Bob has a few things for you to consider BEFORE you buy your hot tub…


Bob’s Rules for Buying a Hot Tub


#1 Always buy a spa that has a Non-Computer Control System

  • There is nothing on a spa that requires a computer to operate.
  • The only one who benefits from spa computers is the repairman.


#2 Always avoid buying a spa with a 2-Speed pump

  • They are noisy when you’re trying to relax in the spa and can be heard inside the house.
  • They overheat the water during the summer time.
  • They are more expensive to operate.


#3 Always buy a spa that circulates the water all of the time

  • Stagnant water is usually unhealthy.
  • Stagnant water requires more maintenance. (more chemicals & more time)
  • Turning a pump off and on reduces the pump life.


#4 Always buy a spa that pushes the water through the filter

  • No correctly engineered water filtration system sucks through the filter. (It’s called a pump not a sucker)
  • Suction type filters require more cleaning maintenance and expense.


In these short videos Bob answers common questions people have before buying a hot tub or spa.


How Much Does it Cost to Run a Hot Tub?

Pumps and heaters are the primary source of energy consumption on a spa.

How Many Jets Should a Hot Tub Have?
