FAQ
Will an outdoor storage box keep cushions and bikes dry all year?+
Resin boxes like the Keter Store It Out range are fully weatherproof and will not warp, rust or rot, so cushions and bikes stay dry through a UK winter. Check the lid seal and choose a raised base if the box sits directly on grass or soil.
What size outdoor storage box do I need for two bikes?+
Look for at least 1000-1300L capacity, such as the Keter Store It Out Max Plus, to fit two adult bikes plus a little extra room for helmets and locks.
