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

Honestly, I’ve pulled out enough mushy green board from “remodeled” bathrooms to be a bit skeptical. It’s not the villain, but it’s not the hero either. Cement board’s heavier and a bit more work, but you only want to do it once, right? For me, green board’s fine for low-moisture spots, but showers? No way. Learned that lesson the hard way... twice.

“green board’s fine for low-moisture spots, but showers? No way.”

That tracks with my experience. Green board just doesn’t cut it where there’s sustained moisture. Cement board’s a pain to haul, sure, but it won’t turn into compost behind your tiles. If you want to go greener, there are some recycled-content cement boards out now - bit pricier, but worth checking out.

Honestly, I get the argument for cement board, but I still think green board gets a bad rap. I used it in a half-bath remodel last year - granted, not a shower, but there’s a lot of steam from the sink and it’s holding up just fine. Maybe it’s about how you prep things? I’ve seen folks use waterproofing membranes or even those paint-on barriers over green board in showers. It’s less heavy, easier to cut, and way less messy than cement board.

Yeah, cement board is the “safe” choice, but if you’re careful with sealing and don’t skip the waterproofing step, green board isn’t instant disaster. Not saying I’d use it in a steam shower or anything wild, but for a regular tub surround with good ventilation? I’d risk it, especially on a tight budget. Sometimes it feels like the industry pushes us toward pricier stuff just to be “safe,” but there’s more than one way to do things right.

I get where you’re coming from - green board is definitely easier to work with, and I’ve used it behind vanities and in powder rooms too. The prep really does make a difference. Out of curiosity, has anyone tried using a liquid membrane like RedGard over green board in a tub surround? I’ve seen mixed opinions on whether that combo holds up long-term, especially if there’s a lot of splash. Just wondering if the extra step actually bridges the gap between green and cement board, or if it’s just a bandaid.

I get the appeal of green board - cuts easy and it’s lighter, but I’ve seen too many tub surrounds go bad over the years when folks relied on it, even with RedGard. Maybe it holds up for a bit, but once water finds a way in, the paper face can start to bubble or mold. Cement board’s just more forgiving if something fails down the line. For me, I’d rather do it once and not worry about hidden damage later.
