The pool can be decorated with colored lamps, the steam room can be provided with overhead and built -in lamps with spotlights. You need to take into account the temperature in the room. In our baths, it can reach up to 70ºС and humidity up to 75%. If we consider Finnish steam rooms, then there is much higher temperature limit (120ºС and only up to 30% humidity). Despite this, the light should be soft and bring people a rest and relaxed communication atmosphere. Lamps and lamps for the hall is best to have behind vacationers, embedding them on the floor or in the ceiling.
