If you’re a hot tub owner or are considering purchasing one, it’s essential to know what supplies you’ll need to keep it in tip-top shape. Maintaining your hot tub ensures it will last longer and helps keep the water clean and safe for you and your guests. This article will examine the hot tub supplies you need to keep on hand.
Water Testing Kit
The water in your hot tub needs to be tested regularly to ensure safety. A water testing kit can help your customers keep track of the pH and sanitizer levels of the water. Maintaining a proper pH level (7.2 to 7.8) is important to ensure the water is neither too acidic nor too alkaline. Additionally, the sanitizer level should be maintained within a specific range to kill bacteria and other contaminants in the water.
The most common items you can find in a hot tub water testing kit:
- Test Strips – Test strips are a quick and easy way to test the chemical levels in your hot tub water. They typically come with color-coded strips that indicate the levels of chlorine or Bromine, pH, total alkalinity, and calcium hardness.
- Liquid Testing Kits – Liquid testing kits are an alternative to test strips and often provide more accurate results. They typically come with reagents and test tubes. Add a few drops of each reagent to the water sample to test for the different chemical levels.
- Digital Testers – Digital testers are the most advanced option for testing hot tub water. They use electronic sensors to measure the chemical levels in the water and display the results on a digital screen.
- User Manual – A user manual is included with most water testing kits. It provides instructions on properly using the kit and interpreting the test results.
Cleaning Supplies
Keeping your hot tub clean is key to maintaining clear water and preventing long-term damage. These supplies make routine cleaning simple and effective:
Soft-Bristled Brush – Helps scrub the shell and interior surfaces, especially in corners or along the waterline.
Sponge – Ideal for wiping down the hot tub’s exterior and removing grime or water spots.
Microfiber Towels – Absorbent and perfect for drying surfaces after cleaning to prevent streaks.
Hot Tub Vacuum – Cleans debris from the bottom and sides of your spa. Essential for preventing dirt buildup that can clog filters and cloud the water.
Scum Absorber – Removes oils, lotions, and residues that float on the surface, keeping water clear.
Skimmer Net – Quickly scoops out leaves, insects, and other debris before they sink to the bottom.
Filter Cleaning Wand or Cartridge Cleaning Tool – Connects to your garden hose and easily rinses between filter pleats for a deep clean.
Grit Guard or Filter Cleaning Bucket – Keeps dirt from re-depositing on filters during soaking.
All-Purpose Spa Cleaner – A gentle, non-abrasive cleaner safe for hot tub shells and acrylic surfaces. Avoid household cleaners that can disrupt pH or damage materials.
Vinyl or Cover Cleaner – Use a product designed for hot tub covers to remove dirt and protect against UV damage.
Spa Vacuum (Battery or Manual) – Optional but helpful for deep-cleaning hard-to-reach corners and steps.
💡 Tip: Store all your cleaning tools in a waterproof tote or deck box to keep them dry and organized between uses.
Chemicals for the Hot Tub
1. Chlorine or Bromine – Chlorine or Bromine are sanitizers. They are essential chemicals needed to maintain a hot tub. Sanitizers kill bacteria, viruses, and other harmful microorganisms in the water, which can cause skin irritation and illness if left unchecked.
The two most common sanitizers used in hot tubs are chlorine and Bromine. Chlorine is a strong and effective sanitizer, but it can cause skin irritation, especially for sensitive skin. Bromine is a milder alternative to chlorine and is often preferred for indoor hot tubs or those with high temperatures. It’s also less likely to cause skin irritation.
Sanitizers come in different forms, such as tablets, granules, and liquids. Tablets are the most common form and can be added to a floating dispenser or placed in a feeder attached to the hot tub’s circulation system. Granules and liquids are added directly to the water and dissolve quickly to sanitize the water.
Maintaining the proper sanitizer level is essential — too little can lead to bacterial growth, while too much can cause irritation and damage to components. Regular water testing and monitoring help ensure the sanitizer levels are balanced and safe.
2. pH Balancers – Maintaining proper pH levels in the water is crucial for the sanitizer’s effectiveness and the user’s comfort. pH balancers are used to raise or lower the pH level of the water.
3. Alkalinity Increasers or Decreases- Alkalinity affects the pH balance of the water, and it’s essential to maintain it at an appropriate level. Alkalinity increasers or decreases are used to adjust the alkalinity level in the water. This helps to stabilize the pH level and prevent rapid changes that can damage the hot tub and irritate your skin.
4. Shock Treatment- Shock treatment is a strong oxidizer that is used to break down and remove organic materials like sweat, oils, and cosmetics that can build up in the water. It also helps to prevent the growth of algae and other harmful bacteria.
5. Calcium Hardness Increaser- Calcium hardness refers to the amount of calcium in the water, and it’s important to maintain the appropriate level to prevent corrosion and damage to the hot tub. A calcium hardness increaser is used to raise the calcium level in the water.

6. Filter Cleaner- Filters play a vital role in keeping the water clean, and cleaning them regularly is essential. A filter cleaner can help remove any oils, debris, and other contaminants accumulated in the filter. In addition, a clean filter will help the hot tub operate efficiently and reduce the likelihood of clogs or breakdowns.
Chemicals for the Cover
A cover cleaner is used to clean and maintain the hot tub cover, which is exposed to the elements and can become dirty over time.
