Bathrooms in Loft Conversions Guide

Taking the time to create a bespoke bathroom in your loft conversion is a great way to increase the valuation of your home as well as give you a new place to relax, but there are some considerations you should note, such as:

  • Do you have the space?
  • Does your new bathroom conversion need planning permission?
  • Will my gravity-fed water system work?

In this article, we will cover some potential issues you need to account for when designing your bathroom loft conversion.

Is it possible to put a bathroom in an attic?

The short answer is yes! It is entirely possible to fit a bathroom in your attic or loft. Your imagination can only be capped by the size of the space you’re working with.

There may be potential issues with the location of your water tank and pipes, but these can be moved for a fee.

Do you need planning permission to put a bathroom in a loft?

Typically, most loft conversions, such as bathroom loft conversions do not require any planning permission, but it always pays to be safe.


We would recommend bringing in either an architect or some sort of builder to confirm if you would require planning permission or not.


Read our guide on permitted development for more information about loft conversion planning permissions.

Building Regulations regarding your Bathroom Loft Conversion

As stated above, you will typically not require any planning permission to convert your loft to a bathroom, but you should be aware of the current building regulations that may affect you.

One of the most important regulations that you will need to follow is fire safety. If you are completely renovating the room, a fire-safe door would be a great addition to the bathroom conversion to minimise the spread of fire if one ever occurred.

One key regulation that may affect you is if your loft is entered by a retractable staircase or ladder. This will not pass the building regulations standards, as they do not deem them safe in an emergency situation. Installing a fixed set of stairs or spiral staircase would help your home pass building regulations and ensure you’re safe.

More information on the building regulations can be found here.

Party Wall Act

For people who live in a semi-detached or terrace house, you should be aware of the Party Wall etc. Act 1996.

The act is an agreement between you and your neighbours confirming the work you are going to have completed on your property. Even though the work will not be completed in your neighbour’s home, they may still hear/feel the labour of your work, so they need to be notified correctly.

Party Wall documentation can be easily found online and will have to be signed by your neighbours before work can take place.

Plumbing Requirements of a bathroom in a loft conversion

When converting a bathroom into a loft, you have to take into account the additional plumbing requirements you may need. In this section of the article, we will cover some of the most important processes you will need to consider when converting a loft to include a bathroom.

Do you have the Correct Water System?

When your home was first built, the builders and plumbers wouldn’t have planned for a bathroom in the loft, so don’t be surprised if you have to move some things around before the real work starts!

Older properties have a gravity-fed system, where the unit uses gravity to send the water around your home. The issue with these types of systems is that they can’t travel upwards. If you’re planning on installing a shower that is higher than your water system, you will have issues.

We would advise you to see if you could move your current water tank to an area higher than your shower, so you can still keep your gravity-fed system.

If your new shower would be able to access cold water, even if not hot, then you should take advantage of an electric shower that will only heat up the water you require.

If you do not have the space or height for a full shower, you could look into the possibility of creating a wet room. Making a wet room would remove the need of having a lifted shower tray and glass frame, saving you precious space. For more information regarding wet rooms, be sure to call a local plumbing specialist.

Where are your pipes located?

Before planning your dream bathroom loft conversion, you should be aware of the location of your water pipes.

The more pipes that need to be extended or moved means the higher the price of the job. We would advise seeing if you can fit your new bathroom in with minimal pipe changes to keep costs down. A trusted plumber should be able to estimate how much this would cost you.

Keeping your bathroom warm

You may be thinking, “how am I going to stay warm in my cold attic?” Well, there are a few things you can do to make your attic or loft nice and toasty without the fear of mould growth or crazy heating bills.

Insulation

Insulating your bathroom loft is vital to keep valuable heat in, and bills down, but how can you properly insulate your new room?

The Energy Saving Trust states that around 25% of generated heat will be lost through the roof if it is poorly insulated, so it pays to be aware of the quality of your insulation.

Attics that were previously used as a cold loft, should have all previously installed floor insulation removed, as heat in the house now wants to reach your attic. The next step is insulating your roof, chimney, and/or walls.

If your attic contains stud walls that are going to be covered in the conversion, we would advise you to fill this empty space with foam insulation to keep heat in your home.

Attic Room Windows

Our PVC roof windows are excellent choices for bathrooms in a loft conversion, as the PVC material is water-resistant, eliminating the worry of moisture affecting the wood.

Underfloor Heating

If you’re struggling for space and do not want to lose any more to large radiators or heated towel rails, underfloor heating may be for you. Ranging from 6 mm to 50 mm, you can choose how ‘thick’ your underfloor heating is to maximise the space you have on offer.

However, you should note that the running costs of underfloor heating is estimated to be around 3 times the price of traditional radiator heating.*

Natural Light & Skylights in your Bathroom Loft Conversion

A challenge some people have when designing their bathroom loft conversion is finding a way to incorporate natural light into their new room. If your roof contains a slope, the addition of a Dakea roof window would be the perfect solution for bringing sunlight into your loft.

Roof windows also increase airflow and heat retention. This will help to prevent moisture in the bathroom causing condensation or mould growth.
