You would think that for $150 you are getting something that won_ work or is really poorly constructed. This unit is not that. It does work. The controller unit is extremely ugly and given it is not waterproof, you can_ control the steam bath from within the shower. As some other have pointed out, I mounted mine inside the vanity cabinet. Others have stated the controller is only in centigrade. Mine is in Fahrenheit.The unit does not put out the volume of steam I_e seen in a more expensive unit I had in my old house. It puts out plenty of very moist and very hot air. There is some stream but just not as much as I expected.One other thing is the temp sensor is kinda short for mounting behind the tile. You could mount it on the surface of the tile but the mounting plate is rather ugly. I put a hole in the tile and then ground out an area in the back of the tile so that the sensor would stick through the surface. The sensor is then set in the mortar along with the tile. Worked fine.All in all this is a decent unit for the money.
