The build and technicalities of a hot tub

The spa shell is basically the moulded interior that contains the seating.The
frame of the spa supports the spa shell and is generally made of either treated
timber, metal or synthetic struts. It is important for the long-term integrity of
the spa structure.
The spa cabinet is the outer cladding that protects the inside of the spa from
the elements and provides the aesthetic finish to the area below the shell.
Cabinets are most commonly made from timber such as cedar or teak, or
synthetic materials which replicate the look of wood.
Spas are supplied with an insulated hard cover that is filled with either high
density foam or polystyrene. This is then wrapped in a sealed waterproof
plastic and the final covering is made of vinyl on the outside to protect the
cover from the elements. The purpose of the cover is to keep debris out of
the water, to keep the spa safe by preventing unauthorised access, and to
insulate the top area of he spa against heat loss. Most spa covers range from
2” (5cm) to 4” (10cm) in thickness.
The pumps in the spa provide 3 main functions:
• To pump the water through the plumbing system to the jets which will
convert the flow into a massaging action.
• To pump water through the heater to run heat cycles.
• To pump the water through the spa filters to run clean up cycles.
