Quooker CUBE Setup Guide: What You Need Before Ordering

The Quooker CUBE adds sparkling water to your boiling water tap — but there are a few things you need before ordering.

What You Need for CUBE

The CUBE system requires:

• A Quooker COMBI or COMBI+ reservoir (not PRO3)
• Under-sink space: 180mm × 180mm extra next to the reservoir
• Access for CO₂ cylinder replacement

CO₂ Cylinders

We stock CO₂ cylinders (3KG and 4KG, 2-packs). Each cylinder lasts 3-6 months depending on usage. Ground shipping applies to CO₂ orders.

Setup Process

Professional installation is recommended. Your installer connects the CUBE to the COMBI reservoir and CO₂ line. See our installation guide.

FAQ

• Can I add CUBE later? Yes — but it's cheaper to buy the complete system upfront.
• Is CUBE noisy? A brief 3-second carbonation sound, similar to a coffee machine.
