The water is hot, usually about 38 to 42 °C (100 to 108 °F). A modern furo may be made of acrylic, and the top of the range models fitted with a re-circulation system (oidaki) which filters and re-heats the water. This system is connected with the hot water heater, either gas/propane fired or electric/heat pump types.
A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C. These low temperatures are used to collect liquids after distillation , to remove solvents using a rotary evaporator , or to perform a chemical reaction below room temperature ...
Water above these temperatures can cause scald injuries. Many countries, states, or municipalities now require that the temperature of all bath water in newly built and extensively refurbished domestic properties be controlled to a maximum of 48 °C (118 °F).
Whirlpool tubs: These tubs release sprays of heated bubbles (air walk-in tub), water (hydrotherapy walk-in tub), or both to massage sore muscles. The whirlpool gives the tub a Jacuzzi-like feel.
