10 Essential Hot Tub Rules for a Soaking Good Time

Hot tubs are supposed to be relaxing—but only when people feel safe. Whether you’re soaking solo, with kids, or hosting guests, these rules make sure everyone can enjoy the experience without turning fun into risk.

Hot Tub Safety Rules and Guidelines

When I first got a hot tub, I didn’t realize it came with a list of responsibilities. I just wanted to relax. But after learning about the real risks and hearing stories from other hot tub owners, I knew I had to follow some serious safety steps—and help others do the same.

Why Hot Tub Rules Matter

Hot tubs may seem harmless, but improper use can lead to danger. They carry some of the same risks as swimming pools, such as drowning or slipping, and also unique ones like overheating and infection. The CDC even lists illnesses linked to poor hot tub use. Florida law highlights drowning as a top cause of death in young children and requires safety features on all new spas.

It’s not just about legal rules–it’s about keeping people safe. Following hot tub rules can prevent accidents, infections, and allow everyone to enjoy their time without worry.

General Hot Tub Safety Guidelines

Water Temperature: Keep it below 104°F (40°C). Overheating can cause nausea, dizziness, or worse—hyperthermia. Stick to 15–20 minute sessions, and leave immediately if you feel lightheaded.

Shower & Clean Swimwear: Always shower first. Lotions, makeup, and even laundry detergent on clothing can mess with the water balance. Only wear clean swimwear—no street clothes.

No Glass or Electronics: One broken glass near the tub can cause serious injury. And electronics? Water and electricity do not mix.

Cover Use: Always keep the hot tub covered when not in use. It keeps heat in and curious kids or animals out.

Avoid Alcohol/Drugs: Alcohol and sedating meds slow your reflexes. In a hot tub, that can mean drowning or passing out.

Health Check: If you feel weak or too hot, get out. Pregnant women, older adults, or people on medication should talk to a doctor first.

Respect Occupancy Limits: Cramming too many people in isn’t just uncomfortable—it strains the system and reduces safety.

No Rough Play: No diving, dunking, or roughhousing. Hot tubs are shallow and slippery.

Hair Safety: Long hair should be tied up. Getting hair caught in jets or drains can be dangerous.

Hot Tub Rules for Children and Families

Age Restrictions: Children under 5 should never be in a hot tub. Older kids can only go in with close adult supervision.

Constant Supervision: Always stay within arm’s reach of young kids. Drowning can happen fast, even in shallow water.

Lower Temp & Time for Kids: For kids, set the water under 100°F and keep it short—no more than 10 minutes.

Barriers and Covers: Florida law requires safety barriers on all new tubs. Fencing or locking covers are essential to keep toddlers out.

No Toys or Wading: A hot tub isn’t a kiddie pool. Don’t allow toys, jumping, or running around it.

Alarms and Locks: Use door alarms and hot tub covers with locks to prevent unsupervised use.

Hygiene for Kids: No diapers in the hot tub. Only potty-trained kids with leak-proof swim diapers. Make sure they’re clean before getting in.

Sick Kids Stay Out: Diarrhea or infections? They can spread fast in warm water. Skip the soak.

Hot Tub Use During Pregnancy

Talk to a Doctor: This should be step one.

Watch Temperature & Time: Don’t let your body go above 102.2°F. At 104°F water, that can happen in 10 minutes. Use cooler water (100–102°F) and short sessions.

Skip First Trimester: Overheating early in pregnancy can raise risks for birth defects.

Hydrate: Drink water before and after. The heat will dehydrate you.

Be Cautious: Sit upright. Don’t lie down or lift arms/legs above water—that shifts heat around the body.

After Baby Arrives: Breastfeeding moms can soak, but keep the baby away from the water and stay hydrated.

Adult Health Concerns

Heart Conditions: If you’ve had a recent heart attack, unstable angina, or serious hypertension, avoid hot tubs. Stable heart issues may be okay—check with your doctor.