When it comes to hot tub cover cleaner, there are several types available on the market. The type of cover cleaner you need depends on the material of your hot tub cover.
Here are some common types of hot tub cover cleaners:
- Vinyl Cleaner – Vinyl cleaner is designed specifically for hot tub covers made from vinyl material. It removes dirt, stains, and grime from the surface of the cover without damaging the material. Vinyl cleaner typically comes in a spray bottle and can be easily applied and wiped off with a cloth.
- Fabric Cleaner – Fabric cleaner is used for hot tub covers made from fabric or canvas material. It’s formulated to remove dirt, stains, and mildew without damaging the material. Fabric cleaner is often available in a spray bottle and can be applied and wiped off with a soft cloth or sponge.
- All-Purpose Cleaner – An all-purpose cleaner can be used for hot tub covers made from various materials. It’s effective in removing dirt, grime, and stains from the surface of the cover. All-purpose cleaners are available in various forms, including sprays, liquids, and wipes.
Chemical Dispenser
A chemical dispenser makes it easy to add chemicals to your hot tub without measuring them out by hand. These dispensers come in various forms, including floating dispensers and inline dispensers.

They can also help prevent slips and falls, which are common accidents associated with hot tubs. It’s important to ensure that the handrails are securely attached to the hot tub and can support the weight of users. Additionally, it’s a good idea to regularly check the handrails for any signs of wear or damage and replace them if necessary.
9. Surge Protector or Spa Disconnect Box- Protects your hot tub’s control system from power surges and lightning strikes. Many spa electricians recommend adding one for long-term equipment safety.
10. LED Test Light or Circuit Tester- A small but handy device to quickly check if your GFCI or breaker is working properly — especially useful for outdoor setups.
11. Phone or Emergency Contact – It’s always a good idea to have a phone or emergency contact nearby in case of an emergency.
With this safety equipment and accessories on hand, you can help ensure that your hot tub experience is safe and enjoyable for everyone involved.
Water Enhancers & Comfort Products
While the essentials keep your hot tub clean and safe, a few optional upgrades can take your soaking experience from ordinary to luxurious. These products aren’t must-haves — but they make every dip feel like a spa-day at home.
🌸 Aromatherapy Crystals & Spa-Safe Scents- Transform your soak into a sensory escape with aromatherapy products made specifically for hot tubs. Spa-safe crystals, beads, or liquid scents dissolve quickly and won’t interfere with your water chemistry. From calming lavender to energizing eucalyptus, these soothing fragrances enhance both relaxation and mood.
💧 Water Softeners & Clarifiers- If you live in an area with hard water, adding a water softener or clarifier can make a noticeable difference. These treatments help prevent mineral buildup, keep your water crystal clear, and create a smoother feel on your skin.
🫧 Foam Reducers & Enzyme Clarifiers- Over time, body oils, lotions, and soaps can create foam or cloudy water. Foam reducers and enzyme clarifiers naturally dissolve these residues, helping your sanitizer work more effectively while keeping your spa looking pristine.
🪷 Headrests, Cushions & LED Lighting- Comfort counts! Spa-specific headrests, cushions, and LED light systems make your hot tub experience more enjoyable. Adjustable pillows support your neck and shoulders, while soft lighting sets the mood — whether it’s a peaceful solo soak or an evening with friends.
🧺 Towel Warmer or Dry Rack – Keep your towels warm, dry, and within reach. A heated towel rack adds a spa-like touch to your soak, while a simple drying rack keeps towels fresh and prevents moisture buildup around your hot tub area.
💫 In Short- To elevate your soak, spa-safe aromatherapy salts, LED lighting, and comfort accessories create a relaxing atmosphere while maintaining balanced water chemistry. A few thoughtful additions can transform your hot tub from a backyard feature into your favorite personal retreat.
Common Mistakes to Avoid
Even with the best intentions, some simple habits can make hot tub care harder than it needs to be. Knowing what not to do can save you time, money, and frustration — and help keep your spa looking and feeling brand new for years to come.
🚫1. Over-Shocking or Mixing Chemicals Incorrectly- Adding too many chemicals (or mixing them) can throw off your water balance and cause irritation. Always follow the directions on the label and allow time between adding different products. When in doubt, test the water before adding more.
🧼 2. Using Household Cleaners- Avoid using regular household cleaners inside your hot tub — they can alter water balance and damage acrylic surfaces. Always use spa-specific cleaners designed for hot tub materials and finishes.
🌀 3. Neglecting to Clean Filters- Dirty filters restrict water flow, strain your pump, and make sanitizers less effective. Rinse your filters every 1–2 weeks and deep-clean them monthly with a filter cleaner. Keeping an extra filter on hand makes maintenance simple — just swap and soak!
🌞 4. Leaving the Cover Off Too Long- Your cover protects your hot tub from debris, UV rays, and heat loss. Leaving it off for long periods in direct sunlight can cause warping, fading, or cracking. After using your spa, rinse and dry the cover, then secure it snugly back in place.
🚿 5. Skipping the Pre-Soak Rinse- Before soaking, a quick shower helps remove lotions, oils, deodorant, and makeup that can cloud the water or cause foaming. A few seconds under the shower can save you hours of balancing chemicals later.
