Design virtually any wet room shower floor using 3 simple components

Design any size or shape of wet room floor using a simple modular system

The Basics of a wet room shower

A wet room shower floor is essentially a slope towards a drainage gully. Easy to describe but not so easy to get right if you try to create it manually. Those wise in such construction use floor formers - prefabricated floor sections incorporating a pre-formed slope. This saves a great deal of time (which is money) and guarantees you get things right - first time. But there are occasions when the shape and size required cannot be found amongst the numerous one-piece formers.

The VARI DECK is a superb modular system allowing a simple step by step approach to create your own wet room shower floor and allows the design of virtually any size or shape on a timber floor using a linear drain. What's possible is limited only by your creativity!

With just a few simple components you can achieve limitless variations. It's just a matter of deciding on:

How big your wet room shower area is going to be, and
Where you want the linear drainage gully to sit (e.g. against the wall, just off the wall or in the centre of the shower)

Where to begin

Whatever size of shower area you intend to create, there is always one constant - you need to get the water away. So we begin with the drainage component. You simply need to decide where you wish to place your linear drain and how long the gully will be.

The VARI DECK drainage component

This is the central element of the modular wet-floor system and can be trimmed on site to size. The drainage component is available with 1, 2 or 3 outlet traps that can achieve a flow rate of up to 68 l/m, and with a choice of gully grills from 600mm to 2000mm wide.

The drainage component (as supplied) is 1200mm x 300mm. This can however be trimmed according to requirements. The 1200mm length can be reduced to 660mm (minimum) and the 300mm depth reduced to 220mm (minimum) if a wall drain configuration is required.

Gully length

When placing the drainage component and gully in proximity to a wall you have a choice of two positions - against the wall or set away from the wall.

You can choose how long the gully will be. You might for example want a smallish grill to be visible when finished, or you might require the grill to extend all the way across an alcove from wall to wall.

With this modular system the choice is yours. Gullies are available in 15 standard sizes from 600mm to 1500mm, and up to 2000mm in custom made sizes! If one of the standard sizes is not suitable then a Fast-track bespoke manufacturing service is available.


The drainage component is supplied 1200mm long and 300mm wide, but can be trimmed according to requirements. In the event that you require a gully longer than the drainage component, the wings of the gully simply extend beyond.

Grill (gully cover) type

The drainage gully has a cover or grill. This is what you will see when your wet room shower is finished. As with all other components in this range you have a choice.

You can choose to have a cover which can be

Grill options

1. Solid stainless steel (G1)	2. rebated to allow a tile to be inserted (G3)

Special order grills

3. Stainless steel with square holes	4. Slotted stainless steel

5. frameless, making it near invisible

The slope to the gully

Once the location of the drain component is determined, it is a simple case of creating the slope in the floor to the gully using tapered boards.

The tapered boards are manufactured using a high density UPS core with a mineral coating making them lightweight and easy to handle, whilst retaining good thermal properties and compressive strength. The thicker (outer) edge of the board is 22mm (the same as a standard flooring board) with a pre-engineered gradient to 11mm (where it meets the drainage component).

Tapered boards (that can be used singly or in conjunction with others to create a larger shower area) can be trimmed easily on site for a perfect fit.

VARI DECK Components and prices

Vari Deck is a comprehensive modular wet room shower floor system. Its capabilities are extensive which makes it suitable for creating particularly large or unusual wet room shower floor areas. If you have such a project we invite you to send us a sketch or drawing of your design with dimensions. We will produce a 'shopping list' of components required and a quote.

For many projects requiring a gully against the wall you might find the MONO DECK KITS a much simpler way to go. These are essentially VARI DECK but packaged to suit the most popular sizes. The kits are available in eight kit sizes and include all the components (Gully and Cover, Waste Outlet, Tapered Board etc). Additions and variations to each kit are easily made.

We would always advise you to send us a drawing/sketch of your project so we can make sure your choice of MONO DECK KIT will be correct for your wet room shower area.
