bath surround

[Robbox]

I have to replace our bath surround, which was originally 6mm ply and tiled on top. I prefer to replace with the 6mm grooved MDF and paint it.
I have made up the timber frame to secure everything to and I had some 6mm MDF left over, so that's the backing board for the grooved MDF. But I did wonder if 6mm ply would make for a stiffer end result.
Before anyone asks why backing board then MDF, the old underlying framework is such that to make a flat continuous surface for the MDF I need to fill in part with 6mm board. In other words the original chippie bodged it....

So loong as you have some verticals on your frame, all should be fine there......I'd go for 5 verticals, including the ones on the ends, obviously.

AHH....therein lies the problem, the bath legs go up to the bath lip, so cannot make up a frame with a top section. Relying on the crap bits of wood glued in behind the lip by bath manufacturer, to fix uprights...I've managed a total of four. Screwed the MDF backing board to all the uprights and there is still a bit of give. Maybe once the top layer goes on it might feel a bit better....that's kinda why I thought about ply, since it is a much stiffer material.

I wouldn't use Weetabix for a bath surround.

Less fiddily than cornflakes.

If it's green MDF and well painted, it will be fine.

If you want to stiffen up the panel, stick the first panel to the one behind with plenty of no nails or similar.

Even green MDF is a big risk and a risk too far. MDF is plain and simple the wrong choice and there is no advantage to use it anyway.

T&G matchboarding looks good round a bath.

Big risk and a risk too far? He isn't using Semtex. I had a Green MDF bath panel in my previous house for years with no problems at all and fitted a shop bought one recently for a customer that had doors in it for storage. It was painted MDF.

Aye MDF is a bodge and anyone who says it will be OK is a bodger, any shop bought one is a crap product.
