So you expect someone to actually give you realistic advice on renovating a kitchen based on less than 15 words? Good luck. There's no way anyone can give you any helpful info without knowing a whole lot more like how much is your budget, whose doing the work, what shape is the current kitchen in, do you plan on replacing your floor and cabinets, will you be moving the plumbing, etc., etc. Answer those and maybe someone can give you some realistic help.

A kitchen designer would be able to help given the scope of work.
