Create a Sink and Toilet Combo with Sink Twice's "Sink Smaller" for high efficiency toilets!

Wash your hands with the clean water, leaving the soapy water to clean your toilet when flushed! Sink Twice is a major water saver, leak detector and a space saver.

Our patent pending "fill cycle diversion" faucet is a significant leap ahead of our competition in water efficiency. The basin has plenty of room on the flat soap holder for foam soap containers and the drain is specifically designed to prevent splashes.

This smaller model measures 15.25" and is recommended for small toilets measuring 13" -  15.25" wide (measured with the lid off). If your tank is larger than 15.25", please carefully consider one of our larger models.

Sink Twice is designed to function best with Universal valves (i.e. Fluidmaster, Korky and common ball and valve combinations). FluidMaster 400A (or other Fluidmaster 400 series) is best if you need a valve. Sink Twice is compatible with gravity fed (not jet fed or tankless) toilets.  If you have a 1.6 GPF toilet, please either consider a SinkTwice original with or without the expander kit depending on tank size or buy our "Sink Again" model instead which best fits toilet tanks 17" -19.5" (measured with the lid off). For large rectangular tanks, you have two options - for rectangular tanks measuring 18" - 20" (measured with the lid off), please buy the "Sink Bigger" model. For tanks measuring 19.5" - 21" (measured with lid off) please buy the Sink Twice original model WITH its expander kit.
