What I used is the the most expensive type plywood they sell I don't know the name but it was about 30.00 for a 4x8 sheet and it has a finished side almost furniture quality that is the best that I could find, it's heavy but straight.
I don't have a wood shop with alot of tools so what I did was go to lowes and bought the stock 48 inch counter top with a nice back splash build in and they also have the matching 4x8 sheets.
They sell the same counter tops longer but you would have to cut it and have some waste if you went with a straight counter across the front.
I left enough space behind so I could use that area like a small room and that is where I have my bathroom and alot of storage, but I think you could use the straight counter and push it all the way until the V starts and build cabinets space behind it>? you can never have enough storage space ?
This is the way I got the best desired finish without alot of building, and it was easy to cut a hole in the top?
