One of the things I said when we first looked at this house was something along the lines of, "If we buy this house, that faucet is going to be the first thing we replace." We bought the house and (of course) almost two years later that faucet was still in my kitchen, driving me insane on a daily basis.
It wasn't such a terrible faucet, it's just that in our previous home I had a beauty of a faucet, a Kohler Fairfax. I loved it because the pullout spray design meant there wasn't an extra implement at my sink (raise your hand if you hate the standalone sprayer thingy), which visually cleared up the space. The vintagey style on the handle was so adorable and it just worked so freaking GREAT goshdarnit. It looked like this:
In this new(ish) house I wanted a faucet with a higher clearance. I settled on another Kohler product: the Bellera.
It has the same pullout spray (LOVE, makes it easy to clean up the sink or fill a container) and a really nifty "pause" function, which is super handy when I'm watering plants (you turn on the tap, push the button and you can carry the sprayer across the counter to a plant or a pitcher or whatever, without having to go back and turn the tap on). The single control makes it really easy to wash my hands when they're covered in salmonella-laden gunk.
It also freed up a pre-drilled hole in my countertop where a sprayer used to be, so I stuck a soap dispenser in there, which let me get rid of the freestanding pump I'd been keeping on the counter.
A new faucet and soap dispenser wasn't cheap (but it WAS my birthday present!). It also had the really unexpected result of making me feel like I'd done a mini makeover in my kitchen. It's just a faucet and soap dispenser, I KNOW, but it did! They're high-touch items I look at and use ten or fifty times a day and I just love how they both look and how much simpler, well-designed, and efficient they are.
