300mm Electric Towel Rail FAQs
A 300mm wide electric towel rail is the go-to choice when wall space is limited. Their slim profile fits neatly on narrow walls between standard stud centres, making them ideal for small ensuites, cloakrooms, and compact bathrooms — without sacrificing towel warming performance or style.
Yes — 300mm wide electric towel rails are one of the most popular choices for cloakrooms and small WCs. Their narrow footprint means they fit without dominating the space. We recommend a height of at least 800mm to maximise the number of bars and towel-warming capacity in a compact room.
Most 300mm electric towel rails range from 60W to 150W. At the current UK rate of 24.67p/kWh (from 1 April 2026), a 100W model costs around 2.5p per hour. Running it for 2 hours daily works out at approximately £1.80 per month — one of the most economical ways to keep towels warm and bathrooms comfortable.
Our 300mm electric towel rails are available with a choice of elements — standard (manual on/off), or thermostatic (IPX4, with temperature control). For timed scheduling, we recommend adding a separate fused spur timer switch (IP20 rated), which must be positioned outside the bathroom zones in accordance with BS 7671 wiring regulations.
Installation requires a qualified electrician or Part P certified installer to connect the heating element to a fused spur on your mains circuit. The rail itself wall-mounts on two brackets — exact spacing is specified in the product manual. In bathrooms, all electrical work must comply with BS 7671 and be notified to Building Control. Standard installation takes 1–2 hours.
