A bathroom remodel in Cambridge can range from a tub-to-shower conversion and new vanity to a full gut that moves plumbing, rebuilds the wet wall, and reworks a tight floor plan. In the city's older homes and condos, the real work is often hidden: waterproofing, ventilation, and replacing aging supply and drain lines.
Cambridge bathrooms are frequently small, stacked between floors in two- and three-family homes, and served by original cast-iron or galvanized plumbing. Fitting a modern layout into a compact footprint, and protecting the framing and the unit below from moisture, is the core of a good remodel here.
A typical JRH bathroom remodel in Cambridge includes:
Full waterproofing behind tile, with proper substrate and a code-compliant shower pan.
New supply and drain lines to replace old cast-iron and galvanized plumbing.
An exhaust fan vented to the exterior to control moisture in tight, interior baths.
Vanity, tile, and fixture layouts planned for compact Cambridge footprints.
It is worth doing when your bathroom leaks, lacks ventilation, or no longer suits how your household uses the space.
The process starts with a free in-home consultation and measurements in your Cambridge bathroom, followed by an itemized written estimate and scope that includes permit handling and waterproofing details.
After you approve the design and finishes, JRH files for permits through the City of Cambridge Inspectional Services Department, and a licensed plumber and electrician pull their own permits as Massachusetts requires.
We then demolish, correct any hidden water damage, rough in new plumbing and wiring, waterproof, tile, and set fixtures, closing with inspections and a final walkthrough. Timelines depend on scope and whether plumbing moves.
Yes. The City of Cambridge Inspectional Services Department (ISD) requires a building permit for bathroom remodeling in nearly every case, with painting, tiling, and flooring as the only interior exceptions. Plumbing and electrical changes require separate permits pulled by licensed trades.
Because a bathroom is a wet area over occupied space, and many Cambridge baths sit above a downstairs unit, code covers waterproofing, exhaust ventilation, and fixture clearances. Getting these inspected is what protects the framing and the ceiling below from long-term water damage.
JRH manages the permit process through the city's online permitting portal, so your bathroom stays inspected and code compliant. Cambridge ISD is located at 831 Massachusetts Avenue and can be reached at (617) 349-6100.
Skipping permits on a bath is a gamble: hidden leaks and failed waterproofing tend to show up years later during a sale, or as damage to the unit below, and cost far more to fix than to do correctly the first time.
Across Massachusetts, bathroom remodels commonly run from about $3,700 for a light update to $80,000 or more for a large, high-end bath, averaging near $17,600, with most projects landing between about $8,800 and $25,000 (fixr, MA, 2025-2026 data). Small footprints push the per square foot number high, near $440 on a compact bath.
Some upgrades qualify for statewide incentives. Mass Save offers rebates for heat pumps, insulation, and efficient equipment added during a renovation.
