Bathroom Renovation Cost Guide for Greater Boston Homeowners

Bathrooms are the second-most popular renovation for Greater Boston homeowners — and they're one of the best investments you can make in your home. Whether you're updating a half bath in Medford or building a spa-worthy master bathroom in Newton, here's what you should budget.

Bathroom Renovation Cost Ranges (2026)

• Cosmetic update ($8K–$15K): New vanity, fixtures, mirror, lighting, and fresh paint. No structural or plumbing changes.

Popular Bathroom Upgrades in Greater Boston

The most requested bathroom renovation upgrades we see from Boston-area homeowners:

• Tub-to-shower conversion: Removing the tub in favor of a spacious, tiled walk-in shower. This is the single most popular request we get.
• Heated floors: Electric radiant floor heating adds comfort and costs $800–$1,500 for a typical bathroom — well worth it in New England winters.
• Frameless glass shower enclosures: A premium look that opens up the space visually. Budget $1,200–$3,000 for supply and install.
• Double vanity: If your bathroom has the space, a double vanity makes a huge quality-of-life difference. Plan $2,000–$5,000 for the vanity, countertop, and plumbing.

Bathroom Permits in Massachusetts

Any bathroom renovation that involves plumbing or electrical work requires permits in Massachusetts. Your contractor should handle all permits and inspections. Unpermitted bathroom work can create problems when you sell your home — inspectors and buyers will flag it.

Frequently Asked Questions

How long does a bathroom renovation take?

A typical full bathroom renovation takes 2–4 weeks of active work. Cosmetic updates can be done in 3–5 days. Custom tile work and walk-in shower builds are the most time-consuming elements.

Can you add a bathroom where there isn't one?

Yes — we regularly add bathrooms in basements, under stairs, and in converted closet spaces. The key requirement is proximity to existing drain lines. The closer you are to existing plumbing, the lower the cost. This pairs well with a basement finishing project.

Does a bathroom remodel add home value?

Bathroom renovations in the Boston area typically recoup 60–70% at resale. More importantly, updated bathrooms significantly reduce time on market — homes with modern bathrooms sell faster in competitive markets like Brookline and Quincy.
