The applications

We have greatly simplified our portfolio. There are two pre-wall applications. For dry constructions we offer Prevista Dry for in-wall and support profile installation. For wet constructions we offer Prevista Pure. All systems feature the same cistern. This means you can assemble and install your pre-wall system in super-quick time.

Wet construction

State-of-the-art pre-wall technology combined with tried and proven methods: With Prevista Smart and the new cistern, custom, high-grade, durable wet construction installations can be created.

Prevista Smart

"Smart" is a byword for wet construction techniques on the international market. Accordingly, our Prevista Smart pre-wall blocks are tailored to wet construction requirements. They are highly flexible for use in individual installation projects. Blocks are available for WCs, urinals, washbasins and bidets, each in two height variants: 820 mm and 1070 mm.

Fully pre-assembled

To make it easier for you, the interior fittings with the Prevista cistern come fully pre-assembled, and permit operation from the front. The 820 mm variant can also be easily operated from above. The flexible height adjustment additionally enhances variability in installation.

Dry construction

Our new Prevista Dry pre-wall application for in-wall and support profile installation is a great aid to dry construction projects thanks to its wide range of innovative functions. It is robust in finish, so assuring maximum reliability.

Prevista Dry

Prevista Dry Plus also allows more unusual wishes to be met. The rail system provides for a high degree of design freedom while also being quick to install.

Quick and easy installation

After the preparatory work, such as drilling the holes, Prevista Dry can be installed using just three tools: a folding rule, a spirit level and a size 13 spanner. As in the case of the cistern, all components that can be installed without the use of tools are coloured yellow. And Prevista Dry is extremely easy to mount on a wall: Solutions such as the wall bracket additionally save time thanks to their flexibility.

Intelligent quick-release clamps

Height-adjustment of water connections and urinal and washbasin drains used to be very time-consuming. The new quick-release clamps have revolutionised the procedure, and offer high levels of stability matching any screw-fit connection.

Functions for more customer comfort

A key concern in future will be age-appropriate bathroom design. Viega Prevista has established the preconditions to meet those needs by making its installations height-adjustable as standard, as well as offering the facility to install shower WCs of any widely-used make.
