Powder rooms to spa-grade primary suites — waterproofed to last, wrapped in honed stone, and detailed with the calm of a private retreat.
A bathroom is the hardest room to build well. Every surface meets water, every joint is seen up close, and the work behind the wall matters as much as the stone in front of it. We build bathrooms that are watertight, quiet, and finished to a high standard, and that stay that way for decades.
As one design-build firm, we coordinate waterproofing, stone, plumbing, and lighting from the first drawing, so the finished room is both comfortable and a sound investment in the home.
From a powder room to a full primary suite, the scope is planned around the room, the plumbing, and the apartments below it.
The invisible work that defines a serious bathroom — fully bonded waterproofing membranes, sloped substrates, and detailing built to protect the apartments below.
Slab-selected, book-matched marble and stone for walls, floors, and showers, with large-format porcelain and hand-set mosaics laid out to align.
Bespoke vanities in wood, stone, and mixed materials, engineered for moisture and coordinated with integrated medicine cabinets, niches, and concealed storage.
Spa-grade fixtures, radiant heated floors, steam and rainfall showers, frameless glass, and the rough-in to support them — selected and integrated as one.
Bathrooms carry the highest risk in a New York renovation. One waterproofing failure can damage the apartments below and your standing with the building. We build to wet-over-dry rules, carry the plumbing permits and insurance, and document the membrane and inspection sign-offs your building requires.
We manage co-op and condo alteration agreements, house rules, and work-hour windows, and we protect common areas throughout, so the bathroom is delivered without friction with the board.
Every bathroom runs through our four-phase process — discovery, design, build, delivery — under one project manager and a client portal with itemized pricing. Stone selections, tile layouts, and fixture schedules are confirmed before demolition begins.
Our waterproofers, stone setters, and plumbers are long-standing partners held to one standard, so grout lines align, slabs book-match, and the room is sealed to protect both your suite and your neighbors.
Bathrooms sit above other people's bathrooms, so co-op boards pay close attention to waterproofing, drain connections, and the building's shared risers. The alteration agreement usually requires a licensed plumber, a Department of Buildings plumbing permit, and an inspection of the waterproofing membrane before tile goes down. Adding a bathroom where none exists is often limited by wet-over-dry rules.
Condo boards review the same plumbing drawings and insurance certificates. Newer buildings usually have a documented finish standard and a specific waterproofing detail that the building engineer expects to see repeated, and the managing agent controls when the water can be shut off for a riser tie-in.
A townhouse bathroom has no downstairs neighbor in another apartment, but it does have the floors below and the original joists. Moving a bathroom means new drain runs through old framing and a Department of Buildings plumbing permit. In a historic district, adding a vent or a window on a visible facade goes to the Landmarks Preservation Commission.
Houses in Queens and the Bronx need plumbing and electrical permits but no board review. Hamptons bathrooms are approved by the village or town building department, and a larger house may involve the county health department if the septic system changes. Westchester and Long Island projects follow the local building department.
We discuss what the bathroom needs to do and who uses it. On site we check the drain locations, the riser, the floor structure, and the ventilation, and we read the alteration agreement for the building's waterproofing and plumbing requirements.
The room is drawn with the tile layout, the vanity, the glass, and the fixtures placed to the inch. You approve the stone, the tile, and the fixture schedule, and the itemized proposal is priced from those selections before anything is ordered.
We prepare the board package and insurance certificates, then file the Department of Buildings plumbing permit and the electrical permit. Stone and fixtures are ordered as soon as the drawings are approved, since slabs and fixtures usually take longer than the permits.
The old bathroom is removed down to the substrate. New drains, supply lines, and electrical are installed and inspected. The waterproofing membrane is applied, flood-tested, and documented for the building before any tile is set.
Stone and tile are set to the approved layout, then the vanity, the glass, the fixtures, and the lighting are installed. We complete the plumbing sign-off, walk the room with you, and hand over the fixture documentation and warranties.
What the wet-over-dry rule is, why co-op and condo boards enforce it, what counts as a wet area, when a kitchen or bathroom relocation can be approved, and how to plan a layout around it.
