What if my Toilet isn't a TOTO Toilet? Will the Washlet still fit?
On a standard Toilet with no curves between the seat and tank, all you need is two inches of room
past the mounting bolts.
Washlet seats
For more precise Dimensions, see the dimensions chart below.
To ensure a proper Washlet fit on your current model, you can also use a box and ruler to check size and position.
*Note: You will need to remove your current seat to check fit.
