A shower tray access ramp comprises a ramp part and a transition part selectively attachable to the ramp part. The ramp part has a first edge for connection to a shower tray, a second edge which is opposite the first edge and which is engagable with the transition part, and a ramp portion intermediate the first and second edges. The second edge includes a flange which is spaced from an upper ramp surface of the ramp portion and which is fastenable to a ramp supporting surface. The transition part has a first transition edge which is seatable on the flange of the ramp part, a second transition edge which is opposite the first transition edge and which tapers to or substantially to a point to provide a transition from the ramp supporting surface onto the access ramp, and a transition ramp portion intermediate the first and second transition edges.
