Narrow architrave for door frame

danrv

Hi
I need some 30mm wooden trim for a bathroom door frame. The walls have been plastered and there’s 30mm of frame showing and the original trim was 45mm.
It’s only one upright as the rest is quadrant.
I can fit a 45mm piece but that means chipping off some of the plaster.
Can’t seem to find much in the way of narrow trim.
Any help appreciated.

One of several ways of doing this, depending on what tools you have available.. Cut a thin strip of wood the thickness of your plaster skim (say 25x3mm), attach to frame and then fix your architrave.

Cut a 3mm rebate on the back of the architrave so that it sits firmly on the frame carcass yet just clears the plaster.

Run the architrave through a band/circular saw to reduce it to 35mm width.

Next time, remove any/all architraves and get the plasterer to plaster right up to, and flush with the frame. Plastering up to an architrave/trim always leaves a messy edge that needs further work to blend in.

That’s great, thanks.
Yes. Didn’t realize it was a standard size and thought I could just get something to fit.
I have a router and circular saw but not bench mounted ones.
I think I’d prefer it flush on the frame like the original so I’d need to either:

Cut a 20mm x 8mm rebate out  (original trim is 45mm x 13mm)
Trim it down to fit
Cut away the plaster

Are you referring to the architrave and is the piece in the top photo the piece you have removed and matches the exiting architrave on the opposite side and door top? Or is it the type of door frame that goes all of the way to the ceiling so you only have one strip on either side?

Looked at photo again - is that your bathroom door? If so and it's the right hand architrave then I'd measure where the full size architrave will go to on the plaster then score the plaster with a stanley knife and chip off the extra thickness of plaster. Fit the architrave and fill any damage to the plaster with either Polyfilla Easy Sand or Gyproc Easi-fill (not used the latter but someone recommended it on here recently)

Yes, bathroom door.
That’s the original and only piece. It’s the same on the other side of the wall.
There’s only architrave on the RH side with quadrant at the top and other side.

I reckon I’ll cut away the plaster as suggested.
The old plaster was taken up to the edge of the 
architrave.

Ah yes our upstairs doorways are like that - I hate them but the glass has been replaced by some ply.
You might as well chip the plaster as it's not a straight edge to work to - I did this on a couple of my doors recently.

Are you having tiles down to the floor? If not your skirting board will protrude past the architrave. You may have to get thinner skirting or chamfer it.

That's a good point. Depending on what skirting you have or if you need to buy some you could get 18mm thick architrave and 14.5mm thick skirting

Thanks. Hadn’t thought of that.
Probably won’t have tiles down to the floor as before. The door shuts flush with the frame 
so chipping away plaster would suit there.
May change the door eventually 

Skirting then would need to about 6mm but could raise the architrave to level with it.

Yes. I’ve seen 18mm x 69mm available.
Haven’t got around to finishing this yet as I’m been fitting the bath in.
Pics show the original architrave and a loose off cut of 16mm skirting.
First one is with the architrave brought up to the skirting level but this leaves a gap.

Speaking as an OCD carpenter I would source material to pack out door lining so that the architrave match the skirting board.
