Trusted By Athletes In
Stillness, Deployed Anywhere.
We believe your sanctuary shouldn't be confined to a single room. The Still Plunge Inflatable Tub was born from a refusal to compromise. It delivers the rigid performance and thermal efficiency of a hard-shell tub with the freedom to take your practice anywhere—from your balcony to a weekend retreat. This isn't just an inflatable tub; it's a portable temple for your transformation.
Fortress-Like Durability.
Engineered to be unbreakable.
Forget everything you know about "inflatable". Our tub is constructed with military-grade, drop-stitch technology—the same used in high-pressure paddleboards and inflatable boats. Tens of thousands of polyester threads connect the inner and outer layers, creating a structure that is incredibly rigid and durable when inflated. It's puncture-proof, impact-resistant, and built to withstand years of rigorous use.
Engineered to Trap the Cold.
Maximum thermal efficiency.
An inflatable tub that can't stay cold is useless. Our multi-layer insulated design creates a powerful thermal barrier, significantly reducing heat transfer. This means your water gets colder faster and stays cold longer, forcing your chiller to work less and saving you energy. It's the performance of a hard-shell with the convenience of an inflatable.
A Vessel Built Different
Forget flimsy barrels and inefficient inflatables. Discover the difference true engineering makes.
Supportive Comfort, Surprisingly Soft.
Relax into your recovery.
When inflated, our tub is as firm and supportive as a traditional acrylic tub. But its surface has a gentle give that cradles your body, eliminating pressure points. This unique combination of firm support and comfortable contact allows you to relax completely, making it easier to breathe deep and maximize the benefits of your plunge.
The Complete Stillness System
The ultimate recovery sanctuary.
Combine the core elements of our ecosystem for a seamlessly integrated, plug-and-play experience. This is the most complete and profound stillness system we offer.

Frequently Asked Questions
Construction & Durability
How durable is an inflatable tub, really? I'm worried about leaks.
This is a valid concern, and we engineered this tub to shatter expectations. It is constructed with military-grade, drop-stitch technology, the same used in high-pressure inflatable paddleboards and boats. Tens of thousands of polyester threads connect the inner and outer layers, creating a structure that is incredibly rigid and durable when inflated to its 8 PSI rating. The material is puncture- and impact-resistant, designed to withstand years of rigorous use. We back this with a 2-Year Puncture-Proof Warranty for your peace of mind.
What are the exact dimensions, weight, and capacity?
Certainly. Here are the detailed specifications:
- Inflated Dimensions (LxWxH): 59" x 31.5" x 24" (150cm x 80cm x 61cm), comfortably fitting individuals up to 6' 9".
- Packed Dimensions: It packs down to a compact 28" x 16" x 15" (71cm x 40cm x 38cm).
- Weight (Empty): A highly portable 35 lbs (15.9 kg).
- Water Capacity: It holds up to 90 Gallons (340 Liters) of water.
Performance & Comfort
How well does it keep the water cold? Is it insulated?
Insulation is a key feature that sets our tub apart. It features a multi-layer insulated design with walls that are up to twice as thick as many competitors. This powerful thermal barrier significantly reduces heat transfer, meaning your water gets colder faster and stays cold longer. This forces your chiller to work less, saving energy and ensuring your plunge is always at the perfect temperature. The included Insulated Thermo-Lid also plays a crucial role by locking in the cold from the top.
Is it comfortable to sit in for several minutes?
Yes, we designed it for both support and comfort. When inflated, the tub's structure is as firm and supportive as a traditional acrylic tub. However, the surface itself has a gentle give that cradles your body and eliminates pressure points. This unique combination allows you to relax completely, making it easier to control your breathing and maximize the benefits of every plunge. The outer ring also provides a comfortable and stable edge for entry and exit.
Setup & Portability
What comes in the box? Is everything I need included?
Yes, it's a complete, ready-to-deploy kit. The box includes:
- The Still Plunge Inflatable Tub
- An Insulated Thermo-Lid to maintain temperature and keep debris out.
- A High-Speed Dual-Action Pump for rapid inflation.
