I've spent the last year or two thinking about a robe warmer and kept coming up with ideas that would look awkward or cost too much. I tried searching all over the internet and tons of people wanted one but very few ever built anything. Looked on Amazon as well and most were either really sketchy with terrible reviews or extremely expensive. I was really shocked by how many just put their towels in the dryer and then rolled them up in a cooler. I'm sure the cooler concept would work but this posed two problems for me... First, it meant I had to walk outside in the cold with nothing on and it also meant I had to "pregame" just to use my hot tub which would ultimately lead to a massive decline in use.
So I came up with this concept. It uses a single 4x8 sheet of plywood coated in waterseal. The size is 48x16x24 inches. I also used a 1x4 around the lid and some 2x2's on the inside. A basic space heater with thermostat keeps it nice and toasty inside and the pvc coated hardware wire keeps everything away from the heat source. I originally wanted an electric timer but opted for a wireless remote which I can turn on and off as needed. The timers are either expensive plug in versions or wall mounted which requires running dedicated electrical lines and I wanted to bring this box inside in the summer when I won't use it.
Total price was this:
4x8 plywood - $19
1x4 board - $3
2x2 board - $3
Remote switch from Amazon - $10
Extension cord to run to the box - $20
PVC coated Hardware cloth - $8
Hinges - $6
Screws - $6
Space Heater - $15
Waterseal - ? (Have had this stuff laying around my house for years)
Total - $90 (I probably only spent about $50 as I had a lot of this stuff laying around)
Hope this helps others who want a toasty robe on a cold night...
