MDF in bathroom?

I am remodeling a bathroom and want to put bead-board up around the bottom half-ish part of the wall.

I really want to use a wider bead board (2 3/8 inches bead to bead), but while the narrow ones (1 1/4 - 1 5/8 inches bead to bead) are made from real wood (usually poplar), I can only find the wider ones in MDF. Is there a way to prep or seal MDF so that can use it in my bathroom?

narrow=1 1/4 - 1 5/8 inches bead to bead




wider= 2 3/8 inches bead to bead

You mention wider/narrower bead board , dimensions would be more helpful?

dear me! sorry. Here they are (plus now edited into the original)

narrow=1 1/4 - 1 5/8 inches bead to bead
wider= 2 3/8 inches bead to bead

Do you know what type of MDF the Beadboard is made from, overhere you can get MR MDF ( Moisture resistant) and also an external grade. Both of these are OK for use in bathrooms as they won't swell in the humid air but I would not be happy using standard MDF.

The MR usually has a green dye so you can tell the difference.

We can also get MDF beadboard in full 8x4 sheets

I have never heard of MR MDF here. The stuff I have found isn't green though. I will have to go a googling.

MR MDF is in existence and is probably the best choise.

Found the MR MDF!!! We have a company called Nantucket BeadBoard and they have both the MR for bathrooms and the kind for external use as well! Even my contractor is excited. I think we're going to try some of the samples in some very humid, damp, situations next.
