Standard vanity cabinet depth is 21" deep. A 22" deep countertop will give you a 1" overhang in front. Double sinks typically requires a minimum of two 30" wide vanity cabinets. Bowls are centered in each vanity. You can use two 30" wide vanities and a stack of 12" drawers between and center bowls over the two vanities. If countertop will not be abutting a wall, calculate a 1/2" overhang on each end of the counter.
Kid's Bath. This is above budget but we could select some less expensive tile to use this. Looks great with simple white subway. A ceiling to floor linen shower curtain would be divine.
This end table converted into an open vanity is perfect for a small bath. The polished countertop, vessel sink, and sleek faucet bring fresh design to limited quarters, while playfully contradicting the traditional base. The shelf below adds space to keep extra towels on hand.
