Bathroom Butler heated towel rails are a breeze to install, they come with their own installation template that shows where you need to drill your holes prior to mounting and have measurements. All you need is pre-installed electric point which your electrician can provide. If you’ve got a knack for DIY, you could easily mount it on the wall yourself. Allow for the electrical point before putting any tiles on the wall and check local electrical codes prior to connecting to live wiring.
