Full bathroom remodels in West Islip — gut renovations, accessible upgrades, and master suite baths — designed and built by one in-house team with all permits managed.
West Islip's ranch and split-level homes typically have one and a half to two baths, often with an upper-level full bath that has not been touched since the original build. Those bathrooms — small footprints, single-sink vanities, fiberglass tub surrounds — no longer serve households the way homeowners want. Adding a second sink, converting a tub to a curbless shower, or reconfiguring the layout to add square footage all require plumbing and electrical permits through the Town of Islip.
Milton's Construction handles bathroom remodels from start to finish: demo, waterproofing, plumbing rough and finish, electrical, tile, cabinetry, and fixtures. On South Shore homes in West Islip, proper waterproofing is not optional — the combination of high water table in low-lying areas, ambient humidity from the bay, and the freeze-thaw cycle means a bathroom that was not waterproofed correctly will fail. We use sheet-membrane and mud-bed systems under tile that hold up.
The most common bathroom projects we do in West Islip split-levels are full gut renovations of the upper-level hall bath and conversion of a half-bath to a full bath on the lower level. Both involve plumbing changes that require a Town of Islip permit and a rough-in inspection before walls close. On the lower level, proximity to the slab — and in flood-zone homes, to the minimum habitable floor elevation — affects drain depth and sometimes requires a sewage ejector pump instead of a gravity drain.
Master bath additions in West Islip ranches and Capes are also popular. Many families are adding a private bath off the primary bedroom, which often means taking space from an adjacent closet or expanding the footprint into a bump-out addition. We design the layout, handle the structural work if the exterior expands, and complete the full finish — tile, glass enclosure, vanity, and lighting.
A basic West Islip bathroom refresh — new vanity, toilet, fixtures, and fresh tile in an unchanged layout — typically costs less than a full gut renovation. Full gut renovations with plumbing relocation, a new shower enclosure, and custom tile work on Long Island's South Shore generally run between $18,000 and $45,000 depending on size, materials, and whether any structural or drainage changes are needed. Master bath additions that involve a bump-out or structural work run higher.
These are ranges that help you plan, not quotes. The accurate number for your specific bathroom in your specific West Islip home comes from a written estimate. Call or text 631-741-0199 to schedule one — it is free and there is no obligation.
Yes, for any work involving plumbing changes or electrical work — which includes almost every full remodel. The Town of Islip Building Division issues the permit and requires a rough-in inspection before walls are closed. We file and manage all of that. Unpermitted plumbing work surfaces at resale and can kill a deal.
In West Islip, especially on flood-zone lots south of Montauk Highway, lower-level drains may be at or near the minimum elevation for gravity drainage to the municipal sewer. When that is the case, a sewage ejector pump is the correct solution. We assess the drain depth during the estimate and build the right system into the scope from the start.
Yes. We do this regularly — taking space from an adjacent closet for a modest master bath, or adding a small bump-out to the exterior to create more room. Both approaches require Town of Islip permits. The bump-out option also requires a plot plan and may trigger DEC review on waterfront lots. We handle all of it.
