"I like everything in your house."
Translation:J'aime tout dans ta maison.
Tous is plural, tout is singular, but for the use you're going to need someone better at French to answer. .
I think it's something like:
Tout (by itself) = abstract concept of "everything"
With other words, it has to start getting conjugated:
Tout le monde = everyone
Toute la journée = all day
Tous mes amies = all my friends (mixed gender/male)
Toutes mes amies = all my friends (female only)
