We used this sink to update an existing bathroom cabinet. It looks gorgeous on the quartz counter we placed it on. It was easy to install. Since we placed it up against a tiled back wall, we did not feel the need to bolt it to the wall and just silicones it to the quartz. I purchased a pop up drain and it leaked. A Plumber repaired the problem by using plumbers putty and said that without it, it would always leak.
