That is only a filtration faucet, not a regular kitchen faucet. Take a look at Waterstone's website and you can see the difference.

To amplify, you linked the filtration faucet from the Towson suite. Waterstone's products are organized by "suites" that include regular faucets, filtration faucets that get installed next to a regular faucet for instant hot and/or cold filtered water, soap dispensers, air switches, etc. that match one another. You can see the whole suite by clicking on the link that is contained within the link in your post. I almost went with the Towson faucet but opted for a pull down instead, so I got the 5600 PLP. The Towson is great looking though and Waterstone faucets are fabulous.
