In the end you should have a good idea which one will work best for your bathroom remodel.

Learning how to waterproof a shower is probably the most important thing you can do in a bathroom renovation.

The top three ways we suggest are

-cement board with a liquid membrane
-Schluter KERDI-BOARD
-Wedi building panels

Let’s talk about cement board first.

Cement board is cheap, about $12 for a 3×5 foot panel. So you’ll pay about $60 for 5 panels. BUT you should also factor in liquid waterproofing membrane…this will cost you another $100-$200.

Always use Alkali resistant screws to mount cement board to stud framing. NEVER EVER use drywall screws, they’ll corrode over time.

Use a paddle bit and hole saw to cut holes in cement panels. Angle grinders also work great, as you saw in the video.

The second method to waterproof your shower is KERDI-BOARD.
It’s way lighter than cement board, about 4lbs for a 48inch by 60inch board. Schluter provides screws and washers to mount KERDI-BOARD to the stud wall. Follow their instructions to a T in order for the warranty to be upheld.

We personally like having all waterproofing panels to sit on the tub lip. This prevents the panels from bowing out and your tile looking like crap.

Fill the gap between KERDI-BOARD with Schluter KERDI-FIX and embed KERDI-BAND in it. We have another set of videos showing you how to install KERDI-BOARD here

Adhere KERDI-BOARD to stud walls using Schluter’s screws and washers. The one thing that Schluter is know for are their meticulous directions…they will never leave you high and dry.

Once installed, flash all the seams and screws with KERDI-BAND using unmodified thinset.

The third method of waterproofing a tub is to use Wedi building panels. Again, they’re super light at about 11lbs for a 3×5 foot panel.

Wedi also attaches to the studs using their proprietary screws and washers. Apply Wedi joint sealant between all board transitions. Wedi is the easiest of the three methods to install.

You’ll see why in the video

  • Aye man I got a basement door at the end of concert stairs going down to the door the leashes if it rains to much but above the stairs above this is mostly a patio how would one waterproof the stairs

  • After having a home with a walk in tile shower, I prefer a fiberglass shower from bottom to top. I know it’s not the most aesthetically pleasing compared to a nice tile and color coordinated but it’s much easier to clean and can last a very long time.

  • Whatever happened to 15# felt, latch and cement plaster? I guess that's not slapdash enough for these so called experts. Just a screw up some backer and put goo over it, now that's tile work. What a laugh this trade has become. Too bad there are still a few of who recall how quality installs are done, until the handyman took over.

  • Except Kerdi is way toooooooooo expensive. I guess you get what you pay for, but it is overpriced. I mean a 12"x12" niche is $100. That stupid expensive. Then having to thin-set behind and then later over top for the tiles. While it may not be overkill in terms of waterproofing but its between its step process and cost, its not worth it.

  • I am in the middle of a bathroom rebuild. I had to take out the tile/drywall due to water leak and in the process decided to go ahead and replace the tub. I noticed while removing everything in the area that the tile was attached to sheetrock and the sheetrock was attached to the drywall. Is that necessary to do? I feel like that is just doubling up on protecting the drywall from moisture. Please let me know how I should move forward, thanks.

  • Method 2 or 3: doing my first install... should be interesting
