Look at the radiator height and width and match them to the wall space and the room size, popular towel rails come in 800 x 500mm, 1200 x 500mm and 1600 x 500mm. An 800 x 500mm rail suits a small en-suite or cloakroom, a 1200 x 500mm is a good fit for a standard family bathroom, and a 1600 x 500mm gives more towel drying space in a larger bathroom. Also think about vertical models such as 1800 x 540mm if you have narrow wall space but need more heat and hanging area. Finally, if you need room-heating as well as towel warming, look at panel radiators (Type 11, 21 or 22) because their panels and convectors increase heat output.

Heated towel rails, like square bar, Tuscan round bar or E-style, are primarily made for drying and warming towels and are sized for bathrooms; examples on offer include 1200 x 500mm and 1600 x 500mm models. Designer radiators, such as vertical aluminium or panel types (the Lambourne 1800 x 540mm or K2 Type 22 600 x 1000mm), are built to deliver more space heating and become a visual focal point. If your priority is dry, warm towels, a square bar rail is ideal; if you need to heat a larger room as well, pick a panel or vertical designer radiator.

Polished stainless steel and chrome finishes resist corrosion and are low-maintenance for humid bathrooms, while matt and powder-coated finishes such as matt black or anthracite offer a durable contemporary look but may show watermarks more readily. Brushed brass gives a warm, luxury feel but needs gentle cleaning to keep its tone. For a busy family bathroom, polished stainless steel or chrome is usually the most forgiving choice.

Valve type and size determine both flow control and aesthetics, 15mm thermostatic angled valves, corner valves and designer angled valves are available in finishes to match the radiator, such as brushed brass, chrome or matt black. Use an angled valve where pipework comes from the floor and a corner valve for pipes in the wall corner; matching a designer valve in the same finish creates a neat, integrated look. pair a 1200 x 500mm matt black square bar rail with matt black designer thermostatic angled valves for a seamless finish.

Yes, there are electric models such as the Kennet 1200 x 500mm electric heated towel radiator that run independently of a central heating system. Electric rails are ideal in cottages, extensions or bathrooms where you want heat on demand without firing the whole central heating. If you want both options, you can also choose hydronic towel rails or check for dual-fuel versions where available.
