The Whirlpool WRT318FZDM is a 30-inch-class top-freezer refrigerator with about 18 cu. ft. total capacity and no through-door dispenser. Its simpler layout does not remove the need for careful depth, hinge, and ventilation checks.
Dimensions that affect the kitchen
Whirlpool lists 65 7/8 inches to the top of the hinge, 29 3/4 inches width, 33 1/2 inches overall depth, and about 59 3/4 inches depth with the door open 90 degrees. It is not a counter-depth model.
The WRT318FZDM product page describes electronic temperature controls, glass shelves, two crispers, and an optional icemaker. Measure wall, island, handle, hinge, baseboard, and delivery clearances. The door may open at 90 degrees yet still lack room to remove bins or shelves.
Ownership costs
A new water line is unnecessary unless adding the optional icemaker. If adding it, confirm the current kit and provide an accessible shutoff with a sound supply line. Level the cabinet and doors, maintain the specified ventilation gaps, and vacuum accessible condenser areas only as the owner guide directs.
Use appliance thermometers to verify temperatures after loading and adjustment. Warm food, blocked vents, poor door sealing, room heat, and control settings can mimic a cooling fault.
Verdict
WRT318FZDM fits a household that wants a conventional top-freezer, no dispenser, and a cabinet just under 30 inches wide. Its 33.5-inch depth and wide door arc are the main fit risks. Whirlpool currently marks availability as variable, so use the exact model search and verify retailer stock rather than substituting a similar suffix.
