I can't get rid of the sculpting station!

There is also a simple vanilla way to fix the sneak glitch (this won’t help you concerning your main question but thought I’d leave it here anyway): go to edit town, take the teen out, put the teen right back in and return to your game. I think it’s a hard reset like the mod one. Nothing dramatic will happen to your sim when you do that, they’ll just lose their wishes (but new ones will pop up soon enough).

As for the problem with the station I have no solution I fear. The glitch may have occured because there’s a block of wood on it. It’s real strange deleting with testingcheats doesn’t work...
