Remodeling a bathroom in Osterville
Osterville is one of the seven villages of Barnstable, on the south side of town along Nantucket Sound, with its center on Main Street, the Wianno shore on East Bay, and Oyster Harbors, a gated community on Grand Island reached over a drawbridge.
Close to the bays and the sound, bathrooms deal with humid, salty air on top of the shower steam. In Osterville we size exhaust fans properly, vent them outside, and choose fixtures and finishes that hold up to it.
In Osterville, as anywhere on the Cape, a bathroom remodel is the time to fix what is behind the walls too: subfloor, framing, venting, and plumbing.
A bathroom remodel in Osterville is permitted by the Town of Barnstable. Most homes are on septic, so a new bathroom that comes with a new bedroom means checking the Title 5 capacity first. In Oyster Harbors, we confirm gate access and work hours before we schedule.

“Mussato Building Group has been a loyal and trusted partner of ours for over ten years and one hundred projects. Their professionalism and quality of work are second to none. We look forward to working with them far into the future.”

Bathroom Remodeling in Osterville: FAQ
Do I need a permit to remodel a bathroom in Osterville?
If the work moves or adds plumbing, gas, or wiring, or changes walls, yes. Licensed plumbers and electricians pull their own permits, and the Barnstable Building Department handles the building permit and inspections. We schedule all of it.
Do you remodel bathrooms in Osterville village and Wianno?
Yes. We remodel bathrooms all over Osterville, including Osterville village, Wianno, and Oyster Harbors. Our base in South Yarmouth is about 12 miles away.
Do you remodel bathrooms in Oyster Harbors?
Yes. Oyster Harbors is part of Osterville, so the Town of Barnstable issues the permits. Because the community is gated, we confirm access and work hours before we schedule.
Can you turn a tub into a walk-in shower?
Yes. We remove the tub, rework the drain and the valve, waterproof the new shower, and tile it.
What do you need from me to give an estimate?
An address, a few photos of the bathroom, and a sense of what you want to change. We set up a visit to measure and give you a free written estimate.
