Linear drainage efficiency

First of all, it is worth paying attention to the efficiency of the linear drain. This parameter refers to the amount of water that the drain is able to remove in a unit of time. The higher the efficiency, the better, because it prevents water from accumulating on the bathroom floor and protects against the appearance of unsightly stains on the joints and tiles. Therefore, it is worth choosing   linear drains   with the right flanges and sizes to achieve maximum efficiency. If we are considering a standard bathroom, it is worth choosing a drain with a capacity of around 30-40 liters per minute. However, if the bathroom is larger or has a bathtub, it is worth choosing a more efficient model that can easily handle larger amounts of water.

If we are dealing with a location in a recess, the best option will be drains with a smaller trough size. If the floor is even, you can choose a larger trough size - this way, you can achieve greater drainage efficiency and prevent water from flooding during a shower.

Linear drain size

Another important factor when choosing a linear drain is its size. It is generally accepted that it is best to choose a drain that is 10 cm shorter than the width of the shower cubicle. Therefore, if we use the most popular 90x90 cm shower cubicle, it is worth looking for an 80 cm linear drain. Similarly, for an 80x80 cm cubicle, we choose a 70 cm drain.

What material should I choose for a linear drain?

Another important factor is the material from which the linear drain is made. It is best if it is stainless steel, which is characterized by high corrosion resistance and durability. Linear drains made of this material are also easy to clean, which makes it much easier to keep the bathroom clean. In the case of stainless steel, it is worth paying attention to the quality of the material. Drains made of lower quality steel can rust faster or lose their properties. Linear drains made of plastic and concrete are also available on the market. All of these materials are durable and resistant to rust, which guarantees long-term use.

The last but not least criterion for selecting a linear drain is matching it to the characteristics of the floor. The drain should be suitable for the thickness of the tiles or other floor coverings. If you want to match it to a stone floor, it is necessary to choose a model with adjustable height, which will allow you to adjust it to the thickness of the stone or other surface. In the case of tiled floors, it is worth choosing drains with a lower height, which will make it easier to insert the tiles without creating unevenness.

In summary, choosing a linear drain is an important decision when arranging a bathroom. It is worth paying attention to the efficiency, material and matching to the characteristics of the floor. Thanks to this, we will be sure that our bathroom will be functional, and the linear drain will fulfill its task in an efficient and effective way.
