Do i need to silicone seal this?

[vapd]

I had a plumber put up these tiles to replace ones coming off the wall. They are above the long side of a bath with a shower head (from taps) above and a sink to the right in the images.

When I noticed, after he left, that the side of the tiles in the images were not sealed I contacted him to ask if they needed silicone sealing and he said no. Only a few months later and I've got to re do the silicone along the top edge of the bath as it was clearly not done properly and has come away in a small patch. I've done it before, that isn't an issue. I kind of knew he hadn't done a good job but I just hoped I was being paranoid and now I think I probably need to do the edge in the included images as well?

Is that vertical? I'm never keen on vertical silicone

Yes it is vertical

Grout it. IMO

Eventually the whole bathroom needs to be ripped out and new everything. Can I not just silicone it as a quick fix? I only need to stop water from getting in for 2/3 years. I might have the money to get it all sorted by then....

Given the fact that the two edges are neither flat nor parallel, and there’s not a lot of room to run a profile tool down ( if siliconing), I’d agree with Warner’s and grout it.

I'll google that then!
