Green board in the news - worth the hype for bathrooms?

I’ve torn out a couple showers where green board was used behind a membrane - honestly, it didn’t hold up great. Even with the membrane, you could see spots where moisture crept in around fasteners and seams. I just don’t trust it for wet walls. Cement board’s heavier, but it’s worth the peace of mind.

I get where you’re coming from, but I’ve actually had decent luck with green board in bathrooms - just not in the shower itself. For regular bathroom walls, especially if you’re careful with sealing and caulking, it’s held up fine for me. Cement board is definitely my go-to for shower surrounds, though. That stuff’s a beast to cut, but you can’t beat the durability. Green board just feels a bit flimsy for direct water exposure, but for the rest of the room? I don’t mind it.

Green board’s kind of a mixed bag for me. I’ve used it outside the shower area, and as long as you’re diligent with your prep - good primer, solid caulking - it does the job. But yeah, for anything getting hit with water, cement board’s just safer. I once tried green board behind a vanity where a pipe leaked... let’s just say it didn’t hold up great. Lesson learned. For the rest of the bathroom, though, it’s usually fine if you’re not dealing with constant moisture.

Had a similar experience with green board near a laundry hookup - thought it’d be fine since it wasn’t technically a “wet” area. Fast forward a year, tiny leak I didn’t catch right away, and the bottom edge was mush.

Tried purple board behind a utility sink - held up way better than green, especially when I had a slow drip from the faucet. It’s pricier, but honestly, after dealing with soggy green board, I’d rather pay a bit more up front. Marketing or not, it’s tougher stuff.
