Banya Boat is a floating banya moored at a marina on Westlake Avenue, on the west shore of Lake Union, and it never leaves the dock. Each booking has the whole boat to itself, with no outside guests. The rhythm is heat, cold and rest, repeated: a cedar dry sauna and a steam room for the heat, a cold plunge and a bucket shower for the cold, and a wood-fired hot tub, an indoor lounge and an upper deck over the lake for the time in between. Heat and cold on the water The cedar dry sauna runs at about 185°F beside a glowing wall of Himalayan salt blocks, and its windows look straight out over the lake.
