Mount vanity unit without wall line damage

When mounting a vanity unit in the bathroom, there are two special challenges in wall mounting. In the wall running lines and supply shafts must not be injured and bores are often made on tiled surfaces. On-site basic rules help with damage-free installation.

Pipes, pipes and shafts

When buying vanity units as finished product, there are self-standing and wall-mounted models. While only the assembly instructions of the manufacturer have to be followed for self-standing versions, some possible pitfalls must be considered when fixing them to the wall.

Naturally, bathrooms have water pipes and pipes in the walls. Especially in the vicinity of the later taps such as taps on sink, tub or shower are expected both supply lines and sewers, manholes or slots. The concealed installation follows in modern buildings fixed building rules, which determine the course. In older houses, you can not rely on it.

Not only the pipes themselves are endangered by tapping. Water pipes often run in masonry slits, shafts or canals. They are usually closed only with a thin cover plate, above the plaster or tiles. Boreholes do not pick up dowels and do not hold a vanity unit like a vanity top.

Visual inspection and conclusions

The on-site basic rule when laying cables of all kinds provides an always vertical or horizontal course. For this reason, it is already possible to draw conclusions about the performance characteristics from the visual inspection of the existing connecting pieces and taps.
In the vertical direction canals and pipes below wall taps, water heaters and water meters are expected. Outlets run horizontally from the spigot. Here, special care must be taken to ensure that the diagonal slope for the process. The slopes are not precisely met by all craftsmen. Therefore, holes below the nozzle height should generally be avoided.

Drilling in tiles

Another challenge is drilling into ceramic tiles. If possible, joints should be drilled instead of tile surfaces. Drill holes on the tiles must be at least twenty millimeters from the respective tile edges. Bursting or tearing is avoided by pre-drilling a small hole (up to six millimeters) and then drilling to the required size.

Tips & Tricks

When drilling into tiles, the rotational speed of the drill plays an important role. Starting at one thousand revolutions per minute, the risk of damage is reduced.
