Essential Hot Tub Supplies For Spa Care

While hot tub maintenance itself is one of the most important aspects of your spa, none of it could be done without the use of proper hot tub supplies.

These six essential supplies are a vital part of keeping your water crystal clear and your system running smoothly.

Hot Tub Cover

No matter where you live, having a hot tub cover is non-negotiable.

Not only does a cover minimize debris from falling into your water, but it also significantly reduces the work your system needs to do and maximizes your spa’s energy efficiency.

When choosing your cover, work alongside your dealer to ensure you select one that fits your model perfectly.

You’ll want a cover that fits snugly around your spa, ensuring a tight seal to improve heat retention.

Furthermore, consider investing in some cover locks to improve the overall safety of your hot tub.

Water Test Kit

Your water chemistry is vital to both the clarity and safety of your water.

Before you can appropriately treat your water, you’ll need to test it to find out what chemicals you need to add, and how much is needed.

To do this, you’ll need a water test kit or pH test strips.

These kits provide readings on various chemical levels in your water, including your water’s pH, alkalinity, and sanitizer levels.

Water Treatment Products

After testing your water, you’ll know which chemicals you need to add and how much of each one is required.

There is a wide range of chemicals you can add to your hot tub, but not all of them may be needed to keep it balanced.

Some of the essential chemicals you’ll need include:

  • pH increaser
  • pH decreaser
  • Alkalinity increaser
  • Sanitizer (like chlorine or bromine)
  • Oxidizing shock

Additionally, depending on your local water quality, you may need to include a few other chemicals in your routine, such as a calcium hardness increaser or a water conditioner.

Cleaning Supplies

Taking care of your hot tub goes far beyond simply keeping your water properly balanced.

It’s also important to keep your circulation system, shell, cabinet, and cover clean as well.

Your shell and circulation system are in constant contact with water, and over time this can leave a slick film building up on the surfaces.

To keep these aspects of your hot tub clean, you’ll want to have the following items:

  • A spa vacuum
  • Shell cleaner
  • Line flush

The vacuum will allow you to quickly clean the underwater surface of your hot tub between deep cleans, while the shell cleaner and line flush will clear out any tough grime during your quarterly drain.

Furthermore, the outside elements of your hot tub will need to be cleaned as well.

Taking care of your cabinet is as simple as wiping it down with a damp cloth once a month to remove any dirt and debris that may have built up.

When it comes to keeping your cover clean, you’ll want to wipe it down once a month before applying a UV protectant spray to reduce any color fading or cracking from sun damage.

Filters and Filter Cleaner

Your filters play an important role in your water’s clarity by filtering out any debris that gets into your water during use.

Generally, your hot tub filters will need to be changed once every 12 months, but they may need to be replaced sooner if they sustain damage.

It’s always a good idea to have a few extra filters on hand in case you discover your filters are torn and need to be replaced.

Additionally, filter care is a vital part of your hot tub maintenance routine.

To keep your filters clean throughout the year, you’ll need a filter cleaner to help break down stubborn buildup and keep them working efficiently.

Hot Tub Sponges

The last of the essential hot tub supplies is a hot tub sponge, or tennis ball if you want a budget-friendly alternative!

These sponges are designed to float along the surface of your water, absorbing any oils that may have been pulled off your skin and into the water during your soak.

Hot Tub Supplies for Added Safety And Comfort

Apart from the necessary supplies to properly care for your spa, there are some that can be added to make your spa safer to use, and more comfortable to be in.

Consider which one of these six optional supplies would be beneficial to your spa!

Cover Lifter

A cover lifter helps support the weight of your cover, making it easier for you to open and close your spa.

Not only does this protect your back and arms when lifting your cover, but it also ensures your freshly relaxed muscles aren’t strained by struggling with your cover after your session.


If your hot tub is installed above ground, it’s likely you’ll need to add some steps to make getting into your spa easy and safe.

Depending on your hot tub, there may be steps specifically designed to match your cabinet, maintaining a flawless aesthetic.

Hand Rail

Another way to enhance the accessibility and safety of your spa is to add a handrail.

Handrails provide stability, reducing the risk of your or your guests slipping as you enter and exit your hot tub.

If you also need steps, try looking for one that includes a handrail!


While your hot tub will come with cozy pillows built-in, for added comfort and support, you can add some additional headrests to your spa.

Many of these are designed to offer premium support to your neck and back, cradling it to easily align your muscles with the jets as you lean back to relax!

Booster Seats

Whether you have kids or simply want to adjust how your body aligns with the jets, adding inflatable booster seats can be the perfect solution.

These seats are an easy, cost-effective way to ensure everyone you invite into your spa can enjoy the same luxury experience, no matter their size!

Drink Holder

Do you enjoy settling into the bubbling water with a cocktail at the end of a stressful day?

If your hot tub doesn’t have built-in cup holders, it can be a challenge to fully relax while you try to hold your drink above the water between sips.

Adding a snap-on drink holder to the edge of your hot tub makes it easy to set your drink aside and unwind, making every second in your water pure bliss!
