Our Rectangular Pools are of substantial size and not just for the kids - there's plenty of room for the grown-ups too! The large outer rings are formed using sturdy and rigid 'L-Beam' construction, and with the heavy duty vinyl used they will last for many years to come.Standard sized inflation valves allow the use of electric, hand or foot pumps - allow a few hours for inflating and filling before use. Once you're done, you can either use a cover to preserve the same water, or empty the pool and pack away into a surprising small box for such a large item
