Living in a hotel, I feel I can't find a place to wash my hair. The sink is too small and the bathroom smells bad. Where do you wash your hair?

If you stay in a hotel and feel that the place where you don't wash your hair is small, use a shower head. There should be a bathroom with a bathing place in the bathroom. Just wash your hair in the bath. Wouldn't it be more convenient to wash your hair with a shower head? Don't use his hygiene, just use the shower head to wash your hair and take a bath.
