We had to cutout the back of this unit to fit it to the piping on the wall. The product is good but the designer didn’t think of how it would fit to different pipe settings. It took us 2 days to do the adjustments and buy pipes and adabtors to make adjustments and install the vanity. Beside installation issues, the product quality is good. The shipment took 2 weeks but the delivery was very smooth and wayfair sent updates about the shipment and delivery process, regularly.
