Kitchen water taps fall into a handful of clear categories, from a standard mixer tap through to a multi-function system that dispenses boiling, chilled and sparkling filtered water from a single spout. The right type depends less on style than on how a household actually uses its kitchen tap day to day, whether that is simple hot and cold washing up, filtered drinking water, or replacing a kettle entirely with instant boiling water. This guide sets out the main types of kitchen water taps available in Australia, what each one actually does, and how to work out which combination suits a particular kitchen.
Key Takeaways
- Kitchen water taps range from simple single-lever mixer taps through to multi-function systems combining boiling, chilled and sparkling filtered water in one spout.
- Filtered water taps reduce chlorine, sediment and taste-affecting particles before water reaches the spout, and this filtration sits ahead of any boiling, chilling or carbonation stage.
- Boiling water taps remove the wait associated with a kettle by storing filtered water in a small, insulated tank kept near boiling point around the clock.
- Multi-function taps are commonly described by how many water types they deliver, from 2-in-1 through to 5-in-1 configurations, combining hot, cold, filtered, boiling, chilled and sparkling water in varying combinations.
- Alia Global builds across this full range, from its X51 boiling, chilled and sparkling system to its 4-in-1 filtered taps, so the choice comes down to which functions a kitchen will actually use.
What Are the Main Types of Kitchen Water Taps?
Most kitchen taps sold in Australia fall into one of several broad categories, and many taps combine features from more than one. Understanding the categories first makes it easier to compare specific models on the features that matter.
- Standard mixer taps, blending hot and cold water from a single spout with one handle
- Pull-out and pull-down taps, adding a retractable hose for extra reach around the sink
- Filtered water taps, reducing chlorine, sediment and odours before water reaches the spout
- Boiling water taps, dispensing near-boiling filtered water on demand from a small under-sink tank
- Chilled water taps, delivering cold filtered water without a jug taking up fridge space
- Sparkling water taps, adding carbonation to filtered water at the tap
- Multi-function taps, combining several of the above in one fitting and one spout
The remaining sections work through each of these in turn, along with how they are commonly combined.
Standard Mixer Taps: The Everyday Kitchen Standard
A standard mixer tap blends hot and cold water from the household hot water system through a single spout, controlled by one lever or handle. It remains the most common tap fitted in Australian kitchens, largely because it is straightforward, reliable and inexpensive relative to more feature-rich alternatives.
Most modern mixer taps use a ceramic disc cartridge, an upgrade on older washer-based designs, giving smoother operation and fewer drips over time. Some are also gooseneck in shape, with a raised, curved spout that gives more clearance for filling tall pots, while others sit low and compact to suit a smaller kitchen footprint.
A mixer tap on its own does not filter, chill or heat water beyond what the household hot water system provides, which is the main trade-off against the more feature-rich categories below.
Pull-Out and Pull-Down Taps: Extra Reach at the Sink
A pull-out or pull-down tap adds a retractable spray head on a flexible hose, extending well beyond the fixed reach of a standard spout. This makes it easier to rinse large pots, wash produce over a wider area, or clean the sink itself without repositioning items constantly.
Many pull-out taps offer two or more spray settings, typically a standard stream and a wider spray pattern, switched with a button on the head itself. This feature is commonly combined with a standard mixer tap, though it also appears on filtered and boiling water taps in Alia's range.
The main consideration with a pull-out design is bench and cabinet clearance for the hose mechanism, which a plumber can confirm as part of a standard installation.
Filtered Water Taps: Cleaner Drinking Water Without a Jug
A filtered water tap passes mains water through a cartridge before it reaches the spout, reducing chlorine, sediment and taste-affecting particles. This is separate from any boiling, chilling or carbonation function, and it sits ahead of those stages in a combined system.
Filtration cartridges are typically rated by throughput volume, so replacement frequency depends on household usage. Alia's F5000L cartridge, used across its boiling and multi-function tap ranges, is rated to 10,000 litres before replacement is needed.
A dedicated filtered tap suits a household that wants cleaner drinking water without the ongoing cost of bottled water or the bench space taken up by a filter jug, and it is the foundation that boiling, chilled and sparkling systems build on.
Boiling Water Taps: Instant Hot Water Without a Kettle
A boiling water tap dispenses near-boiling filtered water within seconds, because the water is heated and stored in advance, ready before the tap is even opened. A small, insulated tank under the sink holds water close to its set temperature, topped up by a heating element whenever the tank is drawn down.
Alia's instant boiling water tap range dispenses filtered boiling water across a 35°C to 98°C adjustable range, using its Bollente boiling unit and a touch-sensitive control panel. This removes the wait, the bench space and the repeated full reheats that come with an electric kettle.
Our dedicated comparison, instant boiling water tap vs kettle, covers the practical differences in more depth for a typical Australian kitchen.
Chilled Water Taps: Cold Filtered Water on Demand
A chilled water tap cools filtered water using a dedicated cooling unit, delivering cold drinking water directly from the tap and freeing up the fridge space a jug would otherwise use. This is usually paired with a boiling function in the one under-sink system, since both draw from the same filtered water supply, such as Alia's instant hot and cold water tap range.
