Bathroom Renovation in Hauppauge, NY

Suffolk County Building Department requires a permit for any project involving plumbing relocation, electrical upgrades, or structural changes (moving a wall, enlarging the bathroom footprint). Cosmetic refreshes — tile only, vanity swap, fixture replacement with no pipe moves — typically don't need one. We pull the permit on your behalf, coordinate all inspections, and deliver a closed permit card at job completion. This matters for your homeowner's insurance and for resale.

Our current backlog runs 6–10 weeks from contract signing to crew start. If you have a hard deadline — a relative moving in, a home sale, a contractor window — tell us at the estimate stage and we'll do our best to sequence accordingly.

Standard hall bath full gut-and-rebuild: 3–4 weeks. Master bath renovation: 4–6 weeks. Tub-to-shower conversion only (no full gut): 2–3 weeks. Shower-only tile rebuild: 2–3 weeks including frameless glass. Accessible bath retrofit: 3–4 weeks. Timeline starts the day the permit is in hand.

Yes. Island Bath Studio holds Suffolk County HIC #HI-69024 and carries $1,000,000 General Liability plus Workers' Compensation. We are also EPA Lead Renovation Certified. We provide our license number and certificate of insurance before any contract is signed.

Usually yes. Anything that moves a drain, adds a circuit, or changes structure needs a permit from the Town of Smithtown Building Department. A like-for-like cosmetic refresh with no pipe moves generally does not. We pull the permit, schedule the rough and final inspections, and hand you a closed permit card at completion, which matters at resale.

A full hall bath gut and rebuild in Hauppauge typically runs $11,000 to $22,000 including PEX supply, PVC drain, Schluter waterproofing, tile, vanity and fixtures. A primary bath with a walk-in shower and double vanity typically runs $20,000 to $38,000. A tub-to-shower conversion on its own typically runs $8,500 to $16,000. We give you a fixed number after an on-site walk, not before.

Most hall bath rebuilds run three to four weeks on site. Primary baths with plumbing relocations or stone work run four to six weeks. Shower-only rebuilds run two to three weeks including frameless glass lead time. Permit approval is separate and typically adds one to two weeks before the crew can start, so we file straight after contract signing.

On any bathroom built before about 1990 we recommend it. Older supply lines scale and corrode from the inside, and a hidden pipe failing behind brand new tile is the worst outcome in this trade. During a full remodel we replace in-wall supply with PEX and the in-wall drain section with PVC, and we show it as a separate line item so you can see exactly what it costs.

Porcelain, in almost every case. It is non-porous, needs no sealing, and handles Long Island's humidity swings year-round. Natural stone is workable but we seal it at install and give you a maintenance schedule. The bigger issue in older Hauppauge bathrooms is never the tile itself, it is the waterproofing behind it. We use Schluter Kerdi sheet membrane on every shower without exception.
