Each Ice Barrel model is unique in its own way. When considering which is best for you, consider climate, accessibility, and how you will use the barrel. The 300 is shorter and wider, so it is easier to enter and exit without using a step stool. It's also fully insulated and has built-in chiller ports, so it's a great choice for those who live in warmer climates. The 400 is taller, so it allows for a more relaxed upright position—especially for people over 6 feet tall. It comes with a step stool for easy entry and exit. The 500 is the largest, comfortably fitting most body sizes up to 6'9" tall with built-in stairs and an interior seat. It's also fully insulated with built-in chiller ports, ideal for warm climates or high-volume use.
