  • The height of the TOTO Aquia IV is universal height, which is designed to be more comfortable for most adults when sitting and standing.

  • The difference between a TOTO Washlet and Washlet+ is that Washlet+ is made to pair with specific TOTO toilets so the cords and hoses stay hidden for a cleaner look.

  • You can know if a TOTO Washlet will fit your toilet by checking if you have an elongated bowl and the right mounting space behind the seat. Most TOTO models are designed to fit standard setups.
