12 mm marine plywood is the thickness most people use for cabinets in a wet room. It is strong enough to build a unit from, light enough to handle on your own, and it will not come apart if water gets to it.
Bathroom vanity units are the most common job. A vanity sits under a basin, takes splashes every day and hides a waste trap that will leak at some point in its life, and a chipboard unit in that position is on borrowed time. The same goes for a kitchen base unit under the sink, which is where most kitchen units fail: it is worth building just that one unit from marine board even if the rest of the run is something cheaper. Beyond that, bath panels and the framing behind them, utility cupboards, boxing in around a shower, and lockers in a boat or camper.
Cutting and handling
One person can manage a sheet at 24.3 kg and two make it easy. It is a dense board, so use a fine toothed blade, keep the good face upwards and let the saw set the pace rather than forcing it through.
Fixing and painting
At 12 mm you can screw into the face confidently and into the edge with a pilot hole first, which is enough for a cabinet opened and closed daily. Seal every cut edge and every screw hole before you fit it. This is the step people skip and it is the one that matters, because water gets into a board through the edges and the holes long before it gets in through a face.
Where not to use it
For hinges carrying a heavy door, go up to the 18 mm board. If weight is the problem rather than strength, the 12 mm okoume board does a similar job about seven kilos lighter in a bigger sheet. And marine bonding is not a licence to leave it unsealed. There is more on sealing and on the two ranges on the marine plywood page and the plywood page.
