r/HomeImprovement on Reddit: Best Shower Waterproofing System 2021
October 31, 2021 -

Hi everyone,

I have a pretty standard but outdated 3'x4' shower in my basement that I'm looking to gut down to studs and rebuild. I am a new homeowner and have no experience doing anything like this, but I'd like to think I can do good research and follow instructions well. Wanted to ask around if there's an opinion on the best way to waterproof a tiled shower.

After doing a few dozen hours of youtube/reddit research, there appears to be three general ways of ensuring a tile shower stays waterproof:

  1. Liquid membrane (eg redgard)

  2. Fabric membrane (eg kerdi membrane)

  3. Waterproof boards (eg kerdi board, wedi board)

I'm not in the US, but I estimate the liquid membrane solution will cost me roughly US$300, kerdi membrane will be $500, Kerdi board $750, and Wedi $1300.

I'm not that money sensitive, just want something high quality that is easy to do, so I'm leaning towards Wedi's shower kit system even though it's a bit pricey.

I wanted to check if there's any consensus these days what the best option is, or if there's anything else out there worth looking into.

Thanks!

Best Shower Waterproofing System 2021
There really is no consensus. You're going to find people that insist that kerdi ( either applied fabric membrane over a drywall substrate or the Kerdi boards) is the only way to go and you're going to find people that insist that a membrane such as red guard applied over cement board is the best way to go. I'm a contractor that does many bathroom remodels. And I've used all three of the systems. My personal preference is the red guard applied over cement board. That is how I have been doing showers for many years. I've never had an issue and that's what I'm comfortable with and what I know. And after doing several cost breakdowns between all of the systems I do find that method to be the least expensive which helps lower my cost and maximize my profits. However the other systems are just as effective and work well. My suggestion to you would be to use whatever you feel like will be the easiest for you to work with. More on reddit.com

Best Shower Waterproofing System for Shower Pan?
I like the Hydroban products. They have premade shower pans, drains, liquid applied and sheet membranes. I normally use the sheet membrane which is similar to kerdi. It is a little more ridgid than kerdi and all of my guys agree that it is easier to install. Local availability might influence you however. We install Hydroban sheet or Kerdi directly over sheetrock. It cuts out us needing sheetrock for part of the bathroom and cement board for the shower. I don't like liquid membranes as much. I think they preform fine, but you have to wait for it to dry to recoat. You should be checking the thickness you are applying at to ensure proper installation if using a liquid membrane.

Bathroom Waterproofing Method

Coming from a 38-year journeyman tilesetter here:

Cheapest and easiest? Regular drywall on the walls, with Schluter Kerdi membrane and a Schluter shower pan kit.

100% waterproof. Easily applied by a DIY'er and comes with a 10-year warranty.

A much cheaper price-point than Wedi (I'm a certified Wedi installer), much easier than installing Durock (concrete board) and way less of a mess than applying liquid membrane over everything.

Schluter system for shower waterproofing
Schluter kicks ass. I did my first diy shower renovation at least 15 years ago with schluter kerdi. Easy and straightforward as long as you follow the directions. The cool thing about schluter is that it basically encapsulates your entire shower in a waterproof membrane. So, short of a catastrophic failure, water just ain't getting through. Any new shower I ever do will be with a schluter product. More on reddit.com
