Nothing is impervious. even if it is, mainly there is a layer/coating act as sealant and exposing to rapid temp. break its bonds. For now go for quartz for top (higher grade / known brand yea. Not cheapo one), solid wood for base. or tiled concrete (the old ways. tile big big lor if want less grout connection 2x2' is sweet spot)

I see a recent trend where sintered stone is used as counter top. Still new i think, not sure how well it lasts. Two of the client has this insists & applied recent years so have to wait and see when she will comeback to me & meroyan about it.
