Hey everyone! I'm renovating my master bathroom and thinking about replacing the drywall with a wood ceiling instead. The bathroom is around 50 sqft, has a vapor barrier, and insulation above. It does get humid since it has a shower. I'm considering some tongue and groove hardwood options like Red Balau Batu, Meranti, and Bangkirai. I live in Calgary, Canada, and I want to know: Is using hardwood in a bathroom a bad idea due to humidity? If it's possible, what special procedures should I follow? Also, are those wood types suitable, or are there cheaper, durable, moisture-resistant alternatives? Do I need to apply waterproofing for maintenance?

Honestly, why not go with PVC beadboard? It's a bit pricier upfront, but it has zero finishing needs and would handle moisture much better than wood.
I'm not a fan of wood in humid spaces like bathrooms. I’d stick with drywall, it’s just a safer bet in terms of avoiding future problems.
If I were you, I'd definitely look into marine finishes for the wood, like the ones used on old sailboats. Applying multiple coats on all sides, especially the ends, would keep it lasting a long time. With proper ventilation, it should be fine!
Totally agree! Marine varnish is super tough, and I've used it too without any issues over the years. Just make sure your bathroom has a decent ventilation fan.
Consider fans with humidity sensors—they might help prevent mold if someone forgets to turn it on.
I hadn't thought about that! It does sound way more moisture-resistant.
