hate to be a smart a--. your answer. a leak.
actually it could be 1 of a few things.
it could be.
hubby left shower curtain open, water leaked from floor
water leaking from drain
water leaking from drain to shower connection
water leaking from hole in membrane shower wall.
on and on.
first, go buy a shower test plug from a plumbing supply. tell them you want to test a shower pan.

put the plug in, fill shower with water. look and see
if no water leaks GOOD!!
let plug out. look and see again
if no water. you just eliminated drain and shower pan
pull face plate off the showere handles, look for evidence of water leakage from around the handles to shower wall
if you have a shower door, look
if you find nothing.
time to remove sheet rock. and look behind and under.
go below shower, cut a hole in ceiling, run the showere and with flash light look
