Finding the right bathroom remodeling company in New York City means balancing design, building code compliance, and the realities of co-op and condo approvals. This guide helps homeowners across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island compare top firms, understand permits and DOB requirements, and pick materials that stand up to humid subway summers and salt‑air winters near the Harbor.
Top 5 Roofing Companies in New York City
Although focused on bathroom remodels, many general contractors in NYC also handle bathroom‑to‑roof flashing, venting and waterproofing—critical for multi‑story brownstones and high‑rise units near landmarks like Central Park and the East River. Here are five reputable local companies known for bathroom renovations and roof‑to‑bath coordination.
Manhattan Bath Co.
Manhattan Bath Co. specializes in high‑end bathroom renovations for co‑ops and brownstones in neighborhoods such as the Upper East Side, Tribeca, and Greenwich Village. The firm emphasizes historic‑sensitive work — matching tile and plaster profiles — and coordinates DOB filings when modifications affect roof vents or exterior walls.
Pro tip: Manhattan Bath Co. often assists with co‑op board packages and energy code compliance for ventilation upgrades. Their teams include licensed plumbers and certified waterproofing installers to reduce leak risks to units below.
Brooklyn Bath Works
Brooklyn Bath Works serves Brooklyn neighborhoods from Park Slope to Williamsburg, offering modern and budget‑wise options. The company is known for efficient demo-to-finish schedules in rowhouses and for handling asbestos testing and abatement in pre‑1950 buildings when necessary.
Here’s why clients pick them: they coordinate scaffolding, protect common areas, and secure DOB permits when roof penetrations or new exhaust ducts are required, reducing delays during co‑op approval processes.
NYC Remodel Pros
NYC Remodel Pros is a full‑service contractor focused on mid‑range to luxury bathrooms across all five boroughs. They provide 3D designs, material sourcing, and manage intersections between plumbing stacks and rooftop vents—critical for avoiding shared‑stack service interruptions in multi‑unit buildings.
They also have experience with landmarked properties and know when Landmarks Preservation Commission approval is needed for visible exterior changes or rooftop equipment related to bathroom ventilation.
Upper East Bath & Tile
Upper East Bath & Tile specializes in tile work, custom vanities, and wet room conversions for condos and boutique rentals near museums and shopping corridors. The company emphasizes water‑tight installations and uses manufacturer‑backed systems for showers and steam rooms to protect units below.
Pro tip: Upper East Bath & Tile offers warranty packages that cover tile delamination and grout failure, and they often work with building superintendents to schedule work during off‑peak hours in busy elevator‑served buildings.
Five Boroughs Bath
Five Boroughs Bath operates citywide and focuses on timely small to medium projects, ideal for landlords renovating units for rent or resale. They handle quick tile‑to‑toilet turnovers and inventory management for common fixtures like low‑flow toilets compliant with NYC water conservation rules.
They coordinate with insurance carriers for water‑damage claims, and their teams are versed in filing DOB work permits for plumbing and minor structural work affecting roofs and exterior penetrations.
How to Choose a Bathroom Remodeling Company in NYC
Choosing the right contractor requires matching skills to the building type. Here’s a practical checklist: license verification, DOB filing experience, co‑op/condo board references, insurance and general liability limits, and examples of similar projects in your neighborhood.
Here’s why credentials matter: older Manhattan brownstones often require careful roof flashing and historic‑style vents, while newer condominiums demand coordination with building management for stack shutoffs and elevator access. Ask for a certificate of insurance and copies of permits from past jobs.
Permits, Codes, and Co‑op Approvals
Permits in NYC are not optional. Plumbing, structural changes, and new roof vents require DOB permits and sometimes filings with the Department of Environmental Protection. Contractors should know when an Alteration Type 1, 2, or 3 filing is required and how to prepare drawings for plan exam.
Co‑op boards and condo management often require contractor insurance, DOB permit copies, and a proposed work schedule. Landmarked buildings need LPC approval for any exterior work, including rooftop exhausts visible from the street. Pro tip: get approvals in writing before demolition to avoid costly pauses.
