Those kitchen or bathroom cabinets look great on the outside, but what about their inner structures? Does it matter whether they are made of particle board or plywood?
On the whole, kitchen and bathroom cabinet boxes entirely constructed of plywood are sturdier, more durable, and hold veneer better than particle board cabinet boxes. If all other factors are equal, plywood cabinets are best. But considering other factors such as cost and availability, particle board cabinet boxes can be a wise choice.
Cabinet Construction—Boxes and Fronts
Kitchen and bathroom cabinets can be divided into two elements: boxes and fronts. For example, a kitchen cabinet base with no doors, fixtures, or countertop is a box. A kitchen wall cabinet (the type of cabinet that hangs from the wall) devoid of fixtures and doors is also a box.
Fronts are an entirely different matter. Doors and drawer fronts are the veneered decorative face that you see, the part that most people are concerned with. Common front styles are Shaker and slab and popular veneered wood species are cherry or oak. Below this hardwood veneer front is a plywood base. The other interchangeable elements are the decorative veneered side panels, which typically match the veneered fronts. For framed cabinets, the exposed vertical stiles (vertical sections) and rails (horizontal sections) may be veneered or may be solid hardwood.
Boxes are the true heart of cabinet systems. Boxes, too, are interchangeable. A cabinet manufacturer may, for example, offer only one 36 inch base cabinet. But according to your design wishes, any number of door and drawer fronts may be attached to this one base cabinet.
Particle Board vs. Plywood
Cabinet boxes are structural, and thus need to be strong. And this is where particle board and plywood come into play. Particle board, also called medium-density fiberboard (MDF), will be stable as long as it remains dry and is not subjected to undue stress. As long as it remains veneered, either with wood or thermofoil, it can perform well for many years to come. MDF often goes by different names, such as composite wood, fiberboard, or by the brand name Masonite.
The type of plywood used for cabinets is not the cheap plywood used for sheathing and construction projects. Cabinet-grade plywood often has twice the number of plies, better lamination, and a smoother finish. It cuts cleanly, with little splintering or damage. Cabinet-grade plywood tends to be 3/4-inch thick and may be veneered on one side with inexpensive wood, such as birch. Plywood cabinet boxes are lighter than particle board boxes. This makes them easier to install for wall cabinets, where high lifting is required.
Cabinet Costs and Availability
Generally, cabinets made from particle board will be cheaper than those made with plywood. Because particle board is cheaper to manufacture, cabinet boxes made from this material tend to be about one-third cheaper than plywood boxes.
Particle board boxes are slightly more available since these tend to be the off-the-shelf cabinets found at Lowe's, Home Depot, and IKEA. In most areas, it is difficult to find plywood cabinet boxes that you can purchase and bring home the same day. Should you need to reface your cabinets later on, plywood cabinets are better candidates for refacing than particle board cabinets.
Manufacturers and Retailers
The following ready to assemble (RTA) companies use only plywood for cabinet boxes. Plywood boxes often have shelves that are thicker than the sides. Be sure to check manufacturer specifications to make sure that they are using all plywood.
- RTA Cabinet Store
- The RTA Store
- Kitchen Cabinet Kings
- IKEA: IKEA's commitment to MDF cabinet boxes is one way it keeps its products so cheap. None of IKEA's cabinets are made of plywood.
- Home Depot, In-Stock: Both the inexpensive, generic in-stock cabinet boxes and Hampton Bay branded cabinet boxes are all made of MDF.
- Lowe's, In-Stock: Its house brand, Kitchen Classics, uses particle board for cabinet boxes.
- Kraftmaid: This popular cabinet company liberally uses MDF for cabinet boxes, but it does have an option for all plywood construction as an upgrade for an extra cost.
- 27Estore: This Las Vegas-based online retailer of Euro-styled cabinets uses MDF for its boxes, though it does have an extra cost upgrade for birch plywood.
