Best way to protect bottom of bathroom door from steam after trimming?

[john2k]

My bathroom door is a solid fire door with an oak-effect laminate finish. Because of bathroom steam over the past 10+ years, the laminate at the very bottom edge (inside bathroom side) has started lifting and feathering very slightly.

I’ve recently laid new flooring which has raised the finished floor height, so I need to plane quite a bit off the bottom of the door anyway, which should remove the damaged part.

Once I’ve trimmed it, I’m wondering what the best way is to stop the bottom edge from getting damaged again from steam and moisture in the future.

Any recommendations of what I can do to protect the bottom of the door after trimming it? Strangely the top of the door hasn't had this issue, wondering why it only happened to the bottom.

Thank you

Probably happened at the bottom due to hot moist air conensing on colder surface at the bottom. Just smear some silicon over the cut edge and allow to dry before re-hanging the door

Get a more powerful extractor fan, and use it more often.

A "silent" one, coming on with the light switch and having a timed overrun, is most effective. Electricity usage is negligible.

You are not "allowed" to trim the tops of fire doors, where the certification is printed, but you are "allowed" to trim the other edges a bit, so I expect yours has a raw edge.

People painting doors never paint the bottom, and seldom paint the top as it is out of sight.

These are the surfaces most prone to damp penetration on external doors, so I make a special effort on mine.

Bathrooms don't need fire doors to perform as fire doors.

If its oil finish, use a quality oil and several coats to let it soak in.

If painted, use a polyurethane varnish, 2 or 3 coats. A trick which may help prevent edge splinters is to run a thin bead of superglue along the edge of the ply veneer

I didn't say they did.
