What is the ideal size for a toilet?

We may call this place the little corner, but there is no question of making it too cramped. Before’build toilets at home, it is therefore very important to find out about the minimum dimensions to be respected. And if these toilets must be used by a person with a disability, it is better to find out beforehand about the standards imposed on establishments open to the public. Even if they are not mandatory in the private sphere, knowing them makes it possible to create perfect toilets in terms of surface area and layout. Let’s do a check in.

Create a small corner that is spacious and welcoming

Rather than installing toilets where users will barely have room to fit their legs once seated, it is better to have sufficient space. Admittedly, we generally stay there for a short time, but during the day, visits to the toilets are quite regular. This place of comfort must therefore be of irreproachable hygiene of course, if possible benefit from a neat decoration and a trendy layout. But it must also be as comfortable as possible. For this, the ideal is that it be spacious enough.

Finally, if you have the possibility, you have to think about equipping a window the room reserved for the toilets in order to be able to ventilate it properly. Be careful to inquire in this case at the town hall of the commune as to the authorizations to be requested before starting the work. If installing a window is not possible, a air extractor.

The desirable dimensions so that this piece is accessible et practicemust be able to accommodate:

  • A toilet bowl:

    • Either the classic model with a width of 40 cm and a length of 70 cm,
    • Either wall-hung toilets of 35 x 50 cm or, better, 40 x 60 cm, dimensions to which 20 cm should be added for the frame.
  • A roll holder,
  • A brush and its support,
  • Trash,
  • A sink or a washbasin,
  • A mirror,
  • A small piece of furniture in which you can store the stock of toilet paper, a few hand towels, the essential cleaning products and a descaler, a sponge, wipes and room fragrance.

In some homes, the space available is really very limited so that we are forced to create very small toilets. There is no point in embarking on the work if you cannot find a minimum of 140 cm in length by 100 cm in width.

You have to think that a person who is taller than 180 cm must be able to sit down without knocking their knees against the wall or the door. It must also fully open. It is possible to gain some space ensuring that the toilet door opens outwards and not inward. By the way, in the latter case, it is necessary to provide a room with a length of 200 cm.

When one is not limited by the number of square meters, one can arrange more spacious toilets, which is highly preferable, of the order of 150 x 200 cmi.e. 3 M².

Disabled WC: what is the standard?

The NF P 99-611 standard concerns thelayout of toilets intended for people in wheelchairs. It must be respected by establishments that receive the public. An individual can however draw inspiration from it to fit out easily accessible and comfortable toilets for Persons with Reduced Mobility (PRM). As an indication, the main rules for fitting out a WC for disabled people are as follows.

  • At least 85 cm clearance at door level,
  • Opening the door to the outside,
  • Dimensions of the room of 150 x 210 cm minimum,
  • Leave room for maneuver between the door and the toilet bowl. Its diameter must be at least 150 cm,
  • Install a grab bar between 70 and 80 cm from the ground, on the wall adjoining the toilet bowl,
  • Place the washbasin at a maximum of 130 cm from the ground.

If you are not a DIY pro, it is strongly recommended to request quotes from building professionals through a form on line. These experts know all the relevant standards, and can advise their clients on how to design the perfect toilet, with the ideal dimensions.
