When it comes to specifying sanitaryware for new bathrooms or bathroom refurbishments, wall-hung is by far the most hygienic, low-maintenance solution available, as it not only offers the latest in contemporary styling but also has many practical benefits for both the installer and customer.

With all pipework neatly concealed within the wall, wall-hung sanitaryware helps to create a modern, streamlined profile and is far more contemporary in design than traditional, close-coupled WCs which have visible cisterns and pipework.

As well as being aesthetically pleasing, this also means that wall-hung sanitaryware makes light work of cleaning, as the floor can be mopped right underneath the pan, with no awkward nooks and crannies for dirt to get trapped, so no need to get down on bended knees to clean. Furthermore, concealed pipework helps to significantly reduce the noise caused by flushing and the cistern refilling, making for a far more restful, discreet environment for the end-user.

The good news for installers is that the installation isn’t as complex as many think. Opting for wall-hung sanitaryware can significantly reduce installation time, with systems such as those using the Duofix frame from Geberit being simple to install and supplied already equipped with all the necessary industry-standard plumbing equipment for a quick, hassle-free connection.

Manufactured from high-grade welded steel which is rigorously tested to support weights of up to 63 stone, Geberit’s concealed support frames make wall-hung sanitaryware suitable for use by all, while maintenance couldn’t be easier as access to the cistern is via the flush plate, which can be removed and replaced without the need for tools.

Step 1
For this particular installation we used the PreWall method, which allows you to construct a duct in front of an existing wall to hide the plumbing and drainage. First, measure and mark out the wall and floor, taking into account the finished floor levels. You can now drill the wall and floor fixing holes.

Step 2
The frame can now be adjusted to the correct fitting height. This is done by placing your feet onto the floor brackets and lifting the frame to the desired height. Once you have the correct height, the legs are self-supporting and will allow you to release the top of the frame and tighten the locking bolts.

Step 3
At this stage the PreWall brackets are fitted to the frame and rawl plugs are fitted into the relevant holes. The frame is then offered up to the wall, and the wall and floor brackets are bolted up. The plastic packing piece can now be fitted to the wall bracket.

Step 4
The wall bracket is adjustable in and out to ensure that the installation is plumb. At this stage, final adjustments should be made to adjust for level, which is done by slackening the lower frame locking bolts and moving the frame to ensure level installation. Once the level has been set, you can adjust for plumbness by adjusting the PreWall bracket screw. Once you are happy that the frame is plumb, then the plastic locking nuts can be fitted.

Step 5
Now you can make your plumbing and drainage connections to the Geberit Kappa cistern frame. The stud work and plasterboard can now be constructed and the tiling can be completed. At this stage you should fit the WC pan.

Step 6
The final steps are to turn on the water supply via the integral isolating valve and set the flush volume, which is standard at 6/3 litres.

Step 7
You can now proceed with fitting the flush plate. In this case we used the Artline model, but all plates are fitted in the same way. You should pay careful attention to adjusting the push rods correctly to ensure correct dual-flush operation. The installation is now complete. All future maintenance and adjustment is done via the access hole provided by the flush plate.
