Groutr: Grout Color Visualizer

Choosing the right grout color can make or break your design. Groutr lets you see how any grout shade — or even multiple shades — will look on your own tiles and mosaics before you commit.


Take a photo of your project, and Groutr automatically detects the grout lines. From there, you can:

- Try any color: pick a custom shade or colors from real grout brands

- Compare side-by-side: preview up to 4 colors at once

- Visualize multi-color grout: paint or recolor lines individually for creative designs

- Edit with precision: erase or redraw to refine the detected grout lines

- Simulate grout on all tile types: mosaics, ceramic, hex, pebble pavers, stained glass, and more. If it needs grout, Groutr can visualize it.

Whether you’re planning a bathroom remodel, designing a kitchen backsplash, or finishing a mosaic artwork, Groutr uses your own images to help you explore options, avoid costly mistakes, and design with confidence.
