Outdoor water storage is it possible outside of BC?

Both are great ideas. The only issue with the insulation/heater idea is if he will be using an RO unit. Theres not much that can keep that from freezing. And with the tiny lines it will be the first thing to freeze.

Making a shed is costly, and heating it is even more so. If you can easily manage something like Steve suggested, then that is your best option to tie it to the house.

I vote making a table disguise out of wood and hiding everything underneath. You could make a cool bar or something on top to make it even more enjoyable.
