1. Use left faucet handle to select chilled sparkling, still or ambient water.


2. Use right handle to select and control regular hot and cold water.

4. With the detachable hose spray, you can easily clean fruit and vegetables as well as  your sink. Also supplies regular hot and cold water.


1. The magic is below your sink! The cooling SeltzaHub unit lives below your sink where it stores and chills sparkling water ready to be dispensed through the SeltzaTap faucet.

2. Simply by using a CO2 canister, connect it to the SeltzaHub by using the regulator and valves supplied in your shipment.

3. The touch buttons on the SeltzaHub adjust the desired cooling temperature and rate of fizziness.

Yes you can! With SeltzaTap faucet you can turn the left handle for chilled sparkling water and the right handle for regular hot and cold water.

SeltzaTap does not provide filtered water on its own, however it can be hooked up to your existing filtration system. Learn how through our installation guide.

The SeltzaHub unit stores and cools your seltzer water, dispensing it through the SeltzaTap faucet on demand. It lives under your sink and can adjust the cooling and fizziness of your seltzer water through the touch buttons on its exterior. Your CO2 canisters are connected to the unit to bring fizz to your chilled water.

SeltzaTap was created by engineer Donovan Watts, who found himself wishing for more than plain water from his kitchen faucet. 

“I had this thought every time I turned on my kitchen faucet. I already saw how much waste was created by soda makers and cans that wouldn’t hold bubbles long enough. I began to think there has to be a more convenient and sustainable way to enjoy sparkling water every day,” said Donovan. 

After two years of development and being installed in multiple homes, SeltzaTap has been fully tested and approved by families to become a household item that they can’t imagine life without.

The average person buys 156 plastic bottles a year for single use beverages and altogether Canadians create 3.3 million tonnes of plastic waste per year. SeltzaTap encourages drinking more water by providing more beverage options on demand,  without having to open up a single-use plastic bottle. One 5 pound CO2 cylinder will replace 100 one litre plastic bottles. The less plastics we purchase, the better it is on the environment. 

Take your SeltzaTap on the go with a reusable water bottle and add some lemon and berries for a fresh and sparkling beverage throughout the day! Seltza drink ideas available on our Fizzi Life blog.

SeltzaTaps can be fitted into new kitchens and also retrofitted into existing ones. To install a SeltzaTap, all that is required is space for the SeltzaHub and CO2 canister under the sink (see the technical overview here), an electrical outlet, and  minimum incoming cold water pressure of 50 psi is required.

Space requirements:
When the SeltzaTap faucet  is  universally designed and can fit standard North American kitchen sinks:
Height: 508mm. (20")
Width: 255mm. (13 1/8")
Depth: 50mm. (2")

The SeltzaHub is placed under the sink and requires:
Height: 370mm. (14 1/2")
Width: 185mm. (7 1/4")
Depth: 450mm. (17 3/4")

Space below the sink for a CO2 cylinder to be attached to the SeltzHub is required. While SeltzaTap is best outfitted with 20 pound cylinders that can last for 6-8 months, depending on your daily consumption of carbonated water, a SeltzaHub can be outfitted with smaller cylinders that can be purchased for countertop soda machines.

You may connect the SeltzaHub to softened water as long as the water supplied to the SeltzaHub meets the below criteria:

• Water connected to SeltzaTap must be potable.
• Minimum water pressure of 50 psi
• The Ph value of the water must be between 6.5 and 9.5 with no excessive salt.

SeltzaTap is delivered with installation materials and a clear manual. The installation guide can be found online here.

Aside from the CO2 bubbles, there is no difference between tap water and carbonated water!

While canned and bottled seltzer water has been called out for its added sugar, sodium and high rates of acidity, SeltzaTap sparkling water has no extra ingredients nor flavouring, making it equally as healthy as plain tap water.

As with anything in life, the key is moderation. Carbonated water without any additives, like SeltzaTap, can be ingested up to a liter per day. The daily recommended water intake is 8 glasses a day, we suggest 4 of those glasses be carbonated!

If you are prone to bloating or burping then it is suggested not to drink seltzer water before a big race or activity. 

While naturally carbonated beverages, like SeltzaTap do not contain any acidity or sugars, if you have sensitive teeth, it is recommended not to drink canned sparkling beverages where there can be additives and flavouring.
