When my sister and I ran an herbal gift shop we sold a lot of essential oils, items made with essential oils, and accessories to go with essential oils. One, was a pretty ceramic diffuser, that you heated water with a few drops of the essential oil(s), simply from a tea light below. So, recently when I was decorating terracotta pots I got the idea to create a diffuser using a flower-pot. This diy essential oil diffuser was pretty easy to make, and I’ll show you how.

If you are familiar with essential oils then you know that their natural fragrance is beyond compare. In addition, many people believe that they have great healing properties. I am not a medical professional however, and would not begin to claim any medicinal benefits, but I do love the way they smell.

All you need is a terracotta pot and a saucer that fits on the top, a tealight, and a Dremmel tool

The key to getting the diffuser to work is to cut a hole in the side, to let oxygen in, so that tealight stays lit. I did a little research and found some people using hole saws and others using a Dremmel tool. After watching this video from Dremmel, I decided to give it a try.

I did soak the pot in water for about 30 minutes as suggested in the video. On the second one I tried cutting it without soaking, and it took much longer to drill. As you can see, the first pass pretty ragged.

I went back and tried different speeds and worked on smoothing the opening the best I could. I also used a little bit of coarse sand paper to sand the edges. No perfect, but I think this is something that requires a little practice. Still, I was happy with the results.

And yes, they did work. I decided to paint one of them. I used some varnish on the top to protect the paint. Within minutes I could smell bergamot, my favorite oil , drifting throughout the room.

This diy essential oil diffuser is easy to make. For a few dollars you can have your home smelling sweet with the power of essential oils.

  1. Hello!
    Did you use a sealer on the part where tge oil goes?

    • Hi Sue,

      I did put a sealer on the painted one but I do not think it is necessary for the natural one. First of all you will be filling it with water first. Then you add a few drops of essential oil on top of the water. When the water starts to get warm it will diffuse the essential oils into the air.
      Hope that helps,

  2. Love this. Could you tell me if you uses just the essential oil or do you add water and if so how much?
    Thank you

    • Hi Jennifer,
      I fill the saucer with water. Fill it as much as you feel comfortable without having spill over the side.
      Then add a few drops of essential oils. Anywhere from 5-10 drops. You can experiment on what works for you.
      Thanks for stopping by,

    I was told that essential oils and water don’t work well together. Would it be better to use something like almond oil instead of water?

    • Hi Hannah,
      The essential oils sit on top of the water and the candle heats the water which allows the essential oils to diffuse through the air. I’m not expert but when my sister and I owned an herbal gift shop we sold similar clay vessels an the were meant for water with essential oils. I don’t know if oil would work and haven’t tried it. I think oil is better for blending in perfumes and other cosmetics.
      Thanks for stopping by,

    What kind of sealer did you use?

    • Hi Tina,

      I did not use a sealer. I guess you could use one for the pot itself but I didn’t want to use one on the top because I didn’t want it to possibly interfere with the oils.
      Thanks for stopping by,
