Bathroom Renovation in NYC, Westchester and Nassau County

A well-built bathroom should look great the day it is finished and still be watertight years later. What you can't see matters most: the waterproofing, the slope of the shower floor, the plumbing behind the wall. Dacaj Construction builds bathrooms the right way from the subfloor up, then finishes them with the tile, stone and fixtures that make the room feel like yours.

We are a family-owned general contractor serving New York City, Westchester County and Nassau County since 2006. We renovate bathrooms in pre-war co-ops, modern condos, brownstones and single-family homes.

Waterproofing Done Right

In an apartment building, a leaking shower doesn't just damage your bathroom. It can damage the ceiling of the unit below and create a costly problem with your neighbors and your board. That is why we treat waterproofing as the most important part of every bathroom we build.

We install proven waterproofing membranes, test shower pans before tile goes down, and slope floors correctly to the drain. Many NYC buildings require specific waterproofing details in the alteration agreement, and we build to those requirements.

Bathrooms in NYC Co-ops and Condos

Most bathroom renovations in NYC buildings need board or management approval. Your building may require drawings, a certificate of insurance, specific waterproofing, and limits on work hours. Many buildings also enforce a wet over dry rule, which restricts moving a bathroom over a neighbor's living space.

We help you understand what your building allows before you commit to a design, and we prepare everything the contractor side of the approval requires.

Our Bathroom Renovation Process

  1. Consultation. We look at your bathroom, discuss your goals and review any building rules that apply.
  2. Selections and proposal. We help you think through tile, fixtures and layout, then provide an itemized proposal and schedule.
  3. Approvals. For apartments, we issue COIs and work through your building's approval process with you.
  4. Construction. Demolition, plumbing, waterproofing, tile and finishes are completed in the right order, with dust control and daily cleanup.
  5. Final walkthrough. We test every fixture and review every detail with you before the job is closed out.

Frequently Asked Questions

How long does a bathroom renovation take?

Most bathroom renovations take a few weeks of construction once materials are on site. Special-order tile or fixtures can affect the schedule, and co-op approvals need to be in place before we start.

How much does a bathroom renovation cost in NYC?

Cost depends on size, whether plumbing moves, the tile and fixtures you choose and building requirements. Our NYC bathroom cost guide explains the main factors, and we provide an itemized proposal after seeing your space.

Can you convert my tub to a walk-in shower?

In most cases, yes. We check the existing drain location, floor structure and building rules, then design a shower that fits the space and drains properly.

Will I have a working bathroom during the renovation?

If you have a second bathroom, you will be able to use it throughout the project. If it is your only bathroom, we will talk through the schedule with you in advance so you can plan.
