A 1981mm door I can take ~20mm off..?

[PeteWilliams]

Hi,

My house has a load of 6 panel doors upstairs that aren't my cup of tea and want to replace them with simple, flush ones. The problem is that all the existing doors are around ~1965mm high, so I'm looking for a flush, hollow 1981 x 762 x 35mm door that I can take 20mm off in height - but these don't seem to exist! With most I've seen online, it either doesn't say or it says you can only trim 10mm off.

Anyone know where I can find something suitable? Have spent a couple hours looking and found nothing!

Cheers

Pete

Take 10mm from top nd bottom ?

 

[PeteWilliams]

That's the plan but I've not found any that will let me. They all say max 5mm from top, 5mm from bottom.

10mm will be fine

Ok, silly question time. When looking at the measurements listed for a door, are they the measurements of the door, or the measurements of the opening…?
Google is returning conflicting results…

I ask because I measured the height of my openings, and they're 1981mm which is a standard height for doors - though they are about 770mm wide, which isn't a standard width…

It's the size of the doors. You're talking in mm here, small increments, depending on the competency of the person that constructed the door frames, movement, paint layers etc you're going to get differences. Have you measured the width at both the top at the bottom? These aren't likely to be the same either.

762mm is the standard width for a door, so it probably means you'll have to take very little off the width of the door for it to fit.

Not sure what your woodworking skills (or tools are like, but if you took 20mm off of the bottom of the door, then there'd be about 5mm left in the door. If you chisel this out, and then plane the hardboard off of the wood you cut off. The hollow door just have cardboard inside them to provide support, so just rake that out, and glue the piece of wood back in to the bottom of the door, and then clamp it in place.
