What's under your shower pan?
Have you ever noticed the mold which continues to
grow along your shower floor and wall, sometimes
growing up along the corners?
No matter how much you clean the mold (use
bleach diluted or commercially available mold
cleaners) it seems to come back.
This can be evidence of a leaky shower base or
faulty shower pan liner installation.
Another scenario is the obvious, mold growing
outside of the shower stall, spongy flooring next to
the shower and plaster bubbling and wet, water
damage to adjoining walls or ceiling.
Let’s say there are no obvious leaks yet mold
persists. Unfortunately this is evidence of an
underlying problem that should be addressed.
Mold is unhealthy and left unchecked can
cause not only health problems but financial
woes to your investment in your home.
Mold in the shower base is not normal. In most
cases improperly constructed showers and
shower pans are the culprit for this unhealthy
So if your planning on a bathroom remodel that
will require installing a new tiled shower make
sure that you hire an expert remodeling
contractor in this field.
Things to look for:
1. How your shower seats or benches are built if your bathroom remodeling plans include these in your shower. Benches or seats should be built
inside of the tile pan using cement blocks, and covered with durrock, wonderboard or floated out with cement. This requires real skill from a
professional tile contractor who is interested in working for the lasting benefit of your home improvement project. For the do-it-yourself homeowner
pre-made benches and seats are available.
Unless you’re an expert I don’t recommend wood framing your seats since it’s been our experience from the tile repairs that we have performed that
done incorrectly wood framed seats resulted in rapid mold growth.
2. When installing a shower base liner make sure your floor contractor includes a pre-slope to drain before the pan liner is installed, if this step is
skipped mold issues will not only appear but damage to the shower pan floor will be so severe that the entire shower base will need to be replaced.
Weep holes in the clamping shower drain ring necessary for proper drainage will need to be kept clear.
3. Proper drainage for a shower stall floor is ¼ inch per foot to drain. In other words the slope to the drain should look and feel unnoticeable. A bad
mud job can instantly be felt when standing in the shower and if standing water is left after showering this may need attention to correct.
4. The correct tile backer board will need to be installed. For years green board was used in every wet area application by homebuilders and
contractors alike. Today knowledge of how the popular tile backer boards are installed is essential for a successful tile installation. Some
manufacturers recommend leaving a gap between the bottom of the wall board and the horizontal surface thereby reducing “the wick” effect of
improper installation. Also some materials are not recommended in shower stalls and steam showers all together. Make sure that your tile installer or
bathroom designer is well aware of the different applications and limitations of the differing bathroom tile products available today.
What’s under your shower pan?
Hopefully a dry floor, a pre-slope to the drain and unclogged weep holes.
