When you have a bowel movement followed by a shower, the smell combines with the steam creating a poo sauna.

When you go to have a shower in your bathroom but while you wait for it to warm up you use the toilet. Whilst you squeeze one out on the toilet, the shower creates steam within the bathroom giving you the effect of having a poo in a sauna. Sometimes this can cause poo sweats.
