A refrigerator comprising:

• a cabinet comprising:
• an inner case that defines a storage compartment, the inner case having a bottom surface that defines a water collection hole at a rear end,
• a case supporter that is coupled to a lower side of the inner case and that supports the inner case,
• a base that is coupled to a lower side of the case supporter, wherein the base and the case supporter define a cavity therebetween,
• a water collection guide mounted on the lower side of the inner case and configured to guide water downward from the water collection hole, and
• a water collection portion disposed on the base and configured to collect water from the water collection guide;
• a door disposed on a front portion of the cabinet and configured to open and close at least a portion of the storage compartment;
• and
• a cooling device disposed on a rear surface of the inner case, at least a portion of the cooling device being exposed to the storage compartment,
• wherein the water collection guide comprises:
• a contact portion that is coupled to and in contact with an outer surface of the inner case, and
• a water collection pipe having a guide hole configured to fluidly communicate with the water collection hole,
• wherein the case supporter comprises a guide pipe that receives the water collection pipe, and
• wherein the guide pipe has:
• an upper end that extends upward from an upper surface of the case supporter and that connects to a lower end of the water collection pipe, and
• a lower end that extends downward from a lower surface of the case supporter and that is configured to guide water discharged from the water collection pipe toward the water collection portion.
