Aquatap Ultimo Launch: A 6-in-1 Boiling Water Tap with Sparkling and Chilled Water

The Aquatap Ultimo 6-in-1 boiling water tap combines the functionality of a boiling water tap, chilled water tap, and sparkling water tap into one complete kitchen water system.

Aquataps launched the Aquatap Ultimo on 13 March 2026 — a complete 6-in-1 kitchen water system delivering boiling, chilled, and sparkling water from a single tap, powered by one compact under-sink unit.

There is a moment in most kitchens, usually around 7am, when the worktop tells the story of how complicated water has become. The kettle. The filter jug. The sparkling water maker sitting at an angle because there is not quite enough room for it. The standard mixer tap that handles everything else but none of it particularly well.

The Aquatap Ultimo was designed around that moment.

The Aquatap Ultimo is a 6-in-1 digital boiling water tap and complete under-sink water system — one tap, one compact unit, and everything a modern UK kitchen needs from its water supply, from a single fixture.

Why 6-in-1 Taps Are Replacing Kitchen Appliances in the UK

The boiling water tap has been part of premium kitchen design for years, but the category is evolving rapidly. Homeowners are now looking beyond a standard boiling water tap towards integrated systems that also function as a chilled water tap and sparkling water tap — combining multiple appliances into a single fixture with one under-sink unit.

Three converging trends are driving this shift.

First, modern kitchen design favours minimal worktops — fewer visible appliances, more hidden storage, and cleaner lines. A kettle, filter jug, and sparkling water maker quickly consume valuable space that most kitchens cannot spare.

Second, pressure to reduce single-use plastic continues to grow. Households that regularly buy bottled sparkling water are increasingly switching to sparkling water taps that eliminate bottles altogether while improving the quality of everyday drinking water.

Third, the technology has matured. A 6-in-1 system can now be installed within a standard kitchen cabinet, delivering boiling, chilled, and sparkling water from one compact, integrated unit — without complex plumbing.

The Aquatap Ultimo sits at the centre of this shift. It is not a premium extra — it is the natural evolution of the modern kitchen water system.

Is a 6-in-1 boiling water tap worth it? For most households that use a kettle daily, rely on filtered water, and buy sparkling water — yes. The Aquatap Ultimo replaces your kettle, filter jug, sparkling water maker, and standard mixer tap in one installation from £1,249.99 inc. VAT. The upfront cost is balanced against the combined cost of these appliances, ongoing spending on bottled water, and the long-term convenience of instant boiling, chilled, and sparkling water from a single tap.

Boiling Water Tap, Sparkling Water Tap, Chilled Water Tap — One Tap or Three?

When people search for a sparkling water tap or a chilled water tap, they are usually looking for the same thing: a single system that replaces the kettle, the filter jug, and the bottled water habit in one go. The question is which type of system gets them there — and how completely.

Dedicated chilled and sparkling water systems do exist. These units focus purely on delivering filtered chilled still, filtered ambient, and carbonated water — without a boiling function. They suit kitchens where instant hot water is not a priority, or where a separate boiling tap is already installed. For the right setup, they solve the cold water problem well.

The boiling water tap category takes a different approach — and has been expanding its scope steadily. A 4-in-1 boiling water tap covers instant hot water and filtered cold alongside standard hot and cold, replacing the kettle and improving tap water quality. A 5-in-1 boiling water tap goes further, adding either chilled sparkling or chilled still water — a meaningful upgrade, though it typically leaves one gap remaining.

The Aquatap Ultimo closes every gap in a single system. As a 6-in-1 tap, it delivers instant boiling water up to 98°C, chilled sparkling water on demand, chilled still water at 3–10°C, and filtered ambient water at room temperature — alongside standard hot and cold. Unlike a dedicated chilled or sparkling system, it also replaces the kettle entirely. Unlike a 4-in-1 or 5-in-1 tap, it leaves nothing to add for cold water.

One tap. One compact under-sink unit. One installation that covers every water function a modern kitchen needs.

Who Is the Aquatap Ultimo For?

Before the specifications, it is worth being precise about which households and professionals this product is designed for — and where it may not be the right fit.

The Aquatap Ultimo is well suited to homeowners undertaking a kitchen renovation or new kitchen installation who want a single premium tap solution rather than a collection of individual water appliances. It suits households that boil the kettle several times a day, regularly purchase bottled sparkling water, or find that tap water quality — particularly in hard water areas — affects the taste of drinks and cooking. It suits kitchen designers, interior designers, and property developers who need a complete, high-specification kitchen water system to specify for clients without the complexity of multiple under-sink units.

