Hi Lisa, here's how one blogger made her kitchen countertops out of wood: https://www.simplymaggie.com/diy-wide-plank-butcher-block-counter-tops
When i did my kitchen remodel several years ago, I built my own kitchen countertops. I used plywood for the base, 1x2s for the aprons and glued sheets of Formica laminate on them using contact cement. They were super-easy and inexpensive!
Countertops can also be renewed with countertop coatings ( Daich and Giani are two brands I've used, or the tops covered with marbled vinyl by DC-Fix.
I hope this helps and if you have further questions, please let us know!
kitchen countertops have to not absorb any food particles at the molecular level.
they need to tolerate serious scrubbing and cleaning chemicals
they need to be somewhat heat resistant
plastic laminate needs to be cut with a router in my experience, but it is cheap for what you get.
