IMO, go with solid. I don't mean to knock masonite down but because i have no experience with that material as a door, and that that i grew up with solid hardwood doors and had no problems with them thus i'm bias. Solid hardwood doors is the way to go.

Google Masonite doors with the word 'reviews' and see what you can find. People wil tell you what they love and hate about a product.

If you are okay w/ the added cost of solid doors over hollow core, by all means, go w/ solid. I have had plenty of issues w/ hollow doors, especially the bi-fold closet doors. Not only do they tend to break, the doors are almost all made entirely of glued up MDF-like material, which makes it almost impossible to screw anything securely into them (i.e. hinges, hooks) or rip to slightly smaller size. I have seen countless holes punched into them from door stops as well.

Masonite doors come with at least 3 options for stiles and rails, at least 4 options for core material, and several different skins. Don't compare the cheapest to the most expensive. Traditional solid wood doors are prone to warping and shrinking joints. Several combinations of Masonite door construction are more stable. Most builders don't get the full MDF doors you see at the big box store. They get them with wood stiles, and even in a fire rated door to match for the garage to house passage door. Door stops should not be busting through hollow core doors unless the installer hasn't even passed bumper installations 101.

I think that wood doors are going to be a better sound insulator than a hollow door. I would go with solid wood.

For sound, the particle board core and mc cores are better than most wood doors. The mistake people make is thinking that Masonite doors are those cheap hollow cores at the discount store.

Fred S. I stand corrected. I was referring to the cheap version of Masonite doors from the big box stores. I do not install doors really, but have used on a few occasions those types, as well as dealt w/ existing doors in customer's homes, all of which, were as I described before.

we are doing a remodel in Florida and settled on solid core Masonite for interior doors.

Are the Masonite solid core wood doors good for staining? I'm in Florida so worry about the warping in a solid wood door, so hope that the Masonite solid core wood doors will work.
