On our first outing with our new 26BHS, I thought we had a shower leak because my wife noticed water on the floor after taking a shower. After checking all the shower connections with no signs of a leak, I checked the toilette. The water line to the toilette was loose and dripping. Might check your toilette since you said there was water around it. Maybe it started at the toilette and not at the shower.
Note: we didn't notice any water on the floor before taking a shower on the second day. Almost like it didn't start to leak until taking a shower. Not sure why.
