You are looking for pretty common items!

Have you gone to a Ferguson's or similar plumbing supply showroom? The brand I used is Franke.

As far as the soap dispenser, you need to get a NeverMT and put a big Costco sized bottle under the sink. You won't have to fill it for a very long time.

Skip the air gap, please. One time where the building code in certain areas is truly nutty.

I actually never heard of this air gap until I started on Houzz.

If OP is in California, s/he is required to have air gap. Just a couple other places in the entire U.S. that require them. Can OP tell us where s/he is located? That air gap thing is so antiquated. New DWs come with high loop hose which is better and replaces need for air gap.

The Kohler Artifacts faucet is my favorite, but it is a more traditional look. You didn't say whether you want traditional, modern, or in-between.

I am OP, but cannot figure out to edit my message so I am putting more info here. I am in CA, in sunnyvale city. I have lived in CA and never had a house without the air gap. I am looking for a modern look.

Thank you for the suggestion Chispa- will try that, we use seventh generation soap and it does not comes in big sizes, Since we use dishwasher too , one bottle last for quite a long.

OP - there is no need for an air gap due to the way DWs are made today with a high loop hose. That is why it is no longer required almost anywhere in the U.S. except California (where you are). You would only need to install the air gap if you were going to get inspected by a city inspector after a renovation. What people do in that case is install the air gap, do not install the soap dispenser. Then, after the inspection is done and passed, replace the air gap with the soap dispenser. That means one less hole, and no ugly air gap in your new kitchen..

I'm also in CA and had to put in another air gap when we just remodeled the kitchen. OP has a big enough sink that the air gap won't take up the space of anything else or be in the way. It is what it is.

I set up my sink fixtures just like they did in this photo:

I have been doing research for many years about reverse osmosis drinking water. I believe there may be some cause for concern. First, pure water does not occur anywhere in nature as far as I know. Pure H2O is very unstable and wants to bind with other minerals to become stable. That is why it is critical to make sure the faucet that is used is certified for R/O use. From what I have read, drinking pure water may leach important minerals from your body. That is why it is important to take supplements if you drink R/O water. This is a link to some unbias research by the World Health Organization. Health issues drinking Reverse Osmosis Water

I did not know that faucet had to be certified for RO use, will check your article, it is quite big and will need time to read it.

You will also need a sink faucet that is certified for use in California. Most are not. To find out if a faucet is allowed in CA, go to https://cacertappliances.energy.ca.gov (which is not working today, try tomorrow). Look for the brand and model in the database. If it is not there, the faucet is not permitted in CA.
