For hydrotherapy and pleasure: the $42,000 hot tub boat

Experience comfort, relaxation and revolving scenery.


The earliest hot tubs were calderas in which hot stones were placed to heat the water. Nowadays, the hot tub fans will bring their oasis of hydrotherapy or pleasure on the water thanks to hot tub boat, an electric boat with a hot tub built into its deck.

A 24-volt electric motor propels the boat up to 5 mph on calm water, steered via a joystick by a bather located starboard/aft. Its rechargeable battery bank provides up to 10 hours of power from an overnight charge using its built- in Smart Plug shore power connection and on-board chargers.

Engineered and built in Seattle, WA by a marine carpenter that specializes in custom house boats, the craft’s Vinylester hull is topped with a slatted deck handcrafted from African teak. The hot tub (8′ L x 4′ W x 24″ D) is positioned on the boat’s center of buoyancy, providing the boat exceptional stability. It drafts only 20″, even when filled with its maximum load of 2,100 lbs. of water and six adult bathers.

An integrated diesel-powered boiler with an adjustable thermostat heats the tub’s water to a maximum 104° F. A waterproof stereo system plays music from your MP3 player through two flush-mounted 50-watt speakers that pop-up from the deck. Four ice chests built into the deck provide ample storage for your preferred libation with additional storage compartments fore and aft. A teak swimstep provides easy entry into and from the surrounding water.
