Hey lads, I'm not a fitter, just a soon to be customer, i'm sat here scratching my head wondering how on earth a laminate worktop is properly fitted above this base unit, so that i can order the correct amount of worktop. I'm visualising a small triangular joint at the back? Not a clue. The corner unit has a neighbouring 300mm and a 600mm unit. Also I was going to order ABS worktops, is this ok? Thanks in advance.
