This undermount sink repair kit is designed to reinforce and stabilise falling or loose sinks and basins in kitchens and bathrooms. It provides a reliable support system that helps prevent future sink failures, giving you peace of mind and long-term security.
Built with stainless steel tubes, a thickened high-quality metal base, and non-slip protective pads, this 2-bar sink support system can hold up to 225 kg. It delivers firm, long-lasting stability and can also be used to support fish tanks, shelves, cabinets, and more.
The adjustable design makes this sink bracket compatible with most square undermount sinks or basins used in kitchens and bathrooms. Before installation, simply measure the height from the bottom of the sink to the floor to ensure proper fit.
No drilling, no sink removal, and no plumbing disassembly needed. Installation is quick and straightforward. Note: Slight movement during setup is normal before installation, as there is no support point yet. Once properly installed under the sink, the structure becomes highly stable.
Beyond undermount sinks, this versatile support bracket can be used for shelves, cabinets, and heavy household items that require additional reinforcement. A practical solution for both repair and prevention.
