How to have a seaweed bath

Let me explain …
you pay 20 euros ,go into a tiled room with nothing but a mat ,a towel ,a clock , a polite notice asking you to be quiet and a bath .You lock the door strip butt naked and get into the steaming bath filled with freshly picked seaweed and hot water . You then nearly break your neck getting out as the bath is so slippery .
What you do do is lie back ,relax and soak in the most amazing natural oils and come out looking like an Irish Adonis ( Me and Florence ) .
What you don’t do is …not add cold water and emerge looking like a freshly boiled Kerry lobster ( Jacob )