For families with young children, the Ultimo’s 3-second press-and-hold activation for boiling water and cool-touch insulated spout make it meaningfully safer in daily use than a kettle on the worktop — a genuine practical advantage, not just a feature.

It is not the right choice for every kitchen. Properties with mains water pressure below 1.5 bar cannot run the system reliably. Under-sink cabinets with less than 50mm of clearance on all sides of the unit will restrict the chiller’s ventilation and reduce performance — and failures caused by inadequate ventilation are not covered under the Aquataps warranty. Both are straightforward to check before purchasing.

What Is a 6-in-1 Boiling Water Tap?

A 6-in-1 boiling water tap is a kitchen tap that delivers six distinct water outputs from a single fixture. The Aquatap Ultimo provides:

• Filtered boiling water — up to 98°C, instant, ideal for tea, coffee, cooking, and food preparation
• Filtered chilled sparkling water — carbonated on demand via an integrated CO₂ system, chilled to 3–10°C
• Filtered chilled still water — maintained at 3–10°C by a built-in Ice Bank chiller, for clean cold drinking water
• Filtered ambient water — filtered drinking water at room temperature, improving taste by removing chlorine and contaminants
• Unfiltered hot water — standard hot supply from the household system, for everyday washing and kitchen tasks
• Unfiltered cold water — standard mains cold water for general kitchen use

In practical terms, the Aquatap Ultimo delivers boiling, chilled, and sparkling water functions within a single kitchen fixture.

By comparison: a 4-in-1 boiling water tap provides instant hot water, filtered cold, standard hot, and standard cold. A 5-in-1 boiling water tap adds either chilled sparkling or filtered ambient — but not both. The Aquatap Ultimo delivers all six, making it a complete kitchen water system rather than a tap with a single added function.

The practical gap between a 4-in-1 and the Aquatap Ultimo is significant. With a 4-in-1 system, instant hot water and filtered cold are covered — but chilled drinking water still requires a refrigerator or separate chiller, sparkling water still requires a countertop appliance or bottled supply, and filtered ambient water at room temperature is not available at all. The Aquatap Ultimo removes all three remaining requirements in a single installation.

What Appliances Does the Aquatap Ultimo Replace?

This is often the question that puts the price into perspective. The Aquatap Ultimo replaces four separate kitchen appliances — and eliminates one ongoing purchase habit:

• The electric kettle — replaced by a boiling water tap delivering instant filtered hot water up to 98°C, on demand
• The water filter jug — replaced by filtered ambient water at room temperature, available directly from the tap. Clean, great-tasting filtered drinking water without a jug to fill, store, or remember to replace
• The sparkling water maker or standalone sparkling water tap — replaced by an integrated sparkling water tap function producing chilled carbonated water on demand
• The standard mixer tap — replaced by the Ultimo’s standard hot and cold unfiltered functions
• Bottled water — whether still or sparkling, the Ultimo eliminates the need for bottled water entirely, producing filtered ambient, filtered chilled still, and filtered chilled sparkling water on demand from the tap

The cumulative effect on the worktop is immediate — no kettle, no jug, no countertop appliance. But the environmental impact is equally significant. A typical UK household that regularly buys bottled water — still or sparkling — can generate hundreds of single-use plastic bottles per year. Switching to an integrated kitchen water system removes that waste at source, not through recycling but through elimination. Combined with the removal of the filter jug and its plastic cartridges, the Aquatap Ultimo represents a meaningful reduction in single-use plastic consumption — not as a marketing claim, but as a direct consequence of how the system works.

In hard water areas, the nano-phosphate filter also protects the boiler from limescale build-up — extending system life, reducing the likelihood of early replacement, and maintaining drinking water quality over time.

How Does the Digital LED Control System Work?

The Aquatap Ultimo uses a precision knurled dial with integrated LED colour indicators. Each water function is assigned a distinct colour, giving immediate visual confirmation of what is about to be dispensed — a design approach that eliminates the confusion common in multi-function taps with complex lever systems:

• White LED — standby mode, system is powered and ready
• Green LED — filtered ambient water at room temperature
• Blue LED — filtered chilled still water (3–10°C)
• Light Blue LED — filtered chilled sparkling water
• Red LED — filtered boiling water up to 98°C

Dispensing boiling water requires a deliberate 3-second press-and-hold — a safety mechanism that prevents accidental activation, particularly important in households with children or in busy kitchen environments. The spout is cool-touch insulated throughout, so the exterior remains safe to handle even at full boiling water flow. These are not incidental features. They are the design decisions that determine whether a product is genuinely usable every day.

