    Instructions for my shower tray state that it should be bed a concrete base, I guess to cimpencomp for the irregularities on the underside of the tray. But this tray has is not solid around the raised edges. Look at the photo, you'll see what I mean. Should hollow be left unfilled when installing?

    Concrete are you sure , it’s usually a sand and cement base or some recommend flexible tile adhesive

    Yes, sorry. Sand and cement.
    Don't fill the void then.

    No dont fill the void, flexible tile adhesive is what i use to bed them in the dry powder stuff mixed with a paddle mixer does the job . cheers kop

    I find powdered tile adhesive, easier to bed the tray.

    I use whatever the instructions say. Wouldn’t want to void the warranty before it is even used.
