Choosing the right ceramic trim for a tile project often comes down to shape before color. When you are restoring a mid-century wall or patching a section of ceramic tile, you may need only one trim piece. A long bullnose works as a straight edge, while a corner bullnose is shaped to wrap two sides at once. Pick the wrong profile and you are left with a gap at the corner or an exposed edge. These two glossy tiles take different approaches: one is a slim rectangle, the other is a square outcorner with two rounded edges. Both have the same 5/16-inch thickness, so the depth they sit at is not the deciding factor.
Quick verdict
Choose the Daltile Seafoam Green when you need a slim rectangular trim piece. Choose the American Olean Robin's Egg when you need a square outcorner piece with a finished radius on two edges.

At a glance, the two tiles are not interchangeable. One is a straight-edge trim, the other a corner trim. The glossy finish appears on both, so the color family and the footprint will drive your choice.
Where each tile wins
The Daltile wins for its long, narrow footprint. If you are lining a straight edge, the rectangular profile gives you a more continuous line than a square tile would.
The American Olean wins for corner trim execution. It is a square outcorner with a 3/4-inch radius on two perpendicular edges, so it can finish an outside corner cleanly.
Product notes
Daltile Seafoam Green Bullnose
This single ceramic bullnose is listed at USD 9.99. It is a 2x6 piece in a seafoam green tone that sits between green, gray, and blue. The tile is described as new old store stock, so it carries a period look. The listed length of 6 inches makes this the longer of the two formats, and the 2-inch width is more compact than the square option. The strength of this option is the long, slim shape for straight edges. On the color side, the closest chip appears a hair dark in photos, so the physical tile could look a little different from the image.
American Olean Robin's Egg Corner Bullnose
This single ceramic corner bullnose is listed at USD 17.50. It is a 4-1/4 inch square with a 3/4-inch radius on two perpendicular edges, in the Robin's Egg blue family. The main benefit is the outcorner shape: it is designed to wrap two perpendicular edges in one piece. It also adds glue to the installation options, so you are not limited to a thin-set bed. The trade-off is the price gap: this is the higher-listed-cost option, so it makes sense when the corner profile and the specific blue tone are what drive the decision.
Final choice by use case
For a slim accent edge, choose the Daltile bullnose. For a corner wrap, choose the American Olean corner bullnose.
