If you are shopping for a bidet to complete your toilet, you know that the bidet will at least require a water connection. If you are opting for a bidet with a heated seat, hot water, air dryer, or other electric features, you will also need to plug your bidet into the wall.
Discovery DLS bidet seat by Bio Bidet
The Discovery DLS illustrated above shows the two exposed connections that the seat requires to function. They aren't necessarily in the way, but what if you could hide them entirely? Enter the Toto Washlet+.
Toto Legato toilet, topless to show the Washlet+ port
The Legato one piece toilet shown above is considered Washlet+ because it allows for the water and electric lines of a compatible Washlet bidet seat to be threaded through the hole and out the back of the toilet, instead of outwards and around the side of the toilet. I say "compatible Washlet bidet seat" because not all Washlet bidet seats are made to utilize this hidden setup. The list below shows which Toto bidet seats come in Washlet+ variations.
While online, you can tell these Washlet+ seats apart from their mostly identical twins by the "T40" that will be at the end of their SKU number. Is it possible to use a non-Washlet+ seat on a Washlet+ toilet? Yes, it will fit, however you will likely have issues if you attempt to run the connections through the toilet. A non-Washlet+ seat orients the ports to go out and around the toilet whereas a Washlet+ seat goes down and through the hole shown above.
In our shop you will see bidet toilet combos such as the Aquia IV with K300 bidet toilet combo that is not a Washlet+ unit because the Toto K300 is not produced in a Washlet+ compatible version. Therefore, it is paired with a Aquia IV that does not have a Washlet+ port.
Whether you are going for the seamless look of a Washlet+ system, or do not mind a hose and wire sticking out of your toilet, you now know what the Washlet+ badge means. To see the Washlet+ systems we sell, click here for the Washlet+ collection.
