The Geberit concealed frame is a metal frame with a built-in concealed cistern, which is mounted inside lightweight walls or leaned against them, and then covered with tiles. In this way, it becomes invisible and at the same time allows for safe and durable installation of bathroom fittings. This solution is very practical and aesthetic, which is why it is very popular. But how to choose the best model? We give you a hint.
Which model of recessed frame should I choose?
The choice of an appropriate concealed frame depends on several important aspects:
- The most important question to ask yourself when purchasing a concealed frame is the type of construction. Heavy-duty models require carving a recess in the wall and, after installation, bricking the frame inside. However, in light construction, it is enough to attach the frame to the wall and then cover it with tiles or panels.
- Then, you need to determine the dimensions of the entire structure, depending on the arrangement of the washbasin, toilet and other elements that will be mounted to the Geberit concealed frame.
- The capacity of the cistern is another aspect worth paying attention to. The amount of water drained at one time depends on the shape of the bowl. However, it is worth buying a model that provides several water draining modes depending on your needs. This way you can save a lot on used water.
- The material from which the entire structure is made determines its durability and failure-free operation. It is worth choosing high-quality built-in frames that will serve for many decades without any problems.
- Manufacturer's warranty - pay attention not only to its length, but also to the scope it covers.
- Availability of spare parts - in addition to the warranty, the length of availability of spare parts will guarantee us peaceful use of the bathroom without the need for renovation for many years. Geberit frames have up to 50 years of spare parts availability.
By following these simple tips, you can choose a durable and durable model that will work perfectly in your home.
