I have things a little different. I am in cubicle world and have a heater under my desk so after arrival at work I get cleaned by using a face cloth and small hand towel, soap and water. I also wash my hair in the sink. When I am done cleaning up no one can tell I have been in that bathroom. I take my riding clothes and hang them under my desk for an hour using the heater to help any wetness dry. Then I put everything back in my pannier. I do not get very hot riding in to work so my clothes is not soaking wet. That is how I handle the situation.
