Porcelain bathroom floor tiles - a buying guide

Porcelain bathroom floor tiles are hygienic, easy to clean, and tiles are available in different slip ratings so if you are looking for a little extra grip, you can find it.  Porcelain bathroom floor tiles can also mimic other materials that are not perhaps suitable for bathrooms such as natural wood and does so cost effectively. Bathroom floors need to be waterproof. Water can splash from sinks, steam from showers can mist surfaces and water is likely to find its way onto floors no matter how carefully you step from the bath.

 

To be called porcelain, a tile must have a water absorption rate of less than 0.5%. That makes porcelain pretty much waterproof – in fact, porcelain can be used outside it is so hardwearing and tough. So porcelain bathroom floor tiles are perfect for busy bathrooms. We should add if you are looking to create a wetroom then you will still need to ‘tank’ the shower area etc to ensure it is full waterproofed – whilst porcelain has a low water absorption rate you will still need to grout in between the tiles. However, porcelain as a material is the ideal canvas for bathrooms delivering both durability and design in spades. So including design, what are the key considerations when choosing porcelain bathroom floor tiles?

Tile finish

As tile technology continually improves, porcelain design has also come on leaps and bounds. Gone are the days when a marble tile had 2 graphics per collection and therefore repeated across large spaces. Today, some porcelain collections may boast 20, 30 or even 40 different designs per tile. It’s not just the differing designs, technology is also pushing the boundaries of realism with porcelains now mimicking other materials to the highest degree. This is about pattern and tile finish aligning, so gone are completely flat wooden planks and in are wood effect porcelain planks that have a slightly undulating surface and where the surface texture and pattern align to echo the knots and gnarls of really wood. So much so, it is hard to tell the difference! These really are premium floor tiles for stunning bathroom design. Now you really can have wood in the bathroom and what’s more, all this needs is a quick wipe down with a mop and warm water to keep it in tip top condition!

Tile size & format

The size of tile you choose can have a dramatic impact on your overall design. That is mainly due to grout lines. For bathrooms, which tend to be some of the smallest rooms in our homes, size of tile is a key consideration. Porcelain bathroom floor tiles come in a range of sizes and generally you will find the same design of tile available in 3 or 4 different sizings from smaller format to larger options. The larger the tile, the less grout lines.  Sometimes it is tempting to think small space, so opt for smaller tiles. But opting for a larger format tile with fewer grout lines can actually make your space feel larger. There are a few things to consider if you are loving the large format option so read on!

 

Tiles come in all shapes and sizes with square and rectangular the obvious front runners. <With square, there are less things to consider regards installation. Whereas with rectangular tiles, particularly for floors you will want to consider whether you stack or brick bond tiles into a pattern. You will also want to think about which direction you run the tiles in. It is also worth noting that if you do go rectangular, then for tiles with a length longer than 600mm you don’t want your overlap to be more than 33%. Even the best porcelain will have a very slight curve for longer length tiles and offsetting by no more than 1/3 of the tile length will help reduce any lippage so where your porcelain bathroom floor tiles meet they are flat.

 

Every bathroom and every bathroom project is of course, different and we would always recommend employing the services of an expert regards your tile installation. It is always worth checking with your installer before you go ahead and purchase your tiles to ensure they are suitable and to consider things like room access, the substrate you are adhering to aswell as the complexity of the room ie are there lots of cuts, corners etc. If access is restricted into the bathroom or there are tight corners and stairways then it may be a squeeze trying to manoeuvre extra large porcelain tiles – those 1200 x 1200mm giant tiles are also very heavy and the recommendation is having more than one person to lift. It can also be tricky trying to lay really large formats in small spaces so always speak with your installer before committing to a tile size. Floors are likely to be more flexible in a bathroom due to their make up (unlike ground floors which may be concrete) so again, check with your installer if you are wanting to go for extra large porcelain tiles. Some of these larger formats can be thinner (to make them lighter for handling purposes) so you may find them at 6mm or 8mm thicknesses. Essentially the porcelain tile will be fine as long as it is installed correctly. But that’s not to say you can’t have that stunning large format tile you always dreamed off to create the wow factor.  Just check it out first!

 

Tile installation & wastage

This is something we get asked lots! Bathrooms are one of the tricker spaces regards wastage. For a tile size of around 600 x 600mm it is usually 10% and that rises to around 20% for larger formats.  However, you may get away with less if your room is pretty straightforward. But if there are lots of angles and cuts you may need more. If you are able to plan out the layout with your tiler this can help. You may be able to work out the number of tiles you actually need and then add on a specific number of spare tiles instead of a percentage. Whichever you do, it is important to order enough tiles for your project in one go. Chance are you won’t be able to buy from the same batch if you don’t.

Tile grout

The secret to a seamless canvas is to opt for porcelain bathroom floor tiles that are pretty uniform in design. Concretes and cements are brilliant options. They have a little something going on from a design perspective, so they aren’t too flat, but they also allow you to match a similar colour grout so the floor can look as seamless as possible.

Contrast this with say a marble where you have veining that is running across the tile and you maybe have a few different colours to consider. The background may be predominantly white so you may want to match to the background or pick a colour in the tile. Or, you could go mid or dark grey and make a feature of the grout lines. Whatever you decide test first before committing to the whole area. 

Tile Finish

Porcelain bathroom floor tiles are available in a host of different finishes and those finishes will have a slip rating. Slip ratings help with understanding how a tile will perform in wet and dry areas so it’s important to consider these when deciding on your tiles especially if you are installing a wet room. Check out of Guide to Slip Ratings for more info! You can find it in the footer of our home page.
