How to lay bathroom wall tiles – experiment with new patterns and textures

Industry experts share how to achieve that professional finish

Tiles are the natural choice for decorating bathroom walls. Yet while they may be practical and easy to clean, they also offer endless design opportunities.

Laying new wall tiles in a bathroom is one of the best ways to update this space. However, depending on how much of the wall you choose to tile, and factoring in a 10 percent surplus incase of breakages, a new set of tiles can become expensive.

If you are working within a budget, you can cut costs by laying the tiles yourself. To help you achieve a professional finish, we’ve persuaded industry experts to share their advice on how to lay bathroom wall tiles.

WHAT SURFACE IS NEEDED FOR WALL TILES?

Before tiling you need to ensure that your bathroom walls are smooth, waterproof and strong enough to support your chosen tiles.

‘If your surface is uneven you can overboard it with a tile backer board which will provide an even surface to make fitting much easier,’ explainsAmanda Telford, CTD Tiles Marketing Manager. ‘Whatever surface you are tiling on to needs to be load bearing and able to hold the weight of the tiles, adhesive and grout combined.'

THE TOOLS YOU'LL NEED

You will need a few specialist tools to lay bathroom wall tiles. For cutting the tile you will need a metal ruler, tile scourer, tile nipper and fine sandpaper. For the grout you will need a grout float and grout finishing tool.

For the adhesive you will need a bucket, drill with a mixing paddle attachment and a tile adhesive spreader. To lay the tiles you will also need a pencil, tape measure 5mm floor tile spacer, long spirit level, a sponge and timber batten and fixings.

STEP 1 - PREPARE THE SURFACE

Before beginning to tile make sure the wall has been sanded down, cleaned and sealed.

If the walls need to be strengthened, this is also the time to install a backerboard according to the manufacturer's instructions.

STEP 2 – MIX UP THE TILES TO AVOID COLOR DISCREPANCIES

Plan how you want them to look. Lay them out of the floor, to test out any patterns. Avoid any stark colour discrepancies by mixing tiles from several boxes, this will help achieve a blend of colour, texture and pattern.

STEP 3 – WORK OUT YOUR STARTING POINT

Make a tile gage using a wooden batten. Place it on the floor next to a row of tiles, with spacers in between and mark each tile on the wooden batten.

Measuring the wall horizontally find the midpoint and align the first line on the tile gage with it. Move the gage to the left mark by mark, until the wooden batten is close to the corner of the wall. Mark on the wall where the last tile would end, and using a spirit level draw a line to the ceiling.

Repeat the entire process again vertically, before screwing wooden battens into place over the lines – your starting point is the corner where the battens meet.

STEP 4 – LAY THE FULL TILES

From your starting point, use a notched spreader to cover part of the wall in adhesive. Apply the tile firmly with a slight twisting action. Repeat with the rest of the tiles, inserting spacers between each one.

Use the wooden batten and spirit level to ensure the tiles are straight and level. When the adhesive has completely dried remove the wooden battens.

STEP 5 – CUT AND LAY THE REMAINING TILES

Measure the gap between the last full tile and the wall. Accounting for the spacer, mark the measurement on a tile and scour a line, before snapping the tile. Repeat for the rest of the tiles.

Starting from the bottom of the main design, lay the cut tiles in the same ways as the full tiles.

STEP 6 – GROUTING

Once the adhesive has completely dried, mix up the grout and use a grout float to work it into the joins between the tiles. For a neat finish, use a grout finishing tool to go over the joins.

HOW DO I PLAN A WALL TILE LAYOUT?

Wall tiles are available in a whole host of shapes, sizes, colours and finishes, which can be arranged in a number of different ways, so take time to research the look you’d like to achieve. It is also important to consider how the size of the bathroom, lighting and tiles will all work together.

When planning your wall tile layouts, make sure you think about the size of your bathroom. Yousef Mansuri, Head of Design at C.P. Hart, explains, ‘If it’s a compact space, we recommend large format tiles. This is because less grout lines give the walls more continuity, creating the illusion of a larger space.’

WHAT'S THE BEST MATERIAL FOR BATHROOM WALL TILES?

‘Typically, porcelain tiles are popular for bathroom walls in both small and larger formats as they’re available in so many stylishtrends and also easy to wipe clean and maintain in years to come,’ explains Harriet Goodacre, Tile Consultant at Topps Tiles.

Porcelain is a practical tile as it is nearly waterproof, and suited to the humidity and condensation of a bathroom.

WHEN TILING A BATHROOM WALL, WHERE DO YOU START?

Before tiling a bathroom wall you need to work out your start point as shown above in the step-by-step. The reason for this is to ensure that as many full tiles as possible are used.

When working out the starting point, if the space in the corner is less than half a tile, move the tile gage half a tile’s width to the right of the centre point. This is to allow space for a larger cut tile to be fitted, creating a cleaner finished look.

HOW FAR UP THE WALL SHOULD I TILE?

In a bathroom you should ideally tile any areas where water is to avoid damp areas. Aside from that practical detail, how far up the wall you tile is a personal preference.

‘In shower enclosures we recommend tiling to the top of the wall,’ suggestsHannah Guilbert, Product Marketing Manager at Original Style.‘For the rest of the space, tiling at half height is both pleasing on the eye and a good way to ensure your walls are protected from sink, bath and shower splashes.’
