How to Lay Mosaic Tiles in a Shower

If you’ve read the article ‘Why Mosaic Tiles Are the Perfect Bathroom Tile Choice’ which I posted a couple of weeks back, then I’m pretty sure you’ll be considering choosing mosaic tile for your upcoming bathroom renovation.

Today, I’m going to help you further by explaining how you can tile your shower area using mosaic tiles. Hopefully, this guide will come in handy during your bathroom renovation. And once you’re done tiling your shower area, tiling the rest of your bathroom will be a breeze!

So, continue reading this post as I outline a step by step guide to laying mosaic tiles on shower floors.

Step 1: Prime the surface

Before you start tiling your shower floors, you must ensure that your floor surface is in good condition. Your floor surface should be clean and dry and should have a moisture content of less than 5%. To prepare your shower floors, prime the surface using a quality floor primer – Plastinex Red Label is a good product to use for this as it doubles as a tile adhesive. Leave the primer to dry before applying any tile adhesive.

Step 2: Plan the layout of your tiles

Once you’ve primed your shower floor surface, consider the layout of your mosaic tiles. You will need to get your tiles cut around the waste area. Take appropriate measurements and cut your mosaic tiles carefully. Glass mosaics are easier to cut as compared to other types of tiles, so you should face no problems cutting your mosaics into shape.

Step 3: Prepare your tile adhesive

To prepare your tile adhesive, follow the instructions provided by the manufacturer.

If you are working with a powder format adhesive, use a drill to whip the mixture thoroughly – your tile adhesive is ready when there are no pools of water or powder particles present in the mixture. Once you achieve this state, let the adhesive mix slake for about 15 minutes.

Step 4: Apply the tile adhesive to your shower floors

After your tile adhesive is completely prepared, apply the mixture all over your shower floors. You should look to apply a solid bed of 4-6mm of adhesive all across the shower areas. Always work in small areas of a square metre at a time before moving on.

Step 5: Lay the mosaic tiles

As soon as you’ve covered your shower floors with tile adhesive, lay the mosaic tiles immediately. Use a wooden beating block or a rubber grouting float to ensure that you create a level surface. Use a tile spacer to maintain required distance between tile joints. Allow the adhesive to squeeze through tile joints to form grout. If necessary, add more adhesive in low areas to ensure that grouting is even. Clear off any excess adhesive using a damp sponge. Make sure to wipe gently and do not disturb or scratch the glass mosaics.

Step 6: Apply a sealant to the perimeter joints

You’re almost done now! After your mosaic tiles have been laid and grouted, all you need to do is to apply a silicone sealant to the perimeter joints. And, when you’re done, you’ll have a neat looking shower space with brand new mosaic tiles! Follow these same steps to tile other areas of your bathroom.


Laying mosaic tiles on shower floors is easier than you think. First of all, you need to prime and prepare the floor surface for tiling. When you’re done with priming, plan the layout of your tiles and cut your mosaic tiles in shape. Prepare your tile adhesive and let it slake for 15 minutes before spreading it out evenly on your shower floors. Ensure to lay your mosaic tiles immediately after you add tile adhesive to your floors. Make sure that your mosaic tiles are level and that the grouting is proper. To finish the tiling job, add a sealant to the perimeter of the joints.
