This style of tile is mostly used in older homes. Of course you can use it in a newer home if you love it and your style leans traditional. For me the downside would be there is a lot of grout with tile this small. A larger format is more practical, but it does change the look of the room. Were you going to use a green vanity similar to what is in your inspiration pic? Have you chosen tile for the tub surround and/or shower?

I was going to do this in our bathroom remodel but the floor space is so tiny there wouldn't be much repeat so we just went with all white of the same size hex. I'm not at all bothered by the amount of grout.

I think this look is really traditional but simple enough that it can transition to a modern look as shown in your pic. Go for it.

Thanks @kandrewspa. Yes, planning to use a similar vanity. Haven't chosen the tile for the tub surround yet but planning to keep it simple as it will be behind a shower curtain.

I love it!!!!

In a kds bathroom IMO the fewer grout lines the better and I like simple 12 x24 porcelalain tile one color for both bathroom floor and shwer walls matching grout and done so simple that wall color and accessories can be changed anytime . I dislike shower curtains but love glass shower screens that are hinged . Teach the kides now how to use a squeegee for the glass and the walls . Not sure if girls or boys but IMO counter space trumps 2 sinks for sure . I had 3 boys they never used the bathroom at the same time so no need for 2 sinks .

I have had several customers do those tiles. They love them. I do encourage anyone who uses them to get the best quality grout ( spend more to get the kind that is stain, old and mildew resistant.

Good luck!
