The model BLV-29745-BK-3 is a shower mixer from the brand BENLIVE, finished in a matte black tone. This matte black shower mixer is specifically designed as a concealed installation unit, meaning the main valve body is installed inside the wall, leaving only the control handle and trim plate visible. This concealed shower mixer functions as a hot and cold mixer, allowing the user to adjust water temperature smoothly. It is an excellent choice for modern bathrooms, luxury hotels, or contemporary residential showers where a bold, sophisticated, and minimalist look is desired.

Materials and Construction

The main body of this brass shower mixer is constructed from solid brass, a material valued for its durability, resistance to corrosion, and ability to hold a high-quality finish over many years. The cartridge inside is a ceramic cartridge, known for its smooth, precise operation and long service life, as it resists wear and is less likely to develop drips or leaks compared to rubber washers. The entire exterior is finished in matte black, giving this black shower mixer a sleek, modern, and elegant appearance that is resistant to fingerprints and water spots. The matte black finish complements a wide range of contemporary bathroom styles, including industrial, minimalist, and urban designs.

Dimensions and Installation Requirements

The shower mixer has a size of 140 millimeters by 180 millimeters. This measurement typically refers to the dimensions of the concealed trim plate or the distance between the center of the water inlets and outlets. Installation is concealed, which requires the valve body to be mounted inside the wall before tiling or finishing. This behind-the-wall installation leaves only the elegant matte black trim plate and control handle exposed, creating a clean and uncluttered look in the shower area. The connection thread is G3/4, which is a standard three-quarter inch BSP thread, larger than the G1/2 thread found on basin faucets. This larger thread size allows for higher water flow rates suitable for shower systems. The concealed shower mixer is designed for professional installation during new construction or bathroom renovation projects.

Internal Mechanism and Operation

Inside the concealed valve body, a ceramic cartridge controls the flow and mixing of hot and cold water. This ceramic disc cartridge is known for its smooth, precise operation and long service life. The user adjusts the handle to increase or decrease flow and to blend hot and cold water to achieve the desired temperature. The hot and cold mixer cartridge provides reliable performance and consistent water temperature control for a comfortable showering experience.

Working Pressure Range

The matte black shower mixer is designed to operate within a working pressure range of 0.05 to 0.6 MPa. For practical reference, this equals 0.5 to 6 bar, or approximately 7.25 to 87 PSI. The lower limit of 0.05 MPa means the mixer can function even with low-pressure water supply systems, such as gravity-fed tanks. The upper limit of 0.6 MPa makes it suitable for most standard household mains pressure systems without risk of damage. This working pressure range of 0.05-0.6 MPa ensures compatibility with a wide variety of residential and commercial plumbing setups.

Warranty

The BENLIVE shower mixer comes with a warranty period of two years from the date of purchase. This two-year warranty typically covers manufacturing defects, any failure of the ceramic cartridge, and deterioration of the matte black finish under normal residential or commercial use. The warranty does not cover damage resulting from improper installation, misuse, excessive water pressure above 0.6 MPa, or damage caused by abrasive or chemical cleaning agents.
