Sauna Poo 

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.

Sorry I'm late, went for a shower but then treated myself too a sauna poo!

Pooh Sauna 

A pooh sauna is created when someone first visits the toilet for a rather pungent smelling deposit, and then activates and uses the shower. As a result, the pungent smell is heated by the steam from the shower, thus creating a 'pooh sauna' for the next unfortunate entrant to the bathroom.

Jesus mate you've just created a horiffic pooh sauna in there!
