Description
The Seima Arko 203 is a classic oval undermount basin that lets the benchtop do the talking. The whole bowl sits beneath the counter, so you get an uninterrupted run of stone or solid surface with a clean cut-out edge and nothing to catch grime around the rim. It is one of the most popular shapes for a reason: generous 11 litre capacity in a footprint that suits both single and double vanities.
