I’m so excited to share with you our powder bathroom floor today! We’ve been working on laying a cute little pattern in penny rounds over the last week and we’re so happy with how it turned out! The powder room is really squared off: At 22 square feet, it’s small, so the angles feel especially sharp, and the room seems especially rectangular. Also, the wallpaper we chose is striped (see all the plans here). Tiny round tiles felt like the perfect, soft, charming touch.

We got all of the supplies we needed for this project at our local Tile Shop. Which is, actually, SURREAL to say because we have been working with The Tile Shop since 2012 in our VERY first kitchen. (see that marble backsplash here!) and then again for our wood tile floors in our rambler, and we most recently used all of their pretty limestone in the primary bathroom in our Modern Cottage–and we never stepped foot in one of their showrooms until this project. It honestly felt like Disneyland. The associates were really helpful and knowledgeable and it was a one stop shop for everything we needed for this project. And more. Meaning…I already started eyeing tile for future projects. :)

Here’s everything we needed for this project!

The Tile Shop actually had some really cool ready-made mosaic options for penny rounds and beyond, but since it was such a small room, it felt like a good time to try something creative and try my hand at my at a custom pattern. I printed out a white sheet of paper with true-to-life sized penny tile, and I started coloring in different blocks. This was such a great first DIY project in our new home because it’s really not a heavy lift. There’s no power tools or tile cutting involved. You can easily cut the mesh backing of tile sheets with sheers to whatever size you need, all the way up to the border of your room.

First things first!

  1. Lay down a subfloor

Our contractors removed the wood flooring that was in the powder room previously, and we started with a plywood subfloor. You can’t lay tile on plywood because wood is a living material, and it “breathes” through the seasons, causing tiles to crack and break away from the floor. So we installed 1/4-inch Hardie board. It’s so easy to cut, you don’t even need a saw. Just score it with a razorblade knife and snap it. Using a 1/4-inch trowel, apply mortar to the plywood and then secure the Hardie board. For additional security, screw down the board every 12 inches. Apply mesh tape to all of the seams and, using a spackle knife, run an extra layer of mortar on top of that. Smooth it out, and let this dry for at least eight hours, or overnight.

  1. Plan your border

When you’re ready to lay your tile, dry-lay your border, and play with the white tile sheets on the interior (or inverse it if you’re feeling spunky!). One thing to note: There’s a straight side of penny tile, where the pieces align perfectly, and then there’s an offset side, where a “straight” line is more …toothy. Don’t fight it! Once I embraced how the tile lays and fits into each other, the pattern-making got really fun and easy. We applied the straight border on the long side of the room and the offset border on the short side of the room.

Practice with the placement of the “straight” side of the penny tile mats and the offset side until the corners are sharp and the border is exactly how you want it. Hold off designing your interior pattern for now…if you can. I should note here: –we finished the edge of the tile where it meets with the hallway, with a black Shluter edge that will meet our wood floors going down in the hall this week!

  1. Mortar the tile in place

Working in sections, remove a portion of the tile. Apply a thin layer of mortar using a narrow-tooth trowel. (The smaller the individual tile, the smaller the teeth on the trowel.) To ensure you’re not applying too much mortar, make sure the trowel teeth scrape on the floor. Lay the tile border and sheets in sections, pressing each piece into the mortar. Allow to dry for at least eight hours.

  1. Design your interior pattern

After all the tile is laid and has dried, you are ready to start laying the pattern inside. Pop a few black tiles out from the mesh sheets, and begin placing them (dry) over the mortared-in-place white penny tile. Place all of the black tiles, planning the entire pattern and its spacing to make sure you’re happy with where it starts and finishes. Use a dry erase marker to mark the location of black tiles, if you wish. When the pattern is exactly the way you want it and the spacing is right, use a screwdriver to pop out the mortared white tiles, replacing them with black tiles. We used a plastic bag with a tiny hole in one corner (like a pastry bag!) to apply a tiny dollop of mortar on the back of the black tiles. I call this the pop-and-place method :) Let the black tiles dry/set overnight.

Below is before grout.

  1. Grout your tile

We decided to go with a warm gray grout.

Using a grout float, skim a layer of grout over the tile. Hit your grout lines at every angle — pushing and pulling the grout backwards and forward until grout is tightly around every circular tile. Scrape off any excess. Using a sponge and warm water, continue to wipe the tiles clean of grout. Important: Work in five-minute sections. The grout dries over the tile quickly, making it hazy.

