The largest Model 114 is 68" long x 48" wide x 61" tall and weighs a mere 65 pounds. One of our customers thought it would make a cool fort for his kids (with some ventilation of course!) The smallest is the Model 106 which is 19" long x 14" wide x 12" tall with all shapes and sizes in between. Colors are a granite gray and a riverbed brown. They are manufactured using an HDPE vacuum forming process that creates a very durable yet lightweight faux-stone that won't chip, crack or fade.
