Rantasauna

Rantasauna is located in Otaniemi behind Jämeräntaival 5. Rantsu has two separate spaces; a large space and a small space. These can be rented together or separately. The large space is suitable for sauna evenings with plenty of people or academic seated dinners, while the small space can be used by smaller groups. There is a large barbecue in front of the terrace. There is also a pier, but the shore is very shallow.

Rantasauna is available from 2pm-7am. The sauna in the large space can be heated from 12pm till 3am. The users must warm up the sauna by themselves when arriving by switching on the heater. The maximum heating time is 8 hours. To clean and maintain Rantasauna, it is extremely important that the facilities are empty outside of the user hours. If it is necessary to extend the user hours, this must be agreed on in advance with AYY. Additional user hours will be charged at an hourly rate.

Logs to heat Rantasauna small side can be found from the facility. Be sure to also check the log cabin next to Rantsu! The key to the cabin is found in the facility.
