I'm new to this! Does anyone have any tips for a narrow bathroom that only has space for a 18" deep vanity? It's 30" wide. We’re especially having trouble finding a small enough sink. It's a full bath with a clawfoot tub, but we want a more contemporary look. As you enter the bathroom, the sink and radiator are on the left and the tub and toilet are on the right. There’s a window straight ahead.
