Honestly, when I bought the faucet…. I completely ignored the two ceramic tiles, that have been there since the dawn of man and apparently provide the building with such structural support that every contractor has not wanted to remove them. ¯\_(ツ)_¯ despite that…the faucet fits PERFECTLY, and honestly the drain is an awesome push feature which made me love it. Side note! This faucet runs LESS water than my last one which I LOVE and yes some may hate THAT, but I enjoy the fact that it uses less water because it flows a little softer than before. But I can still rinse my razors and and hands so it’s all good!
