It was announced on August 12, 2024, opened for crowdfunding from August 14 to August 28, 2024, and went on formal sale on September 9, 2024.

The details below come from Chinese-language launch reporting by IT之家 and an English-language headline from Gizmochina. Xiaomi’s own performance and safety claims are presented as claims, not as independently tested results.

Four water modes
The S1 is built around four separately controlled outlets. Launch coverage describes each as operated by its own piano-key-style button. The modes are listed below as reported.

Each button diverter also includes a flow regulator, allowing you to adjust the water flow during your shower. Moreover, the three button-style diverters on the valve allow for multiple modes to be activated simultaneously.
- This 12-inch showerhead is built with reinforced thickness for enhanced durability and strength. It incorporates air pressurization technology, which can reduce water usage by up to 30% compared to standard showerheads.
- Thermostatic shower valve：Our valve is equipped with the renowned CA43 thermostatic cartridge, known for its exceptional heat resistance and anti-scaling properties. Crafted from high-quality thermoplastic polymer, this cartridge outperforms other thermostatic cartridges. Additionally, our valve features a safety lock that maintains the water temperature at 100°F, providing protection against scalding.
- 6 Inch High Pressure Shower Head: Engineered for excellence, our showerhead features a reinforced design for superior durability and long-lasting strength.

| Concealed lower outlet | A concealed outlet described as splash-resistant |
Other physical features reported for the product are a 371 mm storage shelf with a tempered-glass panel and the adjustable riser that carries the overhead head.

- Adjustment range from room temperature up to 49°C.
- A default setting of 38°C.
- One report says a child-lock control must be pressed before the temperature can be raised above the default range. Treat this as a reported safety feature, not an independently verified one.
Xiaomi’s position, as reported, is that the constant-temperature design keeps outflow stable. No independent test of temperature stability is reported.
Display, power and water protection
The unit includes an LED display that reports water temperature in real time, using water-flow sensing. Reports say the display is battery powered by four AA batteries and carries an IPX5 rating. The same reports state a claimed battery life of up to 270 days. That figure is a manufacturer claim. It is not a measured result, and the reports do not say under what usage pattern it was calculated.
Rank #3
- 【22-Inch Rain & Waterfall Shower Head】Features both rainfall and waterfall modes, which can be used individually or simultaneously. The oversized 22-inch shower head provides wide, full-body coverage for an immersive shower experience, while the concentrated waterfall stream targets the neck and shoulders, helping ease muscle soreness and fatigue.
- 【Thermostatic Valve】Keeps the water temperature stable at the preset 100°F (38°C) without the need for frequent adjustments. It helps prevent scalding and temperature fluctuations caused by sudden drops in water pressure, making the shower safer and easier to use for the elderly and children. For a higher temperature, simply press the safety button and turn the temperature control knob.
- 【Flexible Handheld Shower】Equipped with a 59-inch flexible stainless steel hose for extended reach, making it easy to rinse hard-to-reach areas, bathe children or pets, and clean the shower after use. The angle-adjustable handheld shower holderr lets you easily direct the spray where needed, while the handheld shower features a smooth rounded-edge design for a comfortable, ergonomic grip.
- 【Button Diverter】The upgraded water control system replaces the traditional square controller with a more intuitive and convenient push-button design, helping reduce accidental switching when your hands are wet or slippery. All three shower modes can be controlled independently or used simultaneously for greater flexibility and convenience.
- 【Premium Finish & Easy Cleaning】Features an electroplated finish with a protective topcoat to help reduce fingerprints, water spots, and everyday stains, keeping the shower system looking clean and refined. Soft silicone spray nozzles make limescale easy to remove—simply rub them with your fingers for quick and easy cleaning.
Materials and durability claims
Launch coverage describes an antibacterial body made of 59-brass. Xiaomi claims 99.9% antibacterial effectiveness and a valve opening-and-closing life of 1.2 million cycles. These are company claims as relayed by IT之家. The reports do not identify a laboratory, test method or standard behind them, so they should be read as marketing figures rather than verified specifications.
What is and is not established
- Established by the reports: the product name, the mainland China announcement and sale dates, the three prices above, the four outlets, the reported dimensions, the temperature range and default, and the display and power description.
- Attributed, not verified: the safety features, the antibacterial and durability figures, the 270-day battery life and the IPX5 rating.
- Not established: independent testing of any kind, a direct quote from a named Xiaomi spokesperson, current stock or pricing, availability outside mainland China, warranty terms, and installation or water-heater compatibility requirements.
Checks before specifying or buying
If you are considering the S1 for a project or a home refit, the launch reports do not answer the questions that matter most for installation. Before committing, you should:
Rank #4
- Push Button Diverter: Vanfoxle has developed an improved version of water control —— Replacing the traditional square-shaped controller to a push-button diverter. The new mechanism ensures users don’t accidentally switch to the wrong mode with slippy hands. Additionally, with the help of the new button design, users can enable three rainfall shower mode, wall mount shower mode and handheld shower spray simultaneously in their preferred shower scenario.
- Multi function Handheld Shower Head: Its unique 2-in-1 design stands out from others. The spray gun mode features a high-pressure hose to enable water to flow through a single streamline which is widely used to clean pets—and even the bathroom itself. This new feature allows for a whole new shower experience.
- Temperature balanced shower valve: The valve uses a high-performance constant temperature cartridge CA43 manufactured in France, which has obtained multiple international certifications. CA43 is mainly made of high-end thermoplastic polymer, effectively improving the heat resistance and anti-scaling properties of the cartridge. At the same time, the valve is equipped with a 100°F temperature lock, which can effectively prevent users from getting scalded while using the shower system.
- High Pressure Rainfall Shower：Utilizing cutting-edge air injection technology, this rainfall shower head blends water with air, doubling the pressure for a natural rain simulation. The reinforced panel, more than doubled in thickness, ensures durability under increased water pressure. Not only does it deliver outstanding longevity, but it also conserves water by up to 30%-50%, making it ideal for households with low water pressure seeking a high-pressure shower experience.
- 6 Inch Angled Showerhead: Engineered with a reinforced panel over twice as thick as standard models, this uniquely angled showerhead withstands high water pressure while offering long-lasting durability. Its downward tilt delivers a refreshing rainfall experience ideal for body rinsing—perfect for moments when you want a full shower without getting your hair wet.
- Confirm that the model is sold in your country and find the current price, which may differ from the 2024 figures above.
- Ask a licensed plumber to confirm compatibility with your water pressure, your water heater type and your riser mounting height.
- Obtain the IPX5 rating, battery specification and warranty terms in writing from the seller rather than relying on launch coverage.
- Check how the AA batteries are accessed for replacement, since the display depends on them.
- Check whether the temperature limit and child-lock behavior match the hot-water safety requirements that apply where you work or live.
Mainland China reports are a starting point for identifying the product, not a substitute for the seller’s own documentation.
