Hmmm,
Yet again I run into a post that discusses something I'd love to do. I guess all woodworkers are alike on some level - one being that they see wood being able to serve any purpose (let's not forget that the first cars used wood frames!).
I did some research since seeing this thread and thought I'd share a couple things:
- this URL is from a wood top manufacturer and it discusses their finishes of choice (Waterlox is one of them):
http://antiquewoodworks.com/wood-countertop-finishes.shtml
- sink areas can be constructed with a more water tolerant species or material. If working with a home shop machinable material you can run some slots into the top that descend into the sink, helping to avoid the water pooling issue. Heck, you could even machine a whole region around the sink to taper into it so that water won't be an issue. In my own ideation I've considered finding a suitably sized antique porcelain sink with integral side washboards, to lay on top of the wood. Metal sheeting and concrete are other ideas for around the sink (or stove). I would also think you could use a plastic film finish like epoxy or polyurethane, just around the sink, in order to give it that additional protection, if so desired.
- stainless steel (or possibly aluminum) strips, grids or plates can be embedded into the wood surface to create 'hot plate' spots. They can be permanently installed or be removable. Copper and bronze may (will?) stain the wood they're attached to.
- I would think it might help to fill pores, in a VERY open grained wood like oak, using an epoxy or acrylic filler, prior to top coat?
- IKEA apparently sells wood counter tops (red oak)
- I like this FAQ page:

- granite is probably less 'food safe' as it is not NSF or FDA approved for professional food handling. Certain wood species with certain finishes do receive NSF certification.