Output temperature and flow rate vary by configuration. Alia's combined boiling and chilled systems deliver filtered water in the 4°C to 11°C range at a steady flow, drawing on the same filtration cartridge used for the boiling side of the system.
For a kitchen that mainly wants cold drinking water without the boiling function, a chilled-only configuration keeps the under-sink footprint smaller, though most households find value in having both from the same tap.
Sparkling Water Taps: Carbonated Water Straight From the Tap
A sparkling water tap adds carbonation to filtered water using a CO2 cylinder connected to the under-sink unit, delivering adjustable levels of fizz on demand. This removes the need to buy, store or carry bottled sparkling water, and it is usually combined with boiling and chilled functions in the one system.
Alia's sparkling water tap systems use a dedicated Fizz-X carbonation unit, compatible with a food-grade CO2 cylinder, and offer adjustable carbonation levels, from a light sparkle through to a fuller fizz. This suits households that want restaurant-style sparkling water without relying on single-use bottles.
The CO2 cylinder is a separate consumable from the water filter cartridge, and it is worth checking replacement cost and availability alongside the tap itself before ordering.
Multi-Function Taps: Combining Boiling, Chilled and Sparkling in One
Most modern kitchens combine several water types into a single fitting, avoiding the need for separate taps for each function. These are commonly described by how many functions they deliver, ranging from 2-in-1 configurations through to 5-in-1 systems that combine filtered, boiling, chilled and sparkling water alongside standard hot and cold mixing.
- 2-in-1 and 3-in-1 taps typically combine standard mixing with filtered or boiling water
- 4-in-1 taps, such as Alia's 4-in-1 boiling and chilled filtered water tap, add both boiling and chilled filtered water to standard mixing
- 5-in-1 taps, such as Alia's X51, extend this further to include adjustable sparkling water alongside boiling, chilled and standard mixing
The trade-off for combining more functions into one tap is a larger under-sink footprint, since each function typically needs its own tank, cooling unit or carbonation unit alongside a shared filtration cartridge. Our guide on how instant boiling and chilled taps improve kitchen efficiency looks at how this plays out in daily use.
Smart and Touch-Control Taps: Where Technology Meets Tapware
A growing number of kitchen taps now include a digital control panel, replacing the traditional lever entirely, particularly across boiling, chilled and sparkling systems. These typically use touch-sensitive buttons managed by an internal PCB, giving more precise control over temperature and function selection than a manual valve alone.
Alia's multi-function taps include a child-lock function on the boiling setting as standard, so the highest temperature output cannot be triggered by an accidental touch, alongside independent certification to AS3718 and WaterMark standards for Australian plumbing compliance. Our guide on how to use an instant hot water tap safely covers these safety features in more detail.
Digital control also opens up features that a manual tap cannot offer, such as an adjustable boiling temperature that spans a full range for different tasks.
How to Choose the Right Type of Tap for Your Kitchen
The right combination of features depends on how a household actually uses its kitchen, not on which system has the longest list of functions.
- Consider how often boiling water is needed. A household that makes tea and coffee throughout the day gets more daily value from a boiling function than one that rarely does
- Think about drinking water habits. A household already buying bottled or filtered water benefits from a filtered, chilled or sparkling tap more than one satisfied with tap water as is
- Check under-bench space and power availability early, since multi-function systems need more room and a dedicated power point
- Weigh up budget against function count, since each added function generally adds cost alongside its benefit
- Confirm installation requirements against the specific model, since footprint can vary across a range

Frequently Asked Questions
What is the most common type of kitchen tap in Australia?
The standard mixer tap remains the most common, blending hot and cold water from the household hot water system through a single spout and handle. Filtered, boiling, chilled and sparkling taps sit alongside this as additional categories that add function to the everyday mixer tap.
Do I need a filtered tap if I already have a boiling water tap?
Filtration is usually built directly into a boiling water tap, since the same filtered water supply feeds the tank. A standalone filtered-only tap suits a household that wants cleaner drinking water without the boiling, chilling or sparkling functions.
What does 4-in-1 or 5-in-1 mean on a kitchen tap?
These figures describe how many water types the tap delivers. A 4-in-1 tap typically adds boiling and chilled filtered water to standard hot and cold mixing, while a 5-in-1 tap extends this further to include adjustable sparkling water.
Can I add a boiling water function to an existing kitchen tap?
Generally not to the existing tap itself, since boiling water taps require their own tank, element and thermostat installed under the sink and connected to a dedicated spout. Most installations replace the existing tap entirely to fit the new spout and connections.
Do multi-function taps need more maintenance than a standard mixer tap?
They have more components, including a filter cartridge and, on some models, a CO2 cylinder, each with its own replacement schedule. The tap and its internal tank and element are otherwise largely maintenance-free between cartridge changes.
A Tap Type for Every Kitchen Routine
Choosing between the types of kitchen water taps comes down to matching function to routine. A household that mainly wants reliable hot and cold water is well served by a standard mixer tap, while one that drinks filtered water throughout the day gets genuine daily value from a boiling, chilled or sparkling system. Working through the categories in this guide, and checking installation requirements against the specific model, makes it far easier to land on a tap that earns its place in the kitchen every day.
