This place is fantastic. What a hidden Vegas gem. I've lived here all my life but I never would have known about Imperial Spa if not for their deal on Living Social. If you can catch it, the deal is $20 for two passes (regular price is $20 each), so bring a friend (or use it twice)!
My favorite was the dry salt sauna room. It was warm but not too hot and there are big mats for your to lay down on. I stayed in there for about twenty minutes and was completely relaxed. Be sure to wear slippers in here (you can bring your own or get a pair at the front desk in exchange for your I.d.), the tile floors get really hot.
I also really enjoyed the ice room. It was such a relief after being in some of the hotter rooms. The cool marble felt amazing against my skin and there is a little section of cold stones you can stick your feet in.
I did not like the red clay ball room as much as I thought I would. This room has big tubs which you can lay down in full of tiny red clay balls. I imagined getting down in the balls and relaxing that way but they were way way too hot for that. I was able to get in there for a few minutes by laying a towel down on top of the balls but anywhere they touched my skin was almost unbearable.
I ate lunch in the little cafe and it was pretty tasty. It was pricy but you get a lot of food for the money. A friend and I split the chow mein and we couldn't even finish it was so much food! After lunch we relaxed for a while and watched tv in the lounge area on the second floor while sipping iced green tea before getting back to the spa time.
I will definitely be going back again. I left feeling completely refreshed.
