A full bathroom renovation means taking the room to the studs, replacing what’s behind the walls, then rebuilding it. US ProPaint and Renovation handles these across Weymouth from our Hingham shop. Most standard bathrooms take three to five weeks from demolition to final walkthrough.

A bathroom is the most complicated room in a house per square foot. Plumbing supply and drainage, electrical, ventilation, waterproofing and finish carpentry all stack into forty square feet, and every one of them has to be right before the tile goes on. Here’s the actual sequence, and what tends to go sideways.
1. Consultation and written scope. We walk the room with you, talk through layout, and write a scope with fixture allowances. Free. This is also where we tell you honestly whether you need a full renovation or something smaller — sometimes the answer is refinishing the tub and tile for a fraction of the cost.
2. Design and selections. Layout, tile, vanity, fixtures, lighting. Making these decisions before demolition starts is the single biggest factor in whether a project finishes on schedule. Mid-project selection changes are what turn a three-week bathroom into a seven-week one.
3. Permits. Building, plumbing and electrical permits through the Town of Weymouth. We pull them.
4. Demolition. Tile, fixtures, vanity, flooring and usually the wall substrate come out. On a small bathroom this is a day; on a master with a tiled shower, two.
5. Rough-in — plumbing, electrical, ventilation. Licensed trades. New supply and drain lines, dedicated circuits and GFCI protection to current code, and an exhaust fan vented to the outside rather than into the attic, which is one of the most common defects we find in older Weymouth homes.
6. Inspection, then substrate and waterproofing. Rough inspections have to pass before anything closes up. Then cement board, and a proper waterproofing membrane behind the shower surround. This stage is invisible in the finished room and it’s the one that determines whether you’re doing this again in twelve years.
7. Tile, fixtures, vanity, finish carpentry. Floor and wall tile, shower glass, vanity and countertop, toilet, trim, and paint through our own interior painting crew.
8. Final inspection and walkthrough. Town sign-off, then we walk the room with you before calling it done. Our work carries a 5-year warranty.
Roughly 30% of bathroom remodels uncover hidden problems once demolition starts, and in our experience on the South Shore that number feels low. Bathrooms are wet rooms in houses that are mostly forty to eighty years old. Four things turn up repeatedly:
Mold behind the shower surround. The most common, and the most consequential. A shower that’s been leaking slowly through failed grout or a missing membrane will have been feeding mold inside the wall cavity for years before anything shows on the surface.
Rotted subfloor around the toilet flange. A slow wax-ring leak destroys subfloor quietly. You usually find it by feel — a soft spot — long before you’d see it.
Old plumbing that can’t be reused. Galvanized supply lines, undersized drains, and vent stacks that were never right. If we’re opening the wall anyway, replacing these costs a fraction of doing it later.
Ventilation that goes nowhere. Fans vented into the attic or into a soffit, pumping moist air into the roof structure. We see this constantly.
Here’s where we differ from most remodelers: if we find mold, we don’t stop the job and send you to find a third party. US ProPaint holds both a Certified Residential Mold Inspector licence (CRMI0000036883) and a Certified Mold Remediator licence (CMR0000036885), so we can inspect, remediate and rebuild under one contract. For a homeowner that’s the difference between a two-day detour and a three-week stall while you find a remediation company, get them scheduled, and then get your contractor back. If the moisture has travelled further than the bathroom, our water damage crew handles that too.
Most bathroom contractors on the South Shore cannot do this. It’s worth asking any contractor you’re considering what happens to your schedule if they open the wall and find mold.
As of 2026, a full gut renovation of a standard Weymouth bathroom runs roughly $18,000 to $32,000 with mid-range finishes. Smaller scopes cost considerably less — a cosmetic refresh starts around $3,500, and a powder room lands in the $5,000 to $10,000 range.
| Scope | Typical 2026 range (eastern MA) |
|---|---|
| Cosmetic refresh — vanity, fixtures, paint, no tile | $3,500 – $8,000 |
| Powder room / half-bath renovation | $5,000 – $10,000 |
| Tile and surface update, layout unchanged | $6,000 – $12,000 |
| Tub-to-shower conversion | $8,000 – $18,000 |
| Full gut, standard 5×8 bathroom, mid-range finishes | $18,000 – $32,000 |
| Master bathroom, upgraded finishes | $30,000 – $55,000+ |
| Add: relocating plumbing fixtures | $2,500 – $5,000 |
These are market ranges, not our quotes. Massachusetts averages around $17,600 for a bathroom remodel with most projects falling between roughly $8,800 and $25,000, and Greater Boston and the South Shore run meaningfully above national figures because of labour rates, older housing stock and stricter code enforcement.
