How to measure your bathroom for a DIY Renovation

Before undertaking a DIY renovation, you will need to have a planned layout for the space. To create the most accurate bathroom layout, you will need to measure your space accurately. Miscalculating the measurements can cause undesirable issues further along the renovation process and lead to delays, and possible budget blowouts.

These initial measurements will help create a clear diagram of how much space you have to work with and will help you visualise your planning for the next steps such as choosing the size of your fixtures, the placement of the fixtures, or how many fixtures you can fit in your bathroom.

There may be times when you are planning a renovation on a space you do not have full access to such as a new house you are buying, or an investment property with tenants in it. In this case, you will need to ensure you record all the measurements needed the first time, as it might not be convenient to re-check them later.


What you will need to measure your bathroom:

-          Measuring Tape or Digital Measuring Tool
-          Pen or Pencil
-          Paper or Notebook 


Step 1: Sketch the Room

Drawing a sketch of “a bird’s eye view” of the room or space will help you clearly note down all the measurements. To the best of your ability, try to depict the room as close to scale as possible, if there is a small nook try to sketch it relative to the other walls.

Step 2: Measuring Floor Space

Using your measuring tape, measure the length of each wall then write down each wall. You will need to write down all measurements for the perimeter of the room. In a regular rectangle shaped room, you will take down the 4 walls. When you are dealing with irregular rooms, you will also need to take the measurements for the extra walls that make up the room you are measuring.

To calculate floor space area of a regular sized room, you multiply length x width. To calculate the floor space of an irregular sized room, split up the space into rectangular sections and measure those. Then calculate the floor space of each of the sections and add them together.


Step 3: Ceiling Height & Window Positioning

Measure from floor to ceiling. Make sure you measure each wall because they might not all be the same measurement. If the room as any slopes in the ceiling due to staircases or in attic conversions, you will need to also draw a side elevation view of the wall and note the required dimensions.

 If there are window in the room, you will also need to note down the size of the window and position from floor and from either side of the wall.


Step 4: Door Clearance & Positioning

Measure the width and swing span of the door. This is so you are not creating any obstacles when placing your fittings. You will need to measure its position on the wall to make sure you can still use up the left-over space along the wall for fixtures.

Also, it is important to note whether the door swings in or out.

Step 5: Take note of Existing Fixtures

Record the measurements of existing fixtures such as lighting, plumbing and power outlets. By knowing where these elements are you will be able to more accurately set a budget for the project as you could ask the plumber what the cost of moving elements from one location to another if required.

Also record any fixtures you will not be getting rid of like a bath or toilet. Including them in your measurements will help you accurately decide what else you can fit in this space.

Nowadays most phones have a camera, be sure to take some photos so that you can also reference them later.

Add these measurements to your sketch for extra visualisation of your project.


Other Considerations

Walking room:
Consider how much room you will need to be able to walk freely in your bathroom. If you are renovating a shared family bathroom, you will need ample space for multiple people to be in there at once.

Every bathroom has essential accessories that need to be accounted for when allotting your fixtures to your space. Consider the space needed for a toilet brush holder, toilet roll holder, towel rail etc. There should be at least 60cm clearance in front of a toilet. Make sure to account for cupboard and shower doors need to open without obstruction.
