Yes, it is quite a bit of both of those. Also smelly. In a small room with little ventilation, it will be almost impossible to keep the smell down. I have to have mine in the living room. They are also nocturnal and make lots of noise at night (the sound of the water bottles all night drives me NUTS). I think if you don't have a large room with lots of ventilation it would be a bad idea.
Woops, I also noticed I said the tubs were 24x32. I meant 24x36.
