Hi, I had booked a contractor to do the grille for the whole house and they told me the package will include grille for all the ceiling manholes. My dilemma is, is it necessary to have grille at the ceiling manholes even though we already had alarm install to them? I had looked at their show house and didn’t like the look of grilles at the ceiling plus I’m worried it will be hindering when we wanna install walk-in-wardrobe below it.

Another problem is my bathroom has a window shaped like an upside down ‘L’ and it starts at waist level height. It’s near the shower area, about 1.3m distance facing the shower tap. The contractor told me they’ll install grille from the inside instead of outside, as the window is open outward type. Will the grille rust easily with this proximity from the shower tap? I did ask the contractor about my concerns but of course he’ll say no problem, no rust etc. Are there any other options?

BTW, we ordered for 6mm thickness normal grille, not powder coated nor galvanized.

Thanks Kelvyn. I agree it looks ugly too so decided to ask the guy not to install the ceiling grille. But I think I'll keep the irons since already paid for it. Iron price is hiking up.

I'll ask the contractor about the additional coating.
