Which plywood is best for kitchen cabinets is one of the highest-stakes material decisions in a home, a kitchen sees more daily moisture, heat, and steam than almost any other room, and plywood kitchen cabinets built from the wrong grade show it within a year or two. This guide covers grade selection by cabinet zone, thickness, and where marine plywood actually earns its higher price.
Every other room in a house sees moisture occasionally. A kitchen sees it constantly, steam from cooking, splashing at the sink, condensation from appliances, and spills that are not always wiped up immediately. That is why the standard advice for which plywood is best for kitchen cabinets is more specific than for general furniture: match the grade to the exact zone, not the room as a whole.
A mixed-grade kitchen, marine or BWP near the sink and hob, MR everywhere else, is a common and sensible way to control cost without cutting corners where it actually matters.
Plywood is the stronger structural choice for kitchen cabinet carcasses. For visible shutters and fronts specifically, pre-laminated particle board is also worth considering, it comes finish-ready in a wide colour range, so the decision often becomes plywood for the carcass and structure, laminate or prelam board for the visible finish. See the Pre-Laminated Particle Board Guide for the full colour range and how its pricing compares.
BWP or marine grade for zones near the sink, dishwasher, and hob, where moisture exposure is highest. MR grade is generally sufficient for upper cabinets and areas away from direct splash.
Just the parts. Marine plywood is worth the added cost specifically under the sink and around water-facing appliances. Using it across the entire kitchen is rarely necessary and adds cost without much added benefit in low-moisture zones like upper cabinets.
18mm for carcasses, shutters, and load-bearing shelving. 12mm is acceptable for backs and light internal dividers, but should not go any thinner given the moisture environment.
This depends heavily on kitchen layout and cabinet count, so it is best calculated from your actual cabinet design rather than a general rule. Your dealer or carpenter can provide an exact cutting list once the layout is finalised.
