Moved into a newly built home recently. I went to change out the walk-in shower faucet and discovered that the tile contractor had omitted the grout behind the shower knob trim piece. They left 2 spacers in place as well. The cement behind the grout-less tiles seems normal from the little I can see. But there's no grout for about 8 linear inches of tile.

Shower knob trim removed with tile, grout and valve showing

The trim plate was held on by two screws into the valve assembly. You can see they sealed around the trim piece with a very thin bit of caulk; there was also a sizable amount of grout piled up on the trim plate where it crossed the grout lines.

My question is, how bad is this? Can I reseat or replace the trim plate with a same-or-larger size, re-caulk the edge and be safe from leakage? Or is this a don't-use-the-shower-until-fixed situation?

We do have a warranty process with the builder, but due to other recent experience, I'm expecting it to take over a month unless I raise an unholy stink, so I'm wanting a lead on the urgency before I contact them.
