Groton sits on the Thames River in New London County, across the water from New London. The Naval Submarine Base New London is here, and the town builds submarines at Electric Boat.
The Submarine Force Museum and the historic ship Nautilus draw visitors to the riverfront, while Bluff Point State Park and Eastern Point Beach mark the town's Long Island Sound shore.
For Groton homeowners, Being Sauna arranges wet-area help: vetted local specialists, honest planning ranges published up front, and a free in-home assessment ending in a written quote.
In short: Bathroom remodeling in Groton, Connecticut covers the wet area: tub-to-shower conversions ($8,500-$17,000), shower replacement ($7,500-$15,000), walk-in showers ($9,000-$18,000) and tub replacement ($6,500-$13,000). Vetted local specialists serve Groton and ZIP 06340. Call (833) 334-4470.
Six services, one specialty — the tub and shower. Each card links to its full guide, and the ranges below are what Groton homeowners actually plan around.
Start with the guide that matches your room, then compare it with the cost table further down the page. For the full picture, see all our bathroom remodeling services.
Many Groton ranches and base-area homes still hold an original tub in a compact bath, and stepping over its high side gets harder with time. A low-entry shower replaces it, with pan, valve and drain renewed together.
Years of daily use wear a Groton shower down: a valve that drifts hot and cold, a tired pan, or a drain from an older plumbing era. Pan, valve and walls are replaced together while the old unit is out.
A low-entry shower with a bench, anchored grab bars and controls within reach helps a Groton home stay workable as needs change. Blocking for the bars goes into real structure behind the tile.
Some Groton households still want a real tub — for young children, for a long soak, or for a second bath in a busy family home. A deeper modern tub usually fits within two days.
A shower-only Groton home can get a tub back without moving walls. A tub-shower combination returns, with renewed plumbing underneath and waterproofing behind the walls, built for family use.
Whole-room reworks for Groton baths where tub and shower both need attention at once, or where a dated base-era bath needs a fresh start. One project, one written quote, wet area first.
A tub-to-shower conversion turns the unused tub in a Groton ranch bath into a low-entry shower — pan, valve and drain renewed together.
Groton sits in the southeastern Connecticut contractor market, with crews working the Thames corridor toward New London, Mystic, Stonington and Ledyard.
Most jobs land in the middle of these ranges, and the spread comes from the house, not the ZIP. A simple alcove swap is an easier job than a coastal cottage bath whose original drain and supply lines need work.
The upper half of a range is priced in the written quote before work begins. For the method behind every figure, see the 2026 bathroom remodeling cost guide.

Planning ranges based on published national installer pricing (2026), for budgeting guidance — not quotes. Compare quotes on what they cover: pan, valve and drain together.
The cheapest number often leaves a worn drain or tired valve behind new walls. Full methodology: the 2026 cost guide.
Groton grew from a Thames River settlement into a submarine town, and its bathrooms show both stories: base-era ranches, river cottages, and newer subdivisions off the coastal roads.
The Groton service area covers about 29,863 people in ZIP 06340, with Groton center, the submarine base, Avery Point and the Sound shore at its core.
The Nautilus, Fort Griswold and Bluff Point anchor the area, and the homes around them hold some of southeastern Connecticut's most practical coastal baths.
Base-era ranches hold compact baths with older plumbing runs, and a remodel measures those rooms carefully before choosing fixtures. The goal is a modern wet area that fits the home's bones.
Thames River cottages add smaller baths with tight footprints and coastal wear. Newer subdivisions bring larger baths with original tubs and showers from their build era. Each home type gets measured on its own before any quote is written.
Most Groton homes use town water, so the assessment starts by confirming pressure and flow at the fixtures. Older supply lines from earlier plumbing eras get checked at the same visit.
Some homes on the outer edges rely on wells or septic systems, and those setups change the checks, not the goal. Drains, valves and water pressure are inspected before any new fixture goes in.
Groton winters bring freeze nights and coastal storms, and both test exposed pipes and older seals. Shut-offs are confirmed before the cold arrives, so a cold snap never becomes a leak behind new tile.
Summer brings Sound-side humidity, so ventilation and seals get checked in the warm months. The assessment covers both seasons, keeping the new wet area sound year-round.

Nothing fancy — just four things that help the specialist price your Groton bath on the first visit. Know the home type: base-era ranch, river cottage, subdivision home or condo.
Note any history of slow drains, temperature swings, or older plumbing quirks. Bring a rough footprint measurement and note whether a second bath exists, so the household keeps a wash-up option during the work.
Settle which outcome matters most first — safer step-in shower, deeper tub, or full-room rework — so the quote prices the right job. For condos, confirm building approval before the visit too.

We publish planning ranges on every page. No “call for price”, no games — you budget before anyone visits.
The price you sign is the price you pay. Quotes are written, itemised and valid beyond the day of the visit — take your time deciding.
Installers are independent local contractors checked for licensing, insurance and wet-area specialisation before they take a single Being Sauna job — including experience with coastal humidity, salt air and base-era baths.
The biggest complaint in this industry is the same-day pressure close. Our specialists are instructed the opposite way: measure, explain, quote in writing, and leave the decision to you.
Call (833) 334-4470 or send the assessment form. Tell us the neighborhood, the bath, and whether the home is a base-era ranch, a river cottage, a subdivision home or a condo — that is all the booking needs.
A vetted local specialist measures the room, checks the valves, drain, ventilation and water setup, and explains the options in plain language. No charge, no obligation.
Most wet-area projects finish in one to three days, with the house left clean and the new shower or tub demonstrated before the crew leaves.
Most wet-area projects in Groton follow the planning ranges on this page: tub-to-shower conversions $8,500-$17,000, shower replacements $7,500-$15,000, walk-in showers $9,000-$18,000, bathtub replacements $6,500-$13,000, shower-to-tub conversions $7,500-$14,000 and full remodels $15,000-$35,000+. Your exact price is confirmed in writing after a free in-home assessment.
Often, yes. Many Groton ranches and base-area homes were built around a single tub alcove, and a low-entry shower usually fits that same footprint. The assessment measures the alcove, checks the drain position and confirms valve placement, then prices the swap as a same-footprint job when the layout allows it.
Salt air and river humidity test seals, grout and ventilation more than an inland bath faces. The assessment checks the fan, confirms the vent path and specifies sealed walls and grout, so moisture leaves the room instead of sitting behind new tile. Ventilation is priced into the written quote, not added later.
Check the drain, the supply lines and the valve before choosing fixtures. Older Groton plumbing runs can hide worn parts that a new tub would only cover up. The free assessment inspects those parts first, and any replacements are priced into the written quote, so the new wet area sits on sound plumbing.