Blood Pressure Changes: Hot water lowers pressure at first, but it can spike when you get out. Be careful, especially if you’re on meds.

Medications: Drugs that make you sleepy (like painkillers or antihistamines) make soaking risky.

Chronic Illnesses: Diabetes, epilepsy, infections, or open wounds? Better to stay out unless a doctor says otherwise.

Food & Water: Don’t eat a big meal before soaking. Drink water to stay hydrated.

Mobility Issues: Older adults should take their time getting in and out. A handrail can help.

Hot Tub Etiquette for Airbnb Hosts and Guests

Clear Rules in Listings: Hosts should write out rules like: max occupancy, no alcohol or glass, and supervision for kids. Quiet hours help too.

Post a Sign: Keep a printed rule list by the tub. Include basic rules like: Shower before use, no kids under 8 alone, no glass or alcohol.

Require Supervision: Include in your rental agreement that children must be watched at all times.

Maintenance Matters: Hosts should test the water regularly (pH between 7.0–7.8; chlorine 3+ ppm). Lock the cover when not in use.

Cleaning Expectations: Ask guests to shower first and rinse the tub after use. Charging extra for messes is common.

Respect Neighbors: Remind guests about quiet time. Hot tubs can echo, especially in tight neighborhoods.

Emergency Info: Provide instructions for emergencies: shutoff switch, first aid, and local contacts.

Regulations and Codes

CDC Guidelines: Keep water clean (chlorine 3+ ppm, bromine 4–8 ppm), pH in range (7.0–7.8), and no kids under 5 allowed.

State Laws: Florida law says all new hot tubs must have one safety feature (fence, cover, or door alarm). Other states follow similar rules—check yours.

Sign Requirements: Some states require “No Lifeguard” or age limit signs. Make sure you post what your area requires.

Stay Local: Mention your local compliance to build trust with guests. For example: “This hot tub follows California’s safety code with proper signage and fenced access.”

Pregnant? Here’s What to Know

Soaking might feel great when you’re expecting, but it’s not always safe—especially in early pregnancy.

• Check with your doctor first.
• Keep water below 102°F and limit time to 10 minutes or less.
• Avoid the first trimester when the baby is most at risk.
• Stay hydrated before and after the soak.
• If you feel dizzy or lightheaded, get out immediately.

Health Notes for Adults

• Heart Issues? If you’ve had a recent heart attack, unstable angina, or severe high blood pressure—hot tubs might not be safe for you.
• Blood Pressure Swings: Hot water lowers it, but standing up quickly can make it spike. If you’re on meds, take extra care.
• Other Medical Conditions: Diabetes, epilepsy, or infections (especially skin ones)? Talk to your doctor before using.
• Don’t Soak After a Big Meal. Let your food digest and drink water to stay hydrated.

If You’re an Airbnb Host or Guest

I’ve rented homes and hosted many times, and I’ve seen how things go sideways fast without clear expectations.

For Hosts:

• Post Clear Rules in the listing and next to the tub.
• Include rules about age limits, alcohol, glassware, quiet hours, and occupancy.
• Keep water chemistry in check—chlorine at 3+ ppm and pH between 7.0–7.8.
• Use a lockable cover and install a safety fence if needed.
• Have a maintenance schedule and log test results if you’re serious about safety.

For Guests:

• Respect the home and follow all posted rules.
• Rinse off before use and don’t bring in snacks, drinks, or electronics.
• Be considerate with noise, especially in shared spaces or quiet neighborhoods.

What the CDC and Local Laws Say

• CDC recommends disinfectant levels of at least 3 ppm chlorine or 4–8 ppm bromine.
• Many states (like Florida and California) require barriers, safety covers, alarms, and signs.
• Florida defines any child under 6 as a “young child” and requires strict protections for new spas or pools.

Always check with your local health department to see what’s required in your area. And if you’re renting, stick with CDC and MAHC guidelines to avoid problems.
