There are a huge amount of pros for using Quartz in your project.  As well as being available in almost any colour you can think of, it has twice the strength and durability of Granite.  It needs very little maintenance other than a clean in warm soapy water to keep it in pristine condition, and there is no need to concern yourself with staining from spills.  Quartz is scratch resistant, stain resistant, mould & mildew resistant, and requires the least maintenace as there is no need to repolish or reseal is once it has been fitted.
