Jessidog, that is the second thread I have seen where you have recommended Fiberglas (based) tile backer. Please tell me the name of this product or post a link to their website. I know of no such product. I could be learning something here.I would use cement or fiberglass based backer board wherever you have tile.
1. I also have never seen "water-resistant drywall". Where do you buy that?I would use water-resistant drywall
Hi Bud,Jessidog, that is the second thread I have seen where you have recommended Fiberglas (based) tile backer. Please tell me the name of this product or post a link to their website. I know of no such product. I could be learning something here.
Another question for you:
1. I also have never seen "water-resistant drywall". Where do you buy that?
Or...
2. Is "water-resistant" and moisture-resistant the same thing to you?
That was in a different thread, not here.As I noted in my previous comment, I was wrong about a fiberglass board.
Yow I know...I was trying to be diplomatic which is unusual for me.I was wrong about a fiberglass board.
Correct, most of them are. not all of them but most of them.The board that I thought was fiberglass is actually a cement-based product.
That product is a fiber-cement board containing mineral fibers not Fiberglas. It is called Hardibacker and only the 1/4" version has the grid lines stamped into it.More recently, I bought a backer board that appears to be a cement product. It is easier to work with and has an imprinted grid to help align the tiles. I'm not sure of the product name, but it is a nice product to work with.
There is not really a water resistant board in the drywall class. Those are "moisture" resistant meaning a little moisture won't hurt them all that much. Let them sit in water directly and the story changes radically.As for water-resistant vs. moisture-resistant, I'm referring to the green board that has been around for decades and was routinely used as backing for tile in showers and tub areas.
No apology necessary but in the case of showers and tubs accuracy is everything.I apologize for any confusion due to imprecise use of the terminology.
Just to clarify, but what precisely do you mean by "around the tub/shower"?My question is, (same as other person) how much of the bathroom should I use the moisture resistant drywall? My thoughts are Ceiling, and around the shower/tub.
Thank you for your comments and clarification on the various products. I learned a lot.David most of us here with some experience try to provide the DIY'er with accurate information at all times. Even when they do get totally accurate information here some of them either don't understand or don't pay attention, or believe everything they read. Some of them read it here and the next thing you know they are giving someone else advice here and things mushroom out of control pretty quick.
I don't often recommend products by name unless I am sure the recommendation is proven-out by my own experince.
You have made some additional comments that I would like to revise for the benefit of those that are lurking here and taking everything said here straight to the bank.
That was in a different thread, not here.
Yow I know...I was trying to be diplomatic which is unusual for me.There is no Fiberglas board product per say. However standard cement boards do contain Fiberglas threads or a Fiberglas mat but they are all embedded just under the surface of the cement product.
Correct, most of them are. not all of them but most of them.
That product is a fiber-cement board containing mineral fibers not Fiberglas. It is called Hardibacker and only the 1/4" version has the grid lines stamped into it.
The grid is not really to help align the tiles as the quality control on the grid placement is very poor. The grid is more used to help with the fasteners, in fact the board is also dimpled where the fasteners should go under most circumstances but not all.

Moisture resistant drywall is not for showers and tub areas. That is what cement backerboards are for. This isn't to say moisture resistant drywall isn't used in showers and tub surrounds but it should not be. Ever. There is only one application where drywall is allowable in wet conditions and that is when it is clad with a vinyl covering made exclusively for the purpose. Noble CIS and Schluer KERDI Mat are two of those products. There are others.

What I meant by around the tub/shower area, is from the top of the shower/tub which would be around 76 inches for the one I was looking at. so From the top of that to the ceiling, and including the ceiling. That was the area i was questioning the use of greenboard (moisture resistant drywall).Just to clarify, but what precisely do you mean by "around the tub/shower"?
I assume Bud interpreted this as outside of the enclosure. If you mean inside of the shower however, then no. No drywall products of any kind in a wet area unless they are protected by Kerdi.
