Thank goodness such progress has been made in the advancement of modern toilets, or we would still be stuck in the 1950s when toilets used a whopping 7 gallons plus with each flush, or the 1960s. The number dropped to 5.5 gallons by the end of the 1960s and 3.5 gallons well into the 1980s, but since more progress has been made the modern toilet is capable of flushing with just 1.6 gallons or less. Pressure assisted toilets represent a true example of innovation, since they remove waste much more efficiently, as do water efficient toilets, which combine using a minimal amount of water with a maximum amount of flushing power.
Other progress has been made in the bathroom as well, with walk in bath tubs becoming more and more popular as more people decide to age in place or find safer solutions. Corner bathtubs are growing in popularity too, since they are differently shaped and normally deeper than conventional tubs. Soaking tubs have an ergonomic design and are deeper as well, allowing for full immersion.
What does this all have to do with bathroom vanities and sinks? bathroom vanities and sinks almost always get the updated treatment just as the other elements of a bathroom get their updates. As more advancements have occurred in toilets and tubs, more advancements have occurred too in bathroom vanities and sinks. This includes new materials that have less of an impact on the environment, and new materials that add more value too.
