Corner Trim & Cove Base Tile

Your Guide to Cove Base and Corner Trim

What Is Cove Base?

A tiled wall isn't truly finished until the spot where it meets the floor looks just as polished as everything above it. That's the job cove base does. It's the curved trim that runs along the bottom of a tiled wall, easing a sharp 90-degree angle into a smooth curve so water and debris are less likely to collect in a hard-to-clean corner. You'll also hear it called coving, or sanitary cove base, especially in commercial kitchens and other sanitary installations where an easy-to-clean floor-to-wall transition is important. We carry cove base in ceramic, quarry, and porcelain, in matte, glossy, and honed finishes, so you can carry your wall's look all the way to the floor.

Inside and Outside Corner Trim Completes the Run

A great cove base installation needs the right corners to match. A straight run only works on a flat wall, so the moment that wall turns a corner, you need a piece shaped to follow it. That's corner trim. An inside corner curves inward, perfect for the inside of an alcove or a shower niche. An outside corner curves outward, ideal for the corner of a column or a half-wall, and comes in a left and a right version so the curve always faces the right way.

Looking for an even more seamless look? Bullnose Tile solves a similar problem with the curve built right into the tile itself, instead of a separate corner piece.

A metal, stainless steel, or L-shaped profile trim is another option some installers reach for, but that's a different product made of metal or PVC rather than tile. We keep our focus on tile-matched corners in ceramic, quarry, and porcelain, so every piece blends with your cove base instead of standing apart from it.

Stairs Deserve a Finished Look Too

Stair coping brings that same polished finish to tiled stairs, capping the front edge of each tread with a built-in anti-slip texture that gives every step solid footing. A stair corner does the same direction-changing job as an inside or outside corner, sized for wherever a staircase meets a landing or wall.

Where Cove Base and Corner Trim Belong

This finishing touch goes anywhere a tiled wall meets a floor or another wall: a bathroom or shower floor-to-wall transition, the inside corner of a shower niche, the corner of a backsplash wrapping a wall edge, or a commercial kitchen floor built to meet sanitary code. Stair coping and stair corners bring that same finished, secure feel to tiled staircases and landings.

How to Choose Cove Base and Corner Trim

Order Cove Base and Corner Trim Together

A little planning up front makes for a seamless finish later. Walk the room and count up your straight runs and your corners before you order, so everything arrives ready to install as one cohesive look. A corner in a slightly different color or finish than your cove base will stand out right where you want things to blend.

Pick Inside, Outside, and the Right Direction

Inside corners and outside corners each play a different role, and a left outside corner needs its right-hand match to complete a run. A quick walkthrough before you order saves you a second trip later.

Give Stairs a Little Extra Thought

For stair coping, start with the grip your tread needs, then find the closest color and finish to go with it. A little texture goes a long way underfoot, and you'll still land on a great match for your tile.

Order by the Piece

Cove base and corner trim are sold piece by piece, not by square footage or a running length. Measure your straight runs, count your corners and tread edges, and order a couple of extra pieces in case one is damaged or cut wrong during installation.
