Top Questions New Hot Tub Owners Ask (Answered!)

Buying a hot tub is an exciting investment, but if you're new to owning one, you probably have a few questions. Whether you’re wondering about maintenance, energy efficiency, or how to get the most out of your spa, we’ve got you covered. Here are some of the most common questions new hot tub owners ask—answered!

1. How Often Should I Change the Water in My Hot Tub?

You should change your hot tub water every 3 to 4 months, depending on usage and water quality. If you use your hot tub frequently or with multiple people, you might need to change it more often. Regular water changes keep your spa fresh and ensure a clean soaking experience.

2. What Chemicals Do I Need to Maintain My Hot Tub?

To keep your water clean and balanced, you'll need:
✅ Sanitisers (Chlorine or Bromine) – Keeps the water free from bacteria.
✅ pH Balancers – Helps maintain the right water chemistry.
✅ Shock Treatment – Oxidises contaminants and restores clarity.
✅ Alkalinity Adjusters – Prevents rapid pH swings.
✅ Calcium Hardness Increaser – Helps prevent corrosion and scaling.

Testing your water 2-3 times per week ensures everything stays balanced.

3. How Hot Should My Hot Tub Be?

Most people set their hot tubs between 100°F – 104°F (37°C – 40°C).
🔹 Cooler (98°F/37°C) for a relaxing soak.
🔹 Warmer (102°F-104°F/39°C-40°C) for muscle relief.

Tip: If children are using the tub, keep the water temperature at 98°F/37°C or lower and limit their soak time.

4. Can I Use My Hot Tub in Winter?

Absolutely! In fact, winter is one of the best times to enjoy a hot tub. To ensure a smooth experience:
❄️ Use a high-quality insulated cover to retain heat.
❄️ Keep the temperature at a consistent level to prevent freezing.
❄️ If you're not using your hot tub, consider winterising it (draining and storing it properly).

5. How Do I Keep My Hot Tub Water Crystal Clear?

✔️ Regular Water Testing – Adjust chemicals as needed.
✔️ Shower Before Use – Reduces oils, lotions, and dirt.
✔️ Filter Maintenance – Rinse weekly, deep clean monthly, and replace yearly.
✔️ Shock Your Water Weekly – Eliminates organic contaminants.

6. Can I Use Bath Bombs or Essential Oils in My Hot Tub?

No, regular bath bombs and oils can clog filters and create buildup in your spa. Instead, use hot tub-safe aromatherapy products designed for spa use.

7. How Many People Can Fit in a Hot Tub?

This depends on the model. Typical capacities are:
👤 2-3 person models – Great for couples or small spaces.
👥 4-6 person models – Ideal for families.
👨‍👩‍👧‍👦 7+ person models – Perfect for entertaining.

When choosing a hot tub, consider seating, comfort, and available space.

8. How Do I Drain and Refill My Hot Tub?

📌 Step 1: Turn off the power.
📌 Step 2: Attach a garden hose to the drain valve.
📌 Step 3: Open the valve and let water drain completely.
📌 Step 4: Wipe down the interior and refill with fresh water.
📌 Step 5: Turn the power back on and balance the chemicals.

Refilling with fresh water every 3-4 months prevents buildup and keeps your hot tub performing at its best.

Owning a hot tub is a fantastic way to relax and unwind, but proper care is essential to keep it in top condition. By following these tips, you'll enjoy crystal-clear water, lower maintenance costs, and a spa experience that lasts for years.
