Ask it in our Remodeling Forum or Homeowner's Forum . Large multibasin models, which are popular right now, will overpower a small kitchen. For larger kitchens, you can consider the added convenience of double and triple bowls that allow you to stack the dishes in one bowl while you rinse off vegetables in the other.
Many designers specify one main sink and a smaller bar sink for large kitchens.
Don't go for a second sink unless there are two or more cooks in the house who prepare meals at the same time. Whatever size and bowl configuration you choose, you'll also need to select the type of mounting you want. This is both an esthetic and a practical decision as described above. You'll also need to specify the number of holes in the sink deck. This number will range from one to five, depending on the faucet and the number of accessories like spray hoses and soap dispensers you add.
