A circulation line in a construction like this is probably not energy efficient... You don't just have to keep one pipe warm, but three at the same time. Nowadays, it is common to forgo the “instant warm water” convenience to save energy (which of course means using more water).

I tested it now on a pipe about 6 meters (20 feet) long to the guest bathroom, and it takes quite a while before any warm water comes out.
Then I could have saved the hot water pipes altogether if I only have cold water anyway.
I don’t really find giving up on the "immediate warm water" comfort ideal, especially when I just want to quickly wash my hands—I can’t run 3-4 liters (0.8-1 gallon) of water every time.
Is that really how it’s done nowadays?
Or are there reasonable alternative options?

We didn’t want to give up the convenience of a circulation pump. The pump is scheduled through our air-to-water heat pump system. On weekdays, it runs between 5:30 AM and 7:00 AM in cycles of 5 minutes on and 25 minutes off, then again from 4:30 PM to 7:00 PM. On weekends, it runs from 7:30 AM to 10:00 PM.
If I take a shower outside these times, I know it can take about 20 seconds for the warm water to arrive, so I can plan accordingly.
In my view, this is a good compromise, and the few extra euros per year I pay are worth it for the improved quality of life.

Hello again
Besides the length of the pipe, the sizing is also crucial.
The material only plays a minor role.
For a supply line to the guest bathroom with a composite pipe 16 x 2 mm (5/8 x 1/8 inches) over 7 m (23 ft), that amounts to almost 0.8 liters (0.21 gallons).
It is also important not to forget the supply line from the water heater to the manifold.
