FAQ

How does the Invisible Modular Drain prevent mold and bacteria buildup?
The Invisible Shower Tray 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 tray. 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 drainage solution.

Can you help me design a drain system that fits my outdoor space?
Yes! We offer two easy ways to help you create the perfect layout for your space.

You can use our virtual layout tool to design your own Invisible Drain system. Just select your space’s dimensions, and the tool will automatically suggest a layout that’s as close as possible to your measurements to ensure all components fit seamlessly within the space. It will also guide you in selecting the right pieces, including channels, corners, outlets, and end caps for a complete installation.

Prefer personal assistance? Our team is happy to help with a custom layout design based on your space. Just send us your dimensions and outlet placement to info@qm-us.com, and we’ll take care of the rest.

How many outlets do I need for proper drainage?
QM recommends one outlet every 72 inches (6 feet) to ensure optimal water evacuation. For custom layouts, our team or virtual tool can help you determine the ideal number and placement of outlets based on your specific design.

What is the Invisible Modular 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.

Is the Modular Outdoor Invisible Drain suitable for residential and commercial applications?
Yes, it's versatile enough for both residential settings like terraces and pools, as well as commercial spaces such as health and wellness centers and sports facilities.

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 maintenance is required for the Invisible Drain system?
Maintenance is minimal due to the self-cleaning design. However, we recommend occasional inspections to ensure the channels remain free of debris for optimal performance.

What are the advantages of the internal V-shaped slope?
The internal V-shaped slope allows for easy and fast water flow, effectively preventing water stagnation within the channel and ensuring efficient drainage throughout the system.
