A:Answer Hi there,
I do apologize and will be happy to provide more clarifying details. The interior dimensions are approximately 21.7"W x 22.2"D.
The side walls of the drawer are not perfectly vertical – the drawer is slightly narrower at the bottom than at the top, like a cup or other large plastic storage bins. The measurements above are at the deepest (narrowest) point, just before the round at the very bottom. The drawer sidewall is 7.48" deep but the cavity for the drawer can have taller items, up to 11.69", placed into the drawer and it will still close. The internal height is 13", but you will need to tilt the object to get it under the c-channel.
The new pedestal is 16-inches (13-inches for old) and can accommodate large Tide bottle upright.
Depth with drawer extended is approximately 44". I do hope this helps. Thanks for choosing GE! Mike@GEA
