12mm Ply + Cement board + Tiles on stud wall

[Possom]

Do you think, from floor to ceiling, 12mm thick plywood plus 12mm thick cement board (e.g. Hardiebacker type board or similar) plus metro tiles is a tolerable weight to be attached to timber stud?

Wall would be 1 metre wide by 2.3 metre high.


With this section of wall there would be a hand shower attached and also some shelving at the top of the wall. This is the purpose of the ply i.e. to give support.

Would it not be easier (and cheaper) to put noggins in the stud to fix the shelf and and shower to? Then there'd be no need for the ply.

There will be a number of 15mm diameter pipes, floor-to-ceiling, within this stud. If this makes it difficult/impossible to install horizontal noggins within the stud, then would floor-to-ceiling 12mm ply+12mm cement board + metro tiles be an acceptable weight for timber stud?

Apologies for confusing the issue - At this point I will bow out, and wait for someone who knows more about loading to answer your question.

No worries - thanks for posting.

Whether the studs can hold the weight depends on how well the studs are fixed. Hardie can hold 100kg's per square metre when fixed to studs, so assuming the studs are fixed correctly, no problem. It will take the weight easily.

If the area is subject moisture and humidity, ditch the ply! Its pointless and has no place in a bathroom situation. How far apart are the studs?

I've discovered that there's a local stockist of Schluter Kerdi-board, so I've decided I'm going to opt for this product instead.
