Is there a minimum requirement when planning your toilet space? Discover what you need to think about...

Introduction

While bathrooms typically occupy lesser floor space than other rooms, they should not be overlooked. Since you use them multiple times a day, you’d probably want the perfect bathroom layout and a comfortable and pleasant bathroom that you like. Imagine coming back from a long day of work only to dread taking a shower in your master bathroom. Fret not. With careful design and planning, you can turn a small bathroom that is both functional and stylish. There are honestly too many aspects of bathroom design to be covered in just one article such the minimum size of a bathroom or whether you should get floor mounted fixtures. So, this article will be focusing more on the measurements, dimensions, and space needed for the various bathroom accessories for a small bathroom. Let’s get into it.

How much space do you need around a toilet in the UK?

There is no simple and straightforward answer to this as everyone’s bathroom’s layout and personal preferences are different. That said, there are some minimum requirements that you should adhere to regarding how much space you leave between the toilet and other elements to create a more comfortable experience. 

Typical bathroom layout

Before we get into the nitty-gritty details of numbers and statistics, let’s understand how a small bathroom is typically designed. 

For a three-quarter bathroom that has a sink, toilet, and shower, the toilet will usually be found in between the sink and the shower. This is to maximise the space. 

For full bathrooms that comprise a sink, toilet, shower, and bathtub, the toilet is typically installed next to the bathtubs for strategic plumbing purposes. 

Minimum space required

Again, there is no one-size-fits-all answer but there are recommended measurements to serve as basic guidelines.

Assuming that you are designing a three-quarter bathroom, the minimum space required is roughly about 15 square feet. That’s on the lower end. An average-sized bathroom is typically 36 to 40 square feet.

That said, regardless of the size of the bathroom, toilet sizes are generally pretty similar across the market with some minor differences.

Detailed measurements

Seat length

The seat length of the toilet measures from the back of where you sit all the way till it ends at your legs. You get what I mean. 

The standard seat length is 50 cm while smaller models can offer seat lengths of 40 cm and 45 cm as well. If you’re not too concerned with the size of the toilet, you can opt for seats that are shorter in length. You can save some space here. They are, however, less comfortable than the standard-sized toilet seat. If you’re taller than average, then it’s best that you stick to the 50 cm seat length.

Seat width

The standard seat width is 40 cm. The seat width measures from the rim of the seat of one end to the opposite. In other words, the seat width accounts for the area on the seat that you sit on. 

Seat height

The seat height measures from the ground to the top of the toilet seat. The standard seat height varies from 40 cm to 45 cm. Any seat lower than this can make one’s experience uncomfortable and even cause constipation over time since the body is not at an optimal position. On the other hand, any seat higher than this is also uncomfortable and is bad for the user’s back and restricts blood flow in the legs.

These measurements are just a general guide. Ultimately, you’ll want to physically go down to a store to try the different toilet seats out. If you’re going to be using the toilet for a while, do invest in one that is comfortable for you.

Water tank size

  The water tank is stored in the compartment behind the toilet seat. Its width should be roughly the same or slightly longer than the toilet seat width. That’s about 40 cm to 45 cm. The length of the water tank is approximately 25 cm. 

So, answering the question of how much space is needed around a toilet, you’ll want to leave about 38 cm (15 inches) that is measured from the centre of the toilet to the adjacent wall or commodity. Any measurements shorter than that will make the bathroom more cramped than it already is and users might find the experience uncomfortable. 

If your bathroom is bigger, allow a larger gap between the toilet and the adjacent element for greater comfort. You can install other toilet accessories such as a toilet paper holder.

International Residential Code

The International Residential Code (IRC) in the UK has released specific guidelines on toilet installation and measurements to ensure safety and comfort. Besides the suggested guidelines, the IRC also has a strict set of rules and regulations that you have to adhere to regarding the renovations of bathrooms. This includes plumbing, servicing, as well as other codes that have to take note. 

Do check out the guidelines provided by the IRC in greater detail to find out the bathroom and toilet requirements. It’ll help you with your design and planning process if you have some tangible numbers and measurements to work with.

Part M

Part M refers to the building regulations regarding toilets that are designed for people using wheelchairs. 

Depending on the layout of your bathroom, you can opt for either a right-hand or left-hand design. This refers to the free hand that the user will use to pull themselves up from their wheelchairs to the toilet seat. 

Part M regulations state that the grab bar should measure 500 mm from the toilet’s central point. Additionally, there should be free space measuring 1.1 m in front of the toilet and 700 mm around the side of the toilet for increased ease of movement.

Conclusion

What we’ve covered here today about toilets is only the tip of the iceberg. Basically, these are the recommended measurements that you can refer to when deciding on a toilet. The toilet is just one aspect of the bathroom and there are so many more to be covered. Don't worry too much though. You can simply visit your local store and get more professional advice from the experts.
