Hot Tub FAQs

Most spas must be connected to 240V electrical service, but some offer the option of operating on either 120V or 240V. While connecting to 120V can be less involved, most customers prefer the benefits of the 240V spa, which include quicker heating time and better temperature maintenance during cold weather use. This is because the heater output is four times as great in a 240V spa versus a 120V spa. If you choose to connect your spa to 120V service, you must be certain that it is a dedicated circuit, not shared by any other appliance, and has amperage rating appropriate for the spa you select.

Today’s finest spas feature a circulation pump that continuously filters the water to keep it clean and clear. It also provides the necessary flow to allow the heater to constantly maintain your set temperature. Spas without circulation pumps must rely on the low speed of a larger horsepower pump turning on periodically to provide filtration and the flow required for heating. The circulation pump is the most efficient method to provide flow for filtration and heating.

Truly beneficial hydrotherapy is directly related to the placement of the jets and to some extent, being able to adjust each jet where it is needed. These are the standards by which physical therapy and athletic hydrotherapy systems are judged. A common point of consumer confusion occurs when manufacturers load up a spa with lots of inexpensive, non-adjustable, stationary jets. It doesn’t make any difference how many jets a spa has if they are not properly located and plumbed to provide the correct balance of water, air and horsepower.

Most manufacturers recommend draining and cleaning your spa no more than 3 or 4 times per year, depending on how frequently you use it and how well you maintain your water. In most cases this simple process will only take about an hour to accomplish.

A spa can be installed indoors or outdoors, although over 90%, including those in cold weather climates, are installed outdoors. The two main considerations for installing a spa indoors are: will it fit through the door, and is the structural strength of the flooring adequate. A typical 3-person spa weighs approximately 2,500 lbs/1,150 kg when filled.

No. All above-ground portable spas are filled with water using a garden hose.

You need to have a proper foundation and meet any electrical requirements. We’ll walk you through the process and connect you with an expert to install your hot tub. See what to expect in the video below.

Here are a few things you can do to ensure installation and setup goes smoothly:

Check your HOA, city, and county rules and obtain any permits necessary.
Decide on a foundation that supports your hot tub, ensures proper drainage, and looks good.
Choose the perfect location, and remember to leave room for maintenance and entertaining.
Keep our Pre-Installation Checklist handy for reference.

Thanks to advanced water management and filtration systems, hot tub maintenance is easier than ever—routine tasks take just a few minutes a week. When we surveyed current owners about basic hot tub maintenance, nearly all of them said it was easy! Here’s a quick summary of how to maintain a hot tub:

Water: Check the chemical levels weekly with test strips and adjust them by adding the appropriate products per your owner’s manual—no chemistry expertise necessary. Drain and refills are only needed every 3–4 months, based on use.

Filter: Rinse and clean filters with a garden hose or filter flosser once per month. Replace as needed.

Cover: Use a cover to help keep your water warm and clean. It will protect your hot tub from debris and weather elements.
