Buying Guide
One-Piece vs Wall-Hung
One-piece floor-mounted toilets are easier to install and ideal for residential and standard hotel projects. Wall-hung models with concealed cisterns give a floor-clear silhouette and 590mm short projection — best for small powder rooms and luxury bathrooms.
Standard / Smart / Smart Pro
Standard tier covers core wash, dryer, and heated seat. Smart adds oscillating wash and auto-close flush. Smart Pro adds foot-sensor lid open and remote control — full hands-free operation for hotel and luxury residential projects.
Rough-In Distance: 300mm or 400mm
Confirm your project's wall-to-flange distance before specifying. Our one-piece toilets ship with both 300mm and 400mm fitting options. Wall-hung models use a fixed 180mm wall drain (concealed cistern frame).
Frequently Asked Questions
What is a smart bidet toilet?
A smart bidet toilet is a ceramic toilet with a built-in electronic bidet seat. Unlike an add-on bidet attachment, the wash nozzle, water heater, dryer, and controls are factory-integrated into one unit. LANGDENG's smart bidet toilets feature instant tankless water heating, adjustable rear and feminine wash, warm air dryer, heated seat, and night light — delivering a complete spa-grade bathroom experience.
Do smart bidet toilets need electricity?
Yes. Every smart bidet toilet requires a grounded 110-240V power outlet within 1.5m of the unit for the electronic seat, instant heater, dryer, and sensors. Power consumption is around 1300-1700W during heating, with standby below 5W. All LANGDENG models include emergency manual flush in case of power outage.
What is the difference between one-piece and wall-hung bidet toilets?
One-piece bidet toilets have a seamless monobloc ceramic body that sits on the floor — easier installation, lower cost, ideal for residential and standard hotel projects. Wall-hung toilets mount on the wall with a concealed cistern frame behind, giving a floor-clear silhouette ideal for small powder rooms and luxury bathrooms. Wall-hung uses 180mm wall drain; one-piece uses 300mm or 400mm floor drain.
How much water does a smart bidet toilet use?
All LANGDENG smart bidet toilets use 3L/4.5L dual flush — 3 liters for liquid waste, 4.5 liters for solid waste. This meets WaterSense (US), WELS (AU), and most EU water-efficiency labels. The rimless siphonic flush design ensures complete bowl cleaning at this low water volume.
Can I customize OEM/ODM specifications?
Yes. LANGDENG offers full OEM/ODM customization with MOQ 100 units (50 units for color or knob configuration only). Customizable items include color (white, black, matte custom colors), knob style, control panel logo, packaging branding, and feature configuration tier (Standard / Smart / Smart Pro). Tooling for new ceramic shapes is available with higher MOQ.
