QUESTION The specs have two different sets of dimensions. We have limited space and need to know for sure.
ANSWER Hello, this item can be mounted to hold either 3 or 5 gallons of trash. If mounted to the 3 gallon capacity, it will measure 15"H x 13.5"W x 8.5"D. If it is mounted to the 5 gallon capacity, it will measure 18"H x 13.5"W x 8.5"D. Thank you!
