All the time! Beds are always hotter here. Also the running water from the overhead tanks is so hot that it can burn your skin. With the India style bathrooms, you can imagine the horror.
For the rest, In Indian style toilets, you don't wipe your ass, you splash it clean either with a water jet or your hands. So hot water .....
It may be a good idea to paint the outside of the rooftop water tank with white reflective paint.
