what is the diameter of this pool

Hello Stephen and thank you for your question. If you scroll down the right hand column of the page, you'll see the area where you can order online. The first step is to select the diameter of pool you want. The Belize Round above-ground pool starts at a 12 foot diameter, then 15, 18, 21, 24, 27 and 30 foot diameters. As you select the pool size, you will be presented with all options for that specific size of pool.
