Bathroom Remodeling in Brooklyn, Manhattan, Queens & Staten Island

Bathrooms are small rooms with zero margin for error. We rebuild them with proper waterproofing, clean tile work, and fixtures that last — handled start to finish by our own crews.

A bathroom renovation looks simple until you open the walls. Old galvanized plumbing, undersized vents, rotted subfloors, and decades of patchwork tile are the norm in New York City apartments and houses. M&M GC Contractor Inc has been gutting and rebuilding bathrooms across Brooklyn, Manhattan, Queens, and Staten Island since 2001, and we treat waterproofing as the job — not an afterthought.

From hall bathrooms in Bay Ridge co-ops to primary suites in Staten Island homes and spa-style retreats in Manhattan condos, we deliver bathrooms that look sharp and stay dry for decades.

Waterproofing done right the first time

Most bathroom failures start behind the tile. We strip bathrooms to the studs, replace old supply and waste lines, install proper cement board and waterproofing membranes in every wet area, and flood-test shower pans before a single tile goes up. That discipline is why our bathrooms don't leak into the apartment below — the nightmare scenario every NYC homeowner fears.

Then comes the part you see: large-format tile, curbless or curbed showers, new vanities, modern fixtures, proper ventilation, and layered lighting. Clean lines, tight grout joints, and finishes that are easy to maintain.

Built for NYC buildings and their rules

Bathroom work in co-ops and condos means alteration agreements, licensed plumbers and electricians on the insurance certificates, and strict work hours. We prepare board packages regularly and our plumbers and electricians are in-house and licensed, so approvals go smoothly.

In houses across Staten Island and Brooklyn, we handle the full scope too: stack replacements, venting corrections, and subfloor rebuilds that older homes almost always need once the old tub comes out.

Why homeowners and businesses choose M&M

  • Licensed & insured general contractor operating in New York City since 2001 — over two decades of finished jobs, not promises.

  • In-house crews for demolition, framing, drywall, flooring, electrical and plumbing — fewer subcontractors, fewer delays, one accountable team.
  • NYC building know-how: DOB permits, co-op and condo board packages, Landmarks Preservation Commission approvals, occupied-building logistics — we've done it hundreds of times.
  • Direct line to the owner. Call (917) 251-9318 and you talk to the people actually running your job.

How your project runs, start to finish

  1. Consultation & site visit. We walk the space, listen to what you want, and flag anything structural, code-related, or permit-related up front.
  2. Detailed scope & estimate. You get a clear written scope and a firm price — no allowances hiding the real number, no surprise change orders later.
  3. Construction. Our in-house crews handle demolition through final finishes. The site stays clean, protected, and on schedule, with one point of contact throughout.
  4. Final walkthrough. We go through every detail together before sign-off. If something isn't right, we fix it. That's the "built on trust since 2001" part.

Common questions

How long does a bathroom remodel take?
Most full bathroom gut renovations take 3 to 5 weeks of construction. If plumbing stacks need replacing or the board approval process is involved, we build that into the schedule up front.
Can you move the toilet or shower to a different spot?
Usually yes, though it depends on the waste line layout and building rules. We'll assess feasibility during the site visit and give you an honest answer before you commit.
What's the biggest cost driver in a bathroom renovation?
Plumbing relocation and the extent of tile work. Keeping fixtures roughly where they are keeps costs down; moving waste lines adds labor and material. We'll price both options so you can decide.
