This Waring WSM10LBL 20 qt. stainless steel bowl is a perfect replacement for the one that came standard with your WSM10L 10 qt. mixer. The mixing bowl holds all of your ingredients as you mix up batches of cake batter, bread dough, icings, and other culinary creations! It is designed so that the compatible accessories will work properly and provide even mixing, so if your bowl is damaged be sure to replace it promptly. It's also a good idea to keep a spare bowl or 2 on-hand so that you can prepare multiple batches without having to wash the bowl in between.
