Water is definitely present under shower floor panel. Very hollow and needs some attention immediately. I need a qualified plumber or equivalent to inject some waterproof resin or epoxy or suitable equivalent into my shower floor so that it fills the cavity and firms up the shower base so that it doesn't sag when somebody steps on it. Also need to ensure shower drain is connected to drain pipe correctly so water doesn't leak out through the drain connection to under the shower floor. Note: I have already got the shower completely sealed (ie. tiles have been newly re-grouted, all gaps have been sealed etc.) so no water is leaking out of the shower cubicle through these areas - Due date: Flexible
