Bathroom Remodeling Contractor in Greater Boston, MA

Bathrooms planned from the studs out.

Primary baths and larger bathroom remodels, from the plumbing and waterproofing to the tile and the vanity.

Waterproofing and venting

What goes behind the tile

Water and steam wear a bathroom out from behind the walls. We plan the waterproofing and the exhaust fan as carefully as the vanity you’ll see every day.

  • Supply and drain lines to code, inspected while the walls are open
  • Blocking in the walls for grab bars, glass and the vanity

Curbless showers and freestanding tubs

The floor is what makes a curbless shower work

With no curb to hold the water in, the shower floor has to sit lower than the rest of the room and slope to the drain. That means recessing it into the framing, or raising the rest of the bathroom floor. A freestanding tub needs its drain in the right spot and a floor strong enough to hold it full of water. We work out both with the designer early on.

Bathrooms in older houses

What opening an older bathroom can turn up

  • Galvanized or cast iron pipe
  • Venting too small for the room
  • Old wiring behind the walls
  • Paint from before 1978

In a house built before 1978, any work that disturbs painted surfaces has to follow lead‑safe practices. We write into the scope what happens if any of these turn up.

How long will we be without the bathroom?

It depends on the scope. Before work starts, we give you a schedule that shows the day the bathroom goes out of service and the day it’s back.

How are the permits filed in my town?

We handle them, and in most towns around here that’s online now. Needham doesn’t accept paper applications at all. Newton uses its NewGov portal and Wellesley uses ViewPoint Cloud. Hopkinton moved residential building, plumbing and electrical permits online on September 1, 2026.

Can a bathroom go where there isn’t one now?

Usually, as long as a drain and a vent can reach it. For a new bathroom upstairs or in the basement, we work out where those lines can run, and design the room around them.

What does a bathroom remodel cost?

It depends on the size, what’s behind the walls and the finish level you choose. Once the design is done, you get a written price that lists the tile, fixtures and vanity.
