If your bathroom floor doesn't allow you to place your quadrant or offset quadrant shower tray directly to the floor, be this because of the pipework or an uneven floor then you'll need a riser kit and plinth to raise this up from the floor.

Supplied with legs that can be individually adjusted and a 95mm plinth. The maximum height it can be raised is 95mm but the plinth can be trimmed if you wish to have less of a raise.
