In contemporary bathroom design, every element plays a fundamental role in creating balanced and functional spaces. The Tres B-system collection embodies this philosophy with a range of concealed thermostatic shower mixers that combine clean lines, carefully considered proportions and sophisticated aesthetics.
A design that brings lightness to the space
Its most distinctive feature is the subtle separation between the mixer body and the wall, creating an elegant floating effect. This detail adds depth and visual lightness to the overall design, transforming a functional element into a feature seamlessly integrated into the bathroom architecture.
Thanks to its compact design and the reduced depth of its visible components, B-system optimises the available shower space and promotes a clean aesthetic, allowing materials, textures and light to take centre stage.
Thermostatic technology for a comfortable shower experience
Beyond its design, B-system incorporates technology developed to deliver a precise, safe and comfortable shower experience.
Its thermostatic system maintains a constant water temperature, even when pressure or temperature fluctuations occur within the installation. The Tres Therm 77® thermostatic cartridge offers temperature stability within ±1 °C, ensuring a pleasant shower experience without sudden changes.
Safety is also an essential part of its design. The system features a safety stop at 38 °C to help prevent accidental scalding. To select a higher temperature, the safety button must be pressed while turning the control handle.
A combination of technology and ease of use that allows users to enjoy water with confidence and peace of mind.

Intelligent installation, impeccable aesthetics
B-system has been designed to offer advantages for both users and installation professionals.
Its concealed installation box allows mounting from either the front or the back of the wall and is suitable for both masonry walls and lightweight construction systems, such as plasterboard.
It also incorporates technical solutions that enhance installation safety and comfort:
- Watertight box and waterproof seal: help prevent water from penetrating the wall in the event of a leak.
- Thermal insulation: reduces heat transfer from the brass body to the wall.
- Acoustic dampers: minimise the transmission of vibrations and noise to the installation.
- Adaptability: the separation between the decorative trim and the wall facilitates installation even on slightly uneven surfaces.
The result is a solution that combines technical reliability, ease of installation and carefully refined aesthetics.
Versatility to create a tailor-made shower
Every bathroom space is different. That is why B-system offers 2, 3 and 4-way configurations, allowing the shower experience to be adapted to the needs of each project.
With a simple turn of the diverter, users can select the desired water outlet and enjoy different combinations of overhead showers, hand showers and other functions, depending on the chosen configuration.
This flexibility makes B-system a particularly attractive solution for residential and contract projects, where functionality must coexist with aesthetic consistency.
Finishes that define the bathroom's personality
The tapware finish is an essential element in bathroom design. B-system is available in a variety of options that allow spaces with distinctive identities to be created, from minimalist compositions to warmer and more sophisticated interiors.
The understated character of Matt Black, the elegance of Steel and the distinctive personality of special finishes allow the collection to blend into different architectural styles.
The range also includes finishes featuring PBT® (Protection Brushed Technology), such as Cava Gold, Graphite, Black Bronze and Volcanic, developed to combine distinctive aesthetics with exceptional surface resistance.
This variety allows the tapware to be coordinated with wall coverings, furniture and other bathroom elements, creating spaces where every detail contributes to a unified design vision.
B-system: the balance between design, technology and well-being
With B-system, Tres demonstrates that true comfort lies in the balance between aesthetics and functionality.
Its floating-effect design, thermostatic precision and versatile configurations make this collection an ideal solution for those seeking a shower experience where every detail matters.
Because design is not only something to admire. It is also something to feel.
