We love inflatable hot tubs for their convenience whenever we need a relaxing session in hot water.

However, the joy of a hot tub is the clean water. Keeping the water in your hot tub clean is highly reliant on how clean you also keep the tub itself.

We all love our holidays, but with the pandemic, the leverage of traveling has been taken from us. We have had to revert to turning our backyards and gardens into holiday havens using hot tubs or paddling pools.

More and more people continue to buy hot tubs for massage and spa experiences that they can’t get elsewhere. 

Luckily, easy cleaning and maintenance. Like all the other areas in your home, hot tubs also need some TLC through periodic cleaning.

You can only unwind, relax, and let the warm water melt tension and stress away if you maintain clean water in the tub.

Tips On Keeping The Water In The Tub Clean

1. Utilize The Water Filtration System

Most inflatable hot tubs come with built-in water filtration systems. Hard water has mineral particles that cause clogging in infiltration systems sooner or later.

To ensure good water flow in your tub, we recommend cleaning the filter cartridges regularly.

For thorough cleaning, spray water on the filter cartridges using a garden hose. The force of a hose helps remove any debris caught on the filter pleats.

To keep the filter in good condition, use filter cleaners.

We recommend replacing the filter cartridges every six months to three years, depending on the quality of your water supply.

Regular replacement will help ensure the filtration system works smoothly. Always have spare filters in the house to swap when one set is being cleaned.

2. Use Chemicals

Bacteria and algae grow in water bodies, and a hot tub with water is no exception. Hence, sanitation is very crucial for maintaining clean water in your tub because it kills impurities that could be harmful to your skin and health.

One of the most common sanitizers for hot tubs and spas is bromine. For every liter of water, 3-6 milligrams of bromine can keep the water sanitized.

Bromine is available in tablets, which make it easily soluble in water. However, some people dislike the strong smell of bromine.

If the smell of bromine bothers you, chlorine is a good choice too. Chlorine is available in granular form, which also makes it dissolve in water quickly.

For every liter of water, 3-5 milligrams of chlorine will effectively sanitize the water.

You can also add shock oxidizers in your hot tub for sanitation. Oxidizers help destroy residue that comes from soakers like oils, cosmetics, and dead skin.

It also eliminates foul odors in the water and keeps the water free from clouding and organic matter. Use oxidizers weekly, but for no more than 10 minutes to effectively fight bacteria in the water.

3. Manually Clean The Hot Tub

To effectively remove calcification, scum buildup, and other residues in your hot tub, good scrubbing is needed. To get rid of dirt in your hot tub, scrub it with mild non-abrasive and suds-free cleaners, rag scrubbers, and soft nylon.

People living in areas with hard water need to clean their tubs harder due to the calcification that occurs in the tub internally and externally. Whenever you empty the hot tub, you should give it a good clean before replacing the water.

A cloth or sponge and warm water will help remove less stubborn stains. Thoroughly clean the tub, including the lid, and then rinse it down with cold water before you drain the water.

4. Replace The Water Before It Gets Filmy

Once the tub is clean, you need to refill it with clean water. Knowing when to do this is very important in keeping the water clean.

Leaving water in an inflatable hot tub for too long gives it a dirty look.

A buildup film may appear on the surface of the water and can have a foul odor.

You should change the water monthly, depending on how many people regularly use the tub.

5. Check The Water’s pH Level

Some hot tubs feature a water testing kit; if yours doesn’t, you need to buy one. Using a water testing kit, you can check the pH level of your water.

Your inflatable hot tub manual should specify the pH level the water should have; most range between 7.2–7.8 pH.

If the test falls below 7.2, the water in the tub is too acidic and could corrode your pumps if not changed. If above 7.8, the water could have mineral deposits.

We recommend buying safe granules to add to the hot tub to lower or boost the alkaline level.

6. Shower And Use The Bathroom Before Getting Into The Hot Tub

Before you get into a hot tub, everyone should shower first.

This will help remove any traces of perfumes, body oils, aftershave, and deodorants that tend to leave stains on the tub’s surface.

We also recommend using the bathroom before getting into the tub, especially if you have children.

Unlike adults, children aren’t too careful where they relieve themselves, and the last thing you need is for that to happen when you are enjoying a relaxing hot tub with them.

7. Keep The Lid On

Inflatable hot tubs come with a cover or lid for a reason – to prevent the entry of debris like dust, leaves, or dust that will contaminate your water. Whenever no one is using the tub, make sure to keep the water clean by covering it.


The sole purpose of investing in an inflatable hot tub is for gratification and relaxation.

Proper cleaning and maintenance are crucial to keep enjoying your spa, and these tips will help you keep your water clean.

After every cleaning session, if you need to store the hot tub away, make sure it dries thoroughly to prevent mold and mildew from growing on the tub while in storage.

For proper storage, remove all valves, lay the tub flat, fold it carefully, and check for any damp spots before placing it on a high shelf or in a sturdy bag.
