Under-Sink Space Guide for Quooker Reservoirs and CUBE

Your Quooker system lives under the sink — measuring your cabinet is the most important step before ordering.

Reservoir Dimensions

• PRO3: 260mm × 260mm × 360mm — fits almost any cabinet
• COMBI: 360mm × 360mm × 440mm — standard cabinet
• COMBI+: 360mm × 360mm × 490mm — taller, check height

CUBE Space

Adding the CUBE requires an extra 180mm × 180mm beside the reservoir. Make sure your cabinet has enough width for both units.

Extension Sets

If space is tight, extension sets (30-150cm) let you place the reservoir in a different cabinet or utility room.

FAQ

• Can the reservoir be mounted sideways? No — must remain upright for proper operation.
• Is ventilation needed? Yes — leave at least 50mm clearance on all sides.