- A durable, oversized All-Weather Travel & Storage Bag.
- A Puncture Repair Kit for total peace of mind.
How long does setup and packing away take?
The entire process is incredibly efficient. Using the included high-speed pump, you can go from unboxing to a fully inflated, rigid tub in just 5-10 minutes. Packing away is just as simple. After draining the water via the easy-drain tap, it deflates quickly and fits easily into its storage bag, with the whole process also taking about 10 minutes.
Maintenance & Warranty
Can I leave it outside in the winter?
The tub's material is UV-resistant and all-weather rated. However, if you live in a climate where temperatures drop below freezing 32°F, you should never leave the tub filled with water. The expansion of freezing water can put extreme stress on the seams and cause damage that is not covered by the warranty. In freezing conditions, we strongly recommend draining the tub completely after use.
What does the 2-Year Puncture-Proof Warranty actually cover?
Our 2-Year Warranty covers the full structural integrity of the tub under normal use. This includes any defects in the seams, the valve assembly, and the drop-stitch material that could lead to a leak or structural failure. It is a promise against manufacturing defects. The warranty does not cover punctures caused by sharp objects, damage from improper chemical use, improper storage (such as freeze damage), or normal cosmetic wear and tear.
What is the shipping cost and how long will it take to arrive?
We are pleased to offer FREE Shipping to the US and Canada on all orders. As our products are bulky shipments, this represents a significant savings of at least $200-$500 for you. Our total delivery timeframe is approximately 7-13 business days, which breaks down into 1-4 days for handling and dispatch from our stocked warehouse, followed by 6-9 business days for transit. Due to surged demand, handling may occasionally require an extra day, but our team is working at maximum capacity to get your order to you.
How is the chiller packaged to ensure it arrives safely?
We take extreme care in packaging your investment. To guarantee maximum protection during transit, every Still Plunge Chiller is shipped in a custom-built, reinforced wooden box. This robust packaging ensures your unit arrives in pristine, factory-perfect condition, ready for setup.
Can you explain the 100-Day Money-Back Guarantee?
Absolutely. We call it our 'Ironclad Promise.' From the day your chiller is delivered, you have a 100-day trial period to experience it in your own home. If you are not completely satisfied that it is the best cold plunge experience you've ever had, you can return it for a full refund. We do not charge restocking fees. Our 24/7 customer service team will guide you through the simple and hassle-free return process.

Great tub. Solid. Insulated. Only complaint is the drain plug. It’s a bit low, so getting that last bit of water out is tricky. But that’s a minor issue. Love it otherwise.
Rick A. (verified owner) –
Two-year warranty sold me. Had a small leak in the air valve after 6 months. Emailed support, they sent me a whole new valve assembly in 2 days. No questions asked. Amazing service.
Dr. Eva L. (verified owner) –
I’m 5’3″, and the 24″ height is perfect. It’s deep enough to get my shoulders under without feeling like I’m in a giant barrel. Very comfortable and supportive.
Pat C. (verified owner) –
Best part is the portability. I pack this in my RV. Setting it up takes 10 minutes flat. I can plunge at the campsite. My friends are all jealous. Durable as hell too.
Chloe M. (verified owner) –
I’ve owned two other inflatable tubs. They felt like kiddy pools. This one is different. The drop-stitch material is NO JOKE. It’s as firm as a real tub. The insulation is also legit. You can feel the difference.
Brian W. (verified owner) –
Love the tub, it’s fantastic. My only gripe is the carry bag. Once you unroll the tub, good luck getting it back in! The bag could be a little bigger. But the tub itself is 5-star quality.
Mark T. (verified owner) –
I’m 6’4″ and was worried I wouldn’t fit. No problem at all. Can sit upright and get the water over my shoulders. The material is surprisingly comfortable, not like a hard acrylic tub. Setup was maybe 10 mins with the pump. A+.
Jenna R. (verified owner) –
Fits PERFECTLY on my small apartment balcony. I was worried ‘inflatable’ meant ‘flimsy’ like a pool toy, but this thing is rock solid. Seriously, you can sit on the edge. Insulates way better than I expected too.
