Fitting a 25kg bathroom cabinet to plasterboard wall General problems, solutions, information and advice on fixing to walls of all kinds

[CazB87]

Hello, I'm really hoping someone can help me here as I have spent all afternoon looking online at wall fixings and feel like I'm going mad!

I have bought a new bathroom cabinet from IKEA, it weighs about 25kg and I am unsure about the best wall fixings. the bathroom wall is tiled and plasterboard. I don't know where the studs are (I've just ordered a stud locator so hopefully that will help).

if I am unable to locate a stud (where I want it) and end up using two wall plugs, how much does each plug need to be able to hold? I've found plugs that for example say they will take 15kg, so by using two of them does that mean together they would hold 30kg or is it not that straight forward?

I've been looking at the Fischer duo power ones and then have just found these https://www.diy.com/departments/diall-nylon-steel-wall-plug-l-70mm-dia-14mm-pack-of-20/1584934_BQ.prd but it does not tell me the weight in plasterboard.

I have never spent this time considering a fixing before but do not have much experience hanging things on plasterboard, certainly nothing this heavy, so I am doubting every time I think I've made a decision!

Thank you very much for your help

Hi

The very best and most secure fixing will be to fix to the existing studs behind the wall. Do you know if it is indeed a stud wall or could the plasterboard have been dot and dab fixed to a more secure brick or block wall behind? If so then Corefix fixings are teh way to go: https://www.diydoctor.org.uk/product-re ... fixing.htm

If you are indeed dealing with a stud wall then there are a variety of different fixings to consider. We do have a project covering most of these fixings: https://www.diydoctor.org.uk/projects/f ... rboard.htm

One other decent plasterboard fixing product to hit the market can be seen in our review video here: https://www.youtube.com/watch?v=K1FwAIN ... e=youtu.be

You will need a specialist dry wall/plasterboard fixing when fixing to plasterboard to guarantee the best fixing possible.

Hope this helps

thanks for your reply. I don't know for definite what type of wall it is, I only moved in last year. The best I can work out is that the bathroom used to be a separate bathroom and toilet and someone has turned it into one room. The wall I want to fix it to is therefore half solid wall and half plasterboard (where the previous renovation has taken place). and I have only been able to determine this by knocking on the wall along the whole length, up to half way it sounds solid, then the rest sounds hollow.

I should have my stud locator today so I will have a go with that and will look at the links you posted. thank you!

I'd recommend using a stud finder, as securing the cabinet to this on the non-solid part of the wall would be best - you can use your stud finder for this.

If you know the area that will be covered you could try drilling a couple of pilot holes and see what comes out on the drill bit:

wood = strud
plaster board (no wood) = missed the stud
brick dust = brick

...then pick you plugs/fasteners accordingly.
