Making an interior door
We have a funny little closet near the front entry that houses our hot water heater and utility shut-offs. The door is about 60" wide and 60" tall and is currently a flimsy bi-fold door that doesn't close flat - it bows in in the middle at the hinge. The opening is framed and has trim, too.
I was thinking of replacing it with a slab door to make it blend in better, but of course they don't come in this size, so I would have to build it. What materials would you suggest? Obviously it's rather wider and shorter than a regular door, so a lighter weight would be good. Could I make a frame with 1x2's with a cross brace across the diagonal, then face it with masonite (to be painted to match the wall) and use plywood on the back? I just want a nice flat smooth door that blends with the wall better.
In fact, I'd prefer to make it "disappear" - any suggestions on that - if I remove the trim from the front face and paint up to the edge...
