Ruvati's black solid composite mixing bowl and platform set takes your workstation sink functionality to a new level. Now you can mix your batter, toss your salad, or strain your pasta all on top of your sink. No more messy countertop; all the mess stays on the sink and can be easily rinsed off with your faucet sprayer. The platform is designed to fit all Ruvati workstation kitchen sinks including single tier (Roma, Verona and Siena series) as well as dual tier sinks. The black composite platform sits on the ledge of your workstation sink. The set includes a mixing bowl and a perforated colander, both of which fit in the platform and can be nested when not in use. The 5-quart size mixing bowl has a silicone non-slip bottom for ease of use and storage. The set includes a BPA-free black plastic lid that fits tightly on both the mixing bowl and the colander, as well as 3 different grater and slicer attachments. All stainless steel parts are made of food-safe, corrosion-proof T-304 grade stainless steel, one of the highest grade steel available for residential use. All the added utility of this set makes it a perfect addition to any home chef's kitchen.
