Approx. 36 gallon (30" wide x 24" tall x 15" deep). Hood included but it is in 2 pieces (plastic hinge broke shortly after I bought it). You can probably find a replacement online but I used it "as is" for many years. Light is included. Very heavy (50 lbs. or so) and awkward for 1 person to carry so you should bring a friend when you pick it up. Will need a good cleaning before use since it has been sitting empty for several years. No leaks when I last used it.
