The necessity of automatic faucets in modern buildings
Today's buildings place a high priority on hygiene, especially post-pandemic. Many users are looking for ways to reduce contact with shared surfaces in restrooms and handwashing areas, making automatic faucets the ideal solution for convenience, safety, and corporate image.
Reasons why more organizations are turning to automatic faucets include:
Reduce the risk of germs on surfaces
Help manage water bills efficiently
Extend the life of the water system
Make the workspace look modern and professional.
This provides clear benefits in high-traffic locations such as:
Hospitals and Clinics: Reduce the risk of disease transmission between medical personnel and patients.
Industrial plants: especially food and pharmaceutical plants that require high cleanliness standards.
Offices and Public Areas: Ensure the safety of employees and visitors.
Research studies have found that bathroom fixtures harbor a high level of bacteria. Every time you use a public restroom and touch the sink faucet to turn on the water, germs are piling up. Automatic faucets with sensors can help reduce this problem.

How do automatic faucets work?
Automatic faucets use “object sensors” such as the user’s hand. The system will turn on the water as soon as it detects an object and turn it off immediately when there is no object within range, eliminating the possibility of forgetting to turn off the water or leaving it running unnecessarily.
Infrared sensor system
It is the most popular system because it works quickly, uses low energy, and is durable for heavy use.
Intelligent water control system
The new faucets have a system that calculates the appropriate amount of water each time, which helps to save water to another level. Based on average data, water usage can be reduced by up to 30–60%.
Types of automatic faucets commonly used today
Automatic faucet with direct electric power (AC Power):
Suitable for buildings that require high stability, such as factories or department stores.
Battery operated (DC Power):
Easy to install, no wiring required, can be used for 1-2 years per battery set.
Suitable for homes, schools, and general office buildings.
Hybrid (AC + DC):
There is main electricity at home, but there is a backup battery for continuity.
Suitable for buildings that must be open all the time
Self-generating system type:
Safe and environmentally friendly (no batteries or direct power required)
Suitable for buildings that want to reduce maintenance burden and prioritize sustainability.
Key benefits that organizations will receive immediately
✔ Clearly save on water costs
Reduce forgetting to turn off the tap and control water usage to only the amount needed.
In addition to preventing forgetting to turn off the faucet, sensor technology also helps precisely control the amount of water used each time. Tests have shown that automatic faucets can reduce water usage by up to 70% compared to conventional rotating faucets, enabling organizations to efficiently manage their water bills in the long run.
“For more detailed water-saving evidence and statistics on automatic faucets, along with data from the Portland Water Bureau and the EPA , check out this article.
✔ Increased hygiene safety
Reduce contact with faucets, reducing the risk of contamination in public areas.
✔ Reduce maintenance work
Conventional rotary taps wear out quickly, but automatic taps have no rotating or pressing parts.
✔ Enhance the image of the building
The handwashing area looks more modern, clean and organized.
"Create a modern and professional image"
"These devices demonstrate a commitment to user quality of life and environmental responsibility. Investing in automatic toilets makes a great first impression and elevates your space to international standards."
Common Problems (and Expert Solutions)
The sensor does not pick up the hand or picks up the wrong distance.
Caused by reflection or too much light
Edit: Change the position or use a version with noise reduction.
Water pressure is not constant
Old buildings often face this problem.
Solution: Install a water pressure regulator or choose a faucet that supports a wide pressure range.
The material is rusting or leaking.
Caused by low quality taps
Edit: Use 304 or 316L stainless steel or chrome plated brass (popular and inexpensive).
Easy installation in 3 steps
Remove the old faucet
Control box + mounting bracket
Install automatic faucet + connect water line
🔧 Installation takes less than 30 minutes !
How to choose the right automatic faucet for your job
1. Sensor sensitivity
Response time within 0.2–0.5 seconds should be the minimum standard.
2. Industrial grade materials
Choose 304/316L stainless steel or chrome plated brass (popular and inexpensive) to withstand heavy-duty use.
3. Brands with after-sales service
You should choose a brand that has spare parts readily available, a team of technicians to support you, and an on-site warranty.
"Key factors: After-sales service and spare parts stock"
"Automatic faucets are electrical devices that require maintenance and replacement parts as they age. Therefore, buyers should consider companies that stock spare parts, eliminating the need for overseas shipping. They also have after-sales service teams ready to provide consultation or visit the site to resolve issues quickly, ensuring peace of mind over long-term use."
4. Have reliable references and projects.
It is advisable to verify the work referenced from actual projects in food and pharmaceutical factories, schools, hospitals , or government buildings to confirm that the distributor is reliable and the products meet high hygiene standards.
5. Flexibility in system customization
For complex projects, choose a vendor who can customize the system to fit the existing structure (e.g. water pressure, piping, hot and cold water mixing system) and has technicians who can actually coordinate with the M&E team.

The price of a typical automatic faucet is
1,500–7,000 baht
The premium version is at
10,000–20,000 baht
Long-term expenses
Charcoal 100–200 baht/year
