A walk-in shower requires adequate space

Walk-in showers are arranged not only in large bathrooms, but also in small bathrooms in apartment blocks. When deciding on a walk-in cabin in a small bathroom, you need to think carefully about the size and layout so that the user has full freedom of movement while bathing and the water does not spill out of the shower area. In spacious interiors, it is easier to fully expose the visual values of a walk-in shower. On the other hand, owners of small and awkward bathrooms often arrange a shower in a recess, which, in combination with recess doors, allows for the elimination of the shower tray and avoids flooding the floor.

A walk-in shower needs proper drainage

Optimal water drainage is the basis for comfortable and trouble-free use of a shower cabin. Drainage should be adapted to the technical conditions of the bathroom and to personal preferences. The drain should be made of solid materials, resistant to corrosion and cleaning agents. When choosing a modern walk-in shower, you can choose from two main solutions for water drainage: a linear drain and a point drain.

A linear drain (also known as a linear drain or shower gutter) ensures effective drainage of large amounts of water from the shower cubicle. It also looks stylish and discreet. Its visible element is a decorative grate that is mounted on a level line with the tiles. Linear drains come in a wide range of designs and lengths, which makes it easy to match the model to the individual needs and style of the shower area. A linear drain and siphon require an appropriate amount of space in the floor, which is often an obstacle in so-called old buildings. Instead of the popular linear floor drainage , a wall linear drain can be used. The wall model does not require interference with the floor or creating such a large slope as the floor version. In addition, it creates unlimited possibilities in terms of floor finishing and allows for an extremely elegant aesthetic effect. A linear wall drain is often chosen by owners of bathrooms where it is not possible to install a floor drain. When choosing a linear drain, pay special attention to its capacity. This parameter indicates the speed of water drainage into the sewage system. In addition, an important feature of linear drainage is the method of cleaning. Currently, most models available on the market provide convenient cleaning of the siphon from above. After a quick removal of the cover, you can thoroughly wash the gutter and empty the siphon of hair and other dirt.

A traditional and universal solution for a walk-in shower area is a point drain (also known as a bathroom drain or floor drain). It can be installed anywhere in the bathroom where water needs to be drained from the floor.

It is worth separating the walk-in shower from the rest of the bathroom

The walk-in shower area is usually separated from the rest of the bathroom in order to avoid flooding the floor outside the shower, reduce the humidity level in the room, improve thermal comfort during bathing or provide an intimate atmosphere. Even if you plan to arrange a walk-in shower in a specially prepared alcove, the installation of a shower screen may be unavoidable. There are various solutions to choose from: single- and multi-element shower walls, alcove doors or full shower cabins.

A safe choice will be tempered glass, from which, for example, the walk-in shower cabin with black INVENA profiles was made. This type of glass, if broken, breaks into small pieces, eliminating the risk of injury. Modern shower walls and cabins are often enriched with special coatings, thanks to which they become easy to keep clean and maintain a beautiful shine. Cleaning a surface finished with such a layer may be limited to rinsing with running water after bathing.
