Vertical plane circumscribing the bath tub or shower. Note: For showers without a basin, the limiting vertical plane of zone 1 is at a distance of 1.2m from the centre point of the fixed water outlet on the wall or ceiling.

This is the three-dimensional space between the following boundaries: Horizontal plane: Between the finished floor level and the highest point of either the highest fixed shower head or water outlet or 2.25m above the finished floor level. Vertical plane: The parallel vertical surface that is 60cm from the zone 1 border. Note: For showers without a basin there is no zone 2. An increased zone 1 is provided by the horizontal height of 1.2m.
