In Yogyakarta, my homestay had a modern shower with hot water. I was therefore a bit--no, make that incredibly--apprehensive when I found out my new shower was basically a large bucket of cold water and a scoop.
Much to my surprise I adore the bak mandi. It is very refreshing. The trick is to start low (feet and ankles) and work your way up. Bathing in a bak mandi in Indonesia reminds me a bit of playing in a sprinkler on a hot summer day as a child. It's a good thing I like it because it's culturally unacceptable to bathe less than two times a day.
I use the faucet on the left to wash my hair--highest water pressure

Note the pedicure--hello contradiction
