Low profile trays can be turned into an easy plumb / easy fit trays by adding a riser kit. A riser kit comes with a set of legs and panels to raise the tray up by approximately 100mm to allow the plumbing to be fitted above floor level. Using a riser kit with low profile shower trays also simplifies the tray levelling process and provides easy access to the underneath of the tray for future maintenance. These trays still offer excellent drainage by utilising a large 90mm waste hole and modern hi-flow shower traps can drain the water away at over 50 litres per minute.
