Do you prefer your water bottle to be made of metal, plastic, glass, or something else? Straw or no straw? How big would you want it? Should the bottle taper down in the bottom, or do you think the sided should stay vertical? Are any of you one of the few people who would like that weird rectangular bottle? Or maybe one of those squishy fold up ones for travel? No handle, flip up handle, mug style handle, or little loop?

Can’t you just fill it from the tap?
The bottles were filled from the tap. But this meant I had cold, convenient water I could just grab a drink when I was thirsty.
Also, having items in a fridge makes the fridge more energy efficient.