On small bathrooms specifically: a small bathroom renovation in Weymouth costs less in total but more per square foot than a large one. Every bathroom needs the same plumbing rough-in, the same electrical, the same waterproofing and the same inspections whether it’s 35 square feet or 90. What scales with size is materials, and materials are the smaller half of the bill. Homeowners are often surprised that their 5×7 bathroom isn’t half the price of a master — it’s usually closer to two-thirds.
The one decision that moves the number most: keeping the existing layout. Leave the toilet, sink and shower where they are and you avoid moving wet lines entirely. Move them and you add cost before a single tile is laid.
Three to five weeks for a standard full renovation, assuming selections are made before demolition and inspections land on schedule. Add time for extensive rot or mold remediation, custom vanities or tile with long lead times, and layout changes that move plumbing.
If it’s your only bathroom, say so at the estimate. We sequence single-bathroom projects differently — compressing the unusable window rather than working the most efficient order for us — and it’s worth planning around rather than discovering in week two.
One Weymouth-area homeowner hired us for a guest bathroom after neighbours recommended us for exterior painting, then booked their master bathroom immediately after the first one finished — two to-the-studs projects in a single year. Another repeat client had us do a complete bathroom redo alongside their kitchen renovation. Doing two rooms in sequence with one contractor is usually cheaper and far less disruptive than two separate projects a year apart.
Weymouth requires permits for bathroom renovation work — building, plus separate plumbing and electrical permits pulled by licensed trades. Current requirements are on the Town of Weymouth building permit page. We handle all of it, and we schedule the inspections.
On “bonded”: Massachusetts doesn’t work the way that word implies. Home Improvement Contractors here aren’t required to carry a surety bond. Instead, every registered HIC pays into a state Guaranty Fund, which compensates homeowners up to $25,000 for unpaid judgments against a registered contractor. That protection only exists if your contractor is registered — hire an unregistered one and you have no access to it, and no access to the state’s arbitration programme either.
So the questions worth asking are: are you registered, are you insured, and do you carry workers’ compensation. We’re registered, fully insured, carry workers’ comp on every crew member, and operate under Massachusetts Contractor License 186517. You can verify any Massachusetts contractor’s registration through the Office of Consumer Affairs and Business Regulation before you sign anything — ours included.
One more thing the law requires: any home improvement contract over $1,000 in Massachusetts must be in writing, signed by both parties, with a payment schedule. If a contractor wants to work off a handshake, that’s not a shortcut — it’s a warning.

How much does a bathroom renovation cost in the Weymouth area?
A full gut renovation of a standard bathroom runs roughly $18,000 to $32,000 with mid-range finishes as of 2026. Powder rooms run $5,000 to $10,000, and a cosmetic refresh can start around $3,500. A master bathroom with upgraded finishes typically lands between $30,000 and $55,000. Keeping the existing layout is the single biggest saving available.
Do you offer free bathroom renovation consultations?
Yes. We walk the room with you, discuss layout and materials, and provide a written scope with fixture allowances at no cost. If a smaller job than you were expecting is the right answer, we’ll say so.
What does a full bathroom renovation include?
Demolition to the studs, new plumbing and electrical rough-in by licensed trades, ventilation, waterproofing membrane and substrate, tile, vanity, countertop, fixtures, shower glass, finish carpentry and paint — plus permits, inspections and a final walkthrough. Any rot, mold or structural repair found during demolition is addressed before the walls close up.
Are you a fully insured and bonded contractor?
We’re fully insured and carry workers’ compensation on every crew member, and we hold Massachusetts Contractor License 186517. Worth knowing: Massachusetts doesn’t require Home Improvement Contractors to be bonded. Instead, registered contractors pay into a state Guaranty Fund that compensates homeowners up to $25,000 for unpaid judgments — a protection only available if your contractor is registered. Verify ours, and any contractor’s, through the Office of Consumer Affairs and Business Regulation.
Do you offer financing for a bathroom renovation?
Yes. We offer customised financing on renovation projects — ask during your free consultation and we’ll walk you through the options alongside the written estimate.
