The SQUARE suitable for 3-4 adults. If compactness and comfort are your key criteria then this is the perfect spa for you. The Solana SZ Square has been designed to fit even the small sites without being overbearing. Three generous sculptured seats with fully recessed jets provide a couple with a choice of stretch out positions in absolute comfort. In spite of its compact exterior there is ample room inside for the grandchildren or even another couple when it's time to entertain at home.
