Preparation for tiling

Once you have the tools together, now you can get started by preparing your bathroom to be tiled. This stage ensures the most accurate measurements possible and should start by removing all furniture, bins, bath mats, storage towers, picture frames or any other portable fixture that isn’t fixed to the floor. Doing this gives you complete and unobstructed access to all areas of your bathroom. Next, it’s wise to clean the entire area to remove any particles or pieces of dirt that might disrupt any measurements.

You will likely have already considered the desired size of your tiles before you reach this point, but this is the stage where you need to confirm this information. Consider the needs of your space and select tiles accordingly, for example, smaller tiles offer more versatility for colourful creativity whereas larger tiles open the space out and are also easier to clean thanks to their smaller number of grout lines. If you’re wondering what size tiles you should buy for your small bathroom, or want advice on how to design your space, contact us and our expert team would be happy to lend a helping hand.

How to measure your floor for bathroom tiles

Right, let’s get down to business. Unfortunately, measuring a bathroom floor for tile installation is no easy task thanks to how different each room is shaped from one house to the next. While some bathrooms will be tiny yet have no existing fixtures, others might be large and awkwardly shaped with immovable bathrooms, sinks and more to contend with. Let’s start by outlining how to measure empty rectangular-shaped bathrooms for floor tiles, aka a tiler’s dream job.

  1. Measure the length of the shorter wall and record the number in cms. Make sure the tape measure is placed as flat to the wall as possible for the most accurate measurements.
  2. Do the same with the length of the longer wall and record the number in cms.
  3. To work out the total area of the room simply multiply the calculations of both walls. We now need to convert this figure from cm2 to metres squared, so divide the total by 10,000 to find the total area of your space in m2.
  4. Accidents happen, so to cover for cutting mistakes and breakages, add in a wastage allowance of 10% of the total area calculation.
  5. Once you have these measurements, it can be useful to create a bird’s eye view sketch of the space, allowing you to better plan the design of your bathroom going forward.

How to measure your walls for bathroom tiles

Measuring the walls of your bathroom for tiles is very similar to measuring your floor, however, the process is often complicated by the presence of windows, extractor fans and more that need to be accounted for. To discover the area of a bathroom wall, abide by the following steps so that your wall tiles will be fitted as efficiently as possible:

  1. Measure the height of the wall and record the number in cms. As outlined above, make sure the tape measure is placed as flat to the wall as possible for the most accurate measurements.
  2. Measure the length of the wall and record the number in cms.
  3. Multiply both calculations together to find the total area of your wall in cm2. Convert to m2 by dividing this number by 10,000.
  4. Next, measure any obstructions like windows using the same method outlined in steps 1, 2 and 3.
  5. Subtract the m2 measurements of any obstructions from the total area of the wall.
  6. Work out 10% of this total calculation and add it on as wastage allowance. You now have the total area of your wall in m2.
