Check out these pictures from roopurt (of FetLife) who built a jail cell in his basement, complete with a toilet, shower fixtures and even an under-the-floor cage! He posted more about this impressive do-it-yourself project on Reddit
Reddit post is available here.
Metal would like to thank roopurt for sharing these pictures, which are posted here with his permission.
Well done!!! You should be proud of the result from all the sweat equity you and your friends put into that space. Congrats!
I want to be thrown in there.
Wish I was able to be locked in one I never will be able to afford to build one being disables
