I'm a righty, husband is a lefty. Faucet is in the center, soap dispenser is on the left, air switch is on the right close to our drain (our farmhouse sink drain is all the way on the right) You get used to the placement no matter what your dominant hand is.

Make sure the hole for your air switch is farther away from the faucet handle. You don’t want dripping hands from the faucet to be dripping into the air switch constantly.

thx everyone! Great point about water dripping into the air switch. I was also worried about the safety of the air switch, but I'm not sure there\'s a more safe place or a less safe place as far as kids or someone touching the switch if someone had to stick their hands down the drain for if something like a fork fell in the drain...

Sabrina, why should the air switch be closest to the dominant hand? That's what the designer said about the water filter. I was also thinking placement might be according to what side of the sink we put the drain. It's an offset drain with just one drain, single basin. I was thinking of having the drain in the back right versus the left front (i believe that's how it's set up) so that i can tuck the garbage disposal, water filter... everything in the back corner, but the plumber mentioned that to me and I can't remember how it makes a difference at the moment.

From left to right -- water filter - air gap - faucet - air switch - soap dispenser.

My drain is in the right-rear.

chispa, do u like your configuration? It seems like the soap dispenser on the right is a good idea as what I plan on putting in mine is dish washing soap, not hand soap and access to soap while doing dishes would be good in that case. When getting water to drink I guess I don't care what side it's on and in my house if I were filling water to heat up pasta on the stove that's the stove side. It's further from the living area, though, but with an island we'll have access from other areas.

heck, though, it's as if I'm talking about a 6' sink! :) In the end DOES it really matter?

PS-do u ever have probs like mentioned with the air switch since it's not at the end? thx!

Ok, I looked under my sink and the plumbing is closer to the right side so that's why the plumber said it'd make more sense to have the garbage disposal and the filter all tucked away on that side so i had the other half of the sink free. So, in that case, I'll have to decide if I do the air switch first to not get it wet or the soap dispenser for a little more symmetry.

choice 1 left to right= air switch - soap dispenser - faucet - water filter

choice 2 left to right = soap dispenser - air switch - faucet - water filter.

i'm sure i could find a pic if i looked hard enough

mama, I have hand soap in mine and keep a small refillable bottle of dawn sitting in the sink. Although my Never-MT has been acting up and isn't putting out any soap at all!

No issues with the air switch at all. It is 6-1/4 inches from the faucet (center to center), BUT I have my faucet handle turned to the front. In any case, my husband manages to get water everywhere when he washes stuff and he never gets water on the air switch! My sink is 30" x 18" x 10"

As far as the water filter, next time I get to do a kitchen, I might think about placing it in the prep sink. Even better might be to just have the faucet in the prep sink run off a water filter ... would probably have to look into volume and capacity of the filter.

thx! If water did get on air switch would it leak into cabinet?

I like my filter on sink. It fills pots and is faster than fridge water

I have never had a problem with air switches and normal water splashing around a sink.

What is your faucet?

I really like having my faucet handle towards the front. It helps a lot with reducing dripping around the faucet, specially with others in the house who wouldn't ever think to wipe around the faucet area!

Both of our kitchen sinks have the air switch on the right and soap dispenser on the left for hand soap as I am constantly washing my hands while cooking. When we remodeled I purchased a separate Waterstone hot/cold filter faucet which I didn't end up using because I decided that I didn't need an instant hot water dispenser. Instead we put a filter on the prep sink cold line for cooking and filling drinking glasses and pitchers. We were also able to tee that line off to the ice maker. I signed up for Amazon auto-ship so I don't forget to change the filter.

Chispa, I never thought about water dripping! I will have to look at my faucet when I get home but I think it is like the one that Shannon posted with the handle on the side so water will drip on to the countertop. I cannot picture what one looks like with a handle in front. I was going for a long so that I could rinse vegetables well. I got mine off of Amazon and it stretches Ft. It does not have the magnet to go back to its original position though so that was my only original worry about the faucet that I bought. It had great reviews but you never know with reviews

“I cannot picture what one looks like with a handle in front.“

Here is a link to a thread on this topic. With this faucet handle placement, you do away with water, soap scum, and hard water minerals from dripping hands landing on the counter under the faucet.

”I'm not sure there's a more safe place or a less safe place as far as kids or someone touching the switch if someone had to stick their hands down the drain for if something like a fork fell in the drain...”

You could also consider a “batch feed disposal”, in which there is no switch. The disposal is operated by a cover which doubles as a sink strainer and stopper. Push the cover in, the disposal starts. Pull the cover off, the disposal stops. The disposal can only operate with the cover on. There is no separate switch. There are pros and cons of each type of disposal - the “continuous feed“ which is what an air switch operates that you are talking about, and the “batch feed” which is what I just described. Read up on them if you are interested. I myself have a 1 hp batch feed disposal which I have had for many years because I too was concerned about my kids. Now they are grown but I still prefer the batch feed style. One caution is that my 1 hp batch feed disposal is large and takes up more room under the sink.

This very quick video shows the cover of the Waste King batch feed disposal turning it on, turning it off, and acting as a stopper or as a strainer so you can see how the disposal works (though mine doesn’t have the strainer thingy shown at the very end. That strainer makes no sense since the black cover acts as the strainer).

I've gotten behind but wanted to thank u all for your comments! i ended up wanting balance and some of it had to do with picture window being more open... so i put the shorter soap dispenser on the left, then button, faucet, then filter faucet. Plumber comes Tues or sooner so I'll look more at the other link that u provided regarding the handle for faucet in front. I started reviewing earlier and I can see what u mean. I think my faucet can do that. Prob easy to unscrew and twist to the side if i wanted to later? I'll be there with plumber watching and will talk with him about it. thx again!
