Some people have really nice toilets at home, that will wash their behind. Not many offices have ones that do that. So you end up sitting in your own excrement for 8 hours.
The life style bump up from that, is worth it.
The one office where I worked, it was always locked and logged with an access card. So I never tended to use it as often. Vs now I can take a shower at home any time I want to.
