The almond/bone coloured sink is 21" x 18" and fits in a countertop hole 20 x 16. The left and right faucet holes are 4" on centre. I am including pictures of the Moen faucet and pop up($10) that is being sold separately plus the FREE 49.5" x 22.5"countertop for a 48" vanity should the buyer want them. The sink is in excellent condition as it was from the guest bathroom and got very little use.
