The question: Why is my shower floor discolored?
Floor discoloration is an ongoing issue with marble, natural stone, or porcelain showers. While the quick answers are that showers are failing due to improper installation, that is not always the case from our experience, which leads to homeowners never getting the correct answer or proper solution.
You must know your showers are not constructed or made water-resistant, not to confuse with shower waterproof. In the industry, there is not yet a method for installers to build a water-resistant shower, yet there are a lot of ways focusing more on waterproofing, never resolving the water infiltration problem under the materials, which are often misdiagnosed as a shower failure due to improper waterproofing.
According to the plumbing code, all showers are waterproofed under the stone or porcelain, followed by the Tile Council of North America (TCNA) industry requirements and installation recommendations. However, showers are not water-resistant on all the joints or corners perimeters after the shower enclosure naturally settles.
