Shower tray fitting - is it proper to cut out plasterboard

[BoudinC]

Hi, i have a 1400 wide bathroom and a 1400 x 900 tray. I have had to disassemble and replace plasterboard etc due to a leak, but the recess between 2 walls is now less than 1400!

Is it possible/proper to scrape back the plasterboard to widen the recess?

Any help appreciated!

You don’t plasterboard shower enclosure.You board (aqua panel etc)over the top of the tray and seal before adding tile or shower panel .

Yes, if required.

+1 .... You can cut the plasterboard to allow the tray fit underneath.

Ideally though, as suggested, plasterboard wouldn't be used and replaced with a cement backerboard, either that or the space is then tanked to make it waterproof prior to the tray going in.
