Apartment-size appliances are available at retailers such as Sears and The Home Depot. Both of these have online listings so potential buyers can get preliminary information. Searching for "apartment size appliances" on the Sears website brings up all applicable appliances carried, including refrigerators and compact washers and dryers.
The Home Depot lists each type of apartment appliance separately, as of 2015. Typing in the word "apartment" in the search box field pulls up a drop down box listing washers, dryers, stoves, etc. Scrolling the mouse over each item brings up a preview box on the right. Clicking on an item pulls up more information. If the user is looking for a particular appliance, typing in "apartment size stove" will just bring up stoves.
