Household appliances sometimes categorically refuse to “fit” into the interior, and the owners have to rack their brains to hide them.
In fact, there are at least 5 such examples that are not only practical, but also beautiful and convenient.
So, where to hide the washing machine.
The kitchen is often larger than the bathroom, unless it is a Khrushchev-era apartment. In this case, you can safely connect the washing machine in the kitchen, installing it under the countertop, hiding it from human eyes with facades.
The problem in the bathroom can be solved in a similar way. Modern building materials and technologies allow not only to put the machine in a cabinet or under the sink, but even to hang it on the wall.
This is the most common option for a hopeless situation that arises in a small apartment.
If the bathroom is combined or simply spacious, then no one will be bothered by household appliances standing separately in it.
It will be more convenient for home owners to provide a laundry room. Then the problem is solved by itself, because here the household appliances are already part of the interior.
