Even though laminate cabinet doors are almost the cheapest selection for your cupboards, they are far from being the lowest in quality. When speaking from a standpoint of durability, I think high-pressure plastic laminate doors are the most durable of all.
Now I’ve been in the kitchen cabinet manufacturing business for many years and have owned several companies related to the industry. I’ve seen my share of old Formica cupboards that were in excellent shape. I have also seen some that were not in such good condition. Just like anything else, when something is maintained correctly, it’s possible “that” something will last a lifetime.
Laminate doors will last thirty to fifty years. The only thing that is required of the owners is to keep them wiped down regularly. Formica doors are easily cleaned with Windex, Formula 409 or just a damp cloth.
If you are considering having Formica in your kitchen or bathroom, may I suggest that you select white or off white for the color. Through the years these two colors have long withstood the ever changing kitchen cupboard trends. Many different shades and patterns of laminate get discontinued every year, but white remains on the color chip chains of all the suppliers.
