Tiny Watts 3 in 1: Power System + Water System + Bed Platform


Vehicle Type
Dimensions & Side

This is the whole enchilada people! The Tiny Watts 3 in 1 kit is a plug-and-play power system on one side of your van and a pre-plumbed water system in matching enclosure on the other side, which together form the base for a bed platform. Two of the most complicated systems for your van build (electrical & plumbing) built by professionals drop-in and ready to go. Once it's installed you're ready to go use your van! Figure out the cabinets & galley later!

Plug a fridge directly into the power system 12V socket to have refrigeration, plug a portable induction cooktop into the power system for cooking, charge your devices with a USB socket on your power system, take a shower to get clean with your water system's built-in outdoor shower extension, and have a place to sleep. A skilled DIYer can get both these systems installed in one week so you can get out there and use your van faster!
