A mitred grate and drain cover comprises a peripheral edge having an upper and lower surface and a substantially elliptical shape which defines a space, and a plurality of cross pieces within the space. Depending sidewalls extend from the lower surface of the peripheral edge, and are constructed with respect to the peripheral edge such that they are at an angle other than 90° to the peripheral edge. The sidewalls define a space for receiving a pipe.
