Buying Guide
What size should you choose? Consider the volume you need. Large backyards benefit from 150-gallon or 100+ gallon boxes, while balconies or sheds can use 31–90 gallon boxes without crowding space.
Is it weatherproof? Look for resin or poly resin construction with UV fade resistance and water-tight seals. Resin options typically resist moisture and sun exposure well, reducing maintenance.
Do you need dual use? If seating or table functionality matters, benches like the 150-gallon Westwood offer integrated seating. For purely storage, prioritize capacity and lid security.
Security features: Some boxes offer lockable lids or space for external locks. If you store valuable items, prefer units with lockable access or compatibility with padlocks.
Mobility and setup: Heavier boxes may require a larger footprint and easier-lift mechanisms. If you move items seasonally, favor lighter designs or those with handles and wheels (where applicable).
