Aquanello Eterna Wall Mounted Faucet Matte Black Cold Water ET4003-10
The Aquanello Eterna wall-mounted cold-water fountain faucet in matte black (ET4003-10) is a compact and minimalist wall-mounted faucet designed for a toilet fountain or small sink. The faucet is connected directly to the wall, leaving the sink or fountain free of a faucet hole.
The visible metal parts are made of high-quality stainless steel and feature a special multi-layer surface treatment. The stainless steel first receives a strong chrome-plated base layer, followed by a matte black coating. This combination results in an exceptionally strong, durable, and highly scratch-resistant matte black finish.
The ET4003-10 is specifically designed as a cold-water faucet and connects to a single cold-water supply line.
Wall-mounted cold-water faucet
The Aquanello Eterna ET4003-10 is intended for plumbing applications where only cold water is required.
The faucet is suitable for, among other things:
- Toilet sinks
- Guest bathrooms
- Small sinks
- Minimalist wall-mounted installations
- Restrooms with cold-water-only connections
The faucet does not mix hot and cold water. The integrated control allows you to easily turn the cold water on, off, and adjust the flow.
Sleek wall-mounted design
The ET4003-10 is mounted directly against the wall. This eliminates the need for a faucet hole in the sink, washbasin, or countertop.
The water supply is located behind the wall, and the connection is neatly finished with a round rosette. This ensures that only the essential faucet components remain visible, creating a very clean and minimalist sink setup.
Spout length of approximately 100 mm
The wall-mounted fountain faucet has a spout length of approximately 100 mm. This directs the water stream from the wall toward the fountain or sink.
The curved spout has a diameter of approximately Ø24 mm and slopes downward at an angle of approximately 35°.
By carefully aligning the faucet’s position with the basin during installation, the water stream can be optimally directed into the basin.
Compact design, approximately 74 mm high
The total height of the faucet is approximately 74 mm. This keeps the faucet body exceptionally compact against the wall.
The combination of the short projection, rounded shapes, and integrated controls makes this faucet particularly suitable for smaller restrooms.
G1/2 wall connection
The ET4003-10 features a standard G1/2 wall connection. This allows the faucet to be connected to a standard cold-water system.
After installation, the technical connection is concealed behind the round cover plate.
Round cover plate, approximately Ø55 mm
The wall connection is finished with a round rosette measuring approximately Ø55 mm.
This rosette complements the round and cylindrical shapes of the Eterna series and ensures a clean transition between the faucet and the wall.
Stainless steel with a strong chrome-plated undercoat
The matte black version stands out due to the special composition of its surface finish. The stainless steel base material is first coated with a strong chrome undercoat.
This chrome layer forms a hard, even, and durable base for the black finish. This allows the matte black coating to adhere strongly to the surface, creating an exceptionally robust multi-layer surface structure.
Exceptionally strong matte black coating
A high-quality matte black coating is applied over the chrome-plated undercoat.
The combination of stainless steel, the strong chrome undercoat, and the black topcoat ensures exceptionally high scratch and wear resistance.
This makes the ET4003-10 ideally suited for daily use in a restroom or bathroom setting.
The finish has been intentionally kept matte, giving it a deep black appearance without strong glare.
Advantages of the multi-layer finish
- Stainless steel base material: strong and durable foundation
- Chrome-plated undercoat: a hard and even base for the black coating
- Very high scratch resistance: suitable for intensive daily use
- Very high wear resistance: robust surface structure
- Strong adhesion: the matte black coating adheres firmly to the prepared undercoat
- Matte finish: deep black color without excessive glare
To maintain the matte black finish, we recommend cleaning the faucet with a soft cloth and a mild detergent. Avoid abrasive sponges and harsh, highly acidic, or alkaline cleaning agents.
No faucet hole required in the sink
A key advantage of wall mounting is that the sink itself does not require a faucet hole.
This allows for the use of an exceptionally sleek sink top or a minimalist basin, with the faucet supplied entirely from the wall.
Minimalist Eterna design
The Aquanello Eterna series is characterized by rounded shapes, cylindrical components, and minimalist details. The ET4003-10 follows the same design style with a compact round escutcheon, curved spout, and subtle controls.
The deep matte black finish gives the faucet a modern and architectural character and pairs exceptionally well with materials such as:
- Travertine
- Marble
- Natural stone
- Concrete-look
- Wood and wood-look finishes
- Light Ceramic

Matte black wall-mounted faucet with a sturdy chrome base
The Aquanello Eterna ET4003-10 is a stylish choice for anyone looking to install a compact cold-water faucet flush against the wall.
The combination of the 100 mm spout, G1/2 wall connection, Ø55 mm cover rosette, stainless steel base material, durable chrome plating, and matte black coating results in a high-quality and robust wall-mounted faucet.
Thanks to its extremely high scratch and wear resistance and its deep matte finish, the ET4003-10 fits perfectly into a modern and minimalist restroom design in matte black.
- Exceptionally scratch-resistant – the black finish is highly resistant to scratches and heavy daily use.
- Highly wear-resistant finish—the combination of a chrome-plated base layer and a black top coat ensures a strong and durable surface finish.
- Long-lasting color finish – the black top coat is designed to retain its appearance over time.
- Suitable for heavy-duty use – the strong surface finish makes the material ideal for bathroom faucets, showers, and accessories.
- Limescale may become visible—dried water droplets and limescale stand out more quickly, especially on a black finish.
- Avoid harsh chemicals—cleaning products containing chlorine or those that are highly acidic or alkaline can damage the surface finish.
