Basins at least seven inches deep are more practical than shallower offerings. Stainless steel may be standard. The more nickel, the higher the quality, too. Ten percent nickel is best. Determine if the enamel sink in the model is an upgrade.
Some sinks come with attached drainboards.
Rimless sinks are easier to keep clean. Look for faucets that pull out to clean the sink as well as big pots. Range hoods come in a hundred sizes and shapes. While space and budget determine styling options, look for vents that pipe smoke outside. Some just filter.
