Getting the measurements right in small bathrooms

Generally speaking, bathrooms tend to be among the smallest rooms in our home, although they also involve a certain degree of complexity, as they feature sanitaryware, furniture and specific spaces allocated for each activity. The tendency is to save on space in order to make other rooms in our home larger, and it is precisely for this reason that bathrooms require a careful aesthetic and ergonomic design to guarantee the necessary degree of comfort, regardless of their size.     

 The minimum space for small bathroom designs  

The body of our bathroom should be at least 2.40 m2, which is approximately 155 cm wide by 155 cm long in the case of a rectangular-shaped space; these proportions allow for the inclusion of all the necessary bathroom elements, including the toilet, wash basin and shower area.  

– Location of the entrance door, a key factor in small bathroom designs   

An important factor for consideration is the door swing – in other words, on opening and closing, it must not knock against the toilet or the wash basin. This means that the door measurements must be in accordance with the size of the bathroom and specific distances. The minimum size for a bathroom door is 60 cm; in the case of small bathrooms, a recommended option is to install a sliding door that will not take up any space inside the bathroom.   

– Basic measurements for the shower area

For reasons of comfort, the shower area should not measure less than 70 cm x 70 cm to guarantee freedom of movement inside. Ideally, the shower base should be rectangular so that it can be aligned on one side and seen as a single element. The shower access should measure at least 60 cm. There should be a free space of 60 cm x 60 cm between the shower and the bathroom door to make access easy, although this space can be reduced to 50 cm x 50 cm if we opt for a sliding door.    

– Toilet size for comfortable use  

The minimum free space required for a toilet is 70 cm x 120 cm as seen from the top; if there is another adjacent element a minimum space of 15 cm must be left and in the case of a side wall, at least 20 cm.  

In the case of small bathrooms, the best option is a compact wall hung model, which will make the space appear larger and make cleaning easy.  

– Furniture proportions in small bathrooms 

When it comes to shapes and sizes, there are various options. In the case of small bathrooms, the minimum size for one piece wash basins is a depth of 35 – 38 cm in reduced spaces, compared with 48 – 50 cm for standard measurements, and a width of 60 cm.  

An important aspect for consideration is the installation height: wash basins should be at a height of 80 – 90 cm from the floor. 

If there is sufficient space and you would like to install a double washbasin, then there should be a central separation of between 60 and 90 cm.  

– Minimum measurements for installing accessories

The toilet roll holder should be positioned at least 60 cm from the head of the toilet and around 76 cm off the floor to make it easy to use from a seated position.

The towel rail, soap dish and toothbrush holder should be at a minimum height of 120 cm from the floor, to make them accessible for children as well as adults.  

So now you have all the basics regarding bathroom design, so that your bathroom construction or renewal project will comply with all the standards of comfort necessary for this much-used space.
