Shaker White Vanity cabinet (36W x 34.5H x 21D), drawers on the left

The 36-inch vanity gives you six more inches of counter and storage compared to the 30, with drawers on the left and a door compartment on the right. At 21 inches deep and 34-1/2 inches tall, it handles standard vanity tops and undermount sinks with room to spare. The wider cabinet means wider drawers and a more generous door compartment. If your bathroom can fit it, the 36 is the better buy for daily use. 1/2" solid plywood, 3/4" birch full overlay, soft-close throughout.
