Every product category develops a dialect, and by the time you're comparing your third smart toilet, you're expected to be fluent in it. You shouldn't have to be. Here is every term you're likely to meet on a spec sheet — ours or anyone's — translated into plain English. Keep it open in another tab while you use the model comparison; that's what it's for.
The shapes
- Wall-hung. The toilet mounts to a frame concealed in or against the wall and floats clear of the floor. The most architectural silhouette, and the floor beneath mops in one pass. Needs the frame planned in — see wall-hung versus floor-standing.
- Floor-standing. The toilet stands on the floor like the one you grew up with, no frame required — the straightforward swap in an existing bathroom.
- Back-to-wall. A floor-standing unit whose rear sits flush against the wall in one clean line, with no gap collecting dust behind. Worth checking on any floor-standing model — it's a detail your eye reads even when you don't name it.
- Concealed frame. The steel skeleton inside the wall that carries a wall-hung toilet. Fitted and pressure-tested at first fix, then tiled over; your installer sets the seat height on it, which is why wall-hung models suit anyone with a preferred height.
The washing
- Bidet wash / spray wand. The heart of the machine: a wand extends, washes with warm water — temperature and pressure adjustable — then retracts. It rinses itself before and after every use.
- Cleaning modes. The wash patterns — position, focus, and gentler settings among them. More modes mean finer tailoring, not complexity; you'll settle on yours within a week.
- Massage wash. A mode that varies the water rhythmically rather than holding one steady stream. Found on our Signature models.
- Child setting. A gentler, pre-tempered wash for small users — lighter pressure, milder warmth.
- Bubble Shield wash. A layer of fine foam laid onto the bowl before use — it quiets the sound of use and helps the bowl rinse clean. On every model except Origin and Alto.
- Warm-air drying. The gentle dryer that follows the wash and mostly retires the paper. Standard on every Tresani.
The intelligence
- Auto open/close lid. The lid lifts as you approach and closes after you — the feature that makes the whole object feel considered.
- Off-seat (auto) flush. Flushes itself when you stand. With the foot-operated flush below, it means the toilet can be used entirely hands-free.
- Foot-operated flush. A low-level control you work with your foot — no hands involved. Depending on the model it is a push button, an infrared sensor, or a sensor hidden within the ceramic itself; on our wall-hung models it is a sensor underneath the pan.
- Smart flush. The unit judges the flush needed rather than spending a full one every time. Found on our top-tier models.
- Smart temperature. Seat and water warmth that adjust to conditions rather than holding one fixed setting.
- User memory. The toilet remembers each person's preferred settings and serves them without being asked. Currently unique to Elevare in our range.
- Voice control. Spoken commands to the unit itself — found on Nexus and Axia.
- IR care lamp. An infrared lamp built into the unit — a gentle warmth feature on Alto, Halo and Elevare.
- Night light. A soft glow that spares you the ceiling light at 3am. Standard across the range.
The housekeeping
- UV sterilisation. Ultraviolet light sanitises between uses — hygiene that happens while nobody's in the room.
- Self-cleaning wand. See above; the component you'd least like to clean is the one that cleans itself.
- Built-in perfume. A subtle fragrance released after use, and the deodoriser on our range. On every model except Origin and Alto.
- Anti-bacterial seating. Seat material that resists bacterial growth between cleans.
- Soft-close. The seat and lid lower themselves silently — no slam, ever.
The plumbing and power
- Built-in water tank. The reservoir inside the unit that powers a full flush regardless of your mains pressure — the feature that makes Japanese-style toilets effortless in British homes. No separate cistern to box in.
- Instant heating. Water warmed on demand rather than stored hot — endless warm washes, modest running costs.
- Fused spur. The fixed, protected electrical connection a smart toilet requires instead of a plug socket — fitted by a qualified electrician.
- Backup battery. Up to fifty flushes when the power's out. The toilet never stops being a toilet.
