Measure First
After wall-mounting a 6.6L heater, an L-shaped space of 40-60cm wide × 25-35cm deep usually remains.
Three Zones
- Door back: adhesive hooks for towels and sprays.
- Bottom: narrow bins for refill bottles.
- 10cm above the heater: light spares only — keep 5cm clearance for heat dissipation.
Safety Lines
Keep 5cm around the unit clear and leave the leak sensor area empty.
