Curbless Shower Conversion in Brevard County, FL

Curbless showers (no step over a threshold) are increasingly the default choice for Brevard primary bathroom remodels. They look modern, work for any age or ability, are easier to clean, and dramatically improve aging-in-place compatibility. The main technical challenge is drainage - water has to go somewhere when there's no curb to stop it.

How Curbless Drainage Works

Three drainage approaches: (1) Linear drain along the shower wall or in the floor entry zone, with the shower floor sloped toward it - cleanest aesthetic. (2) Centered traditional drain with 4-way slope to the drain - lowest cost but more visible slope. (3) Trench drain at the entry threshold to catch water before it leaves the shower zone.

Brevard's typical concrete-slab construction works well for curbless because we can chip down the slab in the shower area to create the depression for drainage. Wood-frame construction requires more substantial subfloor work.

Waterproofing Requirements

Curbless showers MUST have flawless waterproofing because there's no curb to contain water if the system fails. Schluter Kerdi membrane is the standard. Any seam, penetration, or corner gets special treatment. The waterproofing extends out beyond the shower zone by 6-12 inches to handle splash.

Cost of Curbless Shower Conversion

Standard tub-to-curbless-shower conversion: $8,000-16,000 depending on size and finish. With higher-end tile and premium fixtures: $14,000-25,000. The curbless premium over a curbed shower is typically $1,500-3,500 due to the additional slab work and drainage requirements.

Aging-in-Place Benefits

No threshold = no tripping hazard. Easy entry with a wheelchair or walker. Can install grab bars on multiple walls easily. Comfort-height bench or fold-down seat option. Handheld showerhead on slider for seated use. These features work for everyone today and accommodate any changes that come later.

Curbless Shower Slab and Permit Questions

Does lowering the slab for a curbless shower need a permit?

Moving or replacing the shower drain and recessing the floor is plumbing work, and Brevard building departments permit and inspect it, typically with a rough plumbing inspection before the floor is closed up. Ask where the new drain will tie in and whether the waterproofing will be flood-tested before tile. A failed test costs hours, while a leak found after tile costs the whole floor.

Is a curbless shower worth it if no one needs it yet?

For many homeowners, yes, because the slab only has to be opened once. Building the recessed floor, linear drain, waterproofing and grab-bar blocking during a planned remodel avoids tearing out a new shower later when mobility changes. Census data puts the median Brevard home at 1987 (U.S. Census Bureau, ACS 2019-2023 5-year, table B25035), so many original tub-shower combinations are reaching the age where a full conversion makes sense.

Who issues the permit for a curbless shower conversion in Brevard County?

It depends on where the house sits, not on the mailing address. Homes inside one of Brevard's 16 incorporated cities and towns, such as Melbourne, Palm Bay, Titusville or Cocoa Beach, are permitted by that municipality, while unincorporated areas such as Merritt Island, Viera, Suntree and Mims go through Brevard County in Viera.
