door lining in a wide opening

[Jupiter01]

I am in the process of renovating my bathroom and approaching the task of door lining and door. I've gone to Wickes and checked on the door lining for my door.

The current opening that this needs to fit into is around 8cm more than the external dimensions of the door lining. There are no tiles in this opening. I thought this would be helpful as I have plenty of room to position and square the lining. The extra 4cm on each side didn't concern me as it will be covered by architrave.

When I watch the Youtube videos, the door linings are being fitted into much narrower openings. Have I overlooked something?

Thanks in advance

what size door do you have in mind?

is the wood brick, block or studwork?

 

[Jupiter01]

This is the door and the opening is wooden studs but note that I have tiled up to where the opening begins.

so if the 762mm door is 80mm too narrow for your opening, you can either batten the gap, or get a bigger door

the next one up is 838mm which is 76mm wider

I went for this door as its the size hat was in there previously and I don't have a very large bath.
Will I need to fit battens or can I just pad out (with woods) the fixing points of the lining?

 

[JohnD]

battens will be neater and you can fill the void with expanding foam (I use pink fire foam, but not much point as your door is made of air and cardboard)

your household won't like sound transmission through that door. I use fire doors to match the others, they are substantial and very good at muffling sounds.

When positioning the door into the corresponding door lining, will I have a 3mm gap all the way around? Is this what I am aiming for?

I’ve seen some suggestions of no gap on the hinge side.

If you dont leave a gap, when you paint it will bind

Is 3mm gap along the sides and top what I should aim for?
In fact is this, what I will be left with, if I buy the correct door lining and fit it plumb?

Ive always done 3mm on sides, 2mm at top as the door always drops with the slack in the hinge cut outs.

You must be using a wider architrave or not overlapping the lining by very much if its going to cover a 40 mm gap?

Thanks guys. The gap was less than 4 cm. good job I miscalculated this (again)!

I did notice that despite using the provided rebates, the door was too tight at the top. This was despite the frame being plumbed and straightened. I then had to widen the rebate by 3mm. It’s now good with a gap all the way around.

is this normal?
