Alto
ALTO
The essentials, elevated.
Alto takes everything that defines a Tresani — the warm-water cleanse, the heated seat, the quiet intelligence that opens to meet you — and lifts it off the floor. Wall-hung on a concealed frame, it leaves clean, uninterrupted lines and an open expanse of floor beneath, so the space reads calmer, lighter and far simpler to keep pristine.
The ritual is effortless. Approach, and the lid rises; the seat is already warm. A self-cleaning nozzle delivers a wash you control by temperature and pressure, followed by gentle warm-air drying — the everyday comfort that has been standard across Japan for decades, rendered here in Tresani's restrained, design-led language.
Beneath the simplicity sits genuine engineering: instant heating for endless warm water, UV sterilisation that keeps the nozzle hygienic between uses, an infrared care lamp, and a built-in water tank that guarantees a full, confident flush even in low-pressure homes.
Entry to the Tresani range asks for no compromise. Alto is proof that the essential can still feel exceptional.

Product details
These FAQs provide general guidance for Tresani customers considering smart toilets. Always consult the manufacturer’s documentation for specific installation, maintenance and safety instructions, and feel free to reach out to Tresani for personalised assistance.
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
