Description
The Oros 620 Arqstone Sink from Seima is a deep single-bowl kitchen sink — 620 × 500mm and 257mm deep — hand-crafted in Europe from natural stone with a soft silk-matte finish. Available in Arqstone White or Black, with your choice of three taphole configurations: 1 taphole, 3 tapholes, or no taphole.
The 257mm bowl depth is the deepest in the Oros range — designed for serious cooks who want roasting trays and stockpots to sit fully submerged. 10mm radius corners wipe clean in seconds, an integrated overflow is built neatly into the bowl wall, and the flat rim sits abovemount on solid-surface, stone, or laminate benchtops. An integrated tap landing lets you mount tapware directly through the sink without drilling the bench.
Crafted from solid Arqstone — a dense, non-porous engineered stone — the bowl resists stains, scratches, and heat, and stays hygienic with simple soap-and-water cleaning. Stainless steel basket waste and overflow plate are supplied as standard, with colour-matched options available to complete a fully monochrome look.
Pair with the Seima Cutting Board (compatible with Oros 550, 620, 750, 820 and 822) to extend the bowl’s working surface.
