Why Toto Parts Ensure Lasting Reliability, System Compatibility, and Long-Term Efficiency in Your Bathroom Fixtures

Toto replacement parts are built with the same meticulous precision as the brand’s original fixtures. Whether you’re maintaining a high-efficiency Neorest toilet, repairing a touchless faucet, or replacing an under-sink valve, using original parts is the only way to ensure your Toto product works as intended. These parts are designed for seamless fit and finish, meaning no guesswork or modifications during installation. They are factory-tested for performance under water pressure, thermal stress, and extended use.

Each Toto part serves a specific role. Components like brass drains maintain watertight integrity and resist corrosion. Electronic controllers power motion-activated faucets and thermostatic controls. Balancing valves regulate hot and cold water pressure to prevent scalding. LED kits bring Neorest toilets back to their original brilliance, including lighting and seat sensor functionality. Every part is backed by Toto’s legacy of precision engineering and designed to uphold EPA WaterSense or ADA compliance where applicable.

Whether you’re replacing a shower knob, upgrading a console frame, or sourcing parts for a commercial restroom retrofit, we make it easy. At Kitchen & Bath Authority, we carry every Toto part in stock—listed with specs, finish options, and product compatibility notes—so you can shop with confidence. Whether your project is urgent or planned, you can count on us for fast delivery, accurate support, and guaranteed Toto authenticity.


Toto Touchless Faucet Controllers

Toto touchless faucet controllers are the brains behind your smart faucet system. These units regulate flow timing, sensor range, and water temperature. Models with integrated heaters provide warm water on demand for residential and commercial settings. They are essential for restoring full function to Toto EcoPower or Libella series faucets, especially in healthcare, restaurant, or ADA-compliant environments. Built to resist water damage and electrical interference, these controllers are plug-and-play compatible with their paired faucet lines.


Toto Shower Knobs and Controls

Toto shower knobs are available as direct replacements for thermostatic or pressure-balanced valve trims. These knobs control temperature or flow and are essential for daily use. Made from solid brass or zinc alloy, they are plated in durable finishes like polished chrome to match Toto’s wider line of fixtures. Easy to install and maintain, they’re perfect for restoring shower function in homes, gyms, or hotel bathrooms.


Toto Brass Drains and Waste Assemblies

Toto brass drains provide long-lasting water-tightness for lavatories, tubs, and other below-floor installations. With direct push operation, these drains simplify waste control and are fully compatible with Toto sink and tub systems. Brass construction offers superior corrosion resistance, especially in areas with hard water. Polished finishes blend with existing fixture trim for a seamless appearance.


Toto Pressure Balancing Valves

Toto pressure balancing valves protect users from sudden temperature shifts by maintaining consistent hot/cold ratios. These valves are crucial for safe shower operation in both residential and commercial plumbing. Designed for wall installation, they support behind-the-wall systems and include inlet ports for hot and cold lines. Compatible with a wide range of Toto trims and handles, they ensure code compliance and safe water mixing.


Toto Neorest LED Covers and Kits

Toto Neorest LED replacement kits restore lighting, lid controls, and internal sensors on Toto’s luxury Neorest smart toilets. These covers house LEDs that illuminate bowl edges and seats during night use. The kit includes everything required for a full-service replacement, including the lid, wiring harness, and driver board. Ideal for maintaining comfort and technology consistency in high-end homes and executive suites.


Toto Console & Lavatory Support Frames

The Toto console frame for Lloyd sink provides structural support and visual appeal beneath semi-recessed and wall-hung lavatories. This metal console adds elegance to exposed sink installations while supporting weight and allowing for ADA-compliant leg clearance. It’s perfect for boutique hotels, modern home bathrooms, and upscale commercial spaces where visible support needs to be stylish and functional.
