MikeAqua: Joinery: Make sure any laminate is fully sealed - especially along the botom edges of the cupboards draws etc. exposed fiberboard can absorb water and blow out. Avoid fibre-board window mouldings near work surfaces in the kitchen for the same reason. They can blow out in time unless sealed very well on all edges (which builders almost never do).
I'd go as far as specifying that all MDF will have a water resistant glue. I've used this in a bathroom cabinet, left a sample outside in the rain and it took a very long time to start to puff up. Much better than standard MDF.
