TOTO Washlet+ toilets hide the hoses. Instead of seeing a T-adapter and hose next to the toilet, everything runs through the bowl and inside the wall carrier.
The THU859 kit makes this possible by:
- routing water inside the wall tank system
- splitting water to the Washlet seat
- providing a service shut-off valve accessible through the flush plate area
Without this kit, you would have to install a visible external tee and hose, which defeats the Washlet+ concealed look. Think of it as a hidden plumbing adapter that lets a Washlet+ wall-hung toilet get water without any visible hoses.

Frequently Asked Questions
• What if my order arrives damaged?
While we take great care in the packaging and handling of orders, we ask that customers inspect all shipments within 48 hours of delivery, and in the rare event that your order arrives damaged, please send us an email with a photo showing the damages (so we can file a claim with the carrier), and let us know whether you prefer a free replacement or a refund.
• Why do you ask for phone numbers during checkout?
Some shipping carriers, especially those handling freight, require a phone number to coordinate your delivery. We respect your privacy and guarantee that any information you provide will never be shared with third parties, except for shipping purposes.
The THU859 kit connects water supply to both the toilet tank system and the Washlet bidet seat while keeping the plumbing concealed inside the wall system.
It provides the correct shut-off valve, adapters, and connectors needed for a Washlet+ wall-hung installation.
