Applications
Under stairs wine cellar cooling
An under-stair cellar turns dead space into a purposeful wine feature, giving you practical storage and a clean, integrated look.
An under-stairs area is one of the most effective ways to use otherwise underused space. The main design challenge is the shape — angled ceilings, restricted access and small floor areas mean the cooling system, racking, lighting and services need to be coordinated early.
A well-planned under-stairs wine room can provide practical storage and a strong visual feature in a compact footprint. Encool supplies compact self-contained and split system options suitable for under stairs wine cellar cooling, with quiet operation and built-in humidity control on split systems.
See our guide to planning small wine rooms — including under-stairs conversions — or try the cooling calculator.

Common questions
Under stair cellar questions
Does a wine cellar need insulation?
Yes. The room should be built as a controlled environment. Poor insulation increases energy use, temperature instability and condensation risk.
Does a wine cellar need a vapour barrier?
A vapour barrier is strongly recommended for most controlled wine rooms. It helps reduce moisture movement into the cooled space and lowers condensation risk within the structure.
What happens if the wine room is not sealed properly?
Air leakage increases cooling load and humidity instability. It may cause condensation, temperature drift, short cycling and poor system performance.
