Which shower trap !!

[Shift]

Installing a stone resin shower tray to 25mm wpb and wish to use one of these http://www.hansgrohe.co.uk/uk_en/65957_32313634315F32355F3632333631.htm
My concern is the size of the hole I will need to cut in the wpb to accommodate the trap as the trays area over the hole will be unsupported and may be a weak spot.

perfectly normal to have to cut the wpb

Removing a piece of ply the size of a trap is not usually a problem.

If you are concerned by the size of the hole, you could mark out and trim away, say, hallf the thickness of the ply to take the trap.

If you do, Make sure there really is enough room for the trap when the tray is bedded down. If the trap fouls anywhere, you won't get the waste to seal to the tray.

Thanks for reply seco.
I know but if you look at the design of the trap the hole I think will be quite large once its raised up on the bed of mortar. I suppose its unlikely anyone will be jumping up and down in this area so probabally nothing to worry about.

Thanks Tickly T I did think of what you have suggested but don't think there will be enough margin for error.
