Frequently Asked Questions

Is maintaining my spa water difficult?

Not at all. With intuitive water care systems and easy-to-follow routines, most of the work is minimal and takes just a few minutes each week. Features like automated cleaning cycles and guided care options help keep your water balanced and clear without constant attention.

Instead of complicated upkeep, you get a straightforward process that fits into your routine, so you can spend less time managing your water and more time enjoying it.

Is Sundance® spa water safe for kids and families?

Absolutely. Sundance® spa water is properly maintained, it's safe and enjoyable for the whole family. Advanced water care systems like MicroClean^® filtration and ClearRay^® Active Oxygen help keep the water clean, balanced, and gentle on skin and eyes, creating a comfortable environment for all ages.

As with any hot tub, children should always be supervised, and it’s best to use slightly lower temperatures and shorter sessions for younger users.

What is True Water® and how does it work?

True Water™ is our advanced water care system designed to keep your spa water clean, clear, and easy to maintain.

Instead of relying on a lot of traditional chemicals, TrueWater™ uses trillions of oxygen-filled nanobubbles to continuously help cleanse the water—reducing contaminants and keeping it fresh. The result is water that looks clearer, feels softer on your skin, and requires far less hands-on maintenance. In fact, you'll only spend about 15 minutes per month caring for your water.

What does properly maintained Sundance® spa water feel like?

Sundance® water feels as good as it looks — clean, clear, and incredibly inviting.

It’s soft and gentle on your skin, without the harsh dryness or strong chemical smell often associated with traditional spa water. You’ll notice the difference right away. The water feels smooth, refreshing, and comfortable, so you'll want to soak in it longer.

With balanced chemistry and advanced care systems working behind the scenes, every dip feels pure,effortless, and exactly how relaxation should feel.

How often should I drain my hot tub?

About every 3-4 months, depending on usage, water care routine, and number of users.

Regular maintenance and advanced systems like True Water™ can help keep your water cleaner longer, but periodic draining and refilling ensures the best overall experience. If you use your spa more frequently or have more bathers, you may need to refresh it a bit sooner.

A simple rule: when the water no longer feels as fresh or balanced as it should, it’s time for a change.
