Trendy and loosing ground in that regard. Water will pool in between the pebbles (not to mention soap scum, etc). Top notch tile professional required with lots of experience. Often they require taking the pebbles off the mesh and single setting them = time and the resulting $. You don't want to see the seams between sheets. They were a builder special trend option for awhile. Don't recommend unless you are designing for a specific style where they are appropriate and you have the qualified labor to execute, AND you are OK with the maintenance. Would not recommend.

My suggestion go get the sample board take off your shoes now stand on it in your bare feet see how you like it. IMO I never use white grout if at all possible it always discolors no matter what the grout maker says .I would not do those if you gave them to me. IMO the fewer grout lines everywher ein a bathroom is ideal I like 12 x24 porcelain tile on bathroom floors and shower walls with the same tile only smaller for the shower floor. Then if you want an accent tile one off center vertical stip and use that tile for a backspalsh you will enjoy it some much longer since it is simple and changing wall color or accents is easy.

When shopping for our guest bath tile for the floor, the pro told me that they are a tad uneven and not that comfortable. We chose this one-it’s not shiny but looks that way as my hubby just got out of the shower. It’s flat yet appears to have dimension in it. And the installer mixed in a type of sealer to the grout and it’s been so easy to keep clean. We don’t have any issue with soap scum in the grout whatsoever. The grout looks darker in the pic because it’s wet. We’ve had tons of compliments on it. But the shiny pebble may be just a tad uncomfortable-there again, just how long does one stand in their shower?

I had that in my condo. It was actually comfortable to stand on but like Dragonfly says, you need a top notch tile professional (which I had). He hand laid each and every single stone. He did not just put it down on the mesh. My shower was fine for the 6 years I was there and the person who bought it after me was fine with it too.

I have a very pale beigy yellow grout now in my shower in my house now, and after 4 years it looks as good as the day it was installed. The newer grouts are so much better.

We have a very similar pebble tile in a guest bath at our beach house. I loved the look but once I actually used the shower I realized it wasn’t that comfortable to stand on. Not terribly uncomfortable but glad it wasn’t in the primary shower. We did not have an issue with installation about eight years ago when we redid this bath.

Seems it would be hard to keep clean bc of water pooling and soap scum.

If you pitch the slope of the shower slightly higher, that helps with the water not ponding in the hollows between stones. It still isn’t comfortable.

I live in the mountains and most homes in my area are log cabins or such. The rustic shower look is obviously pretty popular. When these first became a thing I saw them in every remodel, or new builder spec house. Then they started using the cut stones, they look similar but are cut so the surface you are standing on is leveled out. Most people have switched to this type of pebble that I've seen. I stayed in an Airbnb that had the cut pebbles and found it to be very comfortable on the feet, but I can't speak to upkeep.

Patricia Colwell beat me to it - try standing on a sample piece to see how it feels.

If you must use this style then select the pebble tile that has been sliced flat.

Thank you everyone. Your comments are SO helpful.

What Beverly said. They make pebble tile that is flat on top which makes it way more comfortable to stand on.

We have the sliced pebbles in both master and guest. We have had a ton of problems with one shower, but the surface of the tiles wasn't one of them. They're comfortable and as our sloping gets better, hold/pool water no worse than square tiles of a similar size.

Two of our showers have rounded pebbles. They do not pool water, are easy to clean, are non slip, comfortable to stand on and fit in nicely with our decor that makes subtle use of natural materials. We tiled both showers ourselves.

My last two showers in my homes had the natural pebbles. We loved them, easy to stand on and we had great installers so no issues there. They are a bit like rain heads, you love them or hate them.
