wet room edging

[rego]

mother in law has just moved into property with wet room/shower. The vinyl upstand on walls is coming away slightly in places (not in area where water would ingress)
what would be best product to re stick this to walls

Any strong waterproof adhesive really, evo-stick impact would normally have been the choice though more modern equivalents/epoxies would be used now.
