Fitting shower screen to wall above tile sloping to bath edge leaves a gap

[Paluro]

Hello Tilers
I recently fitted a bathroom for a (paying) friend.
One of the problems I encountered was the soil pipe which runs behind, then turns to run along the tap end of the bath. I made up the gap with 76 x 51 mm (3''x 2'') CLS, I tiled it forming a slope to shed water, grouted and then realised that the bottom edge of the over-bath shower screen would not reach the bath edge due to the sloping tiles.
I'm thinking of fixing some sort of post to the wall with the bottom trimmed to the slope and then fixing the screen to that. If that's advisable, what material could be used?
I'd welcome any suggestions, thanks.

I like that idea for practicality reasons and I'm pretty sure I've done it in the past.
Fix some timber to the wall and clad in a tile backer board of your choice and then tile .

Thanks, sounds like a winner. I'd thought of painted wood or maybe box section aluminium, but tile clad wood seems like the obvious solution.
