You can buy butcher block counters from home depot or ikea
And other big box DIY stores have them.
Wood countertops do not meet Foodservice Health Codes, in the event you want this as a primary kitchen or bathroom counter. It’s because the pores of the wood cannot be truly cleaned and grow dangerous germs.
I highly recommend sealing them with a marine-grade varnish or polyurethane- making sure it has low VOC’s.
