Lake Union Hot Tub Boats is a family-owned Seattle business offering wood-fired hot tub boat rentals on Lake Union, giving guests a distinctive way to soak in the city’s skyline while floating on the water. The boats are imported from the Netherlands and built in the tradition of European spa culture, with an extra-deep design that sits low in the water, putting Lake Union at eye level while staying warm inside.

Every boat features adjustable wood-fired heat, fueled by clean-burning recycled logs, and an electric motor with simple steering, letting guests captain their own boat around the lake at their own pace. The tubs are filled with pure, fresh water and double as launchpads for guests who want to jump straight into the lake and climb back up the ladder, repeated as many times as desired, in any season, from a dreamy summer float to a bracing winter dip. On-board storage holds snacks and drinks, and guests are welcome to bring their own beverages along for the ride.

Guests take in 360-degree views of Seattle, from Gas Works Park to the downtown skyline, with many reviews highlighting sunset and moonrise views as a particular highlight. The business can accommodate solo dates or larger celebrations, offering one, two, or three boats at a time, so a birthday party of up to 18 guests can be split across multiple hot tub boats for a joint outing.

A 2-hour, all-in adventure for up to 6 people starts at $400. Reviews consistently praise the friendly, helpful staff, who walk guests through operating the boat before departure, and describe the experience as a can’t-miss, only-in-Seattle activity regardless of season or weather.

For anyone in Seattle looking for a unique, relaxing way to explore Lake Union, Lake Union Hot Tub Boats offers a family-owned, wood-fired hot tub boat experience with room for solo outings or larger group celebrations.
