Transforming a bathroom into a wet room is an exciting project! But diving into it can feel like learning a new language. You might see terms like “former,” “former former,” or “drainage former” and wonder what they mean and if there’s a simpler way. Don’t worry, we’ll break down these common wet room glossary terms and explore their practical alternatives. You’ll gain the confidence to discuss your project and make informed decisions for a beautiful, functional, and waterproof space. Let’s get started on making your wet room dreams a reality!
Decoding the Lingo: Your Wet Room Glossary
Embarking on a wet room renovation can bring you face-to-face with specialized terminology. Understanding these terms is key to selecting the right products and communicating effectively with suppliers or installers. Let’s demystify some common wet room vocabulary.
Former vs. Former Former vs. Tray
These terms are largely interchangeable in the context of wet room construction. They all refer to a purpose-built, rigid board designed to sit on your subfloor. Its primary job is to create the essential gentle slope (typically 1-2%) that directs water towards a drain. These are often made from materials like XPS (extruded polystyrene) for its insulating properties, water resistance, and ease of use.
- Former: The most common and straightforward term.
- Former Former: Sometimes used to emphasize that it’s the primary former for the wet room floor.
- Wet Room Tray: A descriptive term that highlights its function of forming the “tray” area of the shower.
- Shower Former: Another descriptive term focusing on its role in the shower enclosure.
Why are they important? A former ensures that water naturally flows away from the shower area without pooling. This is fundamental to preventing leaks and water damage to your subfloor and surrounding bathroom structure. Without this gradient, water would simply sit on the floor.
Drainage Former
This term often refers to a former that has a drain outlet pre-integrated or specifically designed to accommodate a drain. Some formers come as a complete unit with a drain channel built-in, for example, a linear drain former. Others are simply the sloping board onto which you will install a separate drain fitting.
Linear Drain vs. Point Drain
These refer to the TYPE of drain you will install within your wet room. The choice impacts how the former is constructed and how the floor slopes.
- Linear Drain: A long, slim channel drain. It requires a single, gentle slope from the high point of the wet room floor towards the linear drain, usually installed along one edge of the shower area or against a wall. They are modern, sleek, and can be more efficient as they require less fall. For more on shower drain types, check out resources like This Old House’s guide to shower drains.
- Point Drain: The traditional, circular drain. This requires a four-way slope from all surrounding areas of the shower floor towards the center where the point drain is located. Achieving a perfect four-way slope can sometimes result in a slightly steeper gradient in the shower floor, and they may look less contemporary than linear drains.
Screed (vs. Former)
Screed is a mixture of sand, cement, and water used to level floors and create gradients. In wet room construction, you can use screed to build the required slope for drainage.
- Screed Method: This involves laying and shaping the screed mix onto the subfloor to create the precise gradient. It needs to be carefully applied and allowed to cure fully, and crucially, must be thoroughly waterproofed before tiling.
- Former Method: This uses a pre-made, rigid former as described above. It’s generally considered simpler and more reliable for DIYers as the slope is pre-fabricated.
Considerations: While screed can be a cost-effective solution for large areas, it’s more labor-intensive and requires a higher level of skill to get the slope and waterproofing right. Formers are often lighter, quicker to install, and provide a guaranteed watertight base when installed correctly.
Waterproof Membrane
This is the critical barrier that prevents water from penetrating the floor and walls. After the former is installed (or screed is laid and cured), a waterproof membrane is applied. This can be a liquid-applied substance (like a paint-on coating) or a special sheet membrane designed for wet areas.
- Liquid-Applied Membranes: These are painted or rolled onto the surface, creating a seamless, flexible, and waterproof layer. They are excellent for covering complex shapes and junctions.
- Sheet Membranes: These are large sheets of waterproof material (often rubber or bitumen-based) that are sealed together at the seams and adhered to the substrate.
Proper application of the membrane, paying close attention to corners and edges, is vital for a watertight wet room. Manufacturers like Schlüter-Systems offer comprehensive ranges of waterproofing systems designed for wet rooms.
Wet Room Glossary Term vs. Alternative: Making the Choice
Now that we’ve demystified the terms, let’s dive into the “vs.” aspect. When considering a wet room, you often face a choice between different types of components or methods. Understanding these options will help you decide what’s best for your project.
