You can use a center sink counter top for this vanity. I used a glacier bay countertop Model # 2237SQ-SLV3. A sink with those dimensions would work just fine. However, be careful which sink you do choose. If the sink is too wide or deep, it may interfere with the drawers. You'll also need to ensure your plumbing from the wall won't interfere with the drawers in that set up as well.
