mortar beds and polymer-modified thinset rated for high-moisture environments. Grout gets sealed twice before we hand it over.
• Shower pan material: Acrylic pans are lightweight, affordable, and never need resealing. Tile-over-mud pans feel custom and can be sloped to any drain configuration, but they require periodic grout and seal maintenance. On a barrier island with salt mist coming off both the Gulf and the Bay, we lean toward solid-surface pans for lower maintenance - but a tile pan with epoxy grout closes the maintenance gap considerably.
• Glass enclosure type: Framed sliding doors are the budget choice. Frameless hinged or sliding glass costs more - $800 to $2,200 depending on size and glass thickness - but it opens up a small bathroom visually and seals with PVC sweeps that don’t corrode. Every glass panel we install on Manasota Key gets stainless steel hardware, never chrome-plated zinc, because the salt air eats zinc-plated hinges within two years.
• Valve and showerhead upgrades: A pressure-balanced single-handle valve comes standard and meets code. Thermostatic valves with separate volume control add $300-$600 but give you precise temperature control - helpful when someone flushes a toilet elsewhere in an older plumbed cottage with pressure swings. Rain heads, handheld sprays, and body jets are all options that add labor time for additional rough plumbing.

What Tub-to-Shower Conversion Costs in Manasota Key, FL

A tub-to-shower conversion in Manasota Key runs $3,500 to $10,000. That’s the range for a standard 5-foot tub alcove converted to a shower, with all labor, materials, permits, and debris removal included in writing before the job starts. Here’s what separates the low end from the high end.

Drain location. If the shower drain stays where the tub drain was, plumbing cost is minimal. If you want the drain centered in the new pan - which requires cutting the slab or reworking the joist bay - plumbing labor jumps by $400 to $900. On older slab-grade Manasota Key homes, cutting concrete adds dust, time, and cost.

Surround material. A stock acrylic surround with a matching acrylic pan runs $3,500-$5,500 installed. Mid-range tile with a solid-surface pan lands at $5,500-$7,500. Floor-to-ceiling tile, custom niches, a frameless glass door, and a thermostatic valve push the job to $8,000-$10,000.

What we find inside the walls. On Manasota Key cottages built in the 1950s and 1960s, we sometimes open the wall to find the original galvanized supply lines have corroded to half their diameter. Replacing those with PEX or copper adds $400-$800 but prevents a future leak behind a brand new shower - and we won’t bury old pipe that’s on its last legs, because our 730-Day Done Right Promise means we stand behind what we leave behind.

Permit scope. A straightforward like-for-like swap with no structural changes usually falls under a simple plumbing and building permit - $150-$350 depending on which county jurisdiction applies. If the inspection reveals the need to bring the shower up to current flood-elevation or wind-load requirements (rare for interior remodels, but possible if the bathroom abuts an exterior wall being re-sheathed), the permit cost and scope increase. Every estimate we write includes the permit line item specific to your property’s jurisdiction - Sarasota or Charlotte County, depending which side of the county line your lot falls on.

Debris removal and access. Manasota Key has limited bridge access, and debris hauling costs run slightly higher than mainland jobs. We factor that into every estimate on the island. Our price includes full cleanup - no dumpster left in your driveway for two weeks, no drywall dust migrating to the living room.

How Manasota Key Homes Change This Job

Manasota Key isn’t one jurisdiction - it’s two. The county line splits the island with no visible marker, and a home on the north end falls under Sarasota County permitting while a home three lots south falls under Charlotte County. For a tub-to-shower conversion, that means the permit application, inspection scheduling, and fee schedule are entirely different depending on which side of the line you’re on. We keep contractor registrations current in both counties, so your permit gets pulled from the right office the first time. That sounds basic, but we’ve been called in to fix jobs where an out-of-area crew filed with the wrong county, triggered a stop-work order, and left the homeowner with an open permit and a half-finished bathroom for weeks. Our crew knows before they arrive which portal to log into.

The housing stock here also shapes the work. Most original Manasota Key homes are mid-century cottages - 1950s through 1970s - built before modern waterproofing standards existed. When we open the wall behind a 1965 tub, we regularly find green board or even regular drywall instead of cement board, and nothing resembling a waterproofing membrane. That’s not a surprise to us; it’s what we expect. We strip it to the studs, inspect for moisture damage, replace any compromised framing, and rebuild with cement board and a full membrane system that meets the Florida Building Code for coastal high-hazard areas. The salt-laden air from both the Gulf and Lemon Bay accelerates corrosion on any metal that isn’t stainless, so every fastener, screw, and hinge we spec is rated for coastal exposure. Chrome-plated hardware that lasts 15 years inland starts pitting here in three.

Many homeowners use a tub-to-shower conversion as part of a broader Bathroom Remodeling in Manasota Key , especially on older cottages where the bathroom layout was designed around a tub that nobody uses. Our Bathroom Remodeling crew often coordinates a shower conversion alongside vanity replacement, flooring, and lighting upgrades in a single project phase, which is more efficient than doing each trade separately.
