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.
