The Water Tag Maze is best for little ones at heights of 4 feet and shorter. The unit measures 25’Long x 25’Wide x 4′ Tall. 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 28’x28′ area for set up. This exciting water tag maze comes with 10 water guns and hours of fun! You do need a water source for this unit.
