As you choose a compartment sink, there are several options available. A one- or two-compartment sink is great for prepping or washing vegetables, and should be placed at convenient points in the kitchen so that workers do not need to go to the warewashing area to wash and prep food. A four-compartment sink has an extra compartment for prep work, and serves as a good alternative to a three-compartment model. All of the Turbo Air compartment sinks come with heavy duty 304 stainless steel. The TSA models are all 18-gauge, while the TSB and several other models come with higher-quality, 16-gauge steel that will hold up to even the most aggressive commercial applications.
