I recently bought a house and noticed that in the primary bathroom shower, the silicone only covers a small area at the bottom and then it stops. The edges coming from the top have grout. Should I fill all the gaps with silicone? It's one of those prefabricated shower inserts, and I'm unsure if sealing it is necessary or advisable.

As a plumber, I'd say the door should absolutely be sealed, but the seams and bottom of the panels should be left unsealed. If you seal the bottom and you don't have a leak already, it could actually cause issues later on.
I'd avoid caulking unless you want to risk water damage and mold in that shower. Leaving it open can help any water drain properly.
Check the manufacturer's installation instructions first! They should clarify whether those seams need silicone. Following the official guidelines is always the best course of action.
Absolutely! Generic advice on this can be misleading, so stick to the manual for accuracy.
From my experience, I would recommend sealing it, but make sure to use mold-proof silicone. You definitely don’t want moisture causing mold issues down the line.

Thanks for the insight! So it makes sense that the seam shouldn't be sealed. It kinda trails off more from the door.