  1. Acid wash the tile

Even if you work quickly, you’ll likely have SOME grout haze over the tile. Let the grout dry overnight, and then, wearing gloves and using the abrasive side of your sponge, scrub the tile with an acid cleaner (a mix of vinegar and water also works). Pro tip: Don’t use the acid cleaner on anything but ceramic tile – it’s too abrasive for natural stone materials.

The end result is a double black border around the perimeter of the room and then 17 black “diamonds” arranged in the interior. — They’re not really diamonds. They’re… asterisks?

Such an easy and impactful DIY. If you have a small space, I hope you try your hand at designing your own custom pattern. It’s really the most fun you can have with penny tile.

I’m honestly so in love with how it turned out and think it’s going to be the perfect little bathroom for all of our guests to freshen up in over the coming years. And with such a small space, the extra work required to make it happen was definitely worth it.

Next up! Paint and wallpaper!

What do you think?

  1. Marianne says:

    Incredible ! I love it 😍

  2. Deb says:

    LOVE IT! The pattern you came up with is so fun, but still classic. Can’t wait to see it all come together!

  3. Caitlin Rose Low says:

    I love it!! Although, admittedly, I stared at this for such a long time and felt perplexed. And then I figured out it was the thick black line of tile in the doorway. It makes absolute sense in order to center the pattern in the bathroom, but there is zero chance if I were doing this, that I could have figured out that solution. I would have probably given up and not done the border at all. This is absolutely why you are great at what you do. I imagine you thought about it for awhile, though it seems effortless!! I’m excited to see it all come together!

  4. Angela Gibson says:

    I adore how this turned out! So talk to me about cleaning… I’ve always avoided penny rounds because the grout maintenance seems out of control, but this has me rethinking my life choices!

  5. Elizabeth says:

    Like everything else you do…. Absolutely beautiful! Can’t wait to see what you do with the rest of the room and house and so excited that you will have one room finished!

  6. Ryli says:

    What a special pattern you created! Love the idea of creating a “unique to you” design with these tiles. Thank you for the step-by-step process and method for installation, it’s so helpful. Saving this for a future DIY.

  7. Laura C says:

    This looks great – love the pattern you invented. One thing I found really helpful when laying penny tile was to use a flat piece of scrap wood (a little larger than one sheet of tile is ideal) to push down on the tile and get it all evenly embedded in the mortar.

  8. Roslyn says:

    This floor is amazing! I paid a professional to penny tile my bathroom and you can clearly see the grid outline of the sheets. I HATE IT, but he is standing by the work. Some of the sheets are pushed so close to another there is barely any grout between tiles and others are further apart you can see big fat grout lines. Was there anything you did to get yours so perfectly spaced each time?

    • Julia says:

      We have a MUCH smaller floor, so that definitely worked in our favor. But I kept squinting to make sure everything looked uniform throughout the process. I have heard penny tiles are notorious for that, though!

    • Laura C says:

      That’s a bad tile job. You’re supposed to stagger the sheets to minimize this, and you have to pay really close attention to spacing to make sure everything is even. I felt like my eyes were going nuts when I did a large bathroom floor in penny tile, but the attention to detail paid off.

  9. I love how this turned out, the penny tile looks like it has been there forever and always!

  10. Carriereen says:

    So cute, and so glad that you are getting back to your DIY roots. I felt so disconnected once you did your kitchen at the last house.

  11. Colleen N says:

    Love the pattern. I got so sick of our old linoleum floors that I ripped them out. Now stuck at the hardie backer step. How did you cut around the toilet opening? Or do rounded cuts?

  12. Jenny B says:

    Hi! So cute! It looks like the pieces on the side aren’t full tiles, but you said you didn’t have to cut any – how did that work? Thx!

  13. Kate says:

    What a charming little bathroom!! And a fun nook to do something creative + likely a surprise when you walk in!! Love it – taking notes for the house we’re HOPEFULLY going to buy here soon…

  14. Callie Barber says:

    I love it! It turned out so beautiful. Is the pennytile glossy?

  15. Meg says:

    What did you all use to separate the tile from the main flooring? I remember you mentioned it in your stories but it expired before I could go back for the info.
    Also, cannot wait to try this in our half bath!

  16. Heidi Harris says:

    Hope to do this in our main bath of our new build!

  17. Brenda says:

    Love it!!

  18. Wendy says:

    Looks amazing! I want to do some now!😄

We recently painted our study a dark, moody green color. This is after we first painted it a muddy green, then repainted it a blue-gray. I guess what they say is true; third time’s a charm! The journey was worth it, though, because I’m so in love with this glossy green in contrast with the […]
