Regrouting a Shower With Shower Floor Issues

Shower Pan: A waterproof “pan” placed beneath the floor tiles or concrete base of a shower that prevents leaking.

Water is meant to drain "through" the tile/grout

(Thanks to Mike Skala for the 3-D picture above)

The water in your shower floor is meant to drain both while on top of your tile and as the water seeps through the tile and grout… through the floor.

The “shower pan” is what keeps it from leaking outside, through the floor or anywhere else.

When regrouting showers many times you’ll find a big issue because the shower was not built with a correct slop or the water does not drain correctly.

When the shower floor/pan is not built so that the water drains away after it has seeped through the tile – this causes the shower sub floor/shower pan area to stay constantly wet.

This does not mean the shower will leak but it does mean that floor is never properly drying out causing mildew and other maintenance issues.

The video below is me using a tool to remove grout and as I’m using the tool, water is literally SPRAYING up out at me. The shower floor/pan area is soaked with water!

This is the true source of the customers continual mildew issue.

If they do not correct the pan issue they will ALWAYS have a shower floor that requires more work and effort to maintain.

You need to make sure your customers know this as (at least in Florida) it is a fairly common problem for the quick-build home builders to do less than perfect jobs on shower floors.

There are no “tile police” out there. There are no “inspections” for shower floors (although there should be) and the home owner ends up mysteriously having to battle mildew for the rest of their days….
