r/HomeImprovement on Reddit: How to water proof walls around shower/tub
August 11, 2022 -
What’s the best way to water proof this shower/bath? Going to tile it with some kind of tile. Heard of using cement board with vapor layer . Do I replace the remaining dry wall at the top?

Cement backer board gives rigidity so the tiles and grout won't crack. I can't see a picture, you can upload to imgur, but you don't always have to cement board to the top, unless you are doing a steam shower which would need ceiling vapor barrier. As long as you have good ventilation and a door with a gap at the top, then you shouldn't need to go all the way up. Steps are: Level walls, use 4ft level across and in a X pattern to ensure they are plumb. Taking time here will save you many headaches down the line. cement board on walls (Kerdi boards are an expensive light weight option) fiber tape and mortar joints paint on red guard or similar waterproofing substance second coat of red guard. then thinset troweled out with tile. finally grout. Might have missed a few steps, but that's the general idea. Literally halfway through tiling my shower last weekend, about to finish it up.

Remember that the ceramic tile is not what will waterproof your shower. It is what is behind the tiles that is important. No matter what you do, your shower needs to be water proof before the tiling happens. There may be case where just tiling will waterproof that I am not aware of but that's the advice I can tell you.

April 5, 2023 - For the mixing valve and showerhead pipe holes, I added a layer of mud around the hole-shaped openings. After smoothing that coat out, I applied the seal for the mixing valve. Make sure the thick side is facing the mixing valve inside the wall! After installing these seals, I added a coat of mud as needed to the outside layer. Now that I had waterproofed every part of the shower except the curb, I next turned to the bench.

August 11, 2022Bathroom walls are out, insurer claims no need to waterproof the floor?
The Australian Standard 3740-2010 says that the minimum requirement is that shower area floor needs waterproofing with a continuous membrane. This is just the shower area, not the entire room. However, the entire floor needs waterproofing if it’s on a 2nd floor. If the bathroom sits directly on the slab then the entire room doesn’t as per the AS, just the shower recess area. Best practice would be to do it all, but it’s not a requirement under AS 3740-2010 unless it’s a second storey bathroom. More on reddit.com

September 11, 2022 - There is more than one way to build a waterproof shower but they are all unforgiving in that the tiniest of mistakes means a water leak that becomes mold and rot given some time. If all they did was nail cement board to the studs and slap on the tile my guess, is it will all get redone in less than 5 years. From the photos it looks like the floor may be curb less making it very difficult/ impossible to test the floor pan.

August 11, 2022 - I assumed he would say we had it, but instead he said there is no membrane beneath the shower floor because that would have required two pours (the house's whole footprint was done in one), but there is waterproofing on the walls (I don't know what it's called; it's purple; pic attached) and the shower-adjacent walls were framed with wolmanized wood, so it should be fine.

August 5, 2021 - Also, you can use the standard seam strips in nonstandard ways: around the edges of niches and curbs, and even around the entire floor—taking advantage of their strength and crack-isolation properties. Foamboard systems can be used for walls, the pan, or both to create a shower substrate. Most systems also offer preformed niche boxes that integrate nicely as well. Between the parts and over the seams goes a liquid-applied elastomeric sealant, creating a fully waterproof substrate with an excellent factory warranty.
