5 innovative toilet-sink combinations

Eco-friendliness has been one of the most sought after approaches in recent times owing to the realization on the environmental impact of human practices. If we give due consideration, we can see that eco-friendly approach can be adopted at home. For example, wastage of resources or the impact of environmental friendly air conditioners cannot be underestimated.

The bathroom is often the room in the house where the most water is wasted. According to statistics, the average household uses 138 gallons per day, with 50% of that being used for hot showers, baths, and toilets. This has led to the development of more efficient toilet technology, such as the SaniCOMPACT toilet, which saves both space and water.

Thus, for those trying to adopt eco-friendly approach at home, various approaches have been designed.


The best way to save water resource is to conserve it. We all know how much water gets wasted on flushing in toilets, during showers and in kitchen sinks. New ideas have come up which combine the utility of these entities. Let us have a look at some of the ideas.

  • Water conserving sink, shower and toilet combo

Similarly, there is an elegant glass container which stores the water for later purposes. This also lets you know how much water you have stored. This stored water is then used in sinks and for toilet flushing.
