The Bath tubs, made from Kambala wood, are 7 in total so we can have about 14 people each hour. It is available for people, one at a time, or two together. There is no age limit for the beer bath because the bathwater is undrinkable, but there is a beer draught at every tub for anybody over 20 years of age. 16 years and younger need to be accompanied with adults. When taking a beer bath, you bathe in a big tub filled with beer, water, hops and yeast. After 25 minutes, you get up from the tub and go to a relaxation room for another 25 minutes.
