The Rainbow with Water Slide and Pool 12 and younger and holds 12-15 children at a time. This unit measures 13′ Wide x 35′ Long x 15′ High. With the set up of every inflatable we ask for 3ft of extra space around the outside, so for this item we would need a 16’x38’x18′ area for set up. The Rainbow Bouncer with Slide offers a bouncy area, water slide AND pool! A minimum of 36′ wide is needed to access set up location. You do also need to supply a garden hose and water supply for this unit.
