Yes, our units can be set up inside PROVIDED there is sufficient room. For inside set ups you will need to have enough ceiling height to accommodate the unit with ample clearance space from any lights, vents or any other hazards that may be present. Some units are 18 ft. high. Generally garages, basements, family/rec. rooms in residential dwellings do not accommodate the height or overall size of our units. Many commercial halls, school gyms, park & rec. facilities, church halls, town meeting rooms, etc. will do just fine however. You, the customer are responsible to ensure the inflatable will fit. If the unit does not fit once we arrive payment is still due in full.
