This realistic toilet cubicle with toilets, sinks and urinals will look great in any gaming setting but the interior of the toilet will need some modeling and editing as well as the door will need animating.
This is free to download.
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.
