A 6.5 gallon electric shower tank — more capacity than the Pro tank, with an electric pump rather than manual pressurising.

The pump is the whole difference, and it is worth the money to anyone who showers more than occasionally. Constant pressure, no pumping between rinses, and it draws down the full tank rather than losing pressure as the level drops.

6.5 gallons is a genuine multi-day supply for two people.

It needs 12V power, so factor in how you will wire it. Mounting is not included — tell us your rack or bed setup and we will help you sort it.
