As the name suggests these 4 Lip Shower Trays have a 20mm high upstand around the perimeter on all 4 sides of the tray. The shower door and screens then sit inside these ‘upstands’ so that water cannot leak from any corner and is retained inside the shower box when in use. All 4 sides of these trays are a ‘finished’ surface, meaning that the tray can be rotated for a variety of install situations to suit individual requirements and the visible surface is white acrylic.
