Charlestown is about 6 minutes from our Boston office (121B Tremont St., Suite 24, Boston, MA 02135, USA), with Federal-era rowhouses, brick triple-deckers, and a smaller stock of post-war townhouses. We see the most calls from Bunker Hill, Town Hill and Navy Yard, where housing stock is fairly consistent across blocks and our crews know the inspectors by name.
Charlestown bathrooms come to us most often as primary or guest baths in a 1900s to 1950s footprint where the original cast-iron stack and a single-pane window are both due to be retired. The first 30 minutes on site are spent measuring the rough-in, photographing the joist direction below the floor, and confirming whether we are keeping the existing layout or moving the toilet.
Every wet area is detailed with Schluter-Kerdi waterproofing — the membrane goes on the substrate before tile, the curb gets pre-formed Kerdi corners, and the niche is built from Kerdi board so the entire shower envelope is watertight before the first piece of tile lands. We flood-test before tile on every job.
Construction runs 40 to 45 business days on site once permits clear, including a 5 to 10 day rough-inspection waiting period. Glazing and mirrors are fabricated only after tile is set and arrive last; they will not delay bathroom use upon main construction completion.

$33,000
50 to 100 sq ft. +10 percent size modifier.
$36,000 – $39,600
Over 100 sq ft, or a condo with the +10 percent property-type modifier (elevator, HOA, restricted logistics).
When you sign a Preliminary Proposal with Bay State, the number on the page is the number you build against. See the payment schedule.
Most of Charlestown sits inside the Charlestown Historic District. Exterior changes need Boston Landmarks Commission review, which adds 4 to 8 weeks to the schedule. Interior-only kitchen and bath permits clear through Boston ISD in 2 to 4 weeks.
Bay State handles all permit applications and inspections. Copies of approved permits are provided to every client. See how the project flows.
