in tub and shower enclosures. What material to I use for the ceiling of the shower? Do I need to use cement board even if I am not going to tile?
Hi Uncle Bill, No, you will be fine with standard plasterboard 12.5mm as long as it's plastered and painted with a few coats of good quality paint. Hope this helps
I don't think it's code to use cement backer board behind your tile, but it's smart. You can use any drywall product you want for the ceiling, but I would recommend using greenboard or a like water-resistant drywall board. Even though it shouldn't see a direct water stream on it, it will see a lot of humidity from the shower.
