Nassau County bath specialists

1.4 million residents. One bathroom crew you can actually trust.

Nassau County's housing stock spans 80+ years — postwar Levittown ranches, Garden City colonials, Great Neck estates, hi-ranches and splits built through the 80s, and new construction mixed throughout. We've worked in every style. Our specialty is bringing old bathrooms forward: out go cast iron drains, galvanized supply lines, fiberglass tub surrounds, and 50-year-old subway tile; in go PEX, PVC, Schluter waterproofing, large-format porcelain, frameless glass, and modern fixtures.

Nassau County permits are a routine part of our workflow. We file same-day when contracts sign, coordinate inspections, and hand you a closed-out permit at the end. Village permits (Garden City, Great Neck, Rockville Centre, Old Westbury, etc.) — also handled.

Nassau County FAQs

Questions from Nassau County homeowners.

All of them. Our core list includes Hicksville, Garden City, Great Neck, Levittown, Massapequa, Mineola, Syosset, Plainview, East Meadow, Bethpage, Westbury, Rockville Centre, Oceanside, Wantagh, and many more. If you're in Nassau, we'll come estimate.

Nassau County requires a permit for any bathroom project involving plumbing relocation, electrical changes, or structural work. We file online with the County, coordinate rough and final inspections, and hand you a closed-out permit at the end.

3–4 weeks for a hall bath, 4–6 weeks for a master bath, 2–3 weeks for a shower-only or tub-to-shower conversion. Permit filing adds about 10 days upfront.

Yes. Garden City, Great Neck Estates, Kings Point, Old Westbury, Rockville Centre, and other incorporated villages have their own building permits in addition to or instead of the County. We handle village submittals too.

Hall baths run $18,000–$45,000 in Nassau County. Master baths run $30,000–$80,000+. We walk every project on-site and quote firmly within 48 hours.
