I’ve mentioned it before in a similar thread, but if you shave your head, get a Pitbull Skullshaver that can be used in the shower or while walking around the house, etc. About $100 and adding it to a shower routine is great.

A wand for the vegetable garden hose. About $70 and much better than a normal gun/nozzle for watering plants at the base if not all of your gardens are raised.

$500ish: 12v car fridge. I use mine camping or on work trips but also at home on mains power as a drinks fridge near the outdoor seating when people are around.
