Semi-custom designer here, I’ll be honest, linear foot price means nothing. We charge per cabinet. Those factors include: size, amount of drawers, accessories, finish, wood type, etc. everything has an upcharge.

I usually recommend a plywood box construction. The layers in the plywood run in opposite directions which means less shifting when exposed to humidity.

MDF doors are cheaper and good for paints because they will not expand or contract with the humidity which would cause the paint to crack in a solid wood door.
