I just had a new bathroom built. Contractor was unfamiliar with the shower wall panels' material (Muraluxe panels). The resulting gap between the wall and angled ceiling is pretty wide (1cm at the widest spot).

Corners between shower walls are more reasonably spaced, but still wide (3-4 mm).

Is it reasonable to fill such gaps with silicone caulk and expect water to not get across? If not, is there any extra remediation steps we need to/can take now, short of redoing the whole work?

(The shown Canadian quarter is the same size as an American quarter)

Can silicone caulk fill a 1cm shower gap?

Yes.

Just make sure to use a high quality silicone that's mold resistant and won't yellow. Make sure it reaches from one surface to the other.

Should I silicone caulk this 1cm shower gap?

If you care about aesthetics then it is a hard no. It will always be an eyesore and will yellow at a different rate than the rest of the materials used.

What can I do?

Hopefully you have not paid in full. Withhold final payment unless they properly fix their mess.

Find a length of S-shaped plastic trim, affix it, and caulk the mating points. The corner joints will probably look bad.

Get some PVC Cove Trim, quarter-round, or whatever, and install it to cover the gap.
