With the extra large bowl of the Opal S2 stainless steel sink, you’ll be able to clean grill pans and large trays by laying them flat. And if you team it with the Opal H1, you have an extra half bowl to use when the main bowl is full. All our Opal sinks are made with premium grade stainless steel and have a coating on the back to deaden the sound of water flowing into the bowl. This also keeps the water hotter for longer, so you save energy too. Opal must be undermounted onto a solid worktop.
