SO, let me show you what’s done. First, just look at that pretty drop in soaker tub surround in Jeffrey Court Stargazer Tile. I found that tile at Home Depot.

I trimmed the corner with Schluter Edging Trim to give the tile a nice, clean finish where they meet. Schluter is that metal looking edging you see on tile sometimes.

This was my first time using Schluter Edging on a DIY tiling project. I was a little worried when I bought it, but it’s actually really easy to use and install.

I'm so glad I decided to go for this marble mosaic tile bathroom design! How pretty is that MSI Calacata Blanco Marble tile?! #AbbottsAtHome #MosaicTile #MarbleTile #BathroomTile

The MSI Calacatta Blanco tile I used for the tubs marble mosaic tile backsplash has a pretty leaf design that I love. I found this at Home Depot too.

It’s also trimmed out with the Schluter edging on the top and right sides. The tub is the Mirabelle Soaking Tub, in 72″ x 36″.

It’s no longer available on Amazon, but they still have a bunch of great deep drop in soaker tubs. And a couple weeks ago, I shared a video walk through for framing in a new shower niche.

I matched my mosaic marble tiles with this pretty 4 x 12 marble subway tile ran vertically. #AbbottsAtHome #MosaicTile #MarbleTile #BathroomTile

Here’s that niche getting it’s new tile. It’s looking so great already. I used 4″x12″ Marble Subway from Floor and Decor here. OK, let’s get to mosaic tiling tips and tricks.

How To Install Mosaic Tile

Tip One – Make Straight Cuts

My number one tip for getting a professional install look is to always cut straight lines. I prefer to use a wet saw when cutting marble tile. I always use a wet saw on stone tile like this marble mosaic tile.

If the outside lines on your marble tile aren’t straight, it won’t look professional. And, it will always drive you crazy.

When you cut marble mosaic tiles, it’s best to use a wax pencil (also called a China Marker) to mark the cut line on the tiles before cutting. That line makes a handy guide for making straight cuts.

Cutting straight lines on mosaic tile takes longer than it sounds. When you’re in the middle of installing tile & your mortar is drying fast, you don’t have much time for cutting small pieces.

So, when you are rushed, you cut the little pieces without measuring properly or marking with your grease pencil. Instead, plan your cuts and get them done before applying mortar to the wall.

Tip Two – Cut Tiles Before Mixing Mortar

I try to make as many cuts as possible for a mosaic tile backsplash before I even mix my mortar. I marked and cut my mosaic tiles beforehand to get nice clean lines.

If I tried to cut my tiles after mixing the mortar, I would have had mortar drying on the wall and a much harder time getting things perfectly straight.

Most beginners find it easier to layout all of the cut tiles for an area or section before mixing the mortar.

Tip Three – Buy the Tile for the Entire Bathroom Before Starting

Make sure you pick and buy all of your wall and flooring tile for the entire bathroom before you start tiling your bathroom.

I’ve seen a few DIY projects turn into big fails when a tiling project is started with one type of tile that the user can’t get enough of to finish the bathroom.

I used both styles of the mosaic tiles from the tub in the shower too. I also used a 4 x 12 marble tile I found at Floor and Decor on 2 shower walls too.

I must have gone to Lowes, Home Depot, and Floor and Decor half a dozen times each when I was trying to decide which tiles to use.

So many choices, not enough time. 😉

That small marble mosaic tile I installed in our shower is beautiful, but I definitely spent a lot of time cutting tons of small pieces and lining them up perfectly. You can see all of the before and after master bathroom remodel photos in another post.

Tip Four – Plan the Layout and Every Detail Before Starting

Another important tip for mosaic tiling beginners is to really spend time thinking about every step of a project before starting.

I spend a lot of time thinking about where I need to start a tiling projects and which tiles I want in different areas. For example, you have to tile shower floors and the threshold before tiling the walls.

So, before starting I had to think about which direction I wanted to lay the tile, I had to cut and dry fit every tile, and get the mortar ready. Then I worked from the inside wall out to layout that mosaic tile.

I went with a large marble subway and 2 marble mosaic tile patterns in this bathroom makeover. I cannot wait to see this finished, guys! #AbbottsAtHome #MosaicTile #MarbleTile #BathroomTile
Here’s a look at the 3 types of tile I used in my shower. That large 40″ wide, 6″ deep Marble piece is called a threshold.

Tip Five – Details Make A Room Look High End

I used a Schluter edging, a solid marble threshold, and bullnose detail tile in our shower too. Those detail pieces make the whole design of a bathroom look high end.

Floor and Decor sells 6″ wide Shower Thresholds. Make sure to get the “curb” cut style so that both sides have a nice polished edge.

Some of the thresholds are cut for window ledges. That cut style has only 1 polished side.

I used Schluter edging on the outside edges of the shower and bullnose tiles along the top to give the whole shower extra style.

If you look closely where the tile meets the corner of the wall, you can see I used Schluter aluminum edging for a cleaner finish on the ends.

And, I topped off each wall with marble bullnose tiles from Home Depot.

Tip Six – Seal Natural Stone Tile Before Grouting

ALSO, make sure you use a good stone sealer on those marble tiles BEFORE grouting.

It’ll help seal out the grout and any moisture. Marble should be sealed every 6 months. But, don’t worry, it’s super easy. You just wipe on stone sealer with a rag.

Tip Seven – Get Those Shower Drain Tiles Right

The last tip to cut and install mosaic marble tile is about the shower drain.

I completely, cut and dry fit this mosaic tile on my shower floor before I mixed the mortar to install it. You can see the circle in the center marks my shower drain cuts.

Again, I laid the tile out then marked the drain cut out with my grease pencil. Then I cut those tiles off the mosaic mesh backing with a box knife before cutting.

I also had to raise the drain to the correct level before I could start tiling. When the plumbers poured the mud floor they did a great job sloping everything to the drain, but the drain was too low for my tile.

Luckily, this drain style is easy to adjust, but needs to be done before tiling. That grey piece on top screws into the white pipe you see inside.

Once I loosened the grey piece from the mud floor, I could unscrew it enough to raise it to the correct level. You don’t want any water sitting in that grout around the drain. So, set it just a hair below the grout level.
