Randolph · Walk-In Showers
Building a walk-in shower in Randolph? Learn how the town's permits and plumbing inspections fit the job, then call or send a request to reach an independent local remodeler.
Randolph, Massachusetts
The parts of a walk-in shower that decide whether it lasts are the ones you never see again: the drain body, the trap, the sloped base, and the waterproof layer over it. In Randolph, the plumbing inspector has to see the new drain and supply work before any of that gets covered, and the town posts that inspector's hours as three set weekdays.
That makes the calendar part of the design. A remodeler who plans the rough plumbing to be ready on an inspection morning keeps the project moving; one who doesn't may leave you with an open floor and a waiting tile setter. Ask about it up front, along with how the base will be pitched toward the drain and how the curb, if there is one, will be built.
South Shore Bathroom Remodeling Finder doesn't build showers or send crews. We put Randolph homeowners in touch with independent remodelers who serve the town, and the choice of whether to hire one stays with you.
If anyone in the house grips the towel bar to climb in, a low curb or curbless entry removes the riskiest moment of the day.
A tub used only as a shower takes floor space without earning it. A walk-in layout can reuse the same footprint with a wider opening and a built-in seat.
Recurring cracks or soft spots near the base can point to movement or water under the surface. Rebuilding the base properly is a good reason to change the whole shower.
Recessed niches and a bench give bottles a place to sit. They're easiest to add when the wall framing is already open.
Local knowledge
Three local details shape how a Randolph walk-in shower gets permitted, inspected, and drained.
Inspection Days
The Building Department lists plumbing inspector hours on Monday, Wednesday, and Thursday, with requests called in before 9:00 a.m., a schedule posted through the end of 2026. Your rough-in inspection has to land on one of those days before the base is waterproofed and tiled.
PermitEyes Filing
Randolph takes plumbing, building, and electric permit requests through PermitEyes. A new shower valve and drain call for a plumbing permit, and a new light or fan over the shower adds an electrical one.

Where Water Goes
MWRA counts Randolph among its sewer-only communities, so homes on the town sewer send shower water into the regional system. If you're adding a second shower and don't know how your house connects, ask the town's Water and Sewer Division first.

Right now
A little homework makes the first site visit more useful.
Note the width and depth of the current tub or stall, the door width, and where the window sits. Those numbers tell a remodeler quickly whether a curbless layout is realistic.
Know where the main valve is in case a supply line weeps during demolition. Look where the water service enters the house, often in the basement.
A shower for a teenager and one for a parent with a cane call for different seat heights, grab bar spots, and valve placement. Write down who will use it most.
Pictures of tile, glass, and drain styles help a remodeler price your actual taste instead of a guess.
What to expect
On the first visit, a remodeler should check the floor framing under the shower, find where the drain can run, and look at the valve wall. Expect questions about curb height, glass, and whether you want a bench or handheld sprayer, since each one changes blocking and plumbing.
Once work starts, the order matters. Demolition comes first, then framing repairs, then the plumber sets the drain and valve under a permit filed through PermitEyes. The rough plumbing is inspected on one of the inspector's set days. Only then does the base get its slope and waterproofing, followed by a flood test, tile, grout, and glass.
Ask for that flood test in writing: the base is plugged and filled with standing water for a period long enough to show it holds. It's the last good chance to find a leak before tile hides it.
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.
Look up the remodeler on the state's Home Improvement Contractor search. Registration is required for remodeling owner-occupied homes of one to four units.
The drain and valve work must be done by a plumber who holds a Massachusetts license, under a Randolph plumbing permit. Get the plumber's name and check the license.
A remodeler who works in Randolph should know the inspector's set days. Ask how they'll time the rough-in so the job doesn't stall with an open floor.
The contract should say which waterproofing method will be used and that the base will be flood-tested before tile goes down.
Costs
The size of the opening, the curb choice, and the drain location set most of the labor. A curbless floor often means recessing or reframing the subfloor, and a linear drain or a moved drain adds plumbing time. Glass, tile size, niches, and benches add to materials and setting time.
Ask each remodeler for a written, itemized estimate on the same scope, including permits, demolition, disposal, and a stated allowance for framing repairs. If an estimate is a single number with no breakdown, ask for the details before you compare it to others.

Still not sure? Send a short request and a local pro can answer the specifics.
Yes, when the drain, trap, or valve is installed or changed. In Randolph the plumber requests it online through PermitEyes, and the rough work is inspected before it's covered.
The rough plumbing has to pass inspection first, and Randolph's plumbing inspector works set weekdays. A good schedule plans the rough-in to be ready on one of those mornings.
Sometimes. It depends on the floor framing, the room below, and where the drain can run. A remodeler can tell you after opening or inspecting the floor.
The scope, materials, waterproofing method, flood test, start and finish dates, payment schedule, and the names of the plumber and electrician. Massachusetts home improvement contracts shouldn't have blank spaces.
