No the over flow is made right in the sink it self and works just dine
The diameter of this sink is19.125
No it doesn't I prefer a soap tray it self
19 inches in diameter. The cutout should be 17.75 to 18 inches.
All popup stoppers are interchangeable to fit all sinks the same way, and you can get them in chrome or gold color.
In the *five years* since the original question was asked, *no one* has given a direct answer. Helpful KOHLER Customer Service tells us to use the template provided with the unit (when it's already been purchased). Helpful Hank tells us to 1. go find his previous post, which tells us to 2. locate and download the .dxf template from the KOHLER website, and then 3. convert the .dxf file to something readable...but then never gives us the cutout dimensions. The HomeDepot page tells us that this sink with an "Inner bowl front to back length" of 12 inches and an "Inner bowl side to side width" of 14 inches is supposed to drop into a countertop cutout with a "Front to Back Width" of 4 inches and a "Left to Right Length" of 12 inches...does anyone see any problems with these dimensions?
Cut out is the inside circumfrance or diameter of the sink. You want a snug fit and not a loose fit or it will move around when using a drop-in sink!
The Kohler sink is 19". If you have a 18" round hole it will set in fine. If it is a tight fit you may have to make the hole a little bigger. You should be fine.
All I know is all Home Depot sell this product, they may not carry it in stock, but I ordered two of them online, and it you go to the store they will order it for you.
Any standard pup up kit at Home Depot will fit and work
