One of our best decisions with our extension was to swap out the Velux window plans for a Solatube Sun Tunnel. The utility room is in the middle of the extension, my son’s bedroom at the front and the kitchen at the back. This means there isn’t any natural light coming into this room as we didn’t want windows on the side of the house.

When we had our extension drawn up the architect put in two Velux windows in the kitchen and one in the utility room. I had always been hesitant about this for security reasons, but also as the neighbour’s house is set back alongside us they would constantly be able to see down into the rooms. But my concerns were squashed along the way and we went with it….until the building was built and the roof was going on!! 

I knew straight away that the Velux window options weren’t a good idea, I could see this big open hole in the roof and when I stood under it I could see straight through to my neighbour’s window… keep in mind I was having a shower and toilet in my utility room

This photo is with the Velux gap in the roof and from one of my neighbour’s window! I have more neighbours along to the right as well so they would all see in at various angles. 

Why didn’t I just go for blinds, or special glass………

  • The ceiling in the utility room is vaulted so gets pretty high, I wasn’t going to open and close the blinds every time someone goes in. 
  • I couldn’t guarantee that with the lights on the special type of one-way glass, or frosted glass wasn’t just going to become see-through as soon as the lights come on! 
  • If we wanted it for ventilation, I was then worried it would get left open and then becomes a security issue, so will end up just being left shut. We have an extractor fan installed in this room for ventilation. 

So with all my reasons for a Velux squashed and no big positives I looked into a sun tunnel for our utility room

Why A Solatube Sun Tunnel 

I decided to purchase a Solatube sun tunnel due to many reasons. You can pick up sun tunnels from DIY stores and online, but after I did some research into them I found it would be much better to purchase a Solatube one. 

Solatube is a company that specialises in this type of product. They make various versions of these types of sun tunnels for different private and commercial areas. They’ve produced a product that is dedicated to bringing light into dark rooms, so naturally, I felt their product would produce the best natural light into this room. 

After looking into a Solatube sun tunnel more, I love the sound of their product. That actual sun tunnel section has been designed to bounce off the sunshine in the correct way to nose the sun as it comes down the tube. It’s made from a metal that reflects the light as it goes down the sun tunnel. The DIY versions had white plastic sun tunnels so you lose the sunshine as it comes down the sun tunnel. 

Also, the DIY version had a concertina sun tunnel which traps the sunshine in the gaps as it travels down the sun tunnel, meaning less sun gets into the room. I was trying to get a product that offers me the most sunshine in the room as possible! 

Get The Correct Size and Shape 

Solatube has many different shapes, designs and extensions for the Solatube system, so you want to check with them which one works for you. I contacted them as I wanted to make sure I was able to use this Solatube system in a vaulted ceiling as it means you don’t have much roof gap between the ceiling area and the roof dome. They were very helpful and assured me the one I was ordering would be suitable. 

The Solatub sun tunnel has angled tubes for flat ceilings and also extensions to make them a longer sun tunnel section, up to 9 metres! There is also a reflective strip on the outside part of the sun tunnel that you can position to get the most sunshine reflecting into the room. 


You have a few options of finishes for your Solatube sun tunnel, from round designs, square and the type of domes on the top. You can pick from various different finishes inside the house as well. 

We have the 35cm round sun tunnel with the frosted diffuser which means I cannot see up into the sun tunnel

How Well Does The Solatube Sun Tunnel Work? 


I am so over the moon with the Solatube Sun Tunnel, this room has no natural light in at all and you would have to turn the light on every time you went in there to be able to see anything. In the pictures below, I have no lights on at all. All the light coming through is natural light from the Solatube Sun Tunnel, it’s even too bright for my pictures!! 

I wouldn’t hesitate to get another Solatube Sun Tunnel for a room that needs light with no windows, it solves the problems of security, no windows, privacy and you don’t compromise on the amount of light. 

When we were allowed people in the house, people would think there was a light left on in the room!!!

  1. Hi Steph,
    Just wanted to thank you for writing such a great blog on the Solatube. These things always sound so much more convincing when a genuine customer writes about them. I’ve linked to your blog from my Facebook page – hope that’s OK with you. If you need any more information about Solatubes and sun tunnels please let me know – I would be delighted to help. Thank you once again.

    • That’s ok, thank you very much. We are so pleased with it and everyone is amazed by how much light floods in!

  2. There’s a shop on our street that has one of these. My 6 yr old was really interested to find out what it is and how it works (before lockdown, he asked quizzed the shop assistant on it when he was in there with me one time).

    • Ahh how sweet! It’s a fantastic idea and yes I can see why he was interested in it!

  3. Oh wow, what an incredible renovation, I am with you and see why you went for the solatube instead of the Velux windows

  4. I’ve never heard of a Solatube Sun Tunnel before, but it is genius! We would have the problem of getting natural light into rooms if we had an extension and this could very well be the answer we’ve been looking for, so thank you 🙂

    • Ah glad it was helpful for you, it solves that problem doesn’t it! I wasn’t convinced we would get enough light through here but it’s fab!

  5. This is such a good feature for a small room with no windows – it really makes such a difference to the lighting. Your bathroom looks gorgeous!

  6. Oh wow! I have never heard of this but what a great idea! We could do with one of these in our utility room. Although I now just want your utility room, ours is rubbish compared to yours!! Lol

  7. This is fab. I had never really thought about solar tubes before. I grew up in a home with no window in the bathroom, this would have been great!
