How many people live in a house like this?

After another awful day at work, a terrible journey to Suffolk and pouring scolding hot soup on the only pair of trousers I have bought away with me I was glad to come to bed tonight to get this day over with and start a fresh tomorrow.
One thing did make me smile though. These toothbrushes., can you guess how many people live in this house?
Answer 2
Our toothbrushes are not even in there yet I think somone has a fetish ;).
