StormBag SB010 vs SB025: Which Size Do I Need?
StormBag sells in two consumer-scale pack sizes and one bulk case: SB010 (10-pack), SB025 (25-pack), and a SB-BULK-250 (250-bag bulk case) for facilities and heavy users. This guide covers what each pack covers, when to pick each, and how to think about combining sizes.
What's the difference between SB010 and SB025?
Only the pack count and price. Each StormBag inside is identical — same 1 lb dry weight, same 30 to 35 lb hydrated weight, same polymer core, same 5-year shelf life. The SB010 is $99.99 for 10 bags. The SB025 is $239.99 for 25 bags. On a per-bag basis, SB025 is roughly 4 percent cheaper than SB010.
Which size do I need for a single door or entry?
The SB010 (10-pack) is the right choice for a single doorway or single window well. Ten hydrated bags cover roughly a 5-foot-wide, 12-inch-tall barrier with proper brick stacking. For a standard 36-inch exterior door, ten bags gives you enough coverage plus 3 to 4 extra bags for the corners or a small ground-level window nearby.
When should I buy the SB025 (25-pack)?
Buy the SB025 when you need to cover:
- A full home perimeter (front, back, and one side)
- A garage door plus adjacent openings
- Two or more entries at 12-inch barrier height
- Any single opening where you want a 24-inch barrier (double-stacked)
Twenty-five bags is also the typical starter kit for a Gulf or Atlantic coast homeowner who wants full-home coverage before hurricane season.
When do I need the bulk case?
The SB-BULK-250 case is for facilities, contractors, and heavy users:
- Multi-building sites (schools, warehouses, small industrial)
- Municipal emergency inventories
- Property managers with 10+ residential units
- SWPPP compliance for construction sites
Bulk pricing is significantly lower per bag than consumer packs, and the case is designed for palletized delivery and long-term flat storage.
Should I mix pack sizes?
Yes, if it fits your deployment plan. A common combination is one SB025 for the home perimeter plus one SB010 stored at a secondary location (rental property, vacation home, or garage in another state). This gives you geographic coverage without over-buying.
