Hi there Esther. You will require the skills of an experienced plumber for this. A cold mains supply pipe and a waste pipe is needed. These can either be ran from behind your kitchen/work top units or on top off or secured to wall/tile, this all depends on the installation, either domestic or commercial premises, and so there are different materials for this, unfortunately that is all the information we can provide at JIRELAND PLUMBER, due not being able to see the job in person. I hope this helps. JIRELAND PLUMBER
