The challenge with carpet in the bathroom is when it comes time to clean, all cleaners have chemicals in them that carpets hate!  There are lots of other reasons not to have carpet in the bathroom (besides how warm your feet stay!) but that’s for another time.  See what happens when the toilet cleaner misses the bowl:

Couple more days of walking on and you won’t even be able to see the patch!  Next time maybe put some plastic down?
