What a Bathroom Remodel Costs in Greater Boston, and the Five Things That Move the Number

Everyone asks for a number before the walk-through, and every honest contractor says the same thing: it depends. Here is what it depends on, so you can set a budget that will actually hold.

The honest range

For a standard full bath in the Boston area in 2026, most homeowners spend somewhere between the low twenties and the high forties for a full gut and rebuild, and more if the layout moves or the finishes are high end. A tub-to-shower conversion or a cosmetic refresh (new vanity, tile, fixtures, paint, same layout) can come in well under that. We give a real number after we see the room, never from photos, because the five things below are not visible in a photo.

1. Whether anything moves

Keeping the toilet, sink, and shower where they are is the single biggest cost saver. Moving a drain line in an older Boston house often means opening the ceiling below, and in a condo it means involving the unit downstairs.

2. What is behind the walls

Triple-deckers and pre-war homes hide galvanized pipe, knob-and-tube wiring, and framing that was never square. Any of those add work once the tile comes off. A good estimate carries an allowance for it and tells you what that allowance covers.

3. Tile and finishes

Tile labor is priced by the square foot and by complexity. Large-format porcelain on a flat wall is fast. Small mosaic, herringbone, or a niche with mitered edges takes days longer. The material itself ranges from a few dollars a square foot to forty.

4. The shower system

A prefab base and surround installs in a day. A custom tiled shower with a linear drain and a glass enclosure is a week of work and the enclosure alone can be several thousand. Both are good choices; they are just different budgets.

5. Permits and code

Bathroom work in Boston, Quincy, Brookline, and most surrounding towns needs a building permit plus electrical and plumbing permits. Code requires GFCI outlets, proper venting, and in some cases updated supply lines. It is not optional and it should be in the estimate.

How to keep the number down without regretting it

• Keep the layout.
• Spend on the shower and the vanity, the two things you touch daily. Save on the accessories.
• Pick everything before demo starts. Mid-build changes are where budgets die.
• Get a line-item estimate, not a lump sum, so you can see where the money goes.
