This little "plant shelf" has dimensions of about 51" x 53" (the sides that touch the wall, not the diagonal part of the triangle).

You can see they originally put drywall and it was not strong enough. I want to put a type of wood that I can paint right over. OSB isn't good enough and I don't think any type of plywood would look good, either. I would like to have done this in one piece, but since the sides are both >4ft., I don't think that's possible.

It's above this closet where the blue arrow points to.

I would use medium density overlay, or MDO. It is plywood with a paper face that is used for exterior signs, it paints perfectly and is water resistant. If you left a piece outside for 5 years it would still look like new.

Ok. Thanks.

Any suggestion on how to hide the joint? I will have to use 2 pieces here.

If there is hollow space below it you could glue and clamp a piece on the bottom of the joint before installing it.

But what about looking at it from the top?

Piece of L-shaped molding on the corner?

Or are you saying you want to cover a butt joint?

If you have wood flooring upstairs, maybe use the same? Just throwin that out there.

Plywood, then waterproof and tile - trim the front edge with wood to match the lower room, etc.

Could be a scrap of granite and skip the plywood if your wallet can support that! Front edge would be rounded or whatever shape you wish.
