The width of the doorway in the bathroom. Which one and why?

When starting to repair wall panels and laying flooring, it is important to understand that the width of the doorway in the bathroom must correspond to the size of the purchased door. One way or another, you still have to install partitions, so it’s better to take care of expanding or narrowing the opening in advance so that you don’t start repairs again later.

Doorway in the bathroom: dimensions and standards

In order not to face the problem of refining the wall decoration or ordering a non-standard room door during repairs, it is important to determine what width of the door frame to the bathroom you need. What else you should pay attention to:

1. measure the width of your opening in order to know which door frame you need in the bathroom;
2. choose a door of the right size from a large assortment offered by manufacturers;
3. determine whether platbands are needed in the bathroom. Many owners prefer to put platbands so that the door looks more finished and pleases with its aesthetics. Despite fears that the platbands will swell, get wet and retain moisture, this form of decoration should not be abandoned. If you don’t arrange a “sauna” in your soul every day, then nothing bad will happen to the architraves. But the platbands on the door in the bathroom will help hide some of the finishing errors. The gaps in the bathroom door frame will also be hidden if the bathroom door trim is exactly the right size. But you can choose any shade: manufacturers offer both color solutions to match the box and door leaf, and options that contrast in shades.

The main standard of the presented products meets the following parameters:

• height 200 cm.
• width 60, 70, 80 cm.

Many product suppliers set the standard for 55cm width with 190cm height, with bathroom frame thickness ranging from 15mm to 40mm.

Important! If the accuracy of the calculations is not observed, it may turn out that it does not fit into the opening of a wall that has a load-bearing function. There will be a need for expansion, which in some cases is completely impossible due to the design of the partition. An opening made of drywall is also not always available for enlargement: the metal profile cannot be moved.

An affordable solution in this case would be to install a custom-made door frame in the bathroom, and these are additional financial and time costs. Increasing the size is not always possible, but reducing the height of the bathroom door opening is a more acceptable option if you made a little mistake with the dimensions.

Calculating the size of the opening: what you need to know

1. You need measurements of all the parameters of the door block that you want to install.
2. Door frame options.
3. The presence of a threshold.
4. Casing sizes.

When installing the opening, it is necessary to take into account not only the dimensions of the structures, but also the mounting gaps.

Important! Do not forget that the width and height of the opening are not the only parameters; the bathroom and toilet box must take into account the thickness of the opening. A standard typical house corresponds to 75 mm, which must be taken into account when preparing the installation and purchasing or ordering a structure.

And the last issue that needs to be resolved: the acquisition of slopes, extensions. In the case when the expansion of the box is necessary or it needs to be cut along (the wall is much thinner), the installation of platbands will become impossible without extensions. And practical platbands in the bathroom are often absolutely necessary. You can see a photo of the doors to the bathroom with platbands below.

Important! The best doorway is such an opening, the height and width of which exceeds the door leaf by 8 cm, and the thickness of the walls is 7.5 cm!
