Wall mounted sink on plasterboard wall?

[Possom]

Can a small wall-mounted bathroom sink, ~35cm to 42cm wide and so not a pedestal nor a half-pedestal, be mounted on a plasterboard wall?

Or should they only be mounted on brick/block walls?

This sort of thing:

Thank you.

It can if there's some decent timber behind the plasterboard, otherwise it'll most likely fall off

Even if there are not existing timber studding behind the proposed position there is still a possible solution.

That is to use a sheet of adequately thick MDF behind the basin but wide enough to span two ( or more ) studs.

But it does need to be adequately waterproofed as its so strong when dry but very week if allowed to get wet.

But an alternative is marine ply but that's so expensive!

The next question will be how to find the position of the studding!

How do you find the position of the studding? *only joking!*

I was really just wondering to know whether there's any point in my purchasing a wall-mounted sink, or if it would have to be a floor-standing sink, which I'd rather not get since it's a very small bathroom.

Better to estimate the stud position before you buy anything.

I usually identify by tapping.

Sometimes you can identify nail positions.

MDF jesus agile I do wonder about you sometimes.

Ok, so you mean do this, and once the separation is known this can be used to ensure the separation between the sink brackets matches?

Therefore, meaning neither the plasterboard does not have to be cut nor a new supporting timber installed.

No point in cutting anything until you know for sure if anything actually needs to be cut.

MDF is actually very strong indeed. Stronger than most cheaper wood.

Okay, well the wooden paneling which is over the plasterboard will have to be removed first though as the thin pine panels will make it difficult to locate anything via the tapping method.

Mdf is about £18 a sheet and you can get 8 x 4 ply for £25, I know what I would rather use, as for mdf being strong ....

WPB ply is now more like £45 a sheet.

Sorry T, you won't catch me using mdf in a bathroom. . Stuff works better than a sponge.

structural ply 18mm £30 a sheet.

Don't use MDF for bathroom. If it get wet, it will swell up. Don't know why they still using MDF in housing stock bathroom replacement in my area.

Cut out plasterboard between two studs where you want put basin in, fit batten on studs and fit plywood onto batten flush with front of studs and then refit plasterboard and make good with easi-fill.

Then fit basin as per instruction.

Ps, you can get 1200 x 600mm plywood from Sheds.

Telly Tony and MDF in bathroom!!! MDF works like sponge and will wick water horribly

This is a normal situation where a neat square can be cut out using the legendary plasterboard saw and WBP Ply is installed and fixed to joists with some noggins as necessary.put the plasterboard back and seal joints as necessary

WBP Ply is not the same as marine ply Telly Tony .It's around 25 _30 quid a sheet in most merchants

The initials WBP are in regards to the glue used in manufacturing process.
