Tile over deep chase

[APM1990]

Im changing a bath to a tray for a friend and the bath was chased into the wall on all 3 sides.

Can I just fill this gap with tile adhesive or is there something else I should fill it with first before tiling.

Needs to be a quick turnaround though as it's the only bathroom.

Cheers

Board it with plasterboard if deep enough
