The raised rim on this Pennington oval bathroom sink will minimize the amount of water that splashes over the edge, keeping your countertop pristine and residue-free. This self-rimming white basin simply uses the force of gravity for installation-its outer edge resting on the rim of a cutout in your vanity counter that requires only a sealant to finish the job. Select this KOHLER model to pair with a 4 in. centerset faucet of your choice and give your vanity a significant upgrade for minimal expense.
