I am not convinced that our marble countertop has been sealed.  Water absorbs into the surface rather than repelled. I will apply a sealant myself to ensure that this procedure has been done.  Furthermore I had to install the backsplash even though your description implicitly states that there is no assembly required. These issues,  combined with the fact that our unit was delivered to the wrong Wayfair delivery center resulting in an extended delay has made my wife and I question our decision to shop at Wayfair again.  While we appreciate the credits that you extended us for all of our inconvenience we would much rather have had our vanity on time.  We have been looking at your company for a kitchen island to upgrade our current island however we are reluctant to do so considering all of the questionable issues that we have experienced.
