Our house was built in 2001. We have Moen 4” centerset two-handle bathroom faucets with round, plastic handles (see photo). I’d like to replace the dated faucet handles, but the faucets are still in working order, and as a newbie DIY’er, I am hesitant about creating new problems by replacing the entire faucet. I have been trying to find new metal handles that will fit the existing faucet, but none of the “universal” handles are tall enough. The Moen service center recommended parts 100621 and 100624, but those are priced around $60 per handle. Is there another option for replacing the old plastic handles, or do I just need to replace the entire faucet?
