At The Kitchen Sink
We get it. Kitchens aren't meant for jumping through hoops. Getting water that's filtered or hot enough for cooking and cleaning can be frustrating and time consuming.
Are you tired of breaking your back and wasting money to avoid using tap water? Let's face it. No one wants to work that hard for filtered drinking water. Wouldn't it be nice to get rid of that bulky water dispenser or stop looking for ways to keep your bottled water out of sight?
Are you fed up running the faucet, waiting for the water to get hot, then moving it to the stove or microwave to bring it to the desired temperature? It shouldn't be that complicated.
At AquaNuTech, we provide convenience on demand with an all-in-one faucet, so you can spend less time doubling your efforts and more time doing the things you love.
A full-flow, pull-down spray faucet that adds instant hot water and filtered drinking water to your kitchen tap. The compact configuration leaves plenty of undercabinet space to spare. It's a powerful all-in-one faucet for your home, RV or boat.

"Incredible asset in the kitchen! I didn’t truly realize how much I’d become addicted to the features of this faucet until we had it. The instant hot makes morning coffee and quick pasta making a breeze."
We love our 4N1 faucet and tank system! The faucet itself is a beautiful piece added to our kitchen with a multipurpose function that fits all our family needs! As parents we are always sanitizing our bottles, toys, etc. ever day with our 198 degree instant hot water. Under the sink, it is a very small tank taking up little room leaving lots of space. Thank you so much AquaNuTech, looking forward to future products!
“Install was super easy! Love having filtered water and hot water all from the same faucet!”
“What an incredible company! When it came time to install they walked me through step by step on the phone and via text. They were so patient with me as I was determined to install without hiring a plumber. With their guided help I did just that! Now I have their amazing product with instant hot water and cold purified water all hooked up. Thank you Tim! I highly recommend this companyand their products!”
“We absolutely love this faucet. First off, the style of it is very sleek and modern and really compliments our kitchen. Having filtered water at the faucet is very handy.... but the best thing about it is that the instant hot water is extremely handy. If you are looking for a functional and stylish faucet look no further. AquaNuTech has been amazing to work with.”
