Cooke & Lewis (aka B&Q) bathroom units question
 

SWMBO wants some slimline cooke and lewis in the loo we're redoing*.
If anyone's knows, can they tell me if they have *any* service gap
behind the (presumably) hardboard back (even a couple of mm would be
useful!), or if the back is completely flush?


TIA, Ben

* And the local store hasn't got any that she can actually check
dimensions on...
