Hello,

Grout is used here, yes. This particular series is rectified, meaning saw cut on all four edges so it can be set with a tight grout joint. We recommend a 2/16" grout joint for a rectified tile. Thanks!

We're doing a similar install in one of our new custom homes! Wood Replica Porcelain Tile is becoming a popular contemporary look in homes this year. It's great because it resists scratches, chips, and moisture, is easy to clean and maintain, and the best of all - it's typically cheaper depending on the board size you use. Most Wood Replica Tile uses grout. But you'll have to be very careful when picking it out, a few shades off and it will look like tile. The next thing to consider is the way they are sanded, which will determine how close the boards will be to each other.

To give you a visual, the first image is an example of flooring with an unsanded/fine-sanded grout. The second image is an example of flooring with standard sanded grout lines.

Hope this helps!
