Where was the bathroom in the conjuring 4 house?

Ok so its like a 4-5 bedroom home and there isnt a bathroom on the first floor. I went to the bathroom in the middle of the movie so maybe we do see one but because the movie was so boring i dedicated my entire viewing experience to finding this mystery bathroom and i literally dont think there is a bathroom on the first floor. And at the start of the movie when the daughter is gifted the mirror the father is says something like "it gets crowded with everyine in one bathroom." I thought he meant like, the bathroom upstairs but there was no room for the bathroom on the first floor so i think they have a home that is a 4-5 bedroom with 1 bathroom and that bathroom is on floor 2.
