The layout of your new bathroom could make the room a success or failure. Getting the layout wrong could be a disaster and a very expensive one to fix once everything’s installed. For example, installing a toilet under a sloping ceiling might be a good idea for women, but most men may bang their heads on the wall. These are the details that need to be thought about during the planning stages to make sure that the layout will be functional and practical as well as look beautiful. 

How to design your bathroom layout

You might be struggling to find the perfect bathroom layout that includes everything you want and is practical but stylish. There are so many important decisions to be made and you don’t want to regret any of them later. 

Toilet position

When you’re deciding on a bathroom layout, the first thing you need to think about is the position of the toilet. This is because the toilet needs to be located next to a soil pipe, and having a new one installed or moving the current one can be a big job. Once you’ve decided where the loo is going, the rest of the bathroom can be designed around this. Doing it this way could save you a lot of headaches later.

Fixtures

Once you’ve got the position for your toilet, you need to consider what other fixtures your bathroom will have. First, you need to have a think about your bathroom needs. Is this room going to be a practical family space or do you want to relax and escape from all your worries in there? These two types of bathrooms should look completely different. A practical family bathroom will likely need lots of storage and a walk-in shower, whereas a spa-style space would benefit from a large bath.

You will also need to think about the size and shape of the room. Do you have space for a walk-in shower and a freestanding bath? If not, which of these items would you prefer? Alternatively, you might consider a shower over a bath. You don’t want to stuff lots of large items into a bathroom, as you’ll just make the room feel small and cramped.  

Storage

Finally, once you’ve decided which fixtures you want, you need to think about some more practical features and accessories. Bathrooms frequently lack storage, however they are rooms that really benefit from a place to store towels, medications, toiletries, etc. When you’re planning the design, keep an area free for vanity units, shelving or other forms of storage, such as a laundry basket. You’ll also need to consider where your radiator will go. If your boiler is located in the bathroom, you might want to think about whether you want to move it to another room or keep it there. Moving it could free up some much needed storage space.

By working out these key priorities, you’re making sure that the bathroom will work in the way you want it to. 

How to draw a bathroom floor plan

Once you’ve decided on the above elements, it’s time to draw your bathroom floor plan. Creating a floor plan is a way to confirm that your new bathroom layout and certain technical aspects, such as which way your door opens, will work.

1. Sketch the room

First, draw a rough sketch of the shape of the room. Then include all permanent fixtures and fittings, including doors and windows, pipes, drainage, lighting, charging outlets, radiators and the location of the existing bath, shower, sink and toilet. This may seem a bit excessive, but all of these details could affect the layout later on. At this point, there’s no need to make the diagram to scale.

If you’re planning on making big structural changes to your bathroom, such as knocking out a built-in closet or borrowing space from another room, then make a second diagram including this new layout. 

2. Measure the bathroom

Once you have your diagrams, it’s time to measure the bathroom. You should measure the walls and windows as well as other elements, such as the size of your current bath. As you go, write each measurement down on your diagram next to the element it applies to. 

3. Create a scale drawing

Now you have a rough diagram with some exact measurements of your bathroom. It’s time to create a scale drawing. But don’t worry! This is more straightforward than it sounds.

It’s easiest to do this on a piece of grid paper that has squares a quarter of an inch wide. You can print some off here. Four squares equal one inch. To create a scale drawing, four grid squares could equal one meter. Therefore, if a bathroom wall measures 2.5 metres, your line should cover 10 squares on your grid paper.

You should use this scale to mark out your walls and windows and any major fixtures like your toilet and walk-in shower. If you want to get even more creative, you could cut out a correctly scaled bath, shower, toilet and sink. These features can then be moved around your floor plan to determine the best layout and position for each item. 

How much does it cost to install a new bathroom?

It’s hard to say exactly how much it might cost to have a new bathroom installed. The cost will depend on the extent of the work that’s being done, the size of your bathroom and what fixtures are being installed.

The average cost of a bathroom is around £3,000, depending on the quality of the fixtures you purchase. To have the bathroom installed by a professional plumber would cost around £1,000, but this wouldn’t include the cost of tiling.
