The 20x20ft Rainbow Party Adult Bouncy Castle offers a large bouncing activity for adult parties and family events. Its footprint makes it a choice for larger venues, so check the required setup area and delivery access before booking.
Planning the hire
Check the listed dimensions, required space and suitability for the guests attending. Tell us about gates, doorways, ceiling obstructions and power before booking so we can help agree a workable setup. Our team will explain how to use the equipment at delivery.

Why choose The Party Doctors for your event?
We are a family-run hire company operating full-time, backed by over 20 years of experience. That means you have an experienced team to speak to about your plans, with equipment care and preparation built into our daily operation. Our customer feedback and guide to choosing The Party Doctors explain the service in more detail.
Space, access and power
Before booking, check the product’s stated dimensions and suitability, including ceiling height for indoor venues and clear access for our delivery team. Tell us about steps, narrow gates or restricted access in advance. We supply and set up the equipment, then explain its use at handover. For blower-powered inflatables, a suitable mains socket is normally needed within 25 metres of the blower; discuss alternatives with us if power is unavailable.
Outdoor hire and the weather
For outdoor inflatable hire, we install on suitable natural grass only. We do not set up on concrete, tarmac, patios or artificial grass. Our guide to surfaces and anchoring explains why. Outdoor hires also depend on suitable weather; read our wind-speed guide before planning your event. From November to April, our inflatable hires are indoors only.
Equipment care and inspections
Our applicable inflatables have an annual inspection against BS EN 14960 requirements, supported by maintenance and checks before use. We use PIPA/RPII testing and inspection: some new equipment has a PIPA test from its manufacturer, and ongoing annual inspections are carried out by an approved RPII inspector. Learn more about our inspection arrangements.
Supervision and safe use
A responsible adult aged 18 or over must supervise equipment left in your care throughout the hire. Follow the product’s user limits and the instructions given at setup. Our bouncy castle safety information and health and safety guidance explain the wider precautions we take.
Ask us about your event
Check availability and the booking total for the date and hire period you need, including any delivery charge or selected extras. If your venue has fixed access times, or you need a different collection arrangement, speak to us before booking. We can help match the equipment and timing to your event.
Plan the space and delivery route
Allow space around the castle for safe access, its blower and the anchoring arrangements. For an indoor party, check the lowest ceiling point, including beams and light fittings, as well as the doorway and delivery route. Our venue directory can help with local hall planning.
