Was looking to upgrade shower heads and kitchen faucet. looked around and finally settled on massage shower heads from alsons for about $25 each. Then went ahead and got this sink faucet with sprayer from kohler for about $75. I talked to one of their plumbing experts, just to make sure I had everything I needed for install. I ended up getting some plumbing tape/seal, and some silicone to caulk. Overall install was a breeze, just as instructions, and did not need to use silicone, everything sealed pretty well, did use the tape on the shower heads.
