Calculation of water volume
Keep in mind that the water volume
increases with about 300 litres per
every decimetre added to the diame-
ter, which affects the time it takes to fill
and heat the hot tub.
D=Diameter
R= D/2
The water volume is calculated accor-
ding to the formula below. The measu-
rements are in metres:
Calculations
R x R x 3.14 x Water depth = Volume in m3 (or weight in tonnes)
Calculation of the number
of boards needed:
To calculate the number of side boards
needed, you can use this formula:
Use measurements in millimetres
B= The width of the side board,
excluding the tongue and groove.
D= Diameter
The centre of the side board is about
one centimetre outside the bottom of
the hot tub, so add another 20 mm to
the diameter.
D + 20 x 3.14 / B = The number of boards needed