Aquatap Ultimo Technical Specifications

The integrated boiler and chiller unit is designed to fit inside a standard kitchen cabinet at 372 x 242 x 422 mm, weighing 12.5 kg. By combining both systems in one appliance rather than two, it minimises under-sink space requirements while simplifying installation. Key specifications:

• Boiler capacity: 2.4 litres — approximately 8–10 cups of boiling water per cycle
• Maximum boiling temperature: 98°C (adjustable 60°C–98°C, accurate to ±0.5°C)
• Boiler reheat time: approximately 8 minutes
• Chiller capacity: 2.2 litres — maintained at 3–10°C
• Cooling performance: 11.5 litres per hour below 10°C
• Power supply: 220–240V, 1.5 kW, standard UK 13A plug
• Water pressure required: 1.5–5.0 bar
• Tap hole: 35mm | Tap height: 306.7mm | Reach: 222mm | Spout rotation: 90°

The 2.4-litre boiler capacity is worth putting in context. For a household of two, a single boiler cycle covers a full morning routine — multiple rounds of tea and coffee — without needing to reheat. For a household of four, one cycle handles breakfast with capacity remaining. The 8-minute reheat time means the system recovers well before the next peak demand period.

What Filter Does the Aquatap Ultimo Use?

The Aquatap Ultimo uses a nano-phosphate filter installed under the sink alongside the boiler-chiller unit. The filter serves two distinct purposes: it protects the boiler tank from limescale accumulation — particularly important in hard water areas across much of the UK — and it significantly improves the taste and safety of the drinking water the system produces. Independently tested contaminant removal rates:

• Chlorine: 99.5% reduction — improves taste and removes the most common tap water complaint
• Lead: 98.4–99.2% reduction — relevant in older UK properties with legacy pipework
• Arsenic: 86.7–97.8% reduction
• Iron: 99.5% reduction — addresses discolouration and metallic taste in drinking water
• Manganese: 98.7% reduction
• Trichloromethane: 95.78% reduction

Filter replacement every six months is a condition of the Aquataps warranty — not a suggestion. Aquataps offers a filter subscription service that automates the delivery schedule, removing the need to track replacement intervals manually.

Is 98°C Considered Boiling Water?

Yes. While water boils at 100°C, most premium boiling water taps deliver water up to 98°C for safety, efficiency, and everyday practicality. At this temperature, the system avoids excessive steam and energy use while remaining indistinguishable from fully boiling water for tea, coffee, cooking, and food preparation. The Aquatap Ultimo is adjustable between 60°C and 98°C, so the output temperature can be set to suit the household.

How Easy Is the Aquatap Ultimo to Install?

Straightforward — and Aquataps makes it even easier. The Aquatap Ultimo is designed to be installed by any competent DIYer comfortable with basic under-sink plumbing, and Aquataps provides a detailed step-by-step video installation guide that walks through every stage of the process clearly. Most customers complete the installation without a plumber.

What you need before you start: a 35mm tap hole in the worktop (or a suitable location to drill one), a minimum water pressure of 1.5 bar, at least 50mm of clearance on all sides of the under-sink unit for ventilation, and one standard UK 13A socket under the sink. That is all the system requires — one electrical connection, one water connection, and the installation video to guide you through every step.

Professional installation is also available via the Aquataps installation service for those who prefer a fully managed setup. Either way, the system is designed to be running the same day it arrives.

Warranty, Availability and Price

The Aquatap Ultimo carries a 5-year warranty on the tap and a 2-year warranty on the integrated boiler and chiller unit. It is available in four premium finishes — Polished Chrome, Matt Black, Brushed Nickel, and Brushed Brass — each sharing identical specification and performance. The finish choice is purely aesthetic.

At £1,249.99 inc. VAT, the Aquatap Ultimo is priced to compete directly with established premium brands in the UK kitchen tap market while delivering a more complete water system — instant hot water, filtered chilled drinking water, and on-demand sparkling water — for the price. Free next-day delivery is available to UK mainland addresses on orders placed before 1pm, supported by UK-based customer service Monday to Thursday 9am–5pm and Friday 9am–4pm.

The worktop moment at 7am does not have to be complicated. Order today. Use it tomorrow.
