Why does it take so long for hot water to reach distant bathrooms?

“When I turn on recirculation in the app, wait a few minutes and then turn on the hot water in the shower, it takes at least 2 minutes for it to be comfortable enough to go in.”source ↗
“When I then I wait a few minutes and turn the hot water on in the shower, its still like 2 minutes.”source ↗
“got the same setup, the bluetooth button is basically useless if your bathroom is on the other side of the house.”source ↗
“Shower takes 30-40 seconds to get hot, so not ideal. With how much life this has left, is it worth the price to replace if I only plan on living here for a few more years?”source ↗
