Hi, We are about to modify our kitchen to move the sink away from the stove. There is a dishwasher space beneath the sink even though we have no dishwasher at the moment. I have 2 questions: 1. Is it ok to leave the dishwasher space where it is b'cos it is expensive to change this. If not, what can we do? 2. If we do not move the dishwasher space and have a dishwasher there anyway but do not use the dishwasher often, what is the significance here? Thank you, May
