Co-op and condo bathroom renovation with board-ready process
Renovations built around NYC alteration agreements, board architect review, certificates of insurance, and house-rule work hours. Water damage to neighbors is why boards scrutinize wet-area work — waterproofing documentation is part of the job, not paperwork theater.
NYC Bathroom Remodeling runs co-op and condo bathroom renovations across Manhattan, Brooklyn, Queens, and the Bronx with sequencing that waits for required approvals before demolition.
Board packages and alteration agreements
Typical co-op/condo packets ask for drawings or finish specs, plumber/electrician credentials as the building defines them, insurance certificates meeting stated limits, and work-hour / demolition rules. We help owners assemble what the building asks for. We do not invent license numbers, DOB filing claims, or “guaranteed approval” timelines — board calendars vary from a few weeks to much longer.
When a board architect comments on waterproofing or stack work, responding to those comments is part of the critical path. Construction follows the approved package.
Stack access in multi-family buildings
Shared wet stacks, shaft walls, and occupied units below change demo and rough-in:
- Toilet and shower drains often must stay on existing roughs
- Opening ceilings for traps or valves needs neighbor and management coordination
- Cast-iron stacks and old galvanized branches show up after demo — allowances beat fake certainty on a first call
- Freight elevator booking and hallway protection are daily requirements, not extras
Waterproofing and inspection hold points
Many condo buildings require membrane inspection before tile. Co-ops vary. We schedule hold points so tile is not installed prematurely:
- Continuous membranes at showers and wet floors
- Documented details when the board requests them
- Flood/water tests before finish work
- Protection paths for common halls and elevators

FAQ
Why do boards care about bathrooms?
Leaks affect neighbors and common elements. Boards want documented waterproofing, insurance, and licensed trade work as their rules define it.
How long can alteration approval take?
From a few weeks to much longer. We do not start demolition until required approvals exist.
Do you work with the board architect?
Yes — responding to comments is part of co-op/condo jobs.
Can I use my own fixtures?
Usually, if they meet the approved scope. Long-lead owner-supplied items must arrive before they sit on the critical path.
Do you publish fake permits or reviews?
No. This page sticks to process and building realities.

Common Questions
Frequently Asked Questions
Can we move the toilet or shower drain in a NYC condo?
Sometimes — only if the stack and slab/joist conditions allow, and the building approves opening floors/ceilings. Many remodels keep drains and change finishes/layout above the rough.
Is a waterproofing inspection required?
Many condo buildings require membrane inspection before tile. Co-ops vary. We schedule the hold point into the calendar so tile is not installed prematurely.
How long is a typical full gut bathroom?
Often 2–4 weeks for a single hall bath after fixtures arrive; glass and specialty tile can extend.
Tub-to-shower: what usually blocks it?
Existing drain location, curb height vs joists, and whether a bench/niche needs wall reframing.
Do you handle mold remediation if found?
Minor surface issues may be in scope; extensive remediation is a specialist — we stop and document if discovered.
What warranty covers labor vs materials?
Labor warranty period stated on proposal; fixtures/tile follow manufacturer warranties. Exact terms not invented here — owner to confirm before publish.
