I think this faucet should be listed as "Monitor 17 Series Pressure Balance Shower trim kit" because it does not come with the valve to operate the faucet. Most  listings do state when it's a trim kit only. I did not realize until I got it that it didn't have the most important part to install this faucet. The cost was quite expensive to say I had to order a $60.00 part to work it. This is my first issue ever using Wayfair. I will continue to use it because it has served me well on every order up to this point. I did call to tell the representative the issue I had with this particular purchase. Hopefully, it is something that can be fixed so that others don't end up in the predicament that I had found myself in.
