Seriosuly? You are forced to have an outlet in a bathroom? How about those ceiling fan/light combos? You cant have one of those in a shower? Heating the room is not a problem. Im in a climate in the US where I can have my windows open probably 3/4s of the year.
With regards to the room it is a 6.5 x 6.5' square. There is currently one door, a sink, and a toilet against the same wall as the sink. The door is in the wall adjacent to the wall with the sink and toilet on it. The door opens to the left, and the sink is immediately on the right.
My thought is to put a drain right in the middle of the room and add a shower head on the wall opposite the toilet and sink and have it shoot down into the middle of the room. I was thinking to line the walls with cement board, put in a shower pan and then add tile on the walls and ceiling. This is on the ground floor so I would be cutting out the concrete foundation to add the drain Foundation is 6" of concrete.
