I forgot that the 2014's have the shower run off of the sink faucet. You may can change that if there is access to the shower faucet from under the sink. Installing a single lever shower faucet will most likely be my next bathroom mod.
Here area couple of pics of the sink. It is a Peerless faucet, Model P131LF. Sells for about $30. I don't have any pics of the toilet sprayer handy, but will try and get a couple in the next day or so.
The caulking around the back wall of the lav top is only temp. till I can find some tan or brown caulking.
Not a lot of room up there
