outside is 3.25inch , and the gap is 1 inch

The inside dimension measurements are probably swapped. If the basins are each 16.5" left-to-right and the divider is 1" then the total cutout size is approximately 34" L-->R, the flanges are 1" on three sides, and the *faucet deck* is 3.25".

Starstar/Houzz: it'll be helpful to mark the 16.5" measurement as "length" so it's consistent with the outside measurements' labels and easier for users to figure out.

First, 16.5 is not as " length". It is as " Width". Second it can't mark as outside dimension because it will confuse with people. Outside dimensions is 36 inches length.

What I was commenting on was a difference in labeling between outside and inside dimensions. The outside length, measured left-to-right, is 36". The inside length is currently listed as 17.75", which seems to be the front-to-back measurement, not left-to-right.

If the 16.5" measurement were relabeled as length, and 17.75" relabeled as width, then it would follow the same pattern as the outside dimensions' labels which correctly lists 36" as the overall length and 22" as the overall width.

If "length" indicates the left-to-right dimension and "width" indicates the front-to-back measurement, then the listed dimensions are just inconsistent. It's certainly not my intention to cause any confusion and I hope this helps to clarify.

• (L) = 17.75 inches length--- Left to right
• (W) = 16.5 inches width---- Front to back

Outside Dimensions:

• (L) = 36 inches length-----Left to right
• (W) = 22 inches width-----Front to back

Good afternoon, the specifications of this product say: top mount-drop in.

Can this product be installed also as a undermount sink?

I would like to buy it but only if it can be used as a undermount sink.

Would you please let me know at your earliest convenience? Thanks!

Sorry, can not use undermount.
