Hi- I'm finally getting around to installing sliding doors in the utility room- bought a Slik 1828mm runner kit to hang the doors which will need cut, and am planning to use B&Q's most basic veneer doors (35mmthick, 1981mm high and 838mm wide). At this width would a 38mm overlap be enough? It's only for a storage cupboard and obviously gives me a neat internal finished width of 1600mm to work with? Or is this too little? I've got the runner so can work out the distance from the where the door tops will be to the top of the runner so can crack on with the frame once a few calculations are done(!) and get the doors after xmas....
