    Why Wellesley

    How Wellesley reads on our schedule

    Wellesley is about 16 minutes from our Newton office (437 Newtonville Ave., Suite B, Newton, MA 02460, USA), with 1930s center-entrance colonials with a smaller stock of 1970s contemporaries. We see the most calls from Wellesley Hills, Wellesley Square and Cliff Estates, where housing stock is fairly consistent across blocks and our crews know the inspectors by name.

    What we typically do

    Common scope for Wellesley bathrooms

    Wellesley 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.

    Pricing tiers

    Three tiers for Wellesley bathrooms

    Final price is confirmed in your written Preliminary Proposal after on-site consultation. The tiers below reflect anchor ranges from our calculator (single-family home base, with modifiers for property type and size) or our Preliminary Estimate tier model (whole-home).

    Small bath, single-family

    $30,000

    Anchor base — under 50 sq ft. Property-type and size modifiers below adjust this number.

    Medium bath, single-family

    $33,000

    50 to 100 sq ft. +10 percent size modifier.

    Large bath or condo

    $36,000 – $39,600

    Over 100 sq ft, or a condo with the +10 percent property-type modifier (elevator, HOA, restricted logistics).

    What you sign

    When you sign a Preliminary Proposal with Bay State, the number on the page is the number you build against. See the payment schedule.
