Hot tub footprint fit
Enter the measurements above to calculate hot tub footprint fit.
How the calculation works
V12 calculation: requiredWidth=tubWidth+2×serviceClearance; requiredLength=tubLength+2×serviceClearance; orientationA=requiredWidth≤patioWidth AND requiredLength≤patioLength; orientationB=requiredWidth≤patioLength AND requiredLength≤patioWidth; fitPass=orientationA OR orientationB. This is the implementation specification for this calculator.
Worked example
Example: Hot tub width = 210 cm; Hot tub length = 210 cm; Manufacturer service clearance = 5 cm; Patio width = 400 cm; Patio length = 500 cm. Result: Fits; Orientation B = Pass; Orientation A = Pass; Required Length = 220 cm.
