Bathrooms

Focus on: Bathroom Fans

If you are considering a bathroom upgrade, it is easy to focus on the “fun” elements: colour schemes, shower types, taps and light fittings, but the functional elements can often be left as an afterthought. One of these “afterthoughts” is ventilation. In this piece, we will explain why ventilation is so important – especially in a bathroom – and give you tips for fitting the right bathroom fan.

If you are considering a bathroom upgrade, it is easy to focus on the “fun” elements: colour schemes, shower types, taps and light fittings, but the functional elements can often be left as an afterthought. One of these “afterthoughts” is ventilation. In this piece, we will explain why ventilation is so important – especially in a bathroom – and give you tips for fitting the right bathroom fan.

Why are bathroom fans so important?

It is fairly obvious that a bathroom fan will help you to get rid of the steam in your bathroom and improve the overall air quality. But it’s more than just helping you to look in the mirror. By making sure that you have proper ventilation in your bathroom, you can avoid mould and damp in the bathroom itself, but you can also reduce the overall humidity in your home, reducing condensation and helping to prevent the buildup of mildew as well as removing bathroom smells.

Do you need to install a fan?

The best way to see if you need to install a new bathroom fan is to use a hygrometer. You can buy these as standalone gadgets or integrated with a dehumidifier. If your humidity levels are over 50%, then you probably need to get a new fan as high humidity isn’t just bad for your house, it can exacerbate health problems such as asthma and other respiratory illnesses. Other signs that you need a new fan are peeling paint and other signs of damp, such as excessive condensation, mould or mildew.

Fitting a new fan

If you are hoping to install the fan yourself, there are a few key elements to remember:

  1. Check that you are buying the right type and size of fan for your bathroom. This includes making sure that your fan reaches the right electrical specifications.
  2. Choose your location carefully. If you have a fan installed already, make sure that it is in the best position before switching it out for a new fan.
  3. Make a list of preparation activities that you need to do to prepare for the fan fitting e.g. drilling a bigger hole, and make sure that you do it safely and properly.
  4. Be sure to switch off the power to your bathroom at the fuse box before you do any work.

Water and electricity most certainly don’t mix, so if you are unsure of what you are doing, contact a bathroom specialist or electrician to give you a quote for fan installation. The other advantage of getting a professional in is that they will be able to advise the most appropriate fan for you to use, as well as one that fits in an existing space, if you have one.

  • Do I need a plumber or a bathroom fitter to install a new bathroom?

    For a simple swap - same bath, toilet, or basin in the same spot - a plumber can usually handle it. For a full renovation with layout changes, tiling, and proper waterproofing, a bathroom fitter is the better choice. Many larger jobs need both, or a fitter who subcontracts the plumbing. Be upfront about what you want when you're getting quotes - it makes a difference.

  • What are the most popular bathroom design trends right now?

    Walk-in showers with frameless glass are still the most popular choice - they look great and make the space feel bigger. Wall-hung toilets and basins are increasingly common for the clean look and easier cleaning underneath. Brushed brass and matte black are the tap finishes people are going for right now, largely replacing chrome. Warmer tones - stone, clay, warm whites - have pushed out the all-grey bathroom of the last decade. And underfloor heating and digital showers are increasingly being planned in from the start rather than added as an afterthought.

  • What is the difference between a wet room and a shower room?

    A shower room has a shower enclosure - the shower is contained within its own space. A wet room is different: the whole floor is waterproofed and slopes to a drain, with no enclosure at all. Wet rooms look clean and minimal and work really well for people with limited mobility. The catch is they need far more thorough waterproofing during installation - any gaps and you'll get water getting into the structure. Using a professional is an absolute must!

  • Do bathroom renovations require Building Regulations approval?

    A like-for-like replacement generally doesn't. But if you're moving a soil pipe, adding new electrical circuits, or making structural changes, it might. The one constant: any electrical work in a bathroom has to comply with Part P, regardless of how small the job is. If you're unsure, your installer or local building control team can tell you what's needed before you commit.

  • How long does it take to fit a new bathroom?

    A full installation in an average bathroom typically takes five to ten working days, depending on how complex the layout is and how much tiling's involved. A straight swap with no layout changes can often be done in two to three days. Plan for some disruption either way, and make sure you've got access to another bathroom while the work's on.

  • Can I install a walk-in shower myself or do I need a professional?

    The enclosure and screen? Potentially DIY-able if you're confident. But the plumbing and electrical side - no. Electrical work in bathrooms falls under Part P regulations with strict rules around anything near water. Waterproofing is also something people tend to underestimate - get it wrong and you're looking at expensive water damage down the line. For a full walk-in shower installation, get a professional in.
