Tiling Bath Panel & Floor

[shazz316]

Not sure if this is the right section for my question but here goes.
In my bathroom, I am tiling onto floorboards + WBP plywood layer and an aquapanel bath panel. (New frame for bath panel also has to be fitted).
Its only a small bathroom with one bath panel required along the longer side of the bath.

Questions:
(1) What would you fit first prior to tiling - ply floor or bath panel?
(2) If ply floor is fitted first, would you fit ply floor so that the bath frame and panel rests on top of the ply floor or would you fit ply level with edge of bath and just rest/secure the bath frame and panel to the floor boards.
(3) If bath frame and panel is fitted on top of ply floor would you also fit the ply floor so that the front 2 legs of the bath also sits on top of the new ply floor. This is the way the old thin plywood floor which I removed, was fitted.

I’d fit the ply overboard completely under the bath; I’d then tile the floor, again, tiling beyond the bath line & under the bath at least 300mm & then fit & tile the bath panel. This will provide a level base for the bath & the ply overboard a degree of protection from any water that may find its way inside the bath panel; if the ply gets wet & expands, under the tiles, they will fail.

In the design/construction of your bath panel, you should considered how your going to access waste & plumbing connections in case of future maintenance issues.

Hope you used minimum 12mm WBP, screwed into the joits & you sealed the underside/edges? Make sure you use a decent cement powder, flexible adhesive & grout not cheapo DIY stuff.
