Whether it’s the soothing hum of bubbling water, the gentle vibrations, or the dancing colours and light, bubble tubes are a fantastic way to support sensory integration. Here we answer your top questions on bubble tubes and explore how they help individuals living with sensory processing difficulties.

Firstly- what is a bubble tube?

A bubble tube is a tough acrylic cylinder filled with water and powered by air. As air moves through the water, it forms bubbles that reflect coloured lights in a hypnotising visual display.



Whether you’re looking to relax or engage the senses, the dynamic mix of colour, sound and movement make bubble tubes the perfect multisensory experience.

It’s an experience anyone can enjoy, adults and children alike. In particular, it may help those navigating a Sensory Processing Disorder or neurodivergent condition such as Autism or ADHD feel more engaged, focused, and in control. Let’s break it down further…


Bubble Tubes for Visual Stimulation

“Oh wow!” It’s a common phrase we hear when someone first sees a bubble tube. Not only does it grab the attention, but the colours and movement of the bubbles help:


Plus, it’s easy to add some playful fun with artificial fish or coloured balls, which can bob, weave, and float up and down.


Bubble Tubes for Tactile and Auditory Stimulation

With their gentle rhythmic vibration and sound, bubble tubes encourage touch and auditory awareness.

Especially for those who are visually impaired or living with hearing loss, holding the sides of a bubble tube to feel the soft vibrations can be a soothing experience that helps reduce anxiety and stress.

If a user is sensitive to new noises, we recommend being mindful of this when introducing them to a bubble tube. Noise-reduction headphones can be a good place to start, giving individuals the opportunity to interact with the bubble tube while controlling their auditory input. Likewise, it’s important to remember not all users will initiate or tolerate touch and may need to be slowly introduced to the vibrating sensation.

Bubble Tubes for Self-Regulation.

Self-regulation is the ability to understand and manage emotions and behaviour in response to various situations. It’s what helps us stay calm, cope with emotions like fear or stress, and react appropriately to what’s going on around us.

By providing predictable sensory input, the rhythmic nature of a bubble tube is ideal for supporting self-regulation. Whether used to relax or improve focus and attention, a bubble tube helps:


Think of bubbles like a visual lullaby – a soothing display to calm the mind and engage the senses.

Bubble Tubes for Inclusive and Accessible Sensory

One of the best things about Bubble tubes is how versatile they are. They can be adapted to all ages, all abilities, and various settings.

If the main purpose is to relax and unwind, a bubble tube can be left to gently cycle through a range of colours on its own. Alternatively, our Wireless Colour Controller puts you in control- encouraging interaction and skills such as colour recognition, sequencing and cause and effect. With its large, user-friendly buttons a controller is also great for those with fine/ gross motor skill difficulties.  

Let’s take a closer look at the different ways you can use bubbles across the Sensotec range…


On Their Own…

Bring your space to life with a stand-alone bubble tube, available in 1.2m high or 1.8m high. And there’s no need to worry about safety – an included wall bracket ensures the bubble tube remains completely stable and secure.

In a Module…

With our range of modules, you get a comfortable seat and sensory experience in one! Mirrors further enhance the experience by creating the illusion of multiple bubble tubes – a mesmerising display to delight the senses.  

Plus, you can customise the module colours for a personal touch and add or remove components to suit your space. View our Module and Bubble Tube range here.

On the Wall…

Maybe you’ve heard of a bubble wall? A Bubble Wall Panel gives the same effect as a bubble tube, but it has a flat front and is typically mounted to the wall like a screen.

If you have limited floor space, a bubble wall is a great streamlined option. Plus, you get added features like sounds, music, and control over the bubble direction. Learn more about our Interactive Bubble Wall Panel.

On the Move…

With mobile sensory equipment, bubble sensory therapy is accessible to anyone.

If you’re tight on space, users have limited mobility, or you want to move it from room to room, a mobile sensory unit means no one misses out. With Sensotec’s Mobile Roma Unit, you also get the choice of a bubble wall panel or bubble tube. Check out the Roma Sensory unit here or learn more about the benefits of portable sensory equipment.



Our Bubble Tubes are made from a thick, non-toxic acrylic, and come with a bracket or fixings to prevent tipping and keep everything safely secured. We also recommend adult supervision during use.  



A bubble tube should be emptied and refilled with fresh, clean water about every six weeks. However, using distilled water instead of tap water can extend this timeframe up to three months – this also applies to maintaining a bubble wall panel.

Wondering why it’s important to change the water in a bubble tube? If left for a long period, bacteria in the tube will gradually multiply. This can lead to complications with the diffuser and pump, and impact how well the bubbles form and move around the tube. In the worst-case scenario, the tube may overheat or leak and need to be replaced.

The good news is bubble tube maintenance is easy to do, and we provide detailed instructions to help you every step of the way. A couple of extra tips when it comes to looking after your bubble tube:

  1. If any water runs into the base during emptying or refilling the tube, the electronics may get permanently damaged. To prevent this, wrap a towel around the base before changing the water.
  2. We recommend adding BCB (Bubble Column Additive) in a fluid or tablet form to the water every month. This helps slow bacteria growth and keep the water clean.
  3. To avoid scratching and clouding the acrylic, do not use abrasive cleaners or solvents on the surface of the tube.
  4. Keep a record of each time the bubble tube is cleaned. We also recommend adding a 6-12 weekly reminder to your calendar.


Regular maintenance will guarantee you years of bubble fun and hassle-free use. And remember any issues, we’re only a phone call away!

So, you’ve done your research, and you think a bubble tube or bubble wall sounds great. But how do you know if it’s the right choice for your space?

The most important thing is to understand the sensory needs of the user. Will a bubble tube support their sensory integration? Further questions to ask yourself include:


We find bubble tubes are often the main attraction of a sensory room- they’re a multisensory experience for everyone to enjoy.
