How to Use Bounce House Rentals Indoors (Safely) in Winter

Many bounce house rentals in Ontario include indoor‑friendly units. Ask for:

Low‑profile inflatables: Check ceiling height; 8–10 ft minimum is common for compact castles.
Non‑marking floor protection: Tarps and mats under all gear; entrance/exit mats to reduce slips.
Power and cords: One blower per dedicated 120V/15A circuit with GFCI protection. Use CSA‑approved extension cords and cord covers.
Supervision plan: Follow posted user limits; group kids by size; socks only; no food/drinks on the unit.
Weather policy: Ontario winters can be icy—confirm rescheduling terms and indoor delivery logistics (boot trays, clear sidewalks).

Pro tip: If you’re booking a community centre or gym, share the exact room dimensions, door widths, and any elevator/stair details with your provider.
