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)
