I used to live in a place with a horrible shower. The room the shower was in would be aruond 3C cold in the winter time and the water only lasted a couple of minutes, before that too got freezing cold. So, if I had to pick between using that shower, or going to the gym/pool where they had nice showers and a sauna...the latter usually won out. And once I was there, I of course, exercied/swam every time.
