Which plywood is best?

Marine plywood is the best choice for modular kitchen cabinets as it is rot-resistant, termite-resistant and highly durable, making it the ideal choice for areas where moisture or changes in temperature can affect the integrity of conventional plywood. BWR grade plywood is also a good option for modular kitchen cabinets due to its water-resistance and relative cost-effectiveness.

Depending on your budget and the size of your kitchen, you may also want to consider other types of plywood such as A-grade and C-grade plywood. A-grade plywood is made from hardwoods and provides good strength and stability, while C-grade plywood is the least expensive type of plywood but is not as strong or durable as Marine or BWR grade plywood. Ultimately, it is important to choose the right type of plywood to ensure that your modular kitchen cabinets can stand up to wear and tear and last for many years.
