Bathroom remodeling in Waltham,including the unit upstairs.
Waltham is a landlord's town as much as a homeowner's town, and that changes how a bathroom gets built. A second-floor bath over an occupied unit is not a place to take chances with a shower pan — one bad membrane and the problem shows up on your tenant's ceiling and your insurance.

What a Waltham bathroom throws at a crew.
The Watch City housing stock is a mix: two-families and triple-deckers around Moody Street and the Bleachery, 1920s and 1930s colonials up in the Highlands and out toward Warrendale, and mid-century ranches and capes off Lexington Street. Different eras, same two questions — where does the waste stack run, and what is under the tile.
We flood-test every pan for 24 hours before tile, and we tell you which days the water is off so a tenant is not finding out at 7 AM. If the bath serves a rental, downtime is money, and we schedule it that way.
- Baths over occupied units
- Sloped mortar bed, bonded membrane, banded corners and a 24-hour flood test before a single tile goes down.
- Shared waste stacks
- In a two- or three-family the stack is common property. We plan the tie-in and the water-off window around both units.
- 1920s colonial hall baths
- Plaster and lath, hex-tile floors and a single bath for the whole floor — the classic full-gut candidate.
What we run into here
What it costs you in days
Seven working days in Waltham.
The sequence doesn't change from town to town — only what we find behind the plaster does.
- 01Day 1
Protection and demo
Dust wall up, room stripped to the studs, debris out the same day. This is also when surprises surface, and when we tell you about them.
- 02Day 2
Rough plumbing and electrical
New drain and supply, valve set, GFCI and lighting, fan ducted outside. Permits pulled with your town and inspections scheduled by us.
- 03Day 3
Waterproofing
Mortar bed, membrane, banded corners, flood test. This is the day that decides whether the ceiling below stays dry for twenty years.
- 04Day 4
Tile and grout
Dry layout first so the cuts are deliberate. Then wall, floor, niche, grout, and silicone at every corner and change of plane.
- 05Day 5
Vanity, fixtures and trim
Everything you actually touch goes in: vanity, top, faucet, toilet, mirror, lighting, hardware, door and trim.
- 06Day 6
Walk-through and sign-off
We walk the room with you, write the punch list, finish it, and clean the space before we invoice.

on Angi
“I hired 7 Days Remodel & Contracting to replace my deck and repair the front porch. I also needed new kitchen and bathroom flooring and tile on the kitchen counter and upstairs bathroom. Al and his team were extremely professional and multitasked to complete interior and exterior while I was away on military orders. Pleasantly surprised and extremely satisfied with the outcome and highly recommend them — Al communicated consistently throughout the process and completed the work as discussed prior to my return and on budget.”
“Al did a great job on our renovation of our three-unit apartment building. He showed up, his team showed up, and everyone was skilled, delivering a great result.”

“The job was done in a timeframe that was shorter than projected. Their team was very professional and did a great job cleaning up behind themselves.”

Straight answers
Bathroom questions we get in Waltham.
How long does a bathroom remodel take?
A standard full bath runs about seven working days on site, plus the shower glass, which is templated after the tile is grouted and installed when the fabricator delivers. Layout changes, custom tile patterns and long-lead vanities push that out — and we put the real number in your written proposal instead of the optimistic one.
Can we still use the bathroom while you work?
Not the one we're building. If it's your only full bath, tell us at the estimate — we sequence the toilet back in as early as the work allows and we'll tell you honestly which nights you'll want a plan B.
Do you pull the permits?
Yes. Plumbing and electrical permits are pulled with your town's building department and we schedule the inspections. You don't chase paperwork.
What does a bathroom remodel cost?
It depends on the size of the room, whether the layout moves, and what you pick for tile, vanity, fixtures and glass. We don't quote bathrooms over the phone. The on-site estimate is free, takes about thirty minutes, and produces a written itemized price within 48 hours.
Can you convert a tub into a walk-in shower?
Yes, and it's one of the most common jobs we do in older Greater Boston homes. It usually means a new pan and drain location, a proper sloped mortar bed and membrane, and a decision about whether to keep a curb or go curbless — which depends on your joists. We look at that at the estimate.
Do you do small bathrooms and powder rooms?
Yes. A 5×7 second-floor bath in a 1920s two-family is our bread and butter, and a powder room is a short job we're happy to schedule.
What about asbestos or lead paint?
We don't do asbestos abatement or de-leading — those need a licensed specialist and we'll refer you to one. If we find something behind the wall during demo, we stop, tell you, and don't disturb it.
Who is actually in my house?
Our own vetted, certified crew. Same faces from demo day to the final walk-through, and you have Alessandro's number the entire time.
