TOTO's exclusive Shape Memory Alloy (SMA) Thermostatic Mixing Valve, now available in select TOTO shower systems, features a nickel and titanium alloy coil that responds to temperature changes more quickly than traditional wax-type thermostatic mixing valves. The result is a more comfortable shower with benefits like:

• Outstanding anti-scald protection
• More power to quickly achieve and maintain your ideal temperature setting
• Durability for a lifetime of perfect performance (unlike conventional wax thermostatic mixing valves, the material and design of SMA prevents degradation in performance over time)
