5 Questions from the Community
-
Does this come in 8 inch openings for the faucets?
-
my sink dimentions are 20" x 17.5" will this replacement will fit
A. Possibly as this is a drop in model & the dimensions are close. The best way to tell is to look under your sink & measure how large the cutout hole your current sink is in to be sure that this one will have adequate space to rest the lip of it on. The basin dimensions are 16" x 11" so the cutout hole would also have to be large enough to accommodate that size basin. Please let me know what questions you may have; I am happy to help!
-
What is the difference between K2905 and K2906? I want to replace an existing K2904
-
does the sink come with brass or chrome fittings on the bottom drain and the top overflow drain?
-
Can I get this sink with a predrilled hold for a soap dispenser?
