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 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.
