Hull · Tub-To-Shower
Swapping a tub for a shower in Hull? Learn what older supply pipes, Weir River water testing, and part-time town inspectors mean for the job, then reach an independent remodeler.
Hull, Massachusetts
Taking out a tub opens the one wall in the bathroom where most of the plumbing lives. The valve, the supply pipes feeding it, and the drain under the tub are all exposed at once, and in Hull that's often the first look anyone has had at them in decades: Census estimates count 2,550 of the town's 5,838 housing units as built in 1939 or earlier.
Hull's water comes from the Weir River Water System, which also serves Hingham and North Cohasset. Its 2025 water quality report says one sampling location exceeded the lead action level that year, and the system adds lime and zinc orthophosphate to control corrosion. Neither fact means your own pipes are a problem, but an open wall is the easiest moment to ask a plumber what your supply lines are made of.
No one at South Shore Bathroom Remodeling Finder pulls out tubs. We link Hull homeowners with independent remodelers who take conversion work in town, and the hiring decision stays with you.
If nobody has filled the tub in years, a full-size shower puts the same footprint to better daily use.
An old two- or three-handle valve that drips or swings between hot and cold is due for replacement, and a conversion puts a modern pressure-balancing valve within easy reach.
Staining at the spout or flaking around old fittings deserves a plumber's look, and the conversion opens the exact wall where those fittings hide.
A low curb in place of a tub wall is a common reason for the swap, and the existing alcove usually fits a shower without moving walls.
Local knowledge
Water testing, service line records, and inspection scheduling are the local details worth knowing.
Lead Monitoring
The system's 2025 report found one location over the lead action level and none over the copper action level. If your conversion exposes old supply piping or fittings, ask the plumber whether replacing them now makes sense.
Service Line Records
In March 2026 the system said it was in full compliance with the Lead and Copper Rule, and that the revised rule focuses on identifying what each customer's service line is made of. While a plumber is in the house, ask them to note what the pipe looks like where it enters.

Part-Time Inspectors
The Building Department says its plumbing and gas inspectors are part-time and should be called directly to set up inspections. Build that call into the schedule so the rough plumbing is approved before the new walls go up.

Prewar Housing
Tubs in houses that age may sit on cast iron drains and on joists notched by earlier plumbers. Plan for the remodeler to repair framing before the new shower base goes in.

Right now
A few quick checks make every estimate more accurate.
If it's the only tub in the house, think about young children, pets, and future buyers before you remove it.
The Weir River Water System publishes a report every year. Read the lead and copper section so you can ask informed questions about the pipes in your own walls.
Know where water enters the house and how to close it. The crew will need it, and so will you if a fitting lets go during the work.
If a finished ceiling sits under the tub, say so up front; the remodeler may need access from below to reach the drain.
What to expect
Demolition usually removes the tub, the surround, and enough wall to reach the valve. The plumber then sets a drain for a shower base or a tiled pan, replaces or updates the valve, and leaves the rough work open for inspection.
In Hull, the plumbing permit can be applied for online, but the inspection is booked by calling the part-time inspector directly. Any building permit for the remodeling side goes to the Building Department on paper, by mail, drop box, or in person, with the contractor's HIC and Construction Supervisor credentials attached.
Once the rough plumbing passes, the crew installs backer board and a waterproof layer, then tile or panels, glass, and trim. Ask the plumber to tell you what the supply lines are made of while the wall is open, and get that note in writing for your records.
Hire smart
In Massachusetts, contractors who remodel an existing owner-occupied home of one to four units must be registered Home Improvement Contractors, and the plumbing and electrical parts of the job must be done by a plumber and an electrician who hold Massachusetts licenses, under permits.
Massachusetts requires Home Improvement Contractor registration for remodeling owner-occupied homes of one to four units. Look the contractor up before you pay a deposit.
Find out whether the plumber or the remodeler will phone Hull's inspector, and how the crew will keep the job moving if the inspection date slips.
Request a separate line for replacing old supply piping back to a sensible point, so you can decide on it before demolition rather than in the middle of the job.
The valve and drain work must be done by a plumber who holds a Massachusetts license. Get the name and check it on the state's lookup.
Costs
A prefabricated base and wall panels set in the old alcove usually involve less labor than a tiled pan with a niche and a bench. Moving the drain, replacing old supply pipe, or repairing joists under a prewar tub all add to the scope.
Get written, itemized estimates that describe the same conversion so you can compare them fairly. Ask how each remodeler will handle surprises once the tub is out, and whether pipe replacement is priced as its own line.

If the wall is open and the pipes are old, it's worth asking. The Weir River Water System's 2025 report found one site over the lead action level, and a plumber can tell you what your lines are made of and whether replacing them now is sensible.
Hull's part-time plumbing inspectors, who work through the Building Department. The plumbing permit can be filed online, and the plumber calls the inspector directly to set a time.
It depends on who lives there and who might buy later. Some households with small children want a tub, while others would rather have a roomier shower. If you're unsure, ask the remodeler whether another bathroom could take a tub down the road.
That depends on the scope and on when the inspection can be scheduled. Ask the remodeler for written start and completion dates and how an inspection delay would shift them.
