NOVA

Nova is a newer brand with features similar to TOTO.  A nice benefit of Nova's remote controls is that they use radio waves rather than infrared.  If you have a very full bathroom, towels, mats, and other objects that can block the infrared, then having a remote control with radio waves is a good alternative.

Another great feature of NOVA, is the enema feature.  While TOTO has a strong spray, NOVA's enema feature is designed to get you flowing.  Unlike many models, NOVA can also be controlled right from the seat with a knob on the right, rear side.
