Bathroom remodel in New York City, done the right way
A bathroom remodel in New York City runs into a set of constraints that mostly do not exist in a single-family suburban house — a building that may be older than the plumbing code itself, a board that has to approve the work before it starts, a room the size of a large closet, and a crew that has to get materials up four or five flights before anyone can start demo. None of that is a reason to skip a remodel. It is a reason to plan for it honestly before you sign anything.
Pre-war buildings and old cast-iron stacks
A meaningful share of New York's housing stock predates modern plumbing standards, and many buildings still run on original cast-iron waste stacks shared by every apartment stacked above and below yours. Cast iron lasts a long time, but it corrodes from the inside in ways that are invisible until a leak or backup forces the issue, and because the stack is shared, work on it can affect neighbors above or below, not just your own unit.
Before any bathroom remodel in a pre-war building, ask specifically whether the stack itself is being inspected or touched, and understand that a contractor working on a shared stack may need building engineer sign-off or coordination with the super, separate from your own board approval.

Co-op and condo board approval is a real gating factor
This is the step homeowners underestimate most. In a co-op or condo, a bathroom remodel almost always requires board approval and a signed alteration agreement before work can begin — and that process can take weeks, sometimes longer, depending on the building and the season. Boards commonly require proof of contractor insurance, a certificate of insurance naming the building, defined work hours, and sometimes a security deposit held against damage to common elements.
Start the board application in parallel with getting quotes, not after you have already picked a contractor and a start date. A contractor experienced with New York buildings will already know this rhythm and can usually provide the paperwork a board asks for without much back-and-forth. One who has never dealt with a board before is a real scheduling risk, independent of the quality of their tile work.
Small footprints where every inch is fought over
Many New York City bathrooms, especially in older buildings, are genuinely small — sometimes barely large enough for a tub, a toilet and a pedestal sink with room to turn around. In a space that tight, layout decisions that would be minor elsewhere become the difference between a room that works and one that never quite does: door swing direction, whether a vanity has any storage at all, and whether a tub-to-shower conversion actually gains usable floor space or just moves the constraint around.
In a small New York bathroom, it is worth spending real planning time on the layout before any decision about tile or fixtures, because there is so little room to correct a bad call once the plumbing is set.
Walk-ups, freight elevators, and what that does to cost and timeline
A large number of New York City apartments sit in walk-up buildings with no elevator at all, and many buildings that do have elevators reserve a freight elevator, on a scheduled booking, for contractor material and debris. Either situation adds real labor time and real scheduling friction that a suburban house never has to account for — every tile, every bag of thinset, every old fixture removed has to move by hand up stairs or through a booked freight window.
Ask directly how a contractor accounts for building access in their quote and their timeline, and whether they have worked in a walk-up or freight-elevator building before. This is not a minor logistics detail here — it genuinely changes both the labor cost and how realistic the proposed schedule is.
Wet walls and stack location limit what can move
In many New York buildings, the plumbing wet wall and the stack location are fixed by the building's original construction and shared with the apartments around you, which limits how freely a layout can change compared to a house where you own the whole plumbing run. Moving a drain or a stack connection in this kind of building is a bigger undertaking than the same move in a single-family home, and it may also require board and engineer sign-off beyond your own apartment.
Ask early whether your plan requires moving anything connected to the shared stack, since that answer shapes both the cost and whether the board approval process gets more involved.

Common questions
Do I really need board approval for a bathroom remodel?
In almost every co-op or condo, yes. Boards typically require a signed alteration agreement, proof of contractor insurance naming the building, and defined work hours before any work can start. Start this process early — it commonly takes weeks.
Why does a contractor need to know if my building has a freight elevator?
Material and debris access in a walk-up or freight-elevator-only building takes real extra time and has to be scheduled, and that affects both labor cost and the realistic timeline. A contractor unfamiliar with this kind of building may underquote it.
Can I move my tub-to-shower drain in an older apartment building?
Sometimes, but it depends on the wet wall and stack layout, which in many buildings is shared and fixed by the original construction. Ask early whether your plan touches anything connected to the shared stack, since that can add cost and require board or engineer sign-off.
