Most of the parts are metal. Looked great. One day the plumber installed faucet..same day called about a leak around sink drain flange. Pipe attached to sink flange is PLASTIC..when tightened enough to try to stop leak around sink flange, plastic threads do not hold. Also the clevis strap that attaches to pop-up drain plug is PLASTIC...again because of PLASTIC the lock nut would not tighten enough to lift rod.
Plumber had to come next day and put in replacement parts that were METAL to do the job. Of course the drain plug and sink flange do not match the faucet. Why use plastic on functional parts?????
