Waterproof inspection door under tiling 500x400

Invisible waterproof inspection door 500×400 mm: a hidden functional element for a perfect interior

A unique solution for your home

The ZAVRZ invisible inspection door 500×400 mm is the ideal solution for elegant integration into clad walls. The stated dimension is the sum of the dimensions of the tiles glued to the leaf. The structural opening is as per the drawing documentation in the image. Suitable for standard tile sizes 100×100 mm, 250×200 mm, 500×200 mm and 500×400 mm, this door is a perfect solution that preserves the aesthetics of your space without visible intervention.

Modern and practical "Click" opening

Thanks to the innovative "click" opening system, which is protected by a European patent, we offer a modern solution without the need for visible handles. This system allows easy opening with the option of a tile overlap of up to 20%, which ensures perfect preservation of the joint pattern. Thanks to the option of leaving an overlap, the door is easier to fit and does not need to be manufactured exactly to measure.

High quality of materials

All components of our inspection doors are made of high-quality galvanized steel sheet, which is laser-cut and then bent on a press brake. The door leaves of solid plasterboard are designed for smooth and easy operation even after the tiling is glued on. The smooth operation of the leaf is possible thanks to lapped dural bushings.

The door construction, including its leaf, is made of Siniat LaPlura board, so there is no need to fear a damp environment that would be unsuitable for plasterboard. If the door is placed where water falls directly (e.g. in a shower enclosure), we recommend sealing the joint with silicone and, after it hardens, cutting it with a scalpel. It is precisely for these design adjustments that our waterproof invisible inspection doors are used under ceramic tiling, especially in shower enclosures, where it is also necessary to ensure aesthetic access to water, gas or meter shut-offs.

Aesthetic joint solution

To achieve a visually unified appearance, we offer trims in various shades that perfectly match the colors of your grout. In this way we ensure that the joints between the door and the wall blend in with the overall interior design.

Long service life and trouble-free use

Thanks to the use of high-quality materials and innovative technologies, we guarantee a long service life of our inspection doors and their trouble-free functionality. Our doors differ from the usual solutions on the market and bring not only a practical but also an aesthetic inspection door solution to your home.

How does it work?

The basis of our invisible inspection doors is a specially developed double hinge, protected by a European patent. This system allows the door to slide out in front of the wall and then open smoothly, which ensures easy access to inspection spaces without disrupting the design of your interior.

For this reason, it is necessary to allow for a structural opening depth of 100 mm on the hinge side. Without this preparation, the door cannot be installed.
