We received the vanity set and were somewhat disappointed by the quality. It is advertised as 100% hardwood, not particleboard. The back & floor of the vanity may be hardwood paneling, but it is certainly not constructed of solid wood boards. Also, the door and drawer facings and shelving are not made of 100% hardwood but some type of manufactured vinyl-like composite material.
In addition, the vanity set is advertised as having the backsplash included. We removed the packing material today as the contractor is ready to install and were dismayed to find no backsplash.  
It is a nice looking set, however, for the price it is NOT the solid wood furniture that is advertised.

I need to add an update:  Regarding the missing backsplash, we found that our contractor had moved it and placed it in our garage. Customer service was quick to address the problem before we found the backsplash, however, so I am changing our rating to four stars. Thanks, Wayfair!
