Aqualisa Lumi Electric Showers

Look at the three power options on offer, 8.5kW, 9.5kW and 10.5kW, and match them to how hot and how strong you want the spray. Higher kW delivers hotter water at a given flow, so 10.5kW is best if you like a fuller, hotter flow; 8.5kW is perfectly adequate for a small en‑suite or a modest mains supply. Also note the electrical cable guidance printed with each rating (for example 8.5kW can use 6mm² cable for runs up to 18m but needs 10mm² for 18–35m; 9.5kW and 10.5kW are listed as 10mm²). Those details tell you whether your property's electrical supply can support the model you want.

The Lumi range has an illuminated control panel with adjustable light levels so you can set bright, energising light for morning wakes or dimmer, softer light for late‑night showers. The lighting is built into the panel as a design feature, so it provides atmosphere rather than room illumination, useful as a gentle night‑time option that avoids switching on harsh overhead lights. You can tailor the level to suit your routine and mood.

Aqualisa offer the Lumi in chrome variations, including a mirror finish shown in the listings, so you can match contemporary chrome taps and fittings for a cohesive look. A mirror finish reflects light and helps make small bathrooms feel more spacious, while a standard chrome finish sits neatly with matte tiles or industrial accents. Think about whether you want the unit to blend in (chrome) or act as a reflective feature (mirror finish).

Yes, the choice of kW helps you match the Lumi to the room. An 8.5kW model is a good, economical option for a small en‑suite where you don't need a very high flow, while 9.5kW or 10.5kW give stronger performance for a main family bathroom where you favour a hotter, fuller spray. The design‑led finishes and mood lighting also add a high‑end touch whether the room is compact or larger.

The three models are the Lumi+ 8.5kW (LMEP8501), 9.5kW (LMEP9501) and 10.5kW (LMEP10501); the main difference is power, with prices on the site reflecting that range. If your priorities are economy and a modest shower flow, the 8.5kW model offers the lowest price point; if you want maximum performance the 10.5kW gives the hottest, most powerful flow. The right value comes down to how hot and strong you like your shower and whether your electrical supply can support the higher kW options.
