There've been some threads on this, with as much variation as you might expect. To me, your answer is in your sentence "I use a sprayer all the time to clean the sink." Can you get by without one? Sure, I do with the help of an articulated faucet. Will you regret not having one? I'm going to guess "yes".

I personally couldn't imagine not having a spray but obviously people function without one.

I think the tool you are looking for would be rubber gloves since your hands would never touch the wet sponge - still I would miss being able to spray off any cleanser residue as it would take far longer with a sponge.

Thanks! I think I found this sink squeegee that works, so we're going spray-free. No sponge involved. Less water used. Works for benchtops as well.

I would want a faucet with sprayer at my kitchen sink(s). I also don't like the looks or function of a side spray.

I wouldn't live without one. I like it as part of the faucet, not as a side sprayer. To me, they are so functional. If I were you, I would change to a faucet with a sprayer included. The kitchen is a functional place. You want it to be pretty too, but it is a hard-working area. You need tools in the kitchen, not just "eye candy." IMHO ;)

I lived without a spray for almost one year- it's feasible. My sponges never get remotely gross, though, so wiping down the sink with a soapy sponge and then rinsing off with the same rinsed though sponge was not a big issue. I missed the spray the most when washing fruits and vegetables. I am back to having a side spray (Dornbracht Meta) and it's quite nice. If you can afford the splurge, go for it. If not, it's really not the end of the world, but do keep your sponge immaculately clean. Use the hottest of water and always rinse out the sponge with hot soapy water until it is clean. Let it air dry and replace it every other week- also pop it into the dw every few days.

I use a sprayer not only for rinsing off the sink sides, but also for rinsing food in colanders (e.g., beans, greens, cooked pasta). I would not want to be without a sprayer.

Remember that freebies aren't worth very much if they don't do they job that you need them to do.

I went my entire life without a sprayer and didn't miss it. I've had one now for 6 years and I cannot imagine how I managed without it, esp. with a deep sink with a grid. I use the sprayer probably 95% of the time I use the faucet for anything. Not only do you get an angle on things, but you get the added force of the spray. Now I wouldn't be without one. I prefer pull-down.
