I am about to tile my bathroom floor so putting 9mm ply plus tile on top of that so say 20mm increase in floor height, I will require to trim the bathroom door to allow for this. The doors are cheapy doors with a cardboard internal, what is the best way to trim the so that I get a neat edge, last time I tried this I got a kindof ragged edge and it was obvious it had been trimmed.
Any help appreciated.
