Walk-In Shower Installation
Walk-In Shower Installation in Sarasota, Built for CBS Construction and Gulf Coast Humidity.
A walk-in shower installation in Sarasota has to do more than look good in photos, it has to hold up against 70-90% humidity for most of the year without the grout going dark or the drywall behind it turning soft. We build it right the first time: proper slope, continuous membrane, large-format porcelain, and ventilation sized for this climate.

Quick Answer
How much does a walk-in shower installation cost in Sarasota?
As part of a mid-range bathroom remodel, a new walk-in shower typically runs $15,000-$36,000 alongside a new vanity and fixtures. As a standalone conversion from an existing tub, it runs $8,000-$22,000. Code allows a shower as small as 30"x30", but most Sarasota homeowners land between 48"x36" and 60"x36" for a walk-in that doesn't feel cramped day to day.
Why This Comes Up So Often Here
A Curbless Shower on a CBS Slab Isn't the Same Job as Up North
Most of Sarasota's older housing stock sits on a concrete slab with cinder block (CBS) walls, not a wood frame over a crawlspace. That changes how a curbless walk-in shower actually gets built. Without a crawlspace to drop the drain into, getting a zero-threshold entry right usually means either building up the surrounding floor slightly or recessing the slab itself at the drain point, so water still slopes the right direction without a curb to stop it. Skip that step and a curbless shower either doesn't drain properly or ends up flooding the bathroom floor every time someone showers, we've seen both from previous DIY attempts. Building one for accessibility? See our aging-in-place bathroom remodel guide for seat heights, grab bar placement, and roll-in sizes. Planning for someone coming home from the hospital? Start with bathroom changes after surgery or injury.
The humidity here changes the material conversation too. We steer people firmly away from pebble shower floors and small mosaic tile, no matter how good they look in a showroom, both trap soap scum and moisture in the grout in ways that show up as mildew within a year or two in Sarasota's climate. Large-format porcelain (12"x24" and bigger) means far fewer grout lines for that buildup to happen in the first place, and porcelain itself absorbs less than 0.5% water by weight versus 3-7% for ceramic, a real, measurable difference in a shower that's wet for an hour a day, every day, year-round.
Ventilation matters as much as the tile. A standard 50 CFM exhaust fan, the kind that's fine in a drier climate, doesn't clear Sarasota's humidity fast enough after a shower, the moisture just lingers and finds its way into grout and drywall it shouldn't. We size for at least 110 CFM in a standard bath, more in a larger primary bathroom, as a baseline on every walk-in shower install, not an upsell.

Sizing It Right
What Size Walk-In Shower Actually Feels Comfortable?
Code minimum passes inspection. It doesn't mean it's a size you'll be happy showering in for the next fifteen years.
| Size | Fits Code? | Realistic Take |
|---|---|---|
| 30"x30" | Yes, code minimum | Passes inspection, feels genuinely tight to use daily |
| 36"x36" | Yes | Workable minimum for a single-user bathroom |
| 48"x36" to 60"x36" | Yes | The practical sweet spot most homeowners land on |
| 60"x36"+ | Yes | Best for a curbless entry with real maneuvering room |
How We Handle It
What a Walk-In Shower Installation in Sarasota Actually Looks Like
Layout & Slope Plan
We plan the drain location and floor slope first, especially on a CBS slab, before anything gets demoed.
Permit & Demo
We pull the plumbing and building permit, then demo the old tub or shower down to the studs and slab, the same first step as a tub-to-shower conversion.
Pan, Membrane & Tile
Cement board, a continuous waterproofing membrane, and large-format porcelain installed with a properly sloped pan.
Glass, Fixtures & Inspection
Glass enclosure or curtain, fixtures, humidity-rated ventilation, and the final county inspection scheduled by us.
What We Use
Materials Chosen for Sarasota's Climate, Not Just the Showroom
Large-Format Porcelain
12"x24" and up, absorbing less than 0.5% water by weight. Fewer grout lines means fewer places for humidity-driven mildew to take hold.
No Pebble Floors, No Small Mosaics
Both trap soap scum and moisture in ways that show up fast here. We'll steer you away from them even if they look great in the showroom.
Continuous Waterproofing Membrane
Sheet or liquid-applied, chosen based on the shower's geometry, no gaps at corners, curbs, or the drain, full stop.
110+ CFM Ventilation
A standard 50 CFM fan isn't sized for Sarasota's humidity. We install at least 110 CFM as our baseline on every walk-in shower installation, more in larger primary bathrooms.
Questions We Get
Walk-In Shower Questions from Sarasota Homeowners
A new walk-in shower installed as part of a mid-range bathroom remodel typically runs $15,000-$36,000 alongside a new vanity and fixtures. As a standalone tub-to-shower-style conversion, a walk-in shower on its own runs $8,000-$22,000, depending on size, tile, and whether the drain needs to move.
Florida Building Code allows a shower as small as 30 inches by 30 inches, and that passes inspection fine, but it feels genuinely cramped to use every day. Most homeowners and contractors land on something between 48x36 and 60x36 inches as the practical comfortable minimum, especially for a curbless design where you want room to maneuver without a curb to define the wet area.
Porcelain, by a wide margin. It absorbs less than 0.5% water by weight compared to 3-7% for ceramic, and large-format porcelain (12x24 inches or bigger) means fewer grout lines for mold and mildew to take hold in. We steer people away from pebble shower floors and small mosaic tile in this climate specifically, both trap soap scum and moisture in ways that show up within a year or two of humid Sarasota use.
Yes, in almost every case. A walk-in shower install typically involves moving or reconfiguring plumbing (especially for a curbless pan, which needs a specific slope built into the subfloor) and often changes the wall structure where a tub used to be. That's a Sarasota County or City of Sarasota plumbing and building permit, which we pull and manage as part of every installation.
Yes, and it's actually a common Sarasota scenario. A curbless entry needs the floor built up slightly around the shower's perimeter, or the slab recessed at the drain, to get the slope right without a curb, that takes more planning on a slab-on-grade CBS home than a wood-frame house with a crawlspace, but it's routine work for us and doesn't rule out a curbless design.
