    Hi Folks,
    Searches (google and here) haven't yielded definitive answers to my topic question above.
    I have a Geberit carrier 111.798.00.1 with a Toto Aquia wall hung attached to it.
    I'd like to add a Toto Washlet.

    From what I've read and what I see in my old construction pics and the Geberit install manual there is an inlet on the left side of the carrier for "Optional washlet water supply stop".

    That's about as far as I've gotten in research. There is no info on installation, what fittings are necessary, etc... My pics of the carrier don't show enough detail of that inlet and it's now sitting behind tile, greenboard and 1/2" ply backing. I'll to dig it out when I'm certain it can function for a washlet.

    How do I go about with fittings for this inlet that would mate with the Toto Washlet supply tube?
    Thank you in advance for all your help!

    I personally haven't installed a washlet on a wall hung toilet. But one of our projects early in pandemic did have that setup of geberit carrier and washlet. I'll ask who did the work and how they connected the two. The part in the wall that supplies water to the washlet outlet seems weird to me.

    242.886.00.1

    seems like there needs to be a threaded fitting to attatch to.

    TOTO uses this shutoff

    1/2" threaded nipple for this to the wall.

    This one somebody had stubbed out with PEX, I had to adapt that.

    Okaay - Just spoke with Geberit and they said this setup would need a Bidet Seat Kit.
    Part numbers 249.801.00.1 and 243.173.00.1 (hoses and shutoffs).
    They also pdf'd 2 instruction files for the install. I would have uploaded them but this site says they are too big. If anybody is wondering, just give Geberit technical dept. a call and they will send to you. I haven't yet had a chance to review the literature so can't vouch for their instructions. They assured me that it would fit the Toto Washlet.
    Thank you guys for the help so far though, I'm hopeful there is a solution as they claim.

    Terry, does the geberit carrier have a supply pipe in the wall like the toto carrier does? I see they have what they call a conduit.. but I'm not sure if that supplies water or if its meant to feed a water line through.. sometimes things get lost in translation from the germans.

    From the geberit part posted by Lily, it looks like it is indeed a conduit to slide their braided hose down through to a bidet. Looks like it has a splitter that connects after the shut off.

    Always funny when they produce videos with some guy in slacks and pattent leather shoes on holding a wrench like it a fine glass of Merlot.

    OMG!! At the end of the video he's caulking the toilet to the wall with Liquid Nails!! Yikes!

    After studying Geberit's unappealing images of various shut-off installs, I've decided to go back to Plan A and supply the washlet from the sink next to the toilet. The shroud beneath the sink will hide the fittings. All one will see is a white tube mysteriously disappear behind the shroud. But it's nice to know Geberit gives its consumers some options. Thanks everyone for chiming in.

    Help with my Plan A - supply Toto Washlet from sink cold water supply.
    Was going to use GenieBidet's 3/8 x 3/8 x 1/2 T connector.
    I'm reading that the Washlet inlet hose's 1/2" O-ring contraption inside the compression nut (is that what it's called?) is proprietary to Toto. This O-ring will mate with their T connector THU6234 (packaged with washlet).
    Genie Bidet's 1/2" receiver is too shallow to work with Toto's inlet hose.

    Is this true? If so, what other solutions are there?
    Thank you!

    UPDATE: Attached is my workaround using both Genie Bidet and Toto's T connectors. I'd love feedback on this setup. TIA!
