These are a super deal. Not online, B&Q description is NAT26CUBE 4 Panel shaker cube oak veneer SKU 3727010 size 1981 x 762.
Just purchased 12 from the Gloucester store, they have about 60 in stock.
These are real oak veneer, yes base is chip but then so are any doors less than £150 each.
Closest I have found to these in quality/style have been around £90 each.
762 is 30 inches (2ft 6). Doors are still sold in imperial sizes. 30 inch is a common size for houses built since the 60s but check as they went narrow in the 90s and wider in recent years due to disability regs.
I think they only have this one size, I'm building a house at the moment and these will be perfect. Chippie working with me is astonished at the price and has taken a long lunch to go and buy 20 or so.
Almost all cheap doors look cheap, these are different, they look to be worth at least 5 times the price paid.
