Top 10 Questions to Ask


1. How are your spas insulated?

  • Only stick with a spa manufacturer that makes a non-foam filled spa, do not go with a foam filled spa.

    A foam filled spa costs more to fix and does not provide any energy savings. The sealed air non-filled units will allow easy access to the pumps and spa for service purposes and it is economically savvy.

2. What materials do you use to construct the shell of the spa?

  • Stay away from co-extruded materials that rely on foam for their structural support. These spa shells are made with acrylic and ABS which is an inferior way to construct spa shells. The best spa shells are made with acrylic and backed with 3 layers of hand-rolled fiberglass. They maintain their life better and they last longer.

3. What type of warranties do you offer with your spa and spa cover?

  • Manufacturers should offer at least a 25-35 year warranty on the structure of the spa. The spa cover should come with at least a 3 year warranty. Beware of lifetime warranties! Many states have specific laws stating what a lifetime warranty is, which is usually 7-9 years.

4. What type of filtration system do you use?

  • While there is no golden rule for what type of system to use, a pressure side filtration system is generally more efficient. They filter more water per hour than their suction side counterparts. All the water that travels through the pump is forced through the filter element, instead of half the water going through the filter and the other half going through a bypass. The pressure side also usually only needs one filter cartridge, thus reducing your costs when it comes replacement time.

5. Do you offer an Ozone system with your spas?

  • An Ozonator will give you the additional sanitizing action necessary to cut down on chemical usage, cost, and strong chemical odors. Make sure the Ozone is integrated with an injection system, to ensure that it is in contact with all the water for a longer period of time.

6. What is the density of the foam in your spa covers?

  • The density of your cover should be at least 1.5 lb. If it is more than 1.5 lb. check its weight because sometimes the cover will be very difficult to lift.

7. What types of seating do your spas have?

  • Have the salesperson explain the various seating that they offer and if they have muliti-level seating. Sit in the seats of the model you are considering and check the ergonomics of each seat. Do they contour your body? Are they comfortable? A "wet water" test is wise to do in order to determine if the depth of the seats works for you and if the shape of the seats keep you from floating.

8. What kind of jet formations do you have in your spas?

  • Get inside the spas and get a feel for where the jets hit your body. Make sure they hit the areas that you desire so that you will receive the hydrotherapeutic benefits. Remember that it is the quality of the jets rather than the quantity.

9. Is your control panel self-diagnostic?

  • A self-diagnostic control panel will recognize internal and external problems that your hot tub may have. It is not only helpful for service people, but it also reduces the cost of servicing your spa because the problem is already diagnosed.

10. Are there additional features or options that allow me to customize my spa?

  • Check to see if the manufacturer offers LED lighting or waterfall jet features. Also, look at the skirting styles and colors that they have available. Make sure that it is of good quality and is appealing to the eye.
