The Event Shower WK4 is ideal for a Kneipp hot-cold change shower (from the legs in direction of the heart) by side nozzles. After the start of the programme by a button the light in the shower changes from white to blue. The lowest pair of side nozzles at the level of the legs starts to spray cold water. After an adjustable time the pair of nozzles at the level of the hips follows, then the pair of nozzles at the level of the stomach followed by a pair at the level of the shoulders. Now the temperature changes from cold to warm water, the light changes to red and the 4 pairs of nozzles work in the opposite direction. After the end of the programme the illumination changes back to white and the nozzles are switching off.
