We have granite counter tops and are replacing a cast iron sink with a stainless one. We bought a 33x22" sink (which is the size of the Cast iron) and because of the clips (which the cast iron doesn't use) it wont fit in the hole. We bought (online) a 31.5x20.5" sink which is the measurement of the hole but don't know if that will work either because the clips may not reach. We really need some help here.

A. What is the right size sink, and B. What do we do to get the right sink to fit? We are new at this so I don't know if I've done something wrong.

  • Did the original sink have a rim on top integral with the sink? Or was the rim a separate metal piece and the cast iron sink attached to that? The prior sink was porcelain on cast iron, right? – Jim Stewart Jul 16 '18 at 14:38
  • I'm sorry. While its the same size as the cast iron, to install you have to use clips, which the hole seems to have been cut just to accommodate a 33x22 cast iron which doesn't need the extra room for clips. – Dan Haspert Jul 16 '18 at 14:39
  • The original sink is one piece. – Dan Haspert Jul 16 '18 at 14:39

    An over mounted sink will not need clips. RTV silicone (maybe even plumber's putty?) and gravity will hold it in place. Our soapstone countertop is cut on the underside for clips and has clips holding the under-mounted sink, but I think the weight is mostly held by the sealant, which I think is RTV silicone. – Jim Stewart Jul 16 '18 at 14:47

    Proper silicone caulk (would not suggest plumbers putty as it doesn't act like a glue) all around the "lip" of the sink where it meets the granite. Once the silicon cures it'll bond to the granite and the sink and hold the sink in place. – The Evil Greebo Jul 16 '18 at 14:56

Cut the countertop. If the reason it doesn't fit is because the clip bracket interferes then you shouldn't need to cut much. The countertop appears to be granite or some other solid surface so you would have to hire someone to cut it for you.

    There are almost certainly better options to be had than an expensive and messy stone cut. – isherwood Jul 16 '18 at 18:12
  • "Get the right size sink" would be a better answer. – The Evil Greebo Jul 16 '18 at 18:22
  • I appreciate wanting to get the right size sink but I've look everywhere and I cant find one that fits that hole. at least a stainless steel. – Dan Haspert Jul 16 '18 at 18:43
  • Evidently that opening was cut for the specific cast iron sink originally installed. Read the instructions for the first SS sink and the SS one that is coming. If the specs don't match the opening, don't try to force it. – Jim Stewart Jul 16 '18 at 19:53
