Should you choose TOTO Legato or Nexus?
These two lines share more than they differ. Both are fully skirted with a concealed trapway, both use TORNADO FLUSH with CEFIONTECT glaze, both sit at universal ADA height and both take the same S2 through S7A WASHLET+ seats.
The first real difference is range. Legato is four models; Nexus is nineteen. More importantly, every Legato in stock comes with a washlet already fitted, so there is no way to buy a Legato as a plain toilet. If you want the bowl now and a bidet seat later, Nexus is the only option of the two.
Nexus also offers two-piece models and a 1G version at 1.0 gallons per flush. Legato is one-piece and 1.28 GPF across the board.
Where they do overlap, Legato is consistently cheaper. A one-piece with an S2 washlet is $1,488 as a Legato against $1,675 as a Nexus, a $187 difference. At S5, S7 and S7A the gap narrows to about $30, but it always runs the same way.
The look is the other consideration. Legato has a high-profile, angular tank with a light, contemporary feel. Nexus sits lower and reads a little softer. Neither is better; they suit different bathrooms and it is worth looking at photographs of both before deciding.
Choose Legato if you want a one-piece with a washlet fitted and you like the taller tank, since it will cost you less than the Nexus equivalent. Choose Nexus if you want a bare toilet, a two-piece, or the 1.0 GPF flush.
