BYOC Rules
Before you start thinking about filling up a bath tub, there are three rules to follow:
Confirm the cup is watertight. Fill it with water first to check for any leaks.
Make sure your cup is clean. Give it a good wash before heading to the convenience store.
Verify the cup fits upright within a 10-inch diameter hole. You can double-check your container’s workability via an in-store display. (If it doesn’t, it’s a no-go.)
There are more than 13,000 locations across North America, so odds are one is close to your home, work or school.
