Tile Trims Guide: How to Choose & Install Tile Trim for Walls, Floors & Counters
When planning a tiling project, the finishing touches are just as important as the tiles themselves. Tile trims not only protect edges and corners from damage but also give your walls, floors, and countertops a polished, professional appearance. In this guide, we’ll explain the different types of tile trims, how to choose the right ones, and tips for installation so your tiling project is both beautiful and durable.
Why Tile Trims Are Essential
Tile edges are vulnerable to chipping, cracking, and general wear. Tile trims serve as a protective barrier, especially for high-traffic areas, stairs, and wet zones like bathrooms. They also create clean lines and finished edges, improving the overall look of your project.
Different trims serve different purposes:
- Corner trims: Protect sharp edges and corners from impact. Shop corner trims
- L-shaped trims: Finish external corners for walls or countertops. Shop L-shaped trims
- Outdoor or 20mm porcelain trims: Provide durability against weather and outdoor wear. Shop 20mm porcelain trims
- Decorative trims: Add style to plain tiles, such as listello or quadrant trims. Shop decorative trims
Choosing the Right Tile Trim for Your Space
Choosing the correct trim depends on three main factors:
- Tile thickness: Match trims to your tile depth, for example, 20mm porcelain tile trims for thicker tiles.
- Location: Bathrooms, kitchens, and outdoor areas each require trims suited to moisture, temperature, and traffic.
- Style: Profiles like square edge, angular, or rounded trims can complement your design while protecting tiles.
Material also matters. Popular options include aluminium, stainless steel, brass, and PVC. Aluminium and stainless steel are ideal for modern, sleek looks, while brass can add a classic touch. PVC trims are budget-friendly and water-resistant, perfect for bathrooms and wet areas.
