A full bathroom renovation in a NYC apartment usually takes about 2 to 4 months from first design meeting to first shower, and most of that time passes before anyone swings a hammer. Board review commonly takes 3 to 8 weeks and DOB filings 2 to 6 weeks, according to Havard Cooper Architect. Construction itself is the short part: published NYC figures run 3 to 6 weeks, and at Euro Restoration a bathroom typically takes 1 to 2 weeks of construction once approvals are in and materials are on site.
The bathroom renovation timeline at a glance
Every building is different, so treat these ranges as typical, not guaranteed.
| Phase | Typical time | What decides it |
|---|---|---|
| Design and selections | 2 to 4 weeks | How fast you choose tile, vanity, fixtures and glass |
| Board and building architect review | 3 to 8 weeks | Meeting schedule, completeness of the package, whether the building uses its own architect |
| DOB filing and permits | 2 to 6 weeks | Scope of work; permits are not issued until the board signs off |
| Material ordering | Overlaps approvals | Lead times on vanities, special order tile, fixtures |
| Demo and protection | 1 to 2 days | Building rules on debris removal and elevator use |
| Rough plumbing and electrical | 2 to 4 days | Whether fixtures move, condition of old pipe |
| Inspections | Varies | Whether the job is filed with DOB and when inspectors are available |
| Walls, waterproofing, flood test | 2 to 4 days | Membrane system and test time |
| Tile | 3 to 6 days | Tile size, pattern, niches, heated floors |
| Fixtures, vanity, glass | 2 to 5 days, plus glass lead time | Shower glass is measured after tile is set |
| Punch list | About 5 days | Small fixes, caulk, touch ups |
Block Renovation's own data, reported by Brick Underground, put a typical project at about 55 days overall, or 70 to 75 days in a co-op or condo. Brick Underground's broader guide says about 4 months is common for a bathroom start to finish.
Before construction: approvals and permits
Board review and the alteration agreement
In a co-op or condo, you submit an alteration application with plans, scope, contractor insurance and licenses. Havard Cooper Architect puts board review at 3 to 8 weeks, longer when the building sends plans to its own architect or engineer. Some boards meet monthly, so missing a submission deadline can cost you a full month. Our guide to the co-op alteration agreement lists what is usually in the package.
The agreement also sets the clock. Havard Cooper Architect notes that alteration agreements commonly allow 90 to 120 days to finish the work and often require you to start within 30 days of approval. Many co-ops fine owners daily for running over, so do not start the clock until everything is ready.
DOB filings
A like for like replacement of fixtures can often be handled by a licensed master plumber without a full alteration filing. Moving fixtures, changing walls or adding a bathroom is a bigger filing with plans. The NYC Department of Buildings only lets licensed trades such as master plumbers file Limited Alteration Applications for plumbing work. Havard Cooper Architect puts DOB permit filing at 2 to 6 weeks, and permits are not issued until the board has approved.

Work hours
Most buildings allow work on weekdays, typically 9 a.m. to 5 p.m., with no weekends or holidays (Havard Cooper Architect). Some only allow major work in summer. Water shutoffs to the riser usually have to be scheduled with the super, which can only happen during those hours.
Construction, phase by phase
Demo
The old tile, tub, vanity and often the subfloor come out. Hallways and the elevator get protected first, and debris leaves the same day in most buildings. This is when you find out what is behind the walls.
Rough plumbing and electrical
New supply and drain lines, valves, the shower body, outlets, lighting and fan wiring go in. Many buildings require replacing branch lines and shutoff valves whenever plumbing is opened, which can add a day or two. If you are relocating a toilet or shower, your building's wet over dry rule decides what is allowed.
Inspections
If the work is filed with DOB, rough plumbing has to pass inspection before walls close. Brick Underground budgets at least a week for inspections on larger renovations, and a failed inspection can mean reopening walls. Some buildings also send their architect or super to look before anything is covered.
Waterproofing and flood test
Cement board or foam board goes up, and the shower floor and walls get a waterproofing membrane. The shower pan is then flood tested: the drain is plugged, the pan is filled and left to sit. TEC and other tile industry sources describe a test of about 24 hours, sometimes up to 48. In an apartment with a neighbor below, this step is not optional.
Tile
Floor and wall tile, niches and any heated floor. Large format tile, intricate patterns and stone take longer. Grout and setting materials need cure time before heavy use.
Fixtures, vanity and glass
Toilet, vanity, faucets, trim, mirror, lights and accessories go in. Custom shower glass is measured after tile is finished, then fabricated, so it often arrives after everything else. Ask about this early.
Punch list
A final walk through, then caulk, paint touch ups, adjustments and cleanup. Block Renovation's figure was about five days for loose ends.
What causes delays
- An incomplete board package. Missing insurance certificates or drawings send you to the back of the line.
- Starting before materials arrive. Block Renovation found that roughly two weeks of its planning period was simply waiting for materials. Everything should be on site or confirmed before demo.
- Hidden conditions. Old galvanized pipe, rotted subfloor, asbestos or lead in older buildings. Our post on prewar apartment renovation in Manhattan covers what to expect.
- Failed inspections. Walls get reopened and the schedule resets for that phase.
- Change orders mid job. Switching tile after the membrane is in, or moving a niche after rough plumbing, costs days.
- Shower glass lead time. The last item on most bathrooms and the most common reason a finished room sits unused.
- Building scheduling. Elevator reservations, water shutoffs and holiday blackouts.
Brick Underground suggests adding one third to any original estimate as a cushion.
Checklist to keep your timeline short
- Finalize every selection, including glass and hardware, before you submit to the board
- Get contractor insurance certificates in the format your managing agent requires
- Confirm the board's meeting date and submission deadline
- Confirm whether your scope needs a DOB filing
- Have all materials delivered or confirmed before demo
- Get a written schedule that fits your alteration agreement window
