I took the time to ask the experts at kitchenaid via this website if this bowl is compatible with my stand mixer. They replied promptly that it was compatible; sadly' it does not fit and now I'm stuck dealing with the hassle of returning the bowl. 

Here is my question and the reply from kitchenaid: 

Is this compatible with KSM5BBU? And, if it is not compatible can you suggest another smaller bowl that would work? Thank you very much for your help.

Hi TootsMcGee, The KN3CW, 3 Qt. Bowl and Combi Whip is compatible with the KSM5BBU model stand mixer.
