The walk-in shower has become one of the most sought-after solutions in modern bathroom renovation and design. Also known in professional projects as a walk-in shower, it is characterized by its seamless integration into the floor.
There are no curbs or steps when entering the shower area, which creates a seamless, accessible, and easy-to-maintain look.
Beyond its design, the walk-in shower represents an advancement in construction methods and requires precise waterproofing along with efficient drainage.
What is a walk-in shower?
A walk-in shower is a shower that is flush with the bathroom floor, where water drains through a built-in slope toward the drain or channel. This continuity between the floor and the shower area creates a sense of spaciousness in the room.
Today, these features seem indispensable in projects that need to ensure greater accessibility to these spaces, especially in the renovation of adapted housing (for people with limited mobility, wheelchair users, or simply those who want to avoid the risk of tripping).
Advantages of Modern Walk-In Showers
We’ve already discussed the first two advantages:
- Minimalist, seamless design
- Accessibility and Comfort
In addition, modern Italian showers offer the following advantages:
- Easy to clean and maintain, as there are no hard-to-reach corners or edges where dirt can accumulate. Furthermore, when combined with the best drainage systems, it prevents puddling by quickly draining water away.
- Versatility in finishes and decor: it can be combined with ceramic tile, porcelain tile, or microcement, adapting to any bathroom style.
- Can be integrated with transparent partitions, walls, or dividing panels ( either built-in or prefabricated waterproof panels) or left without any barriers. The latter option leaves the shower completely open, creating an open, unobstructed space.
- Guaranteed watertightness and durability: When waterproofing membranes and shower systems are installed correctly, the area remains completely watertight, preventing leaks and moisture.
- Compatibility with modern systems: They work perfectly with underfloor heating systems and can be integrated with prefabricated modular systems.
The Italian shower pan
The shower pan is the central element of a walk-in shower, as it ensures that the shower is truly functional. Beyond its aesthetic appeal, its importance lies in its installation, since this determines how water drains, how waterproofing is maintained, and how the space’s durability is ensured.
The slope of the walk-in shower
Although the slope of the shower pan is important for all types of showers—not just Italian-style ones—the difference lies in how it integrates with the floor and creates a seamless look.
In this case, the slope is critical for:
- let the water flow into the drain.
- Get the floor dry as soon as possible.
- ensure safety by preventing slips caused by standing water.
- Prevent leaks from spreading beyond the shower area, which could compromise the bathroom’s structure and cause moisture damage to walls and floors.
Waterproofing Walk-In Showers
Waterproofing is one of the fundamental pillars of the walk-in shower, since—unlike traditional showers, where the curbs act as a barrier—the walk-in shower requires a system that protects the flooring and adjacent structures. Proper waterproofing of a walk-in shower prevents leaks into walls and floors, as well as condensation, mold, and efflorescence, and ensures the durability of the components.
To achieve this, it is essential that a waterproofing membrane cover the entire area that may be exposed to water, including both the shower pan and the area adjacent to the floor of the walk-in shower that may get wet during use. This includes corners, wall junctions, and utility penetrations, which can be reinforced with Water-Stop’s thermoformed accessories. It is recommended to install the membrane up to a certain height on the walls to protect the entire system from splashes.

In addition, it is important that this sheet seamlessly integrates with shower drainage systems, creating a continuous seal for a watertight installation. In this case, shower channels for walk-in showers are the most popular options. The chosen wall and floor tiles can be installed over them to customize the bathroom to individual tastes.
The Prefabricated Walk-In Shower: Quick Installation and Waterproofing
In addition, for builders who want to work quickly and efficiently, there are complete shower systems for walk-in showers that include a precast shower pan, a waterproofing membrane, and a drainage system (grate and drain).
These kits can be easily cut with a utility knife to fit different spaces and are suitable for tiling. They feature a 2% slope in the shower pan and a drainage flow rate of 49 liters per minute.
When installing this prefabricated kit, the shower pan and its liner must be installed below floor level so that they are flush with the floor.
We hope this article on what an Italian shower is and why it’s trending has helped you learn more about it. We invite you to learn more about the waterproofing systems that make its installation possible on the Guru website or in its catalog.
