In one of our past homes, we had one section next to the stove that was butcher block, but the rest reg. There is def upkeep to one & doing a small section is much easier than a whole top. Wilson Art & Formica have some really great new laminate choices---for example, if you like granite look, you can get it with these but a matte finish which reads better in a country kitchen.

I think your benchtop material choice really depends on how both you and your husband live and what level of natural wear you are comfortable with showing. Natural wood benchtops to me are very similar to natural stone or stainless steel. The surfaces will naturally age and show use, scratches and imperfections much more than say a caesarstone if it's a high use area but some people love that look and it goes well with an industrial or natural style. My wife and I thought long and hard about it but realised we want the benchtop to look as new and clean each time as possible so opted back for caeserstone (Ocean Foam) which hid small stains and dust :)

My son used to help me cook in the kitchen - he is 190 cm, I am 175cm. I have an old-fashioned breakfast bar which is raised above the level of the kitchen benchtop. My son would stand at the raised section, I would stand at the lower section, it worked really well. An alternative might be to have a pull out step in the kick board spaces for your wife to stand on - I don't know if it would be high enough, but it might make things more comfortable. Speaking from the point of view of a tall woman, I will have my next kitchen cupboards and laundry raised at least 10 cm to make my life more comfortable - bending forward for any length of time is seriously UN comfortable!

thanks how2girl, but I guess my question is more about polishing concrete that has been sealed/oiled than it is about concrete benchtops (hence those threads were a bit generic). A bit more research suggests to me that a sander is the tool to use. I'm thinking of attaching some used carpet to a sander. I'm still unsure of whether to use a polishing cream - I think it perhaps can't do any harm though, and may add to the shine. Then the question becomes whether it makes sense to add bees wax over the top. To me, it seems it would protect the shine. But I'm guessing all of this.
