i moved my fridge to another location and the washing machine to the end. I plan on fitting a 500mm base unit in the gap however I am left with a worktop that stops where the fridge was. Would I need to replace the entire length of worktop or can I buy one and use an off cut to attach to the current one? (I am getting a joiner to do the job). The reason I am asking is because I don't really want to risk taking the entire length of I case I damage the tiles. thanks in advance.
