My bathroom sink takes several minutes to start pulling hot water. I feel like I’m wasting a lot of water, but I also despise washing my face with cold water right before bed. Is this a problem a plumber can fix?
Yes, you can have a recirculating pump installed for instant hot water and little to no wasted water.
Another option would be to install a tankless hot water heater. An added benefit is that they are very energy efficient.
