I'm posting this per a request from ChunkyMermaid - it was in the background of the cat house posting. I actually built this a few years ago. Inside is an old insulated cooler that plugged into the car - I used it for years when I had to travel for my job and it was close enough to drive. I'm always thirsty, so I always kept coke in it - after I retired it was never used, but we still had it hanging around. I hate to throw away something still useful and we really needed a drink cooler outside. My daughters gave me the Coke tubs underneath.
I built this a little larger than the cooler, so we could store a few extras at one end inside. I drilled a hole through the bottom of the cooler, added a drain and then ran some pipe through the side with an outdoor faucet to drain the water into a bucket after the ice melts. I added the paper towel holder just because it seemed like a handy place to keep the paper towels.
