wedi Sanwell shower niche – prefab recessed niche with clear dimensional logic
The wedi Sanwell shower niche is a prefabricated recessed niche developed for fast, waterproof and perfectly aligned installation in shower walls and bathroom constructions. Because the niche is delivered as a complete prefab element, it is fully waterproof, precisely square and immediately ready for tiling. This eliminates alignment errors, uneven edges and complex sealing details during installation.
Clear connection between product name and dimensions
On the website, the Sanwell niches are offered under fixed product names such as 20/40 and 30/60, combined with a frame flange thickness of 10 mm or 12.5 mm. These designations directly refer to the exact internal dimensions of the niche:
- Sanwell niche 20/40 → internal dimensions 434 × 234 mm
- Sanwell niche 30/60 → internal dimensions 634 × 334 mm
The total external dimensions consist of the niche body plus the surrounding frame flange. This results in the following fixed and clearly defined external sizes:
- Sanwell niche 20/40 → external dimensions 654 × 454 mm
- Sanwell niche 30/60 → external dimensions 854 × 554 mm
Frame flange 10 mm or 12.5 mm – how to interpret this
The frame flange is the surrounding edge of the niche that ensures a precise connection to the wall construction. The selected flange thickness directly corresponds to the thickness of the wedi building boards used:
- 10 mm frame flange for wall constructions using 10 mm wedi boards
- 12.5 mm frame flange for wall constructions using 12.5 mm wedi boards
This ensures that the niche sits flush with the finished wall surface after installation, resulting in a clean and professional appearance without additional leveling work.
Installation depth of 70 mm or 100 mm
The wedi Sanwell shower niche is available with an installation depth of 70 mm or 100 mm. This depth determines both the available space inside the wall and the usable depth of the niche. The correct option depends on the wall build-up and the available installation space behind the niche.
Expandable with wall modules and Sanwell Top finishes
The standalone Sanwell niche can be combined with complete wedi wall modules in which the niche is already prefabricated. In addition, wedi Sanwell Top and Sanwell Top LED finishes are available. These tops provide a seamless, tile-free alternative that offers a refined, low-maintenance and fully waterproof finish inside the niche.
