Choose an undermount basin for the benchtop

An undermount basin is fitted beneath the benchtop, so plan the basin, opening and support together with the top. Compare the external basin dimensions, internal bowl area and depth against the available cabinet space.

Stardust is an oval undermount ceramic design. Oracle is rectangular, while selected finishes such as the matte white Koco provide another way to coordinate the basin with the room.

Check the opening, support and space below

Use the selected model’s installation drawing or template to confirm the benchtop opening and support requirements. Overall external dimensions and internal bowl dimensions describe different parts of the basin; confirm the cutting details with the people preparing the top.

Allow space for the basin body, waste and trap inside the cabinet. Check the position of drawers, shelves, plumbing and any nearby basin before finalising the design.

Match tapware and waste to the selected model

Plan the benchtop or wall-mounted tap position and check the spout reach into the bowl. Confirm whether an overflow is present: Stardust is listed with an overflow, while Oracle is listed without one. Select the waste using the confirmed configuration and outlet details for that model.

Review which wastes, traps, supports and tapware are included or supplied separately. For a basin that sits on the top, compare above-counter basins at Melbourne Bathroom Shop.
