Hot tubs are a great way for families to relax, unwind, and enjoy time together. But for parents and carers, a common question comes up: can children safely use a hot tub - especially those under 5?
The short answer is yes, children can safely enjoy a hot tub with the right precautions in place. That includes toddlers and preschoolers, provided you control the water temperature, limit time in the tub, and supervise closely.
In this guide, we’ll explore how children of different ages can use hot tubs safely, what risks to be aware of, and what steps to take to ensure a safe and enjoyable experience for the whole family.
Is It Safe for Young Children to Use a Hot Tub?
Children’s bodies are more sensitive to heat than adults. They overheat more quickly and may not be able to tell when they’re becoming too warm or uncomfortable. That’s why many general safety guidelines recommend that children under 5 avoid hot tubs at typical operating temperatures (38–40°C).
However, that doesn’t mean young children can’t enjoy a hot tub at all. With the right adjustments - such as reducing the water temperature and keeping sessions very short - children under 5 can safely be introduced to the hot tub experience.
Safe Hot Tub Use by Age Group
Under 5 Years Old
Children under 5 can use a hot tub safely if strict precautions are followed:
- Lower the water temperature to 32–34°C (around the temperature of a warm bath)
- Limit sessions to 3–5 minutes
- Have them sit on a step or shallow seat so their upper body remains out of the water
- Always supervise closely
- Make the experience gentle and calm - more like a warm splash than a long soak
Ages 5–12
Older children can tolerate slightly warmer water (up to 35–37°C), but it’s still important to:
- Limit time to 5–10 minutes
- Encourage regular breaks
- Ensure they stay hydrated
- Maintain full adult supervision at all times
Teenagers
Teenagers can generally enjoy the hot tub much like adults, though it's still advised to:
- Keep sessions under 15 minutes
- Avoid very hot temperatures
- Continue monitoring hydration and wellbeing
Hot Tubs as Splash Pools in Warmer Weather
In the summer months, a hot tub can double as a brilliant splash pool for younger children. By turning down the temperature to a safe, cool setting (even as low as 28–30°C), the hot tub becomes a safe and manageable water play area.
This makes it ideal for:
- Water play without the risks of deep paddling pools
- Controlled environments where adults can easily supervise
- Keeping little ones cool and entertained on hot days
Just add a few water toys and sit back while they enjoy gentle splashing in a secure, relaxing space. It's a fun way to get more use out of your hot tub during warmer weather - even when you’re not in full “spa mode.”
General Safety Guidelines for Children in Hot Tubs
No matter your child’s age, there are some universal rules you should always follow:
- Never exceed 37°C when children are using the hot tub
- Always supervise closely - never leave a child unattended, even for a moment
- Discourage full-body immersion in young children
- Keep sessions short and sweet
- Provide drinking water before and after to prevent dehydration
- Avoid hot tub use when children are tired, unwell, or overly active
- Keep the water properly balanced and sanitised to avoid irritation or infections
When to Avoid Hot Tub Use
There are times when it’s best to skip the hot tub, including if your child:
- Has a fever or is feeling unwell
- Has an open cut, rash, or skin condition
- Has a medical condition that could be affected by heat (consult your GP)
- Has recently engaged in high-energy play and hasn’t cooled down yet
Final Thoughts
Children can enjoy hot tubs safely - even those under 5 - when proper care is taken. By lowering the water temperature, limiting time, and staying present at all times, families can safely include even the youngest members in hot tub fun.
That said, like with anything, parents and carers know their children best. If you have any doubts or your child has specific health considerations, it’s always a good idea to seek advice from a healthcare professional.
When used responsibly, a hot tub can be a wonderful space for bonding, relaxing, and making memories together as a family.
