## Quick Answer：

An all-in-one automatic tap system with soap and water is an integrated, touch-free handwashing fixture. It combines soap dispensing, water delivery, and air-drying. The [all in one faucet](https://www.tetch.net/wp-content/uploads/wp-mfa-exports/taxonomy/product_cat/all-in-1-taps.md) has electronic sensing and control and is installed at the same wash station. This allows the user to soap, wash, rinse, and dry their hands without moving to a separate unit.

TETCH manufactures a commercial tap system of touchless water sensor taps, 2-in-1 water and dryer taps, and 3-in-1 combination unit. Our certified manufacturing plants deliver an exceptional 0.1% defect rate across CE, UL, GS, FCC, RoHS, IPX, and UKCA standards, and maintain SEDEX ethical-audit compliance for its factories.

An all-in-one automatic tap system is beneficial because it combines handwashing and drying at one touch-free station. This helps improve hygiene, reduce water and paper-towel waste, and simplify maintenance. The system also prevents users from carrying wet hands across the restroom, hence preventing accidents.

## What Counts as a True Soap, Water and Air Tap System?

![A commercial bathroom installed with an all-in-one faucet combination unit from TETCH.](https://www.tetch.net/wp-content/uploads/2026/09/image-3.png)

A true soap, water and air (SWA) commercial tap system is an integrated, touch-free handwashing unit. The whole system provides soap, water, and hand-drying air from one coordinated fixture or system.

The system has sensors or electronic controls that detect the user’s hands and control the sequence. It also stops automatically when the cycle ends or when the hands are removed from the sensors.

The core requirements of the all in one faucet unit includes soap, water, air, control sensors, and an integration unit.

The industry also uses “combined hand-washing system” for electronically actuated soap dispensers, faucets, hand air-dryers, and associated hot-water equipment. IAPMO IGC 127-2022 addresses such systems, including materials, performance testing, physical characteristics, and markings.

## Which Manufacturers Supply Integrated Tap Systems?

Integrated tap systems combine soap dispensing, touch-free water delivery, and hand-drying airflow at a single washroom fixture or console. This system is also known as an all-in-one hand-washing station and is typically coordinated by a shared or under-counter control unit.

## How Are the Soap, Water and Air Modules Configured?

The all-in-one automatic tap system includes soap, water, and air modules. These are configured into four coordinated functions: above-counter components; under-counter components; shared and separate sensors; and power, water, and soap connections.

The three components function around one basin and are controlled by touch-free sensors supported by hidden services. The exact locations vary between countertop, wall-mounted, and behind-mirror models, but the functional division is generally the same.

### Above-Counter Components

The above-counter components are the user-facing components installed above the countertop, basin, or finished wall.

Above-counter components include:

- Soap – Delivers a controlled dose of liquid or foam soap.
- Water – Provides touch-free water for washing and rinsing.
- Air – Directs drying air onto the hands.
- Common (Decorative cover, mounting plate, pictograms, trim, accessible faceplate) – Provides the visible and cleanable interface.

In some systems, the soap outlet, water outlet, and air outlet are separate openings arranged over the same basin. In others, they are incorporated into a single combination unit which houses the faucet body, wall panel, or behind-mirror assembly.

### Under-Counter Components

These under-counter components are normally concealed below the countertop, behind the wall, or inside a service cabinet.

The components include:

- Soap – Stores and meters the soap supply.
- Water – Controls water supply and temperature.
- Air – Generates and transports drying air.
- Common control board – Coordinates the three functions.
- Service such as isolation valves, access panels, mounting brackets, and cable supports – Allows safe maintenance and adjustment.

### Shared and Separate Sensors

There are two types of sensors: shared sensor arrangement and separate sensor arrangement.

A shared sensor or common control system uses one coordinated detection and logic system for multiple functions. This setup is useful when the manufacturer has designed a programmed wash-rinse-dry sequence. It can reduce visible sensor hardware, but common controller failure may disable several functions at the same time.

A shared sensor system:

- Detects users at the wash station.
- Sequences soap, water, and air operation.
- Applies common timeout and shutoff settings.
- Reduces simultaneous or unnecessary activation.
- Uses one controller with multiple outputs.

On the other hand, separate sensors are more common in modular commercial systems. They allow the user to activate each function independently. This is more flexible because the user can soap, rinse, and dry without a fixed cycle.

