    Hi all,

    I'm currently refurbishing a downstairs room into a shower utility room.

    The room is an extension onto the house, so the doorway is through the original external wall of the house (block inner leaf, outer leaf is those sort of stonework looking irregular bricks). This was done as a plasterboard lined arch way (no door)

    Naturally, now it will be a shower room, I want to put a door in instead. However the opening is only about 760 wide so to fit a standard 762 door obviously I need to widen the opening by a couple of inches. The lintel is plenty wide enough to accommodate this maintaining the minimum 150mm supported each end

    Question is - what's the best way to go about this indoors?

    Would you use a sabre saw with a brick cutting blade or chain drill holes and then chisel? Or something else?

    A 711 door.

    OK, that definitely would be one way to go!

    But, assuming I wanted to put in a standard 762 wide door...?

    It’ll make a fun-tonne of mess but quickest and easiest. Any other way will be time spent burning out blades.

    Seal yourself in, cut and move on.

    Word of caution - please triple check the lintel for correct spans. Folks don’t make extra work for themselves so lintels aren’t generally oversized for any reason other than they couldn’t find a smaller one at that time - not usually an issue for stock sized doorways.

    I’d be tempted to stick with a 711 door for the amount of effort...

    Thanks.

    Yeah, I'm starting to think the narrow door approach is the best option.

    711 wide doors seem to be quite uncommon and not available from the usual places I'd look, next common size down from 762 seems to 686.
