We did a gut and remodel on a small kitchen a year and a half ago and spent right around $25k. We purchased IKEA cabinets, but we used a general contractor to do demolition, cabinet assembly and installation, plumbing, electrical, and installing the tile backsplash.
My husband did all the painting himself, and we bought all new appliances.
That budget does not include the price of wood floors, which we installed ourselves across the entire first floor.
