The ST-BL1591 brings Santorini’s largest 55-litre single bowl into a straightforward topmount format. The wide basin makes cleaning baking trays, large serving platters and family cookware far more comfortable, while the integrated tap landing simplifies benchtop planning.

Its black granite-rich surface gives the kitchen a strong contemporary statement while providing heat, scratch and impact resistance. Overflow configuration varies by model, and the sink’s factory tap hole must not be altered.
