Hollow behind shower tray/wall.

[703810995]

Hello.

When applying sealant around the shower tray, if there is a relatively big gap (possibly bigger than 5mm) between the tray and the side panel/wall and hollow on the other side, what kind of product would I need to use to 'fill' the hollow space behind before applying the sealant? Would simply cutting the nozzle to a large size work securely?

Thank you.

Not much will effectively solve such a poorly fitted shower short of a refit .
