The walk-in shower seduces with its sleek design, accessibility and comfort. However, its implementation requires great rigour, especially in terms of plumbing. Poor installation can lead to leaks, odours or water infiltration. What are the main mistakes to avoid to guarantee a functional and long-lasting walk-in shower?
Make sure of the possibility of digging
Even before starting the work, it is first necessary to check if the soil allows enough digging to integrate the sink and the evacuation system. Walk-in showers require a slope and a syphon embedded in the slab, which is not always feasible, especially in renovation or apartment. A prior assessment of the structure is essential.

Manage the evacuation of water well
One of the most sensitive points concerns the flow of water. An insufficient or poorly oriented slope can lead to stagnation or even overflows. We recommend a slope of 1 to 2% towards the syphon. The diameter of the pipe must also be adapted to the water flow: a pipe that is too narrow could cause congestion.
Ensure tightness
Waterproofing is an essential aspect. A poorly waterproof walk-in shower can cause infiltration into the floor and walls, resulting in mould or damage to neighbours. The use of waterproofing membranes, adapted joints and water-repellent coatings is imperative, without forgetting to treat angles and fittings with care.
Protect yourself against slips
Often designed without a tray for easier access, the walk-in shower can become slippery, especially with a wet tiled floor. To avoid accidents, it is better to opt for a non-slip tile or integrate safety strips. The installation of a grab bar or a shower mat can also improve safety, especially for the elderly.
Do not do the installation without a professional
Even if some experienced handymen may be tempted to do everything themselves, it is strongly recommended to call on a qualified professional. A plumber will be able to assess technical constraints, choose the right materials and guarantee a standard-compliant installation. This not only avoids unpleasant surprises, but also expensive repairs in the future.
