Types of Water Mixer Taps

In New Zealand homes and commercial spaces, mixer taps have become a standard for their ability to blend hot and cold water through a single spout. But not all mixer taps are created equal. From basic single-lever designs to 3-way models with built-in filtration, and premium systems that dispense boiling, chilled or sparkling water, the options are broader than many expect.

Learn the different types of mixer taps, how they work, and why more designers and homeowners are choosing multifunction taps like those from Billi. With more than 30 years of innovation, award-winning design, and eco-conscious technology, Billi NZ is a leader in the evolution of tapware.

How Mixer Taps Simplify Everyday Water Use

Mixer taps combine hot and cold water streams into a single outlet, offering precise control over temperature and flow through just one lever. Tap hot or cold buttons to change the temperature. Lift up or down to start the flow of water. This simplicity makes them both efficient and intuitive.

Behind the lever is a compact internal mechanism that runs separate hot and cold channels. In more advanced systems, additional water lines carry filtered, sparkling, or boiling water.

Billi takes this to another level with underbench units that incorporate heat exchange and eco-intelligence systems, capturing waste heat from chilled water to preheat boiling, and learning usage patterns to minimise energy consumption.

Standard Mixer Taps and Where They Fit Best

Standard mixer taps are the most common type found in New Zealand homes. They do one job well, deliver hot and cold water through a single spout. They’re ideal for:

• Budget-conscious renovations
• Spaces without filtration or water feature requirements
• Bathrooms or secondary sinks

While they’re simple to install and maintain, they don’t provide filtered, boiling, or chilled water. For those who want more from their kitchen or office setup, these limitations can become obvious over time.

3-Way Mixer Taps for Functional Kitchens

A 3-way mixer tap offers a practical upgrade by incorporating filtered drinking water alongside hot and cold mains supply. This design eliminates the need for a second tap or bench-mounted filter unit.

Ideal for busy households and compact kitchens, 3-way taps help reduce clutter while delivering:

• Cleaner, better-tasting water
• Separate outlets for filtered vs. unfiltered supply
• Simple maintenance with Billi’s swing-change filters

The Billi Home FT range offers elegant, space-saving solutions that meet both health and aesthetic priorities. For families or workplaces that prioritise hydration and sustainability, a 3-way tap is an easy win.

Multifunction Taps That Replace Multiple Appliances

The Billi Home BCS range includes 5-way multifunction mixer taps that are the most comprehensive solution available. They combine:

• Mains hot and cold water
• Instant chilled water
• Instant boiling water
• Sparkling water

In essence, it replaces the kettle, water cooler, and soda machine, all from one compact unit. The underbench system is space-saving and requires no ventilation, making it ideal for minimalist kitchens and shared office environments.

Key features include:

• Safety switch for boiling water to prevent accidental use
• Eco-Intelligence® system that reduces power usage based on your habits
• Heat exchange technology that reuses energy from the chilling process
• Quiet operation and compact underbench units
• Multiple finish options including chrome, matte black, brushed, and rose gold

Recognised with a Good Design Award, and certified under Global GreenTag and WELL Building standards, this tap aligns with the needs of eco-conscious architects, specifiers, and homeowners.

How to Choose the Right Mixer Tap for Your Needs

Not sure which mixer tap is right for you Consider:

1. The available underbench and bench space
2. Your daily water needs (e.g. filtered, boiling, sparkling)
3. The number of users in the household or office
4. Design integration (finish, lever style, spout arc)
5. Maintenance preferences and energy efficiency goals

Billi’s multifunction taps require slightly more installation planning than standard ones, but their compact designs mean less underbench space is used compared to having multiple appliances. For those focused on future-proofing their kitchen or meeting wellness targets in commercial fitouts, the multifunction tap is an excellent investment.
