How to Measure Shower Doors


If your shower doors have seen better days, or you’re simply starting afresh with a new shower enclosure, you might be wondering how to measure up for the correct shower doors. Worry not, as this article takes you through a step-by-step guide to measuring shower doors and how to get the best fit for your needs. Keep reading for more details.

The Importance of Measuring Shower Doors

Ensuring you measure for a new shower door correctly, before purchase, is essential. We always suggest double and even triple-checking your measurements before purchasing a new shower door. Keep reading to find out why.

If you purchase a shower door that’s not correct, or if it’s even slightly off just by millimetres it could cause serious issues with leaks in the future, as well as the door getting stuck or not closing at all.

A leaking shower door is not only annoying and costly to fix, but if left untreated it could also affect other areas of your shower enclosure, leading to a larger leak and unwanted mould and damp issues.

Not only could incorrect measurements lead to a leaky shower door, but they could also be a waste of time and money. The last thing you want is to end up with a shower door that doesn’t fit, as not only will this prevent you from using your shower enclosure, but it could also waste money if you’re not able to return the door.

What Tools Will I Need


Before you start measuring for you new shower doors, ensure you have the following items to hand:

  • Measuring Tape
  • Spirit Level
  • Pen and Paper
  • Calculator
  • Someone to help (to hold one end of the tape measure)

Steps To Measuring Shower Doors


Making sure you measure you’re shower door correctly can make or break that relaxing shower experience you desire. If you’re a few millimetres off with your measurements this could result in your shower door not fitting correctly, leading to potential leaks or not being able to fit the door at all.

Keep reading for detailed step-by-step instructions to get the most accurate measurements of your shower door possible.

  • Firstly, you need to measure the height of your shower door, this is particularly important in homes with low or sloping ceilings. This is also where you might need some help holding the tape measure. The average shower door tends to be around 1800- 2000mm in height. If your measurements are lower than this, it’s best to consult a professional as they may have to source a custom-made door.
  • Measuring the width of the shower door is your next task. It’s best to take this measurement at the top, middle and bottom of the door to ensure it’s the same width. This is a good idea if your walls aren’t completely straight.
  • Once you’ve measured the width, take note of all three widths if they are different. If you are creating a new shower enclosure, you may find the width will dictate the type of shower door you can install. For example, if the space is particularly narrow, a sliding shower door is likely out of the question, but a hinged or bifold door might be more suited.
  • You now need to check if your walls are straight, as this could affect the type of shower door you need. Using a spirit level, again ideally in three places on your wall, top, middle, and bottom.
  • If you are measuring a current shower door rather than an open space, it’s also a good idea to measure the door opening space. This is when you should ask yourself, does your current shower door provide enough space to get in and out and whether it’s obstructing other items such as a vanity unit or toilet?
  • Lastly, it’s a good idea to double or even triple-check your measurements. Once you’re confident with your measurements you can now start browsing shower doors to find the best option for your space and needs.
