Vaillant Combi Boiler Connection to new Upstairs Bathroom

Hi we have decided to put a small shower room/loo upstairs in our house.
Currently have no water upstairs other than radiators. We have a vailiant combi boiler and my initial thoughts were to T off the 15m pipes in the ground floor bathroom, but then I am wondering if I would be better going from the boiler and using 20m pipe to help with pressure, or would there not be much in it?
any advice would be great cheers
