Roca T-500 Thermostatic Shower Mixer Tap

The Roca T-500 A5A2E18C00 thermostatic shower mixer tap is a wall-mounted exposed mixer designed to automatically maintain a comfortable and stable water temperature during showering. It features a chrome finish and incorporates Quick Reaction®, SafeTouch®, Safety 38º and Evershine technologies, combining thermostatic control, safety and ease of use.

The Roca T-500 series is designed to provide comfort, water and energy savings, and protection in everyday use. Its thermostatic system lets you preselect the temperature, while the 38-degree Celsius safety limit helps reduce the risk of accidentally selecting excessively high temperatures.

Thermostatic temperature control

Unlike a conventional single-lever tap, the T-500 uses thermostatic regulation to automatically maintain the selected temperature against normal pressure or temperature variations in the installation.

The user can select the shower temperature and control the water supply using the handles located at the ends of the mixer body.

Quick Reaction®: selected temperature in just a few seconds

Roca's Quick Reaction® technology allows the thermostatic tap to reach the selected temperature quickly. The manufacturer states that its thermostatic taps equipped with this system can reach the desired temperature in less than 3 seconds.

By reducing the time needed to manually adjust the hot and cold water mix, this technology contributes both to comfort and to avoiding unnecessary water consumption at the start of the shower.

Safety 38º for greater safety

The Roca T-500 incorporates the Safety 38º system, which sets a safety limit at 38 degrees Celsius.

To select higher temperatures, it is necessary to deliberately activate the unlocking mechanism, thereby reducing the risk of accidentally increasing the temperature during use.

This function is especially useful in homes with children, elderly people or users looking for additional protection against involuntary temperature changes.

SafeTouch®: safer surface to the touch

The SafeTouch® technology is designed to limit the heating of the metal surface of the tap.

Roca states that this solution prevents the outer body from overheating, helping reduce the risk of accidental burns when touching the mixer during showering.

Evershine chrome finish

Reference A5A2E18C00 is supplied in C0 chrome finish and features Roca's Evershine technology.

The Evershine coating is designed to preserve the characteristic shine of chrome and improve its resistance to corrosion, scratches and surface deposits produced during normal use.

Water and energy savings

Roca explicitly identifies the T-500 as a tap designed for water and energy savings. Thermostatic regulation allows the selected temperature to be reached quickly and avoids having to keep water running for long periods while manually adjusting the mix.

In addition, by maintaining the temperature automatically, continuous adjustments to the controls during showering are reduced.

Exposed wall-mounted installation

The T-500 is designed for exposed wall-mounted installation. The entire body remains accessible, making both operation and later maintenance easier.

The two hot and cold water supply inlets use G 1/2 threaded connections.

• Supply thread: G 1/2.
• Nominal distance between inlets: 150 millimetres.
• Adjustment range shown in the drawing: between 134 and 166 millimetres.
• Rosette diameter: approximately 65 millimetres.

Dimensions of the Roca T-500 A5A2E18C00

The official Roca technical drawing shows a compact horizontal design for wall-mounted installation.

• Approximate body length: 324 millimetres.
• Approximate projection from the wall: 77 millimetres.
• Rosette diameter: 65 millimetres.
• Nominal centre distance between connections: 150 millimetres.
• Connection adjustment: from 134 to 166 millimetres.
• Inlet connections: G 1/2.
• Bottom outlet: G 1/2.

These dimensions allow you to check compatibility with the existing outlets in advance, especially when the tap is being used to replace a previous wall-mounted mixer.

Bottom outlet for the shower set

The mixer has a G 1/2 bottom outlet intended for connecting the hose or the chosen shower set.

Reference A5A2E18C00 corresponds to the thermostatic mixer. The hand shower, hose and holder are not included in this individual reference; Roca also sells configurations and packs that combine the T-500 with compatible shower kits.

Compatible with Roca shower accessories

Roca associates this family with compatible shower accessories, including universal hoses and wall brackets for hand showers.

This makes it possible to complete the installation by selecting the hand shower, hose and holder that best suit the bathroom project.

Two controls for temperature and operation

The thermostatic configuration uses independent controls to manage temperature and water supply. This layout allows you to keep a comfortable temperature selected without having to search for the right mix every time you shower.

The temperature indicator and the Safety 38º system also make it easier to identify the safety limit during operation.

Ideal for renovations and replacement of wall-mounted taps

Thanks to its exposed mounting and the nominal 150-millimetre distance between inlets, the Roca T-500 is especially suitable for conventional wall-mounted installations and shower area renovation projects.

The connection adjustment range allows small differences in spacing between existing outlets to be absorbed, always within the dimensions specified by Roca.

Maintenance and spare parts

Roca keeps the technical exploded view for A5A2E18C00 identified, making it possible to locate specific replacement components for maintenance operations.

Components associated with the model include thermostatic tap handles and various internal parts and connection elements, making it easier to maintain the product instead of replacing the entire tap.
