Angela's team gutted our 1970s hall bath and turned it into a spa. Zero-threshold shower, Schluter waterproofing, linear drain, perfect tile lines. They hit the schedule and stayed on budget.

Hicksville, NY · Full Bathroom Remodel
We converted our tub to a curbless walk-in for my mother-in-law. Island Bath handled the Nassau County permit and everything was inspected clean. Grab bars where we asked, fold-down bench. Worth every dollar.

Tile work is art with these guys. Calacatta mosaic floor, Carrara subway walls, all perfect lines. Two full days of dry-fit before any thinset hit the board.

Before you call
The seven questions we answer most.
On Long Island, a full bathroom renovation typically runs $18,000–$45,000 for a hall bath and $30,000–$80,000+ for a master bath, depending on scope, tile choice, and fixture quality. We walk every project on-site and give a firm, itemized number. No ballparks, no surprises.
Most hall-bath remodels take 3–4 weeks from demo to final walkthrough. Master baths with plumbing relocations or custom tile run 4–6 weeks. We dedicate one crew to your project — we don't start three jobs and disappear.
Yes, if the work includes plumbing, electrical, or structural changes (tub-to-shower conversions, wall relocations, new venting). We pull the permit and manage the inspection for you. Cosmetic-only jobs (tile, vanity, fixtures) usually don't need one.
Schluter-Systems Kerdi sheet membrane or Kerdi-Board on every shower wall and pan. We're Schluter-Certified installers. No mesh-tape-and-hope jobs, no black-paint-on-cement-board shortcuts.
Yes. Curbless showers, reinforced grab-bar blocking, comfort-height toilets, wider 36" doorways, handheld sprayers, fold-down bench seats. Founder Angela Ferreira specializes in accessible design.
Yes. Nassau County HIC #H2419300 and Suffolk County License #53120-H. $1,000,000 general liability plus workers' comp. Certificates available before work begins.
