For the cabinet box, plywood performs significantly better than particleboard near moisture. Particleboard can swell and soften if water gets into the seams or base. For door surfaces, thermofoil can peel at the edges over time when exposed to heat or steam near the stove. A quality lacquer or painted finish on HDF or solid wood holds up better in high-heat and high-moisture zones than standard MDF or thermofoil. Avoid particleboard boxes and thermofoil doors in the cabinet run immediately adjacent to the stove or sink.

Areas near the sink and stove are some of the hardest-working zones in the kitchen, so materials matter even more there.

For cabinet boxes, plywood is usually the stronger choice because it handles moisture better than particleboard. Particleboard can swell and soften if water gets into the seams or base, which is a real risk near sinks where slow leaks sometimes go unnoticed. That’s especially important near the sink, where splashes, leaks, and humidity are harder to avoid over time.

For doors and exposed surfaces near the stove, thermofoil should generally be avoided—it can peel at the edges when exposed to repeated heat or steam. A quality lacquer or painted finish on solid MDF or wood holds up better in high-heat zones.

For cabinets in both high-moisture and high-heat zones, HDF (High-Density Fiberboard) is an excellent material choice. HDF is more moisture-resistant than standard MDF, more heat-resistant than thermofoil, and more durable under impact than either. If your kitchen has cabinets positioned immediately adjacent to the sink and stove—a common situation where both moisture and heat are challenges—specifying HDF doors and plywood boxes in those areas will significantly improve long-term performance. While it costs more than standard MDF or particleboard, the durability gains are especially worthwhile in zones that will see the most wear.

It also helps to think about small protective details, like under-sink liners or extra sealing inside the sink cabinet. Those choices may not be visible, but they can make a real difference in long-term durability.
