One-Piece Bidet Toilet
One-Piece Bidet Toilet — Smart, Skirted, Comfort Height
LANGDENG's one-piece bidet toilets pair a seamless skirted ceramic body with a fully integrated smart bidet. Standard comfort height seat (380mm), elongated bowl shape, and rimless siphonic dual flush at 3L/4.5L make them the workhorse one piece toilet for hotels and residential projects. Instant tankless heating powers rear, feminine, and oscillating wash with warm air dryer, heated seat, and night light. Rough-in distance 300mm or 400mm fits standard installations worldwide. Available in Standard, Smart, and Smart Pro tiers — higher tiers add auto-close flush and foot-sensor lid open.

Frequently Asked Questions
What rough-in distances do one-piece toilets support?
LANGDENG one-piece smart toilets ship with 300mm and 400mm rough-in options as standard, matching the most common floor-drain placements globally. Confirm your project's wall-to-flange distance before ordering. Custom rough-in is available with higher MOQ.
What is comfort height and why does it matter?
Comfort height refers to a taller seat height than the standard 380mm — typically 430–485mm. Our one-piece bidet toilets use 380mm comfort-height seats that meet ADA-friendly specifications and reduce knee strain for elderly users and tall adults. Standard for hospitality and aging-in-place projects.
Are one-piece toilets harder to install than two-piece?
Easier, actually. The bowl and tank ship as a single sealed ceramic unit, so there is no tank-to-bowl assembly or risk of joint leaks. Connect the supply line and floor flange, set in place. A trained plumber finishes in around 30 minutes.
What is the difference between Standard, Smart, and Smart Pro tiers?
Standard includes core wash, warm air dryer, and heated seat. Smart adds oscillating wash and auto-close flush. Smart Pro adds foot-sensor lid open, remote control, and customizable wash profiles — full hands-free operation for hotels and luxury residential. All three tiers share the same ceramic body.
Can I customize one-piece toilet colors and logos?
Yes. Full OEM/ODM customization is available with MOQ 100 units per model. Customizable items include matte color (white, black, charcoal, custom), knob style, control-panel branding, and packaging design. New ceramic-body tooling requires MOQ 500 plus a one-time tooling fee.
