FAQ

How is the transition between the tile and the Fundo element sealed?

The transition is sealed using a standard aluminium profile (30 × 30 mm), a strip of sealing tape, and wedi 610 adhesive sealant.

Is the shower wheelchair accessible?

That depends on the chosen surface.
All wedi Top surfaces – except the marble versions – are wheelchair accessible.

If tiling is used, the tiles should be at least 5 × 5 cm in size.
The shower area must also be accessible. In Germany, a clearance area of 150 × 150 cm is usually required – please check local building regulations for other requirements.

Can a seat be installed at a later stage?

Of course – a seat can also be installed at a later stage, as the waterproofing is already in place.

The wedi Sanoasa corner seat is 100% compatible with the system and can be retrofitted without any issues.

For other seat types – such as fold-down seats – please note that reinforcement plates must be installed before the surface or tiles are laid.

How long does the full renovation process take?

The total renovation typically takes around 48 hours, depending on the project and drying times of the materials used.

Important drying time considerations:

Silicone joints must fully cure before being subjected to stress

Waterproofing slurries may require up to 3 days to dry before the shower can be used

Always refer to the relevant manufacturer’s instructions for proper curing and drying times.

How do we level the wall behind the bathtub?

You can use a thin wedi building board to align with the tile level – thicknesses from 4 mm to 100 mm are available.

Alternatively, a 20 mm board can be applied using a dot-and-dab technique, which is ideal for uneven surfaces.
Please follow the official application guidelines to ensure proper installation.

Can the system be installed on timber floors?

Yes, absolutely.
We recommend using the wedi Fundo Ligno Plus (23 mm), which has been specially designed for use on timber floors and wooden substrates.

It offers a safe and reliable solution for refurbishments in older buildings and sensitive floor constructions.
