Learn how to tile a bathroom from start to finish

If you have ever wanted to re-tile (or tile) your own bathroom but thought it might be too hard as a DIY job – think again! Learning how to tile a bathroom is actually far less daunting than you may realise.

There are many reasons why you may be considering this job. Perhaps you are renovating, building a new home, or your old bathroom just needs a refresh? Whichever it is, learning how to do things yourself gives you complete control over your bathroom’s new look.

The key is preparation and a little bit of practice for your tiling technique. To help, we’ve laid out some handy tips to make sure you stay on the right track with this step-by-step guide. Keep reading to learn how to become a tiling pro! 

Choosing your bathroom tiles before you begin

Before you work through how to tile a bathroom, you’ll need to consider the room’s size and tile type. If you have small bathrooms, you’ll want to avoid large bathroom tiles, as they will create an even smaller feel. From a cleaning point-of-view however, the bigger, the better.

The best options for a bathroom are either porcelain or ceramic (the most affordable tiling choices), with porcelain being more hardwearing than ceramic. For the bathroom wall, you’ll want to find a robust tile that can handle a lot of wear. 

If you are after natural stone, you may need to give the DIY installation a miss, especially if you are a first-timer. Natural stone is porous and absorbent and will need sealing a lot more regularly. If you are short on time, pick a tile that requires less upkeep.

Calculating how many tiles you need

To ensure you do not waste money, you’ll want to figure out how many tiles you require for the whole project before purchasing. Opt for an online calculator that can help you to work out your measurements and the number of tiles you will need. Always double-check your measurements and buy at least 10% more tiles than you think you will need to account for wastage and breakage. 

Having some spares on hand is always a good idea for down the track, in case your style is no longer available in a few years when you may need to replace a broken tile.

How to tile a bathroom: A step-by-step guide

Step 1: Preparation

Before you start, you need to prepare your surfaces, ensuring a smooth base. This is the key to a professional-looking result. It’s better to take the time before you begin, as fixing mistakes after tiling a bathroom is expensive. 

The goal is your bathroom is waterproof, stable and smooth. Get rid of any old adhesive, paint, or wallpaper then wash the walls with sugar soap to remove the dirt and grease.

Step 2: Map out your tile plan with a gauge stick

Create your own gauge stick by taking a length of wood that has the size of your tiles marked along with it. This will help to space your tiles correctly. Simply take a tile, align it horizontally against the stick and mark the end of the tile on the stick all way along until you run out of space. It is essential that you include room for a tile spacer in your measurements. Turn the tile vertically, and repeat on a new stick. 

Once that is ready, use a spirit level to find the centre point of your wall, and mark a line vertically across it. This will be the guide point. Take your gauge stick, place it at one end of the wall along the line, and mark each tile’s guidelines on the stick.

This should now give you an idea where the tiles will sit on the wall.

Step 3: Laying the tiles

Place a tile against the wall in your starting spot. Some prefer to work from the bottom up; others like to start with the centre of the space and work outwards. Whichever you choose remember to add a tile spacer on the connecting side of the tile. 

When you reach the ends, you will likely need to cut the tiles to size for which you’ll need a tile cutter. Mark where the cut needs to be in pencil on the back of the tile, align the mark with the tile cutter and carefully resize the tile.

It helps to tile in rows and apply the adhesive one row at a time before moving on to the next.

Step 4: Applying waterproof tile adhesive

Always use a waterproof adhesive in the bathroom to avoid mould issues down the track. Most adhesives come pre-mixed, ready for easy application with a notched trowel. Spread the adhesive evenly across the whole area.

When it comes to tiling around a bath or shower, place the adhesive directly onto the tile, but in cases of tiling a wide space like a wall, apply the adhesive directly onto the wall.

Step 5: Mixing the grout

When the adhesive is dry, you can begin to grout your tiles. Place the grout in a clean bucket and add some water. Mix until the grout becomes thick and creamy, let it sit for a few minutes, then apply it to the wall.

Use a trowel to place grout onto the sponge, then work it into the wall via the exposed gaps between each tile. Work on a small section at a time and use a different, clean sponge to wipe excess grout if necessary. Wait for the grout to sink into the surface properly before moving onto the next section, which can take around fifteen minutes. 

When you have finished, sponge down the entire surface and add more grout to any area that that needs it. This should be all you need to do to tile your bathroom! Make sure you leave the area to dry completely before you begin to use it.

Frequently asked questions

Where do you start when tiling a bathroom?

There are two options for where to begin when you are tiling a bathroom. Some people opt to work from the bottom of the wall up; others like to start with the centre of the space and work outwards. In some cases, this will be dictated by the section of the bathroom you are tiling. You have options for walls, but when tiling around corners or small sections of showers and baths it can be best to work with the space. Whichever way you choose remember to add a tile spacer on the connecting side of the tile. 

Can I tile my own bathroom?

Yes! Tiling a bathroom yourself is much easier than many people think. The key is preparation and a little bit of practice. Spend some time choosing the right tiles, measuring the space to understand how many you need and preparing the area.

Take time before you begin to start with a clean smooth surface before tiling as fixing mistakes after you have finished can be expensive.  As long as you do not rush or cut any corners, you should be able to create a professional-look for your new bathroom all by yourself.

What do you put under tile in a bathroom?

It is a good idea to use a waterproof adhesive under the tiles in the bathroom to avoid mould issues down the track. Most adhesives come pre-mixed, ready for easy application with a notched trowel. In cases where you are worried that the weight of the tiles will be too much for the wall, you can use an underlayment of cement board to reinforce the wall and create a better grip for the tiles.
