Have you flashed a tiled shower for your new bathroom? Do you now need a drain or shower drain to ensure proper drainage and prevent stagnation of wastewater? How to choose your drain or shower drain?

Here is a small practical guide to help you in your choice.

Plumbers use specific technical terms like walk-in shower or zero-step shower. In these walk-in showers, the most important criteria to remember are:

Evacuation capacity

If you dream of an XXL shower with enveloping rain, the choice of emptying is essential: you will have to choose one with sufficient drainage capacity to avoid the risk of overflow or flooding.

The NF standard (EN1253) requires, for a supply (at the outlet of the valve) of 12 l / min, a minimum of 24 l / min for a tube outlet D. 32 mm, 36 l / min for a tube outlet D. 40 mm and 48 l / min for a tube outlet D. 50 mm.

The maintenance of the drain or the shower drain is essential over time to remove deposits of hair, dead skin, soap or limescale, avoid any clogging in the pipe and thus guarantee long-lasting hydraulic performance.

Built-in height

A large number of floor heights do not allow you to install a shower at ground level, check the possible disbursement height in your configuration to take this element into account before any installation in your water feature.

Today, manufacturers such as VALENTIN are developing ultra-flat drains such as the SMART tiled floor drain (only 80 mm in space) or the PANAMA channel (only 66 mm in disbursement).

The new generation drains allow the installation of a walk-in shower with impeccable finishes and design.

Slope effect

Indispensable to get the water out of the shower!

Effet de pente

In the bathroom, in the kitchen or any water room, the sanitary equipment is connected to a collection of wastewater evacuation to the sewer pipe.

Depending on the layout of the rooms, the location of the sanitary equipment is more or less distant from the vertical descent, collecting towards the sewer.

The essential parameter for a good sanitary installation is the slope effect.

The rules of the art of plumbing mentioned in the DTU require a minimum regulatory slope effect of 0.75 ° to facilitate the flow of water.

The key word is the drainage rate, which allows the shower tray or the shower area, the sink, the sink or the bathtub to be emptied more quickly. Facilitating the flow of water also helps prevent dirt from stagnating or settling in the pipes.

Indeed, any deposit creates an obstacle which risks reducing the performance of the emptying.

The steeper the slope, the better the flow performance. VALENTIN shower drains are designed with an integrated slope effect of 2.5 ° which represents a slope of 5.5 cm per meter, much greater than the slope effect required by the DTU. This design increases the evacuation speed and limits the risk of clogging.

Hole position

Several options are possible! The waste can be mounted in the center, close to the wall or on the sides.

However, make sure that the dump is compatible with the type of installation chosen.

Finally, the location of the flow also determines the slope effect.

Direction of flow

The flow can be vertical or horizontal. You must select a vertical model for floor exhaust and horizontal for wall exhaust.

Horizontal exits are the most common.

VALENTIN has developed the GOULUE drain which has a multidirectional outlet and which makes it suitable for all installations: vertical, horizontal or any intermediate position.

Water seal

The water seal is the constant reserve of water systematically created in the siphon and which makes it possible to shield the rise of odors from the wastewater network towards the interior of the house. The height of the water seal is therefore essential to ensure this role.
