Swimsuit or skinny dip: it is totally a personal preference and sometimes a question of logistics. If you use a swimsuit, there are a couple of things to consider. Adding clothing and swimsuits to your hot tub soaks can introduce detergents, contaminants, and additives to your hot tub water that can cause foam or frothing. But if you have a swimsuit that is solely for hot tub use, you may be able to avoid this issue. Instead of washing your swimsuit with detergent, simply rinse it clean after your spa soak. The same chemicals that sanitize your water will sanitize your swimwear, too. Simply hang to dry in the sun or lay flat outside. The sun can also act as a sanitizer. Then when you retreat to soak in your spa again, you won’t have to worry about detergents and oils clogging up your filters and equipment.

According to The American College of Obstetricians and Gynecologists (ACOG), hot tub use is not advised during pregnancy. Because the heat of the water can raise your body’s core temperature in the same way that a fever can, this allows a chance of risk to the baby. There is also a risk to the mother of overheating and dehydration.

For a safer option, lower the temperature of the hot tub and limit time to under 10 minutes. Also keep your head, arms and upper torso above the water. Get out if you become uncomfortable or overheated.

Most importantly, always consult your OBGYN or doctor if you plan to use your hot tub while pregnant. The recommendation may change depending on your health status.

The perfect spa is designed for the whole family to use. However, each individual child may have needs that are specific to their growth and development. Although hot tub use is not recommended for infants and very young children, older children will enjoy this special time with their families. IHT offers brands from Hot Spring®, Caldera®, Freeflow®, BestLife®, and Nordic Hot TubsTM to help you find the perfect fit for your whole family. Some cool-down seats offer higher seating to keep a child’s torso out of the water, allowing for a cooler soaking experience. You can also turn down the water temperature to extend your spa soak together. Consult your children’s pediatrician or family doctor to make sure a hot tub session is right for your littlest ones. As for pets, you’ve made a great investment in your IHT hot tub. Don’t risk damage from pet hair and dander that can clog filters and plumbing. You also don’t want claw scratches on your spa shell. Since pets can’t sweat like humans, the heat of the water can also be dangerous, overheating their bodies quickly. As an option, set up a kiddie pool next to your hot tub for your pet to play in so they can enjoy family time in close proximity while you soak.

There are many professional spa aromatherapy products on the market. IHT recommends you use only products specifically made for hot tub and hot water use. Other products for home use may clog your filters and damage your spa. IHT carries a wide range of hot tub approved products to choose from. Aromatherapy products designed for hot tubs will not void your hot tub warranty.

Just like you wouldn’t want to pour chemicals into your washing machine around the clock, there’s no need to add chemicals to your hot tub water all day long. Dispensers do exactly that – they dispense chemicals all day whether your hot tub water needs it or not.

Part of the issue with dispenser tablets is that they do not dissolve in an even pattern. Pieces can break off and sit on the surface of your hot tub below the dispenser. This is dangerous for your beautiful new spa, as sitting chemicals may etch and pitch your shell’s surface. Once the damage has been done, you’ll be left with a rough surface that cannot be repaired, causing hazards to skin and swimsuits. For other easy-to-use water care options, contact your local IHT water care specialist for recommendations that are safe to use in your spa.

Although the quick answer to most hot tub drains onto your lawn is ‘yes,’ there are a few things you want to do. First, you need to consider what type of water care chemicals are in your hot tub.

With a chlorine or bromine spa, it’s important to let your chemicals evaporate before you drain your spa water Use your test strips to ensure that your chlorine or bromine reading is at zero after leaving your hot tub cover off during the day. When the number is neutral, you can use your spa water on your grass and on non-edible flower and garden plants. This is a great way to recycle your water, especially if the season is dry.

If you use SilkBalance™, you don’t need to worry about draining. Feel free to drain your spa at any time. It will not damage grass or plants

Saltwater spas should never be drained onto your grass. The salt in your spa could be harmful to plants. You can drain it through a hose into an area free of vegetation. This can keep your lawn looking healthy and undamaged by the salt in your spa.

If you need additional draining instructions, contact IHT’s customer care department at 303-296-7727.

This is an excellent question. Different hot tubs have different seating configurations, including differences is width, depth, and jet placement. That’s why we offer you the opportunity to schedule a free test soak to experience our different hot tub options before you buy. Our professionals are experts at fitting you to the right seating that is perfect for your height and body type. And with a private test soak, you’ll be able to ask all your questions and try out the jets to make sure that you choose a hot tub that is ergonomically correct for your body.

Quality spas carry several different certifications that allow for safe hot tub use. Although many municipalities allow for a hot tub cover to secure your spa for safety, some do require an additional barrier or fence. If you have questions about fence, gate, or barrier requirements for your local Colorado municipality, contact IHT at (303) 296-7727 to obtain the information you need.

When searching for a new spa, the first thing to consider is what hot tub size and amenities fit your lifestyle.

Are you looking for an easy plug-and-play spa that plugs right into a standard dedicated outdoor outlet? These spas are easy to move, because they aren’t hardwired into your home. With a 110V unit, lower electrical use means energy-efficient options. For example, the heater will not come back on until the jets are turned off. If you use your hot tub for a quiet retreat for two, a 110V plug-and-play hot tub may be a good option. However, if you need the power of a larger spa with lots of features, a 230V option is a great idea. 110V spas are only offered by certain manufacturers, but there is a wide selection of options if this is your preference.

When thinking of about a 230V hot tub vs. a 110V spa, you can think in terms of power. Double the power means extra amenities that may make your hot tub ownership experience better than ever. From WiFi and Bluetooth® connectivity to extra seating and powerful jet action, a 230V spa delivers exceptional hydrotherapy and luxury options.
