5 Important Concepts

As Seen On
Pebble Tile Shower Floor

Pebble tile shower floors can look amazing or bad, really BAD.

Today we’ll share 5 important tips for installing awesome pebble stone shower floors.

Even seasoned installers can overlook these concepts. But you’ll be ahead of the game if you watch our short video.

Let’s dive in!

 

Pebble Tile Shower Floor Tips

Building showers can be stressful for beginners.

Fortunately, new shower systems like Schluter’s KERDI kit, KBRS’s Tile-Basin, and Wedi’s Fundo Primo make it much easier.

Every shower pan should be flood tested for 24 hours. Flood testing ensures shower pans can hold water and that there are no leaks.

Once the flood test is complete, tile setting can begin.

Pebble stone shower floors are a different best, and do require additional planning.

These 5 tips will help a ton.

 

Tip #1: Install pebble tile stone floors first

The rationale for tiling the floor first is simple, expansion and contraction joints will be hidden by wall tiles. Remember, TCNA (Tile Council of North America) guidelines stipulate expansion and contraction joints for shower floors and walls. Read their handbook for more tips.

 

Tip #2: Pick stones with minimal glue 

Steve does a great job explaining this in the video; pebble tiles are adhered to mesh using adhesive. Excess adhesive on the tiles prevents them from bonding to thin-set mortar. Eventually the pebble tiles will detach from the floor and create a huge MESS.

 

Tip #3: Dry fit pebble stone sheets 

Every pebble stone sheet is different, which is a pain in the butt. Dry fit pebble stone sheets over the shower pan and label them with painter’s tape. Odds are good that the layout won’t be perfect but don’t let this lead to frustration. Pebble stones can be set on the floor one by one and this doesn’t take a long time.

 

Tip #4: Use white thin-set mortar 

Gray thin-set mortar has color and pigment in it. This can transfer to pebble stones and cause them to discolor over time. Thus, use white thin-set mortar to prevent this from happening. Furthermore, use Schluter’s ALL-SET to maintain the Schluter KERDI shower kit warranty.

 

Tip #5: Make pebble stone sheets tight 

Rookie’s make the fatal mistake of not pushing pebble stone sheets tight to each other. This in turn makes the outline of the sheets visible after grouting the shower floor.

If sheet outlines are visible either push them closer together or pull pebbles off the sheet and rearrange them to eliminate the outline.

Watch our video to see Steve explain these tips, you’ll be way ahead of the the game

 

What’s Next

Pebble tile shower floors are great but just make sure the outline of sheets cannot be seen!

    Great tutorial. Question was the white thinset Steve was using modified or unmodified?

    1. If I remember correctly it was Schluter’s ALL-SET, which is approved over Kerdi

  2. Nick Young says:

    Did you grout the floor before installing the wall tile?

    1. Nick, we tiled the entire shower then grouted the pebble stone. Once that was done the shower walls were grouted, too. We used Mapei Ultracolor Plus FA for both.

  3. K G Blomgren says:

    Tip #2 is VERY important. I had a custom tile job done in our master bath. It included a flat pebble shower floor which WAS absolutely beautiful. However, within a few weeks the stones came loose and the loose stones broke up the mortar joints. The entire shower floor will have to be redone.
    Why did this happen? The backs of the stones were covered entirely with a soft mastic to glue them to the mesh, and thinnest does NOT bond to mastic. What a mess!

  4. Forrest Walsh says:

    If one has the round shaped Pebble stones, how deep does the grout have to be or more importantly how shallow can it be so you can see more of the stones and still let the drainage work properly?

  5. Sharon says:

    great help, my question is do they hold water once all is said and done. I do not want mold to grow in the shower. . . .YIKES
    Thank you,
    Sharon

    I have used thinset mortar over same tiles on my Krbs shower tray..have not grout yet, but some areas are missing peebles, can I use an adhesive to glue the few peebles before grouting ? Or use again mortar again, and place the missing peebles over the yesterday dried mortar ?

  7. connie M says:

    We have a pebble title shower floor. My husband attempted to clean it with CLR, and it has taken the shine off the floor and made the floor look worse. Is there anything I can do to repair and reseal it back to it’s shine?

  8. Allen says:

    In your video you show straight cut pebble stones. If you are utilizing a wet saw, how do you cut the small stones safely?

  9. Nathalie Bleach says:

    Hi Jeff. We are using the exact same kerdi system and almost identical tile. Do you tile right up to the drain opening and then place the drain grate or do you allow for any space around the drain grate? Unsure how to install the grate with these floor tiles.
