John, It sounds like your shower is too large for the current circuit it is on. That size of shower would need to go on 10mm Twin+ Earth cable with a 45a mcb and would now have to have a RCD fitted so you have to alter/upgrade the current consumer unit. You can run the cable in white trunking so yeah its possible. Post the job on the man section of the site and an electrician local to you should get in touch to discuss Thanks Russ