Forming the Slope: Former vs. Screed
This is one of the most significant decisions you’ll make. A former offers a standardized, pre-made solution, while screed offers more flexibility but requires greater expertise.
| Feature | Wet Room Former (e.g., XPS Board) | Screed Method |
|---|---|---|
| Ease of Installation | High. Pre-sloped, lightweight, many are “cut-to-fit”. | Moderate to Difficult. Requires mixing, accurate screeding, and curing time. |
| Guaranteed Slope | Yes. Pre-defined gradient (usually 1-2%). | Requires skill to achieve consistent slope accurately. |
| Waterproofing Integration | Formers are usually waterproof themselves and provide a stable base for membrane. | Screed itself is not waterproof. Extensive and meticulous waterproofing is essential. |
| Time Required | Faster installation. | Longer, due to mixing, application, and curing. |
| Cost | Can be higher upfront for the former itself. | Materials can be cheaper, but labor costs can be higher. |
| DIY Friendliness | Very high. Recommended for most DIYers. | Low to moderate. Best left to experienced tilers or builders. |
Drainage Options: Linear vs. Point
The type of drain you choose will impact the required slope and the overall look of your wet room.
- Linear Drains:
- Pros: Modern aesthetic, requires only one-way slope, can be more efficient with water removal, generally more comfortable to stand on (no stepping over a central drain).
- Cons: Can be more expensive than point drains, installation requires careful alignment against a wall or edge.
- Point Drains:
- Pros: More affordable, widely available, simpler plumbing connections for some.
- Cons: Requires a four-way slope which can be trickier to get perfect and might feel steeper underfoot, can be a visual focal point (which may or may not be desired).
Recommendation: For most modern wet rooms, especially those embracing a minimalist or luxury feel, linear drains are often preferred. They are also excellent for accessibility as they create a level entry and a single, gentle slope.

Waterproofing Method: Liquid vs. Sheet Membrane
Both methods achieve the same goal: creating a watertight barrier. The best choice often depends on the specific area, substrate, and installer preference.
| Feature | Liquid-Applied Membrane | Sheet Membrane |
|---|---|---|
| Application | Brushed or rolled on. Requires multiple coats. | Laid out and adhered, seams sealed with tape/adhesive. |
| Corners & Junctions | Excellent for sealing complex details and junctions seamlessly. | Requires careful detailing and sealing at corners and penetrations. |
| Curing Time | Varies, but typically dries to allow tiling within 24-48 hours. | Immediate once adhered and sealed, but some adhesives may need time. |
| Flexibility | Generally very flexible, accommodating minor substrate movements. | Can be flexible, but seams are critical points. |
| DIY Friendliness | Good if applied carefully and ensuring full coverage. | Requires precision with cutting and sealing seams. |
Expert Tip: Regardless of the method, ensure you follow the manufacturer’s instructions precisely. Pay extra attention to wall-to-floor junctions, around drains, and any pipe penetrations. For ultimate peace of mind, you can even use a combination – a liquid membrane on the walls and a sheet membrane for the floor, for instance.
A Simplified Step-by-Step: Preparing Your Wet Room Floor

Frequently Asked Questions About Wet Rooms
What is a wet room former?
A wet room former, also known as a wet room tray or former former, is a pre-formed sloping board. It’s installed directly onto your subfloor to create the necessary gradient for water to drain away. Think of it as the foundation for your wet room shower area, ensuring water flows to the drain and not elsewhere.
What are the benefits of using a wet room former?
Formers are great because they simplify creating a precise slope. They are waterproof, durable, and easy to tile over. They help prevent leaks and water damage by ensuring proper drainage. Many are lightweight and easy to cut to size, making installation smoother.
Can I create a wet room without a dedicated former?
Yes, you can. It’s possible to build the slope using screed (a cement-based leveling compound). However, this requires careful calculation and execution to ensure the correct gradient and waterproofing. It’s a more traditional method and can be more time-consuming and prone to errors for beginners.
What is a linear drain in a wet room?
A linear drain is a long, narrow shower drain. It’s installed at a single edge of the shower area, typically against a wall or in the center. Linear drains are excellent for wet rooms as they require a single, gentle slope towards them, making them aesthetically pleasing and efficient.
What is a point drain?
A point drain is the more traditional, circular shower drain. It’s located in the center of the shower area and requires a four-way slope from all sides of the shower floor towards it. While functional, they sometimes necessitate a steeper slope, which can be less comfortable underfoot.
How do I waterproof a wet room shower area?
Waterproofing is crucial. You’ll typically use a liquid-applied membrane or sheet membrane. This is applied over the former (or screed) and all wall junctions before tiling. It creates a seamless, watertight barrier, preventing moisture from reaching the subfloor and walls.
