Plywood or MR board on stud

[Super_Paulie]

Any thoughts on this. 

 

I was going to just plywood over this before tiling so I've got strength for fixing wall mounted units. 

 

But I could also recess the plywood between each stud and then MR board over the top of that. 

 

Any benefits or just making work for myself?

Apart from someone missing the pan, what is the chance of that getting splashed?

 

Plywood should he fine IMHO

Basin will be on top of the wall hung vanity, sat on top of a worktop though.

Your tiling the wall and putting a vanity unit in front of it. I think you've got it covered 😀

Seriously, I think you'll be OK with plywood and tiles. Prime and/or seal the plywood before tiling.

You could always put a couple of coats of tanking before tiling to be sure, to be sure.

Just making work for myself ain't I. Seen online that people double up the board but I guess that's more for sound reduction from the flush and waste. Deffo need plywood in some capacity to hold the wall hung unit, which I currently don't have so can't position it up.
