In short

Good to know

Tie up long hair so it stays out of the water. Do not swim or splash; enjoy the bath quietly.

When does this apply?

In the bath, keep your hair out of the water with a hair tie or towel. Voices echo in the bathing area, so speak softly. The bath is not for swimming, so soak in it calmly.

Why?

It keeps the water clean and lets everyone relax. Staying in very hot water for a long time can also make you feel unwell, so do not overdo it.

What to do

  • Tie up long hair with a hair tie or towel
  • Speak softly
  • Take frequent breaks and drink water

Better to avoid

  • Swim or put your head under the water
  • Bathe right after drinking alcohol

Exceptions and differences

Facilities may have detailed rules about children, bathing hours or sauna use. Check the notices in the bathing area.

Manners can differ by region, facility and generation. Local signs and staff instructions come first.
