    I just installed a Delta single-handle shower valve in an acrylic shower enclosure and I'm wondering how to seal up around the cover plate.

    No matter how I adjust the plate, there is a small gap in the seal on the plate around the valve handle area. There is a foam ring on the cover plate, but it seems far from adequate to actually seal around the valve. Water bouncing off a body will almost certainly find it's way past this. Is this an area best left to silicone caulk ?

    Also, should I run a bead of caulk around the outer rim of the cover plate ?

    The provided foam rings are generally adequate. You can caulk if you wish, but try to achieve the smallest possible visible bead, because caulk inevitably becomes a maintenance issue.

    I've never had any call back issues with those foam gasket backed cover plates...I don't use any caulk.
