Wikipedia
A beach hut (also known as a beach cabin or bathing box) is a small, usually wooden and often brightly coloured, box above the high tide mark on popular bathing beaches. They are generally used as a shelter from the sun or wind, changing into and out of swimming costumes and for the safe storing of some personal belongings. Some beach huts incorporate simple facilities for preparing food and hot drinks by either bottled gas or occasionally mains electricity.