Materials, Costs, and What Fits Your NYC Home
Material choices affect durability and cost. Asphalt shingles don’t apply for most NYC bathrooms, but waterproofing systems, tile types, and vanity materials do. Below is a concise comparison to guide decisions for typical NYC projects.
| Material/System | Typical Cost Range | Best For |
|---|---|---|
| Ceramic/Porcelain Tile | $8–$25 per sq ft installed | Wet areas, subway tile backsplashes, durable high-traffic floors |
| Natural Stone (marble/granite) | $20–$60+ per sq ft installed | Luxury finishes; requires sealing, heavier load considerations on old joists |
| Waterproof Membrane Systems | $10–$30 per sq ft installed | Showers, steam rooms, wet-room conversions; essential to protect units below |
| Prefabricated Shower Pans | $300–$1,200 installed | Quick installs in rentals; less customizable than tiled drains |
| Engineered Vanity/Countertops | $500–$3,500+ | Moisture-resistant, wide style choices, fits small NYC footprints |
Typical Project Timeline and Phases
Timelines vary by scope: small cosmetic updates (fixtures, tile refresh) often take 1–2 weeks; full gut remodels in multi‑unit buildings typically run 6–10 weeks, plus permit wait time. Here’s a breakdown:
- Pre‑construction and permits: 1–4 weeks (longer with co‑op/landmark approvals)
- Demolition and rough‑in plumbing/electrical: 1–2 weeks
- Waterproofing and subfloor work: 3–7 days
- Tile, fixtures, finishes and inspections: 2–4 weeks
Waterproofing, Roof Venting, and Preventing Leaks
Bathrooms above other units require rigorous waterproofing and correct venting. Contractors should install manufacturer‑approved membranes and ensure roof exhausts and vent stacks are flashed and sealed to prevent leaks that travel from roof through bathroom walls.
Here’s why this matters: improperly flashed rooftop vents or compromised parapet areas near HVAC units can channel water into bathrooms below. Request written waterproofing warranties and confirm that roof penetrations were coordinated with the building’s roofing contractor if work reaches the roofline.
Insurance Claims and Working with Carriers
If a remodel follows water damage or an insurance claim, contractors should provide detailed scopes, itemized estimates, and photographic documentation. Insurers often require licensed plumber invoices and permit copies before releasing full payouts for repairs that involve roof or vent work.
Pro tip: choose a contractor experienced in documenting damages for carriers and able to provide repair options that meet insurer expectations and DOB requirements simultaneously.
Questions to Ask Before Signing a Contract
- Will the company pull all required DOB permits and handle plan exam filings?
- Do they have experience with co‑op board and LPC approvals for your neighborhood?
- Who is the on‑site project manager and what is the communication protocol?
- Are waterproofing and venting warranties provided in writing?
- How will they protect common areas, elevators, and neighboring units during demo?
Frequently Asked Questions
How long does a full bathroom gut remodel take in NYC?
Full gut remodels typically take 6–10 weeks after permits are approved; timeline increases with co‑op/landmark approvals or complex roof/venting work requiring coordination with building management.
Do bathroom remodels require DOB permits?
Yes. Plumbing and structural modifications almost always require DOB filings. Installing or modifying exhaust vents that penetrate the roof also typically needs permits and, in some cases, plan exam approval.
How to handle co‑op board approval?
Provide the co‑op a contractor insurance certificate, DOB permit copies, a detailed work schedule, and references. Many boards also require contractors to coordinate elevator use, noise windows, and debris removal protocols.
What warranty should be expected?
Look for at least a one‑year contractor warranty on labor and longer manufacturer warranties on fixtures and waterproofing systems. Ensure warranty terms are written into the contract.
Can remodels affect rooftop work or require roofing contractors?
Yes. New exhaust fans, vent stacks, or rooftop flashings may require roofers to reseal penetrations. Coordinating with a roofing contractor avoids leaks and ensures compliance with building envelope standards.
Next Steps
Request written estimates from at least three of the companies above, verify licenses and recent DOB permit history, and ask for a detailed project schedule that includes co‑op or condo board milestones. With the right contractor, homeowners can achieve a durable, stylish bathroom that stands up to New York City’s climate and building complexities.
