The onyx bases look good an are a fraction of the cost of a tiled base. As to stain free grouts---Latacrete makes an epoxy called Spectra Lock---Good stuff although unforgiving of mistakes---There is a Urathane grout which has received good reviews but I haven't used it yet.---Mike----.
The blueberry, named for its velvety, deep-blue color, is one of the few fruits native to North America. Native Americans used the berries, leaves and roots for medicine and used the fruit as a fabric dye. Blueberries originally are found in the wild, and now they can grow in many regions of the United States.
Blueberries contain a plant compound called anthocyanin. This gives blueberries both their blue color and many of their health benefits. Blueberries can help heart health, bone strength, skin health, blood pressure, diabetes management, cancer prevention, and mental health. One cup of blueberries provides 24 percent of a person recommended daily allowance of vitamin C.
