In my home I have a single piece shower / tub fiberglass unit... something like...
The spout looks like...
Also, for some reason there is a round sheet of plastic that goes between the spout and the shower wall. Which creates yet another complication for caulking. The plastic looks like it is to keep water out of the hole in the fiberglass that the copper spout pipe goes through.
[diverter tub spout][round plastic sheet][fiberglass shower wall]Does anyone have any suggestion for how I can properly caulk this spout?
My current plan is to:
1) tape the plastic sheet to the shower wall using blue tape.2) caulk the gap with clear silicone (the gap has no backing because the faucet is hollow)
3) let the caulk dry (maybe apply a second coat)4) caulk around where the plastic sheet meets the shower wall
I have now begun to think that maybe I should glue the plastic sheet to the shower wall, and then do (1), (2), (3), and (4).
Unfortunately this is a new home I purchased from a tract builder and so I do not have any installation instructions for the tub/shower unit.
