We've received a few bathroom quotes and I'm trying to work out where we might be able to shave a bit of the cost. The quotes give a single price for labour, despite the job involving several trades - the room needs plastering, there's a stairs bulkhead that's getting boxed so there's carpentry work too, plus electrics and tiling. Would it be reasonable to ask for the cost of these trades to be split out on the quote? Or is there a reason it's not done like this? Thanks.
