Typically no, But you will end up with a much better job overall if you do. Reasons why would be for smoothness and ease of doing the tile work. But even more important is this is the best time to check your plumbing, upgrade your faucets, improve your insulation.
If your thinking that doing this will save you some money and time, the answer here is perhaps. Most of the older tile walls were not that well done to begin with and you would be hard pressed to find a pro willing to simply use the old walls instead of a complete gut and rebuild.
It is really not that hard to replace the walls over all. But the results area much better and the job becomes much easier then working new over old.
Thank you for your help!
Have you tried to remove the tile yet?...I have done lots of these over the years and if the tile comes off easily it was a crap install over drywall and the moisture has caused the paper to fail...which then means it has to go....The only time tile can be set on drywall is for backsplashes or wainscot type installs
Showers should always be set on backer board...period. Greenboard NO, denseshield NO.
If the tile was set well then trying to remove it results in extensive damage to the wallboard. I have found the best way to remove tile in these situations is the remove the tile WITH the wallboard. It is much faster and easier. I just started a shower remodel this week and the tile was set on green board 18 years ago. I pulled the tile and board together there were coming off in 2 to 3 foot sections.
@KMS Woodworks , I always thought greenboard WAS backerboard! Thanks so much before I got into my bathroom and wrecked it! What does it look like? Will I be able to tell cause you sure can't get any help at my HD...
Good advise guys.
Never would have thought to take both off at one time Kevin. What a time saver!
Sharron, Greenboard is just drywall with a water resistant covering, green in color, instead of the standard paper.
But Becky he said NO greenboard....to use Backerboard...I ALWAYS thought greenboard was what you were supposed to use....it's what we used in my mom's bathroom although she has a "surround" over the top of it, Long story...but the original plan was for tile so the greenboard went up...and then my dad decided he'd rather have a life with a floozy than continue to have our family...and all of us kids had to finish building their house to get her out of the winabago they had been living in while the house was going up...it was hard, financially draining, especially after myself and my sister were laid off during the economic crash as well as one of my nieces...so the money got tighter and tighter and she ended up with a tub surround.
Greenboard has the same gypsum core as regular drywall...when that gets wet it turns to mush.
The "green" paper skin on green board is just a touch more water resistant.
I was only explaining what greenboard was Sharron. Not to use it behind tile. It's what you use in areas of your home where the painted walls might come into contact with water. Like in a bathroom around a tub area.
OH!!!! Ok y'all I'm getting it...the backer is made by Hardiboard people...Gottcha,,, Yeah that makes perfect sense...
Hardibacker is my favorite of all of the others.
Wonder board is like grey cement between fiberglass mesh
Durock is similar
Rino board is a lot like hardi
I like the hardi because it cuts well with my thin blade diamond grinder
Kevin my hubby will only use Hardibacker. Hates cement board.
Ok I Know I've seen durock at the HD but not sure about the others, probably if I'd actually been Shopping for those items instead of looking for something else...
HoDe carries the HardiBacker too Sharron. We just recently bought some there.
Thanks for the clarification, everyone!
