We're all guilty of this. Your shower is like your own swimming pool and sometimes the toilet just feels like it's too far away. There's no one around and the evidence will be quickly washed away, so why not conserve more water by peeing in the shower and saving water by not having to flush. Whether you're an environmentalist or you're just lazy, everyone can agree that it's sometimes too cold to get out of the shower to use the toilet. Just keep it to a number one in the shower though...
