Functions and Benefits of Quadrant Trim

Quadrant Trim is an essential building material used for finishing internal corners in modern construction. It is designed to cover small gaps where a wall meets another wall or ceiling, and to add a decorative finish to the edges of walls, floors, and ceilings.

Same as the angle, also a retro fit, this trim is designed to finish an internal corner. It is slightly flexible and can mould around slight bends in a wall where a corner isn’t necessarily perfectly straight. It is available in chrome or white, both made of plastic. The benefit of this trim is the fact that it is a retrofit trim, so it can be easily installed after the installation of bathroom cladding or after the installation of windows.

Quadrant Trim comes in different sizes that cover from 1mm to 15mm, depending on the size of the trims. Trims come in 12.5mm, 17.5mm, and 19mm sizes. It is lightweight and easy to install with adhesive. You can easily cut it with a fine-toothed saw to fit the exact dimensions you need.

Quadrant Trim for Diverse Applications and Colours

Our Plastic Quadrant Trim is not only available in two main elegant colours, white and chrome, but also designed for various applications including bathroom and shower environments. Each colour option provides a unique and stylish finish, perfect for enhancing the design of any construction or renovation project, whether it’s for a standard room or a specific wet area.

Shower Quadrant Trim:

Our Shower Quadrant Trim is specially engineered to withstand the moisture-heavy environment of bathrooms. It serves as a waterproof barrier that prevents water infiltration into wall joints, a critical feature for shower areas and bathtub edges. This trim not only secures these wet spaces against water damage but also enhances their visual appeal. Its sleek design integrates seamlessly into various bathroom styles, adding a polished look that uplifts the overall aesthetic.

In addition to its elegant appearance, the Shower Quadrant Trim is prized for its practical benefits. Its moisture resistance ensures lasting durability and a mold-free environment, crucial in maintaining a healthy bathroom. The ease of maintenance is a standout feature; a simple wipe-down keeps the trim looking new, making it an ideal solution for both high-traffic family bathrooms and sleek, modern en-suites. At MB DIY, we prioritize quality and functionality, ensuring our Shower Quadrant Trim meets the rigorous demands of bathroom design and usage.

Bathroom Quadrant Trim:

Our Bathroom Quadrant Trim is designed specifically to meet the unique requirements of bathroom spaces. It is crafted to blend effortlessly with a range of bathroom décors, adding an elegant finish to key areas like vanity units, sink edges, and around mirrors. This trim plays a crucial role in ensuring smooth transitions between different surfaces in the bathroom, contributing significantly to a cohesive and visually appealing space.

The trim’s design not only enhances the bathroom’s aesthetic but also offers practical functionality. It aids in creating a polished, seamless look that elevates the overall feel of the bathroom, making it an ideal choice for both functional and decorative purposes. This balance of style and utility makes the Bathroom Quadrant Trim an essential component in modern bathroom design.

White Quadrant Trim:

White Plastic Quadrant provides a subtle and classic finish that blends seamlessly with most interior design styles. It is perfect for achieving a clean and understated look in areas where walls and ceilings meet. The white Quadrant Trim creates a seamless transition that enhances the overall aesthetic of the space.

Chrome Quadrant Trim:

Chrome Plastic Quadrant adds a touch of sophistication and modernity to any interior design. It is perfect for adding a stylish finish to the edges of walls, floors, and ceilings. The chrome Quadrant Trim creates a sleek and bold transition that catches the eye and adds an extra layer of elegance to any space.

No matter which colours you choose, Quadrant Trim is a versatile and functional material that can enhance the overall design of any construction or renovation project. So whether you’re looking for a classic or modern finish, white or chrome Quadrant Trim is the perfect choice to elevate your design to the next level.
