Our Verdict
Whirlpool WRT318FZDW
Whirlpool WRT311FZDW
The Whirlpool WRT318FZDW and Whirlpool WRT311FZDW are almost identical fridges in different sizes. In exchange for the extra 3" of width, the 33" WRT311FZDW offers only a modest 5% jump in usable fridge capacity but a far more noticeable 18% jump in freezer space, making it the better option for bulk shopping if you've got the room for it. The WRT311FZDW also uses a slightly different ice maker with a faster production rate and a higher-capacity tray. However, the smaller WRT318FZDW does run a little more quietly.
