Conventional Showers Waste Water

Only 1 percent of the Earth’s water is freshwater available for our use.
Yet, when we use water - we waste water.

In a regular shower, water hits our skin for a second and disappears down the drain again. The average 10 minute shower can mean a monumental loss of a 100 liters or 26 gallons of water down the drain, plus the energy that it takes to heat it.

Constantly asking “Why?”

Why can’t sheathing provide insulation in addition to strength?

Why can’t being eco-friendly also be friendly to your bottom line?

Why can’t you cut your installation time without cutting corners?

Why can’t the best products be stably and competitively priced?
