I don't like the pine and would cover/paint if I could and I wouldn't use oak on the top. What about granite, though? You could get 8-9' remnants in any one type of granite and put them there (the fabricator would do the install).

What's underneath this ledge? It's got to be there for a reason.

Thanks for the feedback. This is a split-level home, and the ledge wall is covering the foundation wall and electric running to outlets in the wall, so it has to stay! I don't like the pine either, so my original plan was to paint it. Just struggling with color choices too. The granite is an interesting idea for the top. I hadn't thought of that, but will definitely look into it! Thanks for the suggestion!

I've never worked with MDF, but something else to look into as well and cost effective. Thank you!

Paint the pine the same color as the walls. Since the ledge is 10 inches wide, it could attract cups and glasses. You can paint it the same color as the wall with best semi-gloss enamel or you can add something fairly waterproof such as whatever surface your mini-kitchen countertops will have. The latter is more of a design statement for the ledge. The former is unobtrusive.

Good point on attracting cups, etc! I'm starting to like the idea of the ledge blending in more and not being the main thing you see in the room. Thank you!

If you use MDF and paint it, cap the edge with something that will give you a bit of a profile, a little visual interest. If you use granite, don't go overboard, just something calm that provides a little color.

What would you suggest as a cap for MDF?
