wetroom form has slight dip

[nick9one1]

I have installed a wetroom form (the style below). I have removed the floorboards and lowered the floor so that the form is fully supported.
I haven't adhered the form down permanently it yet, but during testing I have noticed that it has a slight dip just before the drain where the water pools slightly.
If I was using large format times I wouldn't be concerned as it would be quite easy to ensure they had the right drop and they would span the dip.
But im using mosaic, I'm concerned they will follow the dip and be difficult to get perfectly flat and also have the correct drop.

Any suggestions?

Is that picture from your project? If so, you will have to reinforce underneath the wet room tray. Recess the floor.

no it isn't.
