Slim Design — 115 mm
At just 115 mm thick, the NS2401 is one of the slimmest smart seats on the market. Korean competitors average 145 mm — this fits more toilet shapes and looks cleaner.
90° Rotatable Water Inlet
Rotates for flexible routing — a critical advantage for North American installations where pipe configurations vary widely.
Side Silent Pads
Rubber pads on the sides of the seat accommodate narrow‑edge toilets — no overhang, no wobble.
Frequently Asked Questions
What is the MOQ for OEM orders?
Through our platform-sharing model, you can start with as few as 100 units for a custom enclosure design. Standard configurations are available at lower quantities for sample orders. Contact us for a specific quotation based on your requirements.
What certifications does the product carry?
The product is certified to ETL, cETL, and FCC for the North American market. Every platform ships with a complete technical file including test reports and declarations of conformity.
How long does OEM customisation take?
Customisation typically takes 2–4 months from design freeze to first samples, depending on the extent of changes. The shared internal architecture means electrical and water-path certification does not need to be repeated for enclosure-only changes.
Can I visit the factory before placing an order?
Yes. We welcome factory visits in Ningbo, China. You can inspect the production line, testing laboratory, and meet the engineering team. Schedule a visit — we usually confirm within one business day.
Does this seat fit my existing toilet?
NS2401 is designed for standard North American round and elongated bowls with a slim 115 mm profile. Send us your bowl dimensions (bolt-hole spacing and bowl length) and we confirm compatibility before you commit.
What power supply does it need?
A standard 120 V GFCI-protected outlet within reach of the power cord (about 1 m). Never use an extension cord or multi-socket adapter — a dedicated outlet is the recommended practice for bathroom appliances.
