Pebble tile and river rocks have a natural affinity for bathrooms and spas.
That’s why pebble tile — also called river rocks — are being used as an alternative to field tiles for a back-to-nature effects. Whether used for flooring or shower and tub walls, the presence of small stones evokes the idea of brooks and riverbeds — places where running water can be soothing and elemental. The stones and pebbles are durable as flooring and the multiple pieces help keep them from becoming slippery when wet.
When I see walls and floors paved with pebble tile I’m always fascinated and want to run my hand over the surface. I also was surprised to see the wide range of variations in materials, colors and pebble tile surfaces — from color, to size, to type of stone, and even to blends of other materials. Like mosaics, pebble tiles are fixed to mesh backing so the overall pattern looks random and organic.
The most effective use of the river rock look — in my view — is in an all over bath [top]. While the tones are cool gray and taupe, there is a welcoming warmth to this shower. Plus the traction of a river stone floor is practical because it provides a surface with friction when wet. I also like that the stones are continued over the tub deck because I do feel it’s a bit difficult to mix them with other materials. A close look at the wall of the shower will, however, betray lines of the mesh behind the stones that keeps them in place.

I recently remodeled a bathroom with a new walk-in shower that has a river rock floor. The rocks vary in color primarily a gray-brown tone with a medium colored grout. When the floor is wet, we like the look so, we are now considering how to get that “wet look”. Can I apply a wet look sealer to the stones and grout?
I personally would not seal a river rock floor. The advantage is that it’s not slippery. A sealer could reduce the friction and make it slippery.
Having said that it might depend on the rock. I would check with the manufacturer and see what’s recommended for this particular material and go by that.
