Invisible Square Shower Drain

Sophisticated Hidden Drain System: Our Invisible Linear Drains are engineered with a concealed system that utilizes the perimeter joints of tiles. This innovative design allows the water to invisibly flow through the base until it reaches the drain outlet, maintaining a seamless and elegant appearance in your bathroom.

Streamlined Easy Installation: The modern waterproofing process of our invisible drains includes our premium Superdry waterproof membrane, simplifying the installation.
For a flush, curbless shower finish, consider our Recess Floor Bracket Kit, which allows for effortless recessing of the wood subfloor. Alternatively, for a curb shower, our prefabricated curbs integrate smoothly, offering flexible design options.

Seamless Step-Free Experience: Enjoy an uninterrupted and barrier-free shower experience with our invisible drains, designed for a homogeneous tile flow. And for those who prefer a curbed shower, our design is adaptable to include a curb without compromising the integrity of your shower's design.

Enhanced Thermo-Sealed Waterproofing:

We've fortified our drains with thermo-sealed waterproofing along the edge, ensuring complete sealing at the most vulnerable points. This additional layer of protection contributes to the longevity and water resistance of your shower system.

Optimal Cleanliness: Our invisible drains are not only self-cleaning but also treated with antibacterial and fungicidal agents, ensuring the highest sanitary standards. The surface allows for easy lifting of the tiles, providing access for thorough cleaning as needed.

Designed for Large-Format Tiles: To achieve a uniform and attractive finish, our invisible linear drains are compatible with large-format tiles that span the entire drain area. This compatibility ensures a continuous and visually appealing look for your shower floor.

Low-Profile Design for Versatility: With a slim height of just 0.78 inches (20mm), our drains are perfect for installations on various subfloor types, including wood and concrete. This low profile design ensures that integrating an invisible drain doesn't necessitate raising your bathroom floor, preserving the sleek aesthetics of your space.

How does the Invisible Drain prevent mold and bacteria buildup?
The Invisible Drain is designed to resist mold, mildew, and bacteria from the inside out. Made from high-density polyurethane and coated with polyurea, it won’t absorb moisture. The entire system is pre-waterproofed and thermo-sealed to prevent water from penetrating underneath or around the drain. Plus, its pre-sloped V-channel ensures fast drainage, eliminating stagnant water. With no exposed grates, grout lines, or hidden cavities where moisture and soap scum can collect, the result is a clean, hygienic, and low-maintenance shower solution.

What else do I need to buy for installation?
The Invisible Square Drain kit includes everything you need to install the drain, such as the square drain itself, drain body, 32 sq ft of Superdry Waterproofing, and a cleaning/lifting key. If you’re installing a curbless shower, we recommend adding Superdry waterproofing for the rest of the shower floor, walls, and any adjacent wet zones for complete moisture protection.

What is the Invisible Drain made of?
It’s constructed from high-performance polyurethane coated with polyurea, making it exceptionally durable and waterproof. With a compressive strength of 290 psi, it's so strong you could drive a car over it without causing damage! It is incredibly strong and lightweight, making it the ideal drainage system.

How can I clean the Invisible Drain and can I access the outlet?
Yes. The included lifting key allows you to easily remove the tile insert and access the drain base and outlet for maintenance. Simply lift, clean, and reset the tiles—no tools or grout removal required.

What kind of tiles can I use?
We recommend using porcelain or ceramic large-format tiles for the best performance and finish. These materials are highly durable, non-porous, and easy to maintain. You can choose any tile style as long as it’s large enough to cover the square drain—this is essential for achieving a seamless, invisible look.

Natural stone is not recommended, as it is porous and more prone to water absorption, which can lead to staining, warping, or mold over time.

Is the Invisible Square Drain compatible with a traditional shower with a curb?
Absolutely. For those who prefer a more conventional shower design with a curb, we offer prefabricated curbs, simplifying the installation process while maintaining the aesthetic and functional benefits of the drain.
