A linear foot is measured at the base of the total number of cabinets, both those installed on the floor and those mounted above the countertops. For example, if you have three sets of 36-inch cabinets on each side of the sink, a 24-inch cabinet above the sink and the cook top, plus a 36-inch cabinet over the refrigerator, this is a total of 16 linear feet. The sides of the cabinet are not included in the measurement. Just the measurement along the bottom of the lower and upper cabinets is included.
A 24-inch cabinet costs less than a 36-inch cabinet of the same materials because less materials and construction time are used to produce the 24-inch cabinet. Plywood with a hardwood veneer costs less than all hardwood construction. Custom cabinets made to your specifications in terms of size and materials cost more than cabinets made for purchase off the rack. These variances affect the cost of the required linear feet for the project.
Cabinets are priced per box unit. The same size cabinet can vary based on whether it's made from pressed wood with a veneer, such as those found in garages and storage areas, or hardwood, typical of kitchen cabinets. The box unit cost most likely does not include installation and may not even include assembly costs.
The project cost for cabinetry and storage in a master bedroom closet will be based on the components, quality and installation. Some do-it-yourself closet organizers are made for ease of installation by the homeowner. However, it's common for a kitchen renovation project to be based on the linear footage of the cabinets and include the cost of the cabinets, tearing out the old cabinets, preparation and installation of the new cabinets. When comparing costs, make sure you're comparing the same costs across bids.
If you can't afford to replace the cabinets, consider refacing them. The old cabinet doors and drawers can be removed and new ones installed. This gives you options to change the style of your kitchen or bathroom within certain limits. Refacing is based on the linear footage of the total cabinets. Refinished cabinets are another option. Pricing is based on the linear footage if you're hiring the project out. Finally, there is the option of gluing veneer to the cabinets. This cost is less than refacing but more than refinishing.
