Narrow Bathroom Designs

Narrow bathroom designs can be tricky to get right. Within a confined, narrow bathroom you need to somehow design-in a shower, vanity, toilet and mirror – and that’s just the start!

Sometimes you’ll have a room that requires you to enter from one end or you can place a doorway in the middle of one of the longer walls.

Remember, good narrow bathroom designs will also require you to optimise light, space, storage and functionality.

With all this in mind, below are 18 expert tips for narrow bathroom designs:

  • Tip 1. Most often your shower or bath will run side to side at one end of the bathroom to efficiently optimise the space.
  • Tip 2. A shower over bath will deliver the greatest versatility if kids are going to use the bathroom or you like to soak in the bath

  • Tip 3. In wall toilet cisterns are a must in narrow bathroom designs. They cost about twice the price of a regular toilet but saving that little extra can mean a lot. In this image above you'll also notice that the space allowed for toilet width is far less due to it's positioning forward of the shower recess
  • Tip 4.The smallest you can go with a shower is about 80cm from side to side. They can be done smaller but they’ll be noticeably small.
  • Tip 5. A shower with a bi-fold or slider door will save space. 
  • Tip 6. Larger format tiles will make narrow bathroom designs appear visually larger.

  • Tip 7. Maintain consistent tile styles and colour to optimise the visual space.

  • Tip 9. Minimalist, clean, neutral lines and colours will optimise your visual space.
