Bathroom renovation is based on crucial technical choices. Replacing a bathtub with a walk-in shower is a common request, but it requires checking the available drainage slope, which can influence the very structure of the floor.

Furthermore, as the water supplied by the Services Industriels de Genève can be relatively hard, it is strongly advised to plan for easy-to-maintain surfaces to limit the impact of limescale on faucets and shower walls.

The quality level of materials, from tiles to shower trays, also changes the complexity of installation and durability. Options like underfloor heating or high-performance ventilation systems are wise investments to increase comfort. Each choice must be correlated with the existing constraints of the building.

It is essential to anticipate these needs before the design phase to avoid costly changes during construction and ensure that all technical elements integrate perfectly into your space.

Vernier has a building stock marked by high construction activity before 1975, including large ensembles such as Le Lignon and Les Avanchets. For owners located in these types of buildings, bathroom configurations are often standardized.

However, during any renovation, one must be vigilant regarding the possible presence of old materials, especially in dwellings prior to 1990 which may present risks related to asbestos in tile adhesives or joints.

The structure of drainage networks and sound insulation must be subject to in-depth analysis before any intervention. In older buildings, waste stacks and drains may require complete replacement to avoid future leaks.

Prior expertise allows defining whether the slab supports the weight of new, heavier equipment or if an adaptation of the network is necessary. It is imperative to consult original plans to understand the layout of embedded pipes, thus avoiding unplanned destructive interventions during demolition.

In Vernier, as in the entire Geneva territory, a building permit may be necessary depending on the scope of the work.

Although the interior renovation of a bathroom does not generally require a major building permit, any modification affecting the structure, change of use, or a significant modification of the networks may require an approach to the Office de l'urbanisme.

If you are planning additional works, such as the installation of a heat pump with a power exceeding 10 kW, a building permit becomes mandatory.

It is strongly recommended to check with the communal services of Vernier whether your building is subject to heritage protection rules. Certain technical installations, if they affect the exterior appearance or facades, are strictly regulated.

It is preferable to avoid periods of extreme cold, although most work takes place indoors, as logistical conditions and the drying time of materials can be influenced by low temperatures, especially if the building is not perfectly insulated.

After plumbing come screed work, crucial waterproofing to avoid future leaks, then tile laying, and finally finishes. Planning must be realistic: each trade must intervene in a precise order.

An intermediate season, such as spring or autumn, is often ideal to minimize inconvenience related to heating and ventilation during the phase when the bathroom is out of service. Good communication with local artisans is the best way to synchronize these steps without superfluous delay.

To succeed in your project in Vernier, avoid classic errors by preparing thoroughly. Never start work without having clarified the capacities of your existing drainage networks. Never underestimate the drying time required between each step.

Ensure you have obtained all necessary agreements before ordering expensive materials. Do not neglect ventilation, as a poorly ventilated bathroom quickly generates mold. Do not choose faucets that are difficult to clean without considering local water hardness.

Here is your checklist : Check the drainage slope before choosing your shower. Plan for a duration of 2 to 4 weeks without a bathroom. Request detailed comparative quotes by specifying your heritage constraints if applicable.
