Aquanello Eterna Thermostatic Shower Faucet Cartridge ET2300-00

The Aquanello Eterna in-wall assembly for the ET2300-00 thermostatic shower faucet forms the technical foundation for a comfortable and minimalist built-in shower. The entire technical assembly is mounted behind the wall, after which a matching Aquanello Eterna finish plate is installed on the outside.

The integrated thermostatic technology allows you to conveniently set the desired water temperature and helps maintain it as consistently as possible while showering. As a result, the ET2300-00 in-wall unit combines high shower comfort with a sleek and uncluttered wall appearance.

Thermostatic Concealed Unit for Comfortable Showering

The Aquanello Eterna ET2300-00 was developed as the technical core for a thermostatic in-wall shower faucet.

The thermostatic control adjusts the ratio of hot to cold water when the water supply changes. As a result, the set temperature remains as stable as possible during normal use and needs to be manually adjusted less often.

Technology Fully Concealed Behind the Wall

The in-wall unit is installed entirely within the wall. After the wall has been installed and finished, only the visible control elements of the matching trim piece remain visible.

This creates a sleek and minimalist shower environment without a large surface-mounted faucet body on the wall.

Sturdy built-in box

The technical components are housed in a robust built-in box. This protects the technical components during installation and makes it easier to position the system securely within the wall structure.

The integrated mounting points around the housing allow for secure fastening before the wall is further finished.

Adjustable installation depth

According to the technical specifications, the system is suitable for an installation depth of approximately 68 to 90 mm. This allows for some flexibility in placement relative to the final finished wall.

Correct positioning during the structural work phase is important so that the matching finishing panel can later be neatly mounted against the wall.

Compact technical dimensions

According to the technical drawing, the in-wall unit has overall dimensions of approximately 127 x 131 mm. This keeps the technical installation relatively compact and allows it to be fully integrated into the wall construction.

The round central installation zone has a diameter of approximately Ø115 mm.

Can be combined with a Eterna trim piece

The ET2300-00 serves exclusively as the technical flush-mount unit. To complete the faucet, a matching Aquanello Eterna thermostatic trim is mounted on the exterior.

This allows the technology behind the wall to be combined with a visible finish that matches the chosen bathroom style and the other products in the Eterna series.

Please note: The exposed trim is not included and must be ordered separately, unless the ET2300-00 in-wall unit is part of a complete Aquanello Eterna shower set.

Technical foundation for a minimalist thermostatic built-in shower

The Aquanello Eterna ET2300-00 forms the technical foundation for a high-quality thermostatic in-wall shower faucet. Because the entire internal mechanism is installed behind the wall, the shower area remains sleek and uncluttered.

The combination of thermostatic temperature control, a sturdy in-wall housing, and an adjustable installation depth of approximately 68 to 90 mm makes the system suitable for a professional and durable in-wall installation.

When paired with a matching Aquanello Eterna trim set, the result is a complete thermostatic shower faucet that combines comfort, technology, and minimalist design.

The majority of our orders are shipped with various carriers. Sometimes we use other carriers to deliver specific orders or to ease the load on the main carriers to meet our delivery promises.

The expected delivery time is always shown on the product page. Most products that we have in stock are shipped the same day. The evening before delivery, you will receive tracking information with a time window for the delivery. Important to know: the drivers of our chosen carriers deliver the products to the front door on the ground floor.

Also, for larger products such as granite sinks, large fragile sinks, cabinets, etc., you will receive a tracking code in the evening. These products are not delivered to the neighbors and a signature is required, so someone must be home to receive the product. Note: these large products are not delivered on Saturdays!

If the delivery of a large product fails on the first attempt, the carrier will contact you via email or SMS to send you a schedule so you can choose a time when you will be home.

Delivery surcharges of €30 to €100 apply for shipments to islands, due to additional logistical costs such as water transport and limited accessibility, and there are surcharges for pallet shipments for transporting fragile and heavier products.

Aquanello Eterna – Luxury Stainless Steel Bathroom Faucets and Shower Sets

Discover the Aquanello Eterna collection: an extensive range of high-quality stainless steel bathroom faucets, thermostatic shower faucets, rain showers, and stylish faucets for the bathroom and toilet. With its refined European design, minimalist forms, and high-quality finishes, Aquanello Eterna combines luxury, comfort, and timeless elegance. The collection is designed for those who want to create a complete bathroom in which all faucets, showers, and accessories are perfectly coordinated.

A complete collection of bathroom faucets in a single design

The Aquanello Eterna series offers an exceptionally extensive range for the entire bathroom and toilet area. From elegant sink faucets, tall sink mixers for countertop basins, and built-in sink faucets to hand-wash basin faucets, luxury bathtub faucets, and freestanding bathtub mixers. Eterna also offers countless options for the shower, including thermostatic built-in shower sets, surface-mounted shower faucets, rain showers with hand showers, and complete shower columns.

The various shower faucets and rain showers are available with a range of control options, such as thermostatic mixers, separate shut-off valves, and integrated diverter valves. Choose from generously sized round rain showers with diameters of 20, 25, or 30 cm, with wall-mounted or ceiling-mounted arms, and combine them with matching hand showers, shower rods, and shower accessories. Thanks to the uniform design, all components can be harmoniously combined.

High-quality stainless steel with exclusive PVD finishes

Aquanello Eterna stands out through its use of high-quality stainless steel as the base material for the visible metal faucet components. The collection is available in four stylish finishes: brushed stainless steel, brushed gold PVD, brushed copper PVD, and matte black.

The gold and copper faucets feature a high-quality PVD (Physical Vapor Deposition) treatment. This technology ensures an exceptionally strong, wear-resistant, and durable surface finish. As a result, the warm gold color and elegant copper hue retain their luxurious appearance for a long time under normal use.

The matte black bathroom faucets have also been developed with a special focus on durability. These models feature a chrome-plated base layer beneath the black coating, ensuring strong adhesion and enhanced scratch resistance. As a result, the matte black Eterna collection combines a modern look with a robust finish designed for everyday use.

Thermostatic shower faucets and reliable built-in technology

In addition to design, technical quality is also a key feature of the Aquanello Eterna series. The thermostatic shower faucets ensure a comfortable and stable water temperature, while the practical control systems allow for precise adjustment of the various shower functions.

The in-wall components are equipped with integrated non-return valves, which help prevent unwanted backflow of water. This technical feature supports a safe and professional installation and complies with backflow prevention requirements applicable to European and British plumbing systems.

Thanks to its modular design and the separately available built-in components, trim pieces, and accessories, Aquanello Eterna offers extensive possibilities for both new bathrooms and renovation projects.

A stylish bathroom in stainless steel, gold, copper, or matte black

With Aquanello Eterna, you can easily create a complete bathroom in a single, uniform style. For example, combine a brushed gold sink faucet with a matching gold rain showerhead and bathtub faucet, or opt for matte black built-in faucets for a sleek, minimalist bathroom. The stainless steel and PVD finishes complement popular interior styles such as Japandi, modern luxury, natural stone, marble, and concrete-look finishes beautifully.

The series also offers matching hand-wash faucets and accessories for smaller restrooms, allowing you to carry the chosen design throughout your entire home.

5-Year Full Warranty on Aquanello Eterna

Aquanello underscores the quality of the Eterna collection with a full 5-year warranty. The combination of high-quality stainless steel materials, durable surface finishes, reliable faucet technology, and timeless European design makes Eterna an excellent choice for those who value long-lasting quality and everyday comfort.
