What You'll Love

Redefine your bathroom experience with the Eridanus Piedmont Smart Toilet, featuring a sleek, skirted silhouette that effortlessly elevates any modern space. Available in two tailored configurations—a streamlined Basic model for essential comfort or a fully loaded Standard edition with advanced digital displays and bidet therapies—this fixture combines an adjustable heated seat with touchless, foot-sensor flushing to deliver exceptional hygiene and hands-free convenience.
Product Details
  • Intelligent Touchless Flushing (Both Models): Combines a pre-use bowl mist with a powerful, whisper-quiet siphonic flush that activates automatically upon standing or via a convenient foot sensor for a completely hands-free experience.
  • Personalized Heated Seat (Both Models): Features an ergonomically designed soft-close seat with smart sensors and adjustable temperature controls, providing welcoming warmth year-round and eliminating cold shocks during winter.
  • Customizable Bidet Cleansing (Standard Edition Only): Delivers instant-heating warm water with adjustable pressure, temperature, and specialized wash modes (rear, feminine, and mobile) for a tailored, highly hygienic clean.
  • Advanced Massage & Drying (Standard Edition Only): Upgrades your routine with exclusive ThermoSoothe (hot/cold contrast) and AquaPulse (pulsating) massage therapies, followed by a temperature-adjustable warm air dryer that reduces reliance on toilet paper.
  • Intuitive Controls & Display: The Basic model offers streamlined operation via a sleek side knob, while the Standard Edition adds a wall-mounted remote, an integrated LED lid display, and soothing ambient lighting.
  • Hygienic Self-Cleaning (Standard Edition Only): Automatically rinses the durable bidet nozzle before and after every use, maintaining optimal sanitary conditions without any manual scrubbing.
  • Night Light & Safety Systems (Both Models): Guides you safely in the dark with a soft-glow LED night light, backed by IPX4 waterproofing, low-voltage 12V operation, and a mechanical flush function ensuring usability during power outages.

Frequently Asked Questions

How can I track my shipment?

Once your order ships, a tracking number will be sent to the email address provided at checkout. You can use this number on the carrier’s website to monitor your delivery progress in real-time.
How long will it take to process my order?

Most orders are processed and ready for shipment within 1-2 business days. You will receive a confirmation email once your order has been placed and another once it has shipped.
Can I install these products myself?

While we provide comprehensive installation guides, we strongly recommend hiring a licensed professional plumber (and an electrician for smart toilets). Professional installation ensures your product functions correctly and keeps your warranty valid.
Do your smart toilets come with a warranty?

Absolutely. All our smart toilets come with a one year limited warranty covering the electronic components and the ceramic body. If you experience any technical issues, our US-based support team is here to help.
Are your vitreous china sinks scratch and stain-resistant?

Yes. Our sinks are crafted from high-quality vitreous china and fired at extreme temperatures. This creates a non-porous, high-gloss finish that is exceptionally resistant to scratches, acid, and staining, ensuring long-lasting beauty.
What should I do if my ceramic sink or toilet arrives damaged?

Please inspect your package immediately upon delivery. If you notice any cracks or damage, contact our support team within 48 hours with photos of the item and packaging. We will prioritize a free replacement or a full refund for you.
