I have a vanity to fit in place of a basin. The only issue is there is a 80mm wide by 110mm heigh boxing in at the base of the wall it is set to be fit on. Where the shower waste runs in and tees up to the basin. Any one had this issue before and had to cut away the bottom back corner of the vanity. The purposed vanity is simlar to the one in the picture shown. Because of the boxing it would be unlikley I could get the pipes behind the banking piece at the back of the vanity. Thanks
