Introduction

For hotel managers and vacation rental hosts, providing an outdoor hot tub is a guaranteed way to increase booking rates. However, guests often bring bath bombs hoping to enhance their soak.
In this  commercial guide, we'll discuss the six main reasons why bath bombs should never be allowed in your commercial outdoor hot tubs. You’ll learn about the operational risks, how it leads to negative guest reviews, and how to protect your expensive property investments.

 

What Are Bath Bombs?

Bath bombs are solid bath products made from a mix of ingredients, including citric acid, baking soda, and essential oils, which react when dissolved in water. This reaction produces the characteristic fizzing effect that bath bomb enthusiasts enjoy. While bath bombs are primarily used in regular bathtubs to create a fun and relaxing atmosphere, their ingredients can be problematic for the sensitive systems in hot tubs.

Bath bombs come in various formulations, often containing oils, salts, and fragrance ingredients aimed at moisturizing the skin, relieving stress, and promoting relaxation. However, these additives that make bath bombs so appealing in a bathtub can cause serious issues when used in hot tubs, which have more complex plumbing and filtration systems.

Why Bath Bombs Don’t Belong in Hot Tubs

Clogged Jets and Filters in High-Traffic Spas

When a bath bomb dissolves, it releases oils, glitter, and additives that quickly clog the commercial filtration systems of an outdoor hot tub. In a busy resort, these buildups reduce water flow and damage the high-performance LX pumps. This leads to unexpected "Out of Order" signs, costly emergency repairs, and ultimately, angry guests leaving bad reviews for your property.

Disrupting Water Chemistry

Hot tubs rely on a delicate balance of chemicals to ensure the water remains clean and safe. The ingredients in bath bombs can disrupt this balance. Oils, salts, and fragrances can alter the pH levels of the water, reduce the effectiveness of sanitizers like chlorine or bromine, and lead to cloudy water. This chemical imbalance can encourage bacteria and algae growth, making the water unsafe for use.

Maintaining a consistent chemical balance in your jacuzzi hot tub is crucial for safe and enjoyable soaking, so adding bath bombs should be avoided to prevent further complications.

Skin Irritation and Allergic Reactions

Bath bomb ingredients such as artificial fragrances, dyes, and essential oils can cause skin irritation or allergic reactions, especially when exposed to the heat of a jacuzzi. Hot water can amplify the effects of these substances, leading to rashes, itching, or more severe reactions in some individuals.

For those with sensitive skin or pre-existing conditions like eczema, the combination of hot water and bath bomb ingredients can exacerbate skin issues. Additionally, the hot tub’s chemical sanitizers might interact with the bath bomb ingredients, worsening irritation.

Stains and Residue on Surfaces

The dyes, oils, and glitter in bath bombs can leave stains on the surface of your jacuzzi or hot tub. Hot tubs often have soft surfaces like vinyl or acrylic that can easily absorb these colorants, leading to permanent discoloration. Oils may also leave a slippery residue on the tub, making it difficult to clean and even more prone to surface damage.

Over time, this residue can accumulate, resulting in unsightly marks and a slippery environment that can pose safety risks. These stains may be difficult to remove and may even require professional cleaning or repairs.

Excessive Foam and Bubbles

Another problem with using bath bombs in hot tubs is the excessive foam they produce. Bath bombs contain surfactants, which reduce the surface tension of the water and create bubbles. In a jacuzzi, where the jets are constantly circulating water, these bubbles can cause foam to overflow, clogging filters and disrupting the normal function of the hot tub.

Excessive foam can make the water appear unclean and lead to a buildup of residues in the system. This creates a maintenance headache, requiring extra cleaning and chemical treatments to remove foam buildup and restore proper water quality.

Damage to Hot Tub Components

Hot tubs engineered for commercial use rely on precision components like the US Balboa control system and titanium heaters. The corrosive salts and essential oils in bath bombs introduce foreign elements that disrupt these delicate systems. In extreme cases, the buildup can result in a complete breakdown, leading to expensive replacements that eat directly into your hospitality profit margins.

Safe Alternatives to Bath Bombs for Hot Tubs

Spa-Safe Alternatives: A Great Upsell for Hotels

Instead of letting guests use their own destructive bath bombs, hotels and Airbnb hosts can provide or sell Hot Tub-Safe Aromatherapy Products. These spa-safe liquid essences or crystals dissolve easily and won’t clog your commercial filters, offering a luxurious experience for guests while protecting your outdoor spa.

Natural Ingredients for Relaxing Soaks

Epsom salts, essential oils (used sparingly), and other natural alternatives can provide a relaxing soak in your jacuzzi without causing harm to the system. These ingredients are generally safer for hot tubs and can help soothe sore muscles, improve circulation, and promote relaxation.

However, it's important to consult with your hot tub supplier before introducing new products to ensure they’re compatible with your jacuzzi.

DIY Solutions: Herbal Sachets and Infusions

For a more natural approach, you can create your own hot tub-friendly aromatherapy experience with herbal sachets made from dried flowers or essential oils. These can be placed in the hot tub, releasing a calming fragrance without disrupting the water quality or damaging the system. Herbs like chamomile, lavender, and mint can create a soothing atmosphere and enhance the relaxation experience.

Tip: Always use a mesh bag or similar container for herbal sachets to prevent any debris from entering the water.

How to Maintain Your Hot Tub After Using Bath Bombs

Immediate Cleanup After Bath Bomb Use

If you’ve used a bath bomb in your jacuzzi by accident or out of curiosity, it’s crucial to clean the hot tub immediately afterward. This includes wiping down the surfaces, rinsing the filters, and running the jets to flush out any bath bomb residue. Cleaning your jacuzzi right away can prevent buildup and reduce the need for costly repairs.

Long-Term Care to Avoid Damage

Regular maintenance is key to preventing damage from bath bombs. Check and replace filters periodically, test the water chemistry frequently, and follow the manufacturer’s guidelines for cleaning and maintenance. By sticking to safe products and maintaining your hot tub, you can extend its lifespan and ensure a safe and enjoyable soaking experience.
