In my tub/shower, between the tub and the surround there is what to me looks like trim. In every surround I have seen or can find online they just chaulk between the tub and surround. Does anyone know what this is or what purpose it serves. It is impossible to keep clean and is a headache. Could I remove it and just chaulk the tub like other tub/shower combos I have seen?

Since there appears to be a slight curve above your "trim", I think your surround was either made that way (to need trim) or it is installed high for some unknown reason. One picture doesnt explain it. If we could see the ends where it meets the walls it would help.

Also, its CAULK. There is no "ch" in caulk. Chalk is for chalk boards.

Is that trim supposed to be vertical? The forum photo attachment function is pretty crap.

Yes, you can remove this vinyl strap, clean well and do a re-caulk job.
I like to use DAP, not silicone.
