ORIGIN
The essentials, done properly.
Origin is the purest expression of Tresani: a floor-standing smart toilet stripped back to the things you'll use every day. A warm-water cleanse, a gently heated seat, a lid that opens as you approach and closes behind you — nothing superfluous, nothing missing.
It looks after itself. The nozzle self-cleans and sterilises under UV between uses, instant heating means the warm water never runs out, and a built-in tank guarantees a full, confident flush even where mains pressure is low. A soft night light makes the small hours effortless.
This is the most accessible way into the range, and it asks for no apology. Origin proves that "entry-level" and "beautifully made" belong in the same sentence.

CAN YOU USE TOILET PAPER IN A SMART TOILET?
Yes — though you'll barely need it. A Tresani cleanses with a warm-water bidet wash (adjustable for temperature and pressure), then a warm-air dryer, so water does the work instead of paper. Keep a roll for guests if you like, but you'll use far less than before — and a water clean is gentler and more thorough than dry paper alone.
DO I NEED A PROFESSIONAL TO INSTALL IT?
Yes — a qualified plumber and electrician. Each Tresani needs a nearby water supply, a waste outlet and a fused electrical spur (a standard plug socket isn't enough). Installation usually takes a couple of hours
WILL IT WORK WITH MY WATER PRESSURE?
Yes. Every Tresani has a built-in water tank, so you get a full, powerful flush and a steady warm-water wash even in low-pressure homes.
WHAT HAPPENS IN A POWER CUT?
It keeps working. A backup battery gives up to 50 flushes, and power-off flushing means you're never caught short — even with the electricity down.
HOW MUCH DOES IT COST TO RUN?
Around £50–£80 a year in electricity for a household of four — often offset by what you save on toilet roll
