Part 5: Conclusion

The final post of this series will review the three different methods for waterproofing a residential bathroom shower that have been previously discussed and the whys, or why nots, for each method.

Traditional showers

The good:

lowest cost

tried and true

Not-so-good:

water is allowed to soak into substrate which may lead to mold growth and minerals coming to the surface (efflorescence) through the grout

Liquid surface waterproofing

Surface waterproofing is applied over the surface and the tile adheres to it. (Image courtesy of Laticrete International)

The good:

blocks water at the surface, rather than letting it absorb

easy to install

Not-so-good:

lack of vapor protection

more prone to user error by not getting spots thick enough

Waterproof sheet membranes (and foam board)

The good:

blocks water at the surface, rather than letting it absorb

excellent vapor protection

Not-so-good:

expensive

sheet overlaps can cause flatness issues

It’s important to remember that all three of these methods are specified by the Tile Council of North America. There’s no right or wrong, it’s up to you to choose the one that works the best for you.

If I had my choice, I would use a sheet membrane on every project. I think it’s the best way of waterproofing a shower. Unfortunately, not every budget allows for it.
