I've recently moved into a converted flat where all the internal doors are 44mm deep - I assume because at some point there was a need for fire doors.
I'm really keen to replace them all with 'normal' looking doors, but am struggling to find anywhere that stocks doors of this depth that aren't fire doors (and therefore charge fire door prices). Does anyone know if such doors are common or where I can find some? In particular ones that have frosted glass for bathrooms?
If not, is my only option to fit regular 35mm doors (of which there seems to be a huge range) and somehow 'fill' the door frames so that they fit well? If so, how easy is converting a door frame to fit a thinner door?
Thanks for any advice, all a bit new to me...!
