Narrow & Slim Towel Rail Options Explained
If you’re shopping for a narrow towel radiator or slim towel rail for a small bathroom, ensuite, or cloakroom, you may be wondering: is a 300mm wide towel radiator really narrow, or are there even slimmer options available?
Is a 300mm Wide Towel Radiator Considered Narrow?
Yes. A 300mm wide black towel radiator is classed as a narrow towel radiator. At just 30cm wide, it is significantly slimmer than standard towel radiators, which typically measure 400mm to 600mm wide.
A 300mm towel rail is a popular choice for:
-
Small bathrooms and ensuites
-
Cloakrooms and WC spaces
-
Tight wall areas next to doors or windows
-
Customers looking for a space-saving towel radiator
Despite the slim width, many 300mm towel radiators are available in taller designs to maintain good heat output and towel-drying performance.

Are There Narrower Towel Radiators Than 300mm?
Yes. If space is extremely limited, you can also buy ultra-narrow towel rails in widths such as:
-
200mm towel radiators
-
250mm narrow towel radiators
These are among the slimmest towel radiators available and are designed for walls where a 300mm unit will not fit.
200–250mm Towel Rails: What to Expect
While very narrow towel rails can solve tight space issues, they do come with limitations.
Best suited for:
-
Very small bathrooms or cloakrooms
-
Limited wall width
-
Hanging a single towel
For this reason, ultra-slim towel rails are usually chosen when wall space is the main constraint.

Why a 300mm Towel Radiator Is Often the Best Choice
For most customers, a 300mm wide towel radiator offers the best balance between compact size and everyday usability. Compared to 200–250mm models, it provides:
-
More space for towels
-
Better heat output
-
A wider range of heights, finishes, and styles
If your wall width is limited but you have vertical space, a tall 300mm towel radiator is an excellent solution.
