just changing my doors in my house to flush fire doors, mainly just so the doors have a more solid feel than the hollow plywood doors that were on before. Anyhow I have a 2 foot wide airing cupboard and was going to change that too, to a flush door. I have a 2 foot 6 inch width plywood hollow door which I've changed and was wondering about using that on the airing cupboard? It would mean cutting 6 inch of the width and then fixing a new edge rail to it? Is it going to fall apart, is it worth the hassle?
