The Answers to the Most Common Hot Tub Questions

A hot tub is a large purchase, very similar to a car. There are many questions out there and you want to be sure to be prepared and know as much as you can before shopping and before we bring one out to your back yard. It is all a learning experience, but you will find out owning a Hot Spring or Caldera Spa is way easier than you originally thought! Scan today’s blog post for questions that you need answered!


What do I need to prepare before installing my hot tub?
To install your hot tub, you only need to worry about three things: a solid, level base to stand it on, to have the proper electrical requirements ready (ask your dealer for further information), and a hose to fill it up with – it really is that simple. If you plan to build a deck around your new spa, there will be the added consideration of access to the component door for servicing, so do bear that in mind when planning and preparing your base. Here at Hot Spring – Lacrosse, we offer free site inspections to make sure your space is ideal for you new hot tub, and to offer advice if need be.
How am I supposed to move/ install my hot tub?
This part is very simple… YOU DON’T!!! All of our hot tubs have delivery/ set up included in the price! Hot tubs are extremely heavy and require some special equipment to help the delivery go as smoothly and efficiently as possible.

How long will it take my hot tub to heat up?
Awesome question, but the answer varies depending on the brand. With a Hot Spring or Caldera hot tub, it will take between 8-10 hours to heat up initially, but will remain it’s set temperature for the whole fill. Our spas are very smart and know when the heater should kick on and when it is okay to power down.

How much will my new hot tub cost me to run?
Again, this answer can vary depending on the brand and the size of hot tub you go with. With our calculations on the biggest hot tub we sell (seats 8 people) in the freezing Wisconsin winter, that tub cost $24 per month to run. In the Summer, it only cost $8. When searching for the right hot tub, take energy efficiency DEEPLY into consideration!

How often do you drain a hot tub?
Depending on the sanitizing system you go with can play a roll on how often you drain and refill your spa. If you use the enhanced shock (chlorine) system, the bromine system,the Silk Balance system, or the BaquaSpa (hydrogen peroxide based) system, you will generally drain and refill once every 6 months. If you have a Salt Water hot tub (exclusively with a Hot Spring) you will only need to drain once a year.

Water Care
What does an Ozone Generator do?
Introducing Ozone to the spa water after the heater as part of the circulation system is quite normal. The Ozone generator creates very high levels of ozone which in turn oxidizes bacteria in the circulation system. If you do not have an Ozone system then you will use more sanitizer like Chlorine.

Do I have to put chemicals in my hot tub?
If you do not want to put any chemicals in to your hot tub, no problem, but you must drain and refill after each use and ensure that the water is never in the spa for more than 12 hours (keeping in mind it could take up to 10 hours just to heat it)! If this seems like too much work and you want to keep the same water in your spa then you have to balance Alkalinity, pH and Sanitizer or your water will become foul and dangerous.

What do I have to do to the filters?
Filters will over time clog eventually making it impossible for water to flow through. When this happens jets can feel less powerful and heaters may cut out. On a regular basis it is important to thoroughly clean your filters. To do this, remove the filter or filters from the spa and let soak for 24 hours in a bucket full of filter cleaner purchased from your local spa dealer. Another way to keep your filters clean is to remove them and spray them off a couple times a month.

  1. If my hot tub is empty and not set up, and I just want to use it for one night, can I just fill it up with water and turn it on. How would I do this? I’m planning on emptying it out the next day.

    1. You sure can! If you give us a call and let you know which hot tub you have, we can tell you how!
