I would like to put a swimspa on a steep slope with a raised deck. My plan is to add a 16' by 55' raised deck with a swimspa at one end with a vanishing edge. Can I do this and if so, can anyone give me an idea on how much more it would cost. I am interested in the Viking HZ DXL model; unless someone knows a similar style that would work. If anyone could give me a range of cost and swimspa manufacturers it would help me in the planning process.
