Document: We used the Kraus KCV-150 to replace a 20+ year-old undermount sink with three-hole spread faucet configuration. The square vessel sink was a perfect solution to update the bathroom with minimal cost. We placed the Kraus sink over the now empty undermount sink hole and faucet holes to completely cover the old configuration. Added a single-hole hansgrohe faucet and the bathroom was updated with a brand new sink and faucet for $230.
Beautifuly made. Found a nice single-hole Delta faucet to go with it. Looks great in our bathroom remodel. Lots of compliments from friends. Saved a lot of money over other options.
Answer: no
