Four seats in a compact barrel
The No. 53 seats four inside a 6.06-foot diameter, with 19.5-inch-deep Thermo-Aspen benches and a glass front door that lets in daylight. At 71 in. long, it keeps a modest footprint.
Thermal modification uses only heat and steam, with no chemicals, to give real wood more strength and stability through changing weather. The modified wood also insulates better than untreated wood, so it stays comfortable underfoot.

Date night at home
Thermory's 50 Series “Cozy” barrels are made for two, and the No. 53 stretches to four. A rain jacket for all-weather protection comes with every kit.

Deep benches in a 6.06-foot barrel
19.5-inch-deep Thermo-Aspen benches run the length of the barrel, giving each bather room to settle in.

Choose the heater that fits
Thermory shows its 50 Series barrels with Wi-Fi enabled HUUM heaters. Your kit ships without one, so pick a heater from the options above Add to cart and Inland will help size it to the room.

Heat and steam, nothing else
Thermory's chemical-free thermal modification enhances real wood with heat and steam alone. The result is strong, stable timber that holds its shape as the weather changes and stays comfortable on bare feet.