The components include:

- A soap sensor that activates the [automatic soap dispenser](https://www.tetch.net/wp-content/uploads/wp-mfa-exports/taxonomy/product_cat/automatic-soap-dispensers.md).
- A water sensor that activates the faucet solenoid valve with a water tap.
- An air sensor which activates the dryer blower.
- A cabinet or service sensor with optional access, status, or safety function.

### Power, Water and Soap Connections

Most units operate at 100-240V AC via a step-down transformer or battery packs for installation purposes where electrical wiring is unavailable. Water requirement consists of a standard 15mm compression connector along with an isolation valve for servicing purposes. Soap containers vary from 500ml cartridges to 1.5-liter containers based on the number of passengers that come through.

## What Countertop and Basin Conditions Must Be Confirmed?

![Modern commercial bathroom equipped with water tap system.](https://www.tetch.net/wp-content/uploads/2026/09/image-4.png)

Before deciding on an all-in-one faucet combination unit, confirm that the countertop and basin can physically support the unit. Make sure that there is adequate user clearance, control splash, drain, and can accommodate all concealed services.

1. Countertop conditions – check the mounting type, material and structural strength, available counter space, and underside clearance.
2. Basin conditions – confirm basin type compatibility, basin dimensions, spout and outlet geometry, drainage and overflow, and sand water-containment performance.
3. User and accessibility conditions – check the following conditions if they are comfortable with the end users. Confirm basin height, knee and leg clearance, accessibility, compatibility with wheelchair or assisted use, sensor zones, and air stream comfort.
4. Service and maintenance conditions – Before installation, confirm access to soap reservoir, isolation valves, electrical isolation, and service hatch. Make sure there is sufficient space to disconnect hoses, drain cleaning, and leak inspection.

## How Should Facility Teams Maintain the System?

Facility teams should follow a fixed maintenance schedule to avoid complaints.

1. Clean the sensor lens weekly with a soft cloth to prevent dust from blocking detection.
2. Refill the automatic soap dispenser reservoir on a set cycle based on daily foot traffic, not when it runs dry.
3. Descale the water valve every three to six months in hard-water regions to maintain consistent flow.
4. Check the air filter on drying-equipped units monthly, since blocked filters raise motor temperature and shorten service life.

## How Do You Select the Right Manufacturer and Specs for Automatic Taps?

Before purchasing, verify key service capabilities and performance metrics:

- Supplier Capabilities: Confirm lead times, spare parts availability, warranty support, and relevant certifications (CE, RoHS). Request reference projects from your sector and ask about OEM, private labeling, or custom finishes for multi-site rollouts.
- Core Specifications: Compare sensor range (4–15 cm), flow rate (1.5–4 L/min), and soap dosage (0.5–1.2 ml). For hand-drying units, look for air velocities of 15–25 m/s. Check standby power draw and target a cycle rating of 300,000–500,000 activations to ensure commercial-grade durability.

### What Information Should Be Included in the Project RFQ?

A complete RFQ should list the project type, unit count and target installation date for the commercial tap system.

Include countertop material, thickness and existing cutout dimensions if the project is a retrofit. State the local power supply voltage and whether battery-powered units are acceptable as a backup option. List required certifications for the destination country, along with any finish or branding preferences.

Note expected daily foot traffic per washroom so the manufacturer can recommend the correct soap and water tank sizing. Confirm whether spare parts ship separately from the main order.

## Frequently Asked Questions from Buyers

### 1.How long does a combination tap unit last before parts need replacing?

1. 

Most units run 300,000 to 500,000 activations before a sensor, valve or pump needs replacing. In a typical office washroom, that translates to roughly five to seven years of daily use.

### 2.Can an integrated unit replace fixtures in an existing washroom without new plumbing?

Often yes, if the existing water supply line and drain align with the new cutout. Power supply and cutout size still need confirmation before ordering, especially in older buildings.

### 3.Do soap and water ever mix accidentally in a combination faucet?

Rarely, when the unit uses separate sensors for each function. Shared single-sensor designs carry a slightly higher risk in busy washrooms with overlapping hand movements.

### 4.Is an Integrated System More Cost-Effective Than Separate Fixtures?

Yes. Higher upfront unit costs are offset by lower installation and maintenance expenses. One cutout, electrical run, and service visit replace three. Payback is fastest on new builds; retrofits require budgeting for countertop modifications.
