It gets down right cold and it is tuff to keep our bottle water from becoming freezing cold. So, I came up with the idea of using my daughter’s sweatshirts aka hoodie. It won’t keep the bottles from freezing in my neck of the woods; but I am hoping it will help others that are on cusp of freezing weather.
Also if you are tired of looking at a typical water cooler - add a hoodie.
I not sure what is the standard size, but we receive 5 gallon bottles for our cooler, it actually we use it as a dispenser - we are not into really cold water.
It is approximately 11 inches in diameter and 20 inches tall.
