Bathroom Butler Cubic Collection
Cubic Heated Towel Rails
Every product here is a heated towel rail. Nine are listed, all Cubic, all straight and wall mounted, all built in 304 stainless steel with a squared profile. Two sizes of 6 bar rail are listed, at 530mm and 650mm, plus an 8 bar rail at 650mm. Finishes are polished stainless steel and matt black. Every rail carries either the PTSelect switch or the TDC timer, and that choice matters more day to day than the size.
PTSelect or TDC
PTSelect stands for Personal Temperature Selection, a dial built into the rail itself. Turning it right past an audible click switches the rail on and turning it left switches it off, while turning it further raises or lowers the power setting between a minimum of 40 percent and full output. A light shows where the setting sits. It suits a household that switches the rail on and off by hand.
TDC stands for Total Digital Control, a programmable timer built into the rail, with four on and off programmes across a 24 hour cycle, four modes covering automatic running, quick run, always on and always off, a 24 hour clock, a screen lock and temperature adjustment from 30 percent up to full. If your mornings and evenings run to a pattern, TDC heats the rail around them rather than all day. If they do not, PTSelect is less fussy.
Sizing a Cubic rail
The number in the title is the rail width, not the wall space it needs. A 530mm rail wants roughly 600mm of clear wall and a 650mm rail roughly 700mm, so measure the gap between a door, a screen or a corner first. The 6 bar rails are the shorter ones. The 8 bar is noticeably taller in the same 650mm width, and is the one to fit if more than one bath towel goes on it.
Installation and ratings
Bathroom Butler rates its heated rails IPX5 and states they are certified for bathroom zones 1, 2 and 3, which includes above a bath. They use dry element heating with no fluid inside, and the maker states exposed surfaces stay below 55 degrees, tested to IEC 60335-1 and IEC 60335-2-43. You can mount one yourself using the supplied template and 700mm of cable, but in South Africa a registered electrical wireman must make the connection to the mains, through an isolator.
