Last house I plumbed for myself, I used 1/4" copper
lines from the water heater to the individual fixtures. It
was no big deal, since there were only three, but the
kitchen was far enough away that it would have taken
a LONG time to get hot water. Sounds like you're
encountering that sort of thing. The lines ran in the basement,
and obviously had plenty of opportunity to cool down.

Later, when I had to rerun that kitchen line for a remodeling
project, I was very careful to put a gentle but steady upward
slope to it as it went towards the kitchen. that way, the warm
water was presented to the fixture.

We never had to wait for hot water at the fixture, and I don't know
which path made the difference, but I certainly remind you that
the bigger the delivery line, the longer it takes to empty its contents.

I've timed it. For each faucet, it takes 3-4 minutes before the water
that comes out is warm.
