How to Choose the Right Linear Screed Drain for Your Bathroom


Luxury, modern hotels or those with a disability-friendly wetroom often have no large visible drain. Instead, you have what’s known as a linear screed drain. Favoured in commercial settings for their sleek, aesthetic appeal, customisable options and quick turnaround installation, linear screed drains are now becoming popular in domestic settings. Here, CCL Wetrooms looks at everything you need to know about these sought-after designs.

Linear screed drain installation ideas

Luxury homes are using wetrooms to create rooms that flow seamlessly into one another and provide relaxing spaces for showers. For example, a construction company that CCL Wetrooms recently worked with chose a linear screed drain in silver to complement the other bathroom accessories and create a way that a waterfall shower could be included without feeling confined (shown in image one). Another project is depicted in image two. For this luxury development, a marble infill over a linear screen drain created the illusion of a seamless floor.

Linear screed drains are fantastic for providing options for wetrooms to have a seamless floor, and they can be customised for any type of floor. But how do you go about choosing the correct finish, as seen in the above examples?

Choosing the right linear screed drain

When choosing linear screed drains, you first need to know what floor you have below. Whether it’s timber or a concrete floor, there are different options available. It’s also worth looking at the depth you need as this also will help inform the type of drain you will need to choose.

Linear screed drains for shallow installations

Shallow floors are typical in renovation projects, where there is less scope to add height to a room. Here, an adjustable but shallow linear screed drain is helpful, as regardless of the depth of the space available, there will be an option to fit. Extra shallow brackets can offer minimum heights of 38mm, which is perfect when there is little wiggle room in a project.

Linear screed drains for high-flow rate requirements

Where a shower produces a high flow rate, linear screed drains are often not used as there is a common misconception that they will not handle the increased flow rates.

With multiple trap outlets, a good linear screed drain will be able to handle flow rates of up to 70 litres a minute, which is what a high-pressure drenching head will produce. If you’ve got a high-performance shower, then choose a linear screed drain with three trap outlets to accommodate the flow.

Mosaic tiles and linear screed drains

Often, linear screed drains are thought of with large stone tiles, and mosaic rooms are unable to happen with a linear screed drain. With a four-way fall, mosaic tiles can be used – and to great effect. These drains sit in the centre of the floor over by the wall. A four-way fall drain allows for smaller tiles or drains with awkward cuts required. They also suit a square wetroom unit or a smaller room.

Linear screed drains on a timber floor

When installing on a timber floor, waterproofing entirely is essential to ensure the timber does not rot. Therefore, installing a linear screed drain requires a pre-formed base to assure safe and secure installation. Linear screed drains of all types can be installed on a timber floor as long as a good standard of waterproofing is in place.

Domestic installation options for linear screed drains – things to remember

In a domestic situation, when installing a linear screed drain, it can be hard to know what to use. CCL Wetrooms’ ideas above will help to make your decision on what kind of trap, but there are additional considerations to bear in mind:

1. Is your floor perfectly even?
If your floor isn’t perfectly even before installing a wetroom, you will need to add in a levelling solution. Due to the minor adjustments that affect the performance of a wetroom floor, levelling is incredibly important.

2. Does your wetroom need to fit specific accessibility requirements?
If a wetroom needs to fit additional needs, then planning these in from the beginning is essential. The needs of the people involved may mean multiple drains are required in locations across the wetroom or a specific fall angle. You should discuss all these with a wetroom specialist to help inform the type of drain you need.

3. Do you want to include underfloor heating?
Underfloor heating in wetrooms is a popular choice as it means that often cold tiles will not be cold, even in winter weather. However, placing your underfloor heating may require specific heights of floor, which, in turn, will impact the type of linear screed drain you can use.

4. Have you made a particular choice on the flow rate needed?
If you’re planning to increase the flow rate of your shower at any point, you will need to consider this when planning a wetroom, as it is not possible to add further drainage traps after the installation of a wetroom floor. Therefore, overestimating and establishing a specified flow rate before installation is vital to ensure the longevity of your wetroom.
