A bottom loading water cooler hides the 5 gallon bottle in the cabinet below, so you do not have to lift it over your head. That is the main reason people choose one. The other choices are temperature settings, whether the unit can clean itself and how much room it takes.
The six dispensers below are mostly bottom loaders from the Primo, Brio and Avalon families, plus one top loader for comparison. Details come from the product listings, and we have not used these coolers ourselves. Check bottle size, power and safety notes on the product page.

Bottom Loading or Top Loading?
| Type | Good at | Watch out for |
|---|---|---|
| Bottom loading | No lifting; the bottle is hidden | Taller cabinet; a pump moves the water |

Water Cooler FAQ
How often should I clean it?
Follow the maker’s schedule. Self-cleaning features do not replace regular cleaning.
What size bottle do these use?
Listings say 5 gallon bottles. Confirm on the product page.
Do these need a plumbing line?
No, bottle-fed models only need a power outlet.
The Short Version
For three temperatures and self-cleaning, the Primo 3 Temp or the Avalon A3BLK. For hot and cold with a simple setup, the Primo 2 Temp. For a self-cleaning Brio, the 520 Series. For a basic top loader, the Brio 130.
