Bathroom remodeling in the Bronx, apartment or house

We remodel bathrooms across the Bronx, from co-op and condo apartments in large buildings to one- and two-family houses in Throgs Neck, Pelham Bay, City Island and Riverdale. Most Bronx homes are in buildings of 20 or more units, so we first establish whose rules govern the room: the building's or the house's.

  • Apartment bathrooms scheduled to the building's alteration agreement
  • House bathrooms, with DOB filings where the plumbing work needs them
  • Flood-map checks before a ground-floor bath in the east Bronx

Scope

Bronx bathroom work we take on

Every Bronx bathroom gets a written scope after a site visit, with the building's or the property's constraints listed beside the work they affect.

  • Apartment bathroom renovations in co-op and condo buildings, after board approval
  • Fixture-for-fixture replacement where a building limits plumbing moves
  • Tub replacement and shower conversions in house bathrooms
  • Floor waterproofing and drain details that protect the home below
  • Exhaust fan replacement and controls matched to the room size
  • Grab bars, step-in showers and shower seating for aging in place

Process

How MMA Construction & Remodeling runs a bathroom remodeling project

Written scope, written proposal, permits identified up front, and one project lead from start to finish.

  1. Conversation

    You describe the home and what you want to change. We ask about budget range and timing so expectations are clear early.

  2. Site visit and scope

    We look at the space, the structure of the house and any HOA, co-op or condo rules that apply, then write a scope of work.

  3. Design and selections

    Layout, materials and fixtures are agreed in writing before work is priced in full.

  4. Written proposal

    A written price and schedule for the agreed scope. Permits and any approvals are identified at this stage.

  5. Build

    One project lead coordinates the trades and keeps you updated. Some regulated work may require appropriately licensed specialty contractors.

  6. Walkthrough

    We review the finished work with you and resolve anything outstanding.

The Bronx

Bronx bathroom decisions by building type

  1. In a large building, the board sets the terms

    Around 61% of the borough's homes sit in buildings of 20 units or more. For an apartment, the alteration agreement usually governs working hours, the building's insurance requirements and approvals, and some buildings will not allow a toilet or shower to move over a neighbor's bedroom. We read the agreement first, design a bathroom that fits inside it, and prepare the scope description and drawings list that the managing agent asks for before review.

  2. Risers, shutoffs and the apartment below

    An apartment bathroom normally ties into vertical supply and drain risers that serve the units above and below it. Shutting a riser affects the neighbors, so many buildings control when it can happen and who operates the valves. Here the shower pan, the drain connection and the floor membrane carry more weight than usual, because a leak ends up in another family's home. We confirm the riser rules with the super or managing agent before anything is removed.

  3. East Bronx houses and shoreline flooding

    Roughly 69% of Throgs Neck-Schuylerville homes are one- or two-family, and about 60% predate 1960. City Planning reported in 2017 that Community District 10, which includes Throgs Neck, held nearly 80% of the Bronx's floodplain buildings. Before a basement or ground-floor bathroom is planned there, check the address on the FEMA and city flood maps. In Edgewater Park, a cooperative board sets architectural and construction guidelines, so ask for them early.

  4. Riverdale and City Island houses

    Riverdale counts mostly as large buildings when you tally units, yet most of its tax lots hold houses, so a Riverdale bathroom can follow either the apartment path or the house path. On City Island, roughly two-thirds of the housing units in the island's census tract were built in 1939 or earlier, and FEMA's 2015 preliminary map flags about a third of its residential lots. Old plumbing and a flood check both belong in a City Island bathroom brief.

Ready to scope a Bronx bathroom?

If you live in a co-op or condo, send the alteration agreement with your photos; if it is a house, tell us the neighborhood and the floor. We will set up a site visit and write the scope.

Local evidence

What Bronx records say about bathroom projects

Bronx figures that decide which kind of bathroom job you have (ACS and city lot data, as cited in our sources)
PlaceFigureBathroom consequence
Bronx boroughabout 61% of units in buildings of 20+ unitsBoard rules and shared risers come first
Throgs Neck-Schuylerville68.9% of units in one- or two-family buildingsHouse bathrooms with older pipes
Riverdale-Spuyten Duyvil2,022 of 3,054 lots with a one- or two-family classEither an apartment or a house job
City Island (tract 516.01)1,474 of 2,191 housing units date from 1939 or earlierPre-war plumbing is likely
City Island (tract 516.01)375 of 1,198 residential lots on FEMA's 2015 mapFlood check before a ground-floor bath

From Spuyten Duyvil to City Island, permits for a Bronx home are a matter for the city's Department of Buildings. DOB's own examples of work needing no permit include painting, new cabinets and floor resurfacing, while a more involved bathroom can require an engineer or architect to file plans. Plumbing work in the city belongs to a Licensed Master Plumber, and home improvement contractors working here hold a city DCWP license.

Around 76% of Bronx homes are in pre-1980 buildings. Under EPA rules, paid work disturbing paint in a home built before 1978 must follow lead-safe practices, so we open painted walls and ceilings in an older Bronx bathroom with containment and careful cleanup.

The Landmarks Preservation Commission lists 13 Bronx historic districts and designates individual landmarks on top of those. Use LPC's Discover NYC Landmarks map for the address before planning a new exhaust outlet or a different bathroom window. The Riverdale page covers the districts there, and the Throggs Neck page covers the cooperative land communities.

Questions

Bathroom remodeling in the Bronx: questions

Can I move the shower or toilet in my Bronx co-op apartment?
Sometimes, but the building decides first. Many co-op and condo buildings restrict relocating wet areas, especially over a neighbor's living space, and moving a fixture changes the connection to shared risers. Where the building allows it, the work requires a Licensed Master Plumber, and the scope may need a DOB filing prepared by a licensed engineer or architect. We review the alteration agreement and the riser locations before we draw a new layout.
Who deals with the super and the managing agent during a Bronx apartment bathroom job?
Our project lead does. That covers booking the service elevator, scheduling riser shutoffs with the super, keeping to the permitted working hours, protecting hallways and removing debris at the times the building sets. Notices to neighbors go out through the channel the building prefers. You stay informed, but you are not the one coordinating the trades and building staff on any given day.
Does a house in Edgewater Park need the co-op board's approval for a bathroom remodel?
Ask the board before you plan. According to a 2015 City Planning study, Edgewater Park homeowners own their houses while leasing the land through shares, and a 15-member board sets architectural and construction guidelines. We request those guidelines at the start, plan the bathroom to fit them, and handle any city filings the scope needs as a separate step. The Throggs Neck page explains the cooperative land communities in more detail.
Is a walk-in shower practical for an older relative in a Bronx apartment?
Often, with limits. A fully curbless entry depends on whether the floor can be recessed for drainage, which a concrete slab in an apartment building may not allow; a low curb is the usual alternative. The CDC's home safety checklist suggests grab bars inside the tub or shower and next to the toilet for people who need support, plus non-slip surfaces. ADA standards do not cover the residential portions of a private home, so these are choices for your household.
