How to Grout a Rock Floor Shower
A rock floor is a stylish and interesting way to cover the base of a shower. It's also more complicated to grout than is a regular tile shower floor. Rock floors have wider grout lines than tile, and the lines vary in shape as part of the random look of the stone. Properly filling those lines with grout using a standard grout float is difficult, so it's best to use a grout bag, which operates under the same principle as a pastry bag, allowing you to target the grout and fill the lines. Does this Spark an idea?

Combine grout mix with water in a bucket, in the ratio specified on the grout packaging. Mix between a half-gallon and full gallon of grout, depending on the size of the shower area. Mix it with a drill and mixing bit, getting it to the consistency of thick mud.

Set the tip of the grout bag onto one of the spaces between the rocks, at one end of one line. Squeeze the bag with both hands to expel the grout into the space.

4
Drag the bag backwards along the line slowly, squeezing it evenly and letting the grout fill the space. Continue along the whole line, making sure the grout stays in the lines and not up on the rocks. Wipe off any grout that gets on the rock surface using a sponge.

Repeat for each line of the floor, filling them all.

6
Allow the grout to set for 30 minutes. Run the edge of the wooden spoon along each line to get them smooth and even with the rock surface.

7
Allow the grout dry overnight. Sweep it with a stiff broom to remove any residual loose grout from the surface.
