Spa With A View
104°F water. Easy to drive. Boston Harbor views.
Spa With A View is a Newton, Massachusetts–based company that operates private hot tub boat cruises on Boston Harbor.
The signature offering, the Private Boston Hot Tub Boat Cruise (2 Hours, Up to 6), lets up to six guests float in a warm, 104°F hot tub boat while taking in Boston skyline views, historic ships, and waterfront scenes. The experience takes place in a private, deep Nordic tub mounted on a vessel propelled by quiet electric motors, designed to prioritize comfort and low noise on the water. Each two-hour cruise focuses on relaxed enjoyment of harbor sights, combining warm water soaking with open-air cruising for a unique Boston Harbor perspective. Spa With A View emphasizes privacy and small-group experiences; the trip is arranged for the private party on board rather than public tours. The hot tub maintains a consistent temperature for soaking, and the boat’s electric propulsion minimizes wake and engine noise to preserve a peaceful atmosphere. Locations traversed include central Boston Harbor waters where skyline and historic naval vessels are visible from the deck. The business operates from the Greater Boston area and lists Newton, Massachusetts as its base of operations. Spa With A View provides this single specialized experience to deliver a distinctive blend of waterfront sightseeing, thermal relaxation, and private charter convenience for couples, families, and small groups seeking an unconventional harbor outing. Bookings are scheduled by date and time, with clear communication about departure points, safety guidelines, and what guests should bring aboard.

The person operating the boat must be 21+, complete the captain waiver, and upload a valid driver’s license before departure.
Pack warm layers for cooler months
Even though the tub is hot, temperatures on the harbor can be brisk before and after your soak—bring a beanie and light jacket.
Leave glass on shore
BYOB is allowed but glass containers must stay on land for safety—use a cooler and cans or plastic bottles on board.
