Why this model

Glass panel in a 150 mm body, at 3.5 kW

The compact single-power unit — for the walls where the full-height glass models will not go.

White or black glass

White or black glass

Both panel colours are held in stock. Custom colour, pattern and logo follow the usual 100-piece minimum, with an artwork proof first.

3.5 kW, two seconds

3.5 kW, two seconds

The stainless steel cup element heats the water as it passes, so a shower reaches temperature in about two seconds with nothing stored to run cold.

Touch control, LED readout

Touch control, LED readout

A flat glass touch strip sets the temperature and the LED shows it live — nothing to mis-set and fewer support questions.

150 mm wide, 1.8 kg

150 mm wide, 1.8 kg

Where a mirror, a shelf or a shower rail leaves no room for a full-height unit, this one still fits without moving the fixture.

MOQ 1 pc

The sample price difference comes back

A single unit is charged above the bulk price, because of one-off handling and air freight. Place a bulk order for the same model within 30 days of receiving the sample and we refund the difference.

Our four price tiers — 10–99 / 100–999 / 1,000–9,999 / 10,000+ pcs — are counted cumulatively over the 30 days after you receive the goods. Reach a higher tier and we refund the difference on the units you have already shipped.
