The shower with a big jet is one of the classic fixtures of thalasso- thermal therapy centres. It may be tense, even a little anxiety-producing - when you are waiting for its impact - holding on tightly to the safety bars at the end of the shower stall (provide for a minimum depth of 3.50 m). Invigorating and tonic, its action is due to its powerful touch, the timing of the hydrotherapist and the temperature of the water.
