Solar shower in the Northwest? Isn't it too cold? Apparently not.
I picked up a $12 shower from the boat store and have been experimenting with it over the summer. I like it a lot. It takes a good 5-6 Pacific Northwest summer sun hours to make it warm enough to use but it works. This one holds about 2.5 gallons of water, which is enough for me (I usually have quite a bit extra).
The wife says it's not enough to wash her hair, but she does like it because the temperature stays constant throughout the shower, unlike our normal shower (so far), which seems to be either too hot or too cold, hard to get just right. I think we'll be able to fix that soon - it might just be a matter of leaving the hot water heater on for awhile before the shower. Until then, solar it is!
