The Billabong Plunge Slimline 4.2m x 2.6m trims the plunge concept into a slimmer footprint, which is handy when the pool needs to fit beside walls, fences or compact patios. This biggest 4.2-metre size gives the plunge format its most flexible daily-use layout in the range. Because the design is so direct, it pairs naturally with paving, screening and compact planting without making the outdoor area feel crowded. With a near-even depth of about 1.6 metres, the water feels consistent from end to end, which suits easy floating, cooling off and simple everyday use. The narrower 2.6-metre width makes it easier to fit into tighter layouts without giving the yard a cramped or overbuilt feel. For North Queensland buyers dealing with a narrow footprint, this range gives you a practical way to bring water, shade and relief into the yard.
