This toilet model is free to download but you will need to add your own texture to it. It will look much nicer with added textures and will look great in your project so why not give this a download and try it out.
This toilet is sadly not animated so you will need to do this yourself.
This model would also look great in the Sims 3 and Sims 4 and even Garry’s Mod although I am not really a person who can port models into games as I find this difficult at this moment and time.
