Heated towel rails sit between a standard radiator and a bathroom accessory, giving you somewhere to dry towels while adding background heat. Flomasta is Screwfix’s own-brand range, competing with other budget-friendly towel radiators you’d fit in a cloakroom, en suite, or family bathroom where space is tight. These sizes cover common wall gaps, so you can often replace an older rail without moving pipework.

Which size makes sense for your bathroom?

The BTU figure is the useful bit, it tells you how much heat the rail can put into the room. Go larger if the bathroom is draughty, has an outside wall, or you want quicker warm-up. Smaller outputs can still work well in compact rooms where the main goal is warm towels rather than heating the whole space.

  • 800 x 500mm: 1238BTU, better for small cloakrooms
  • 1200 x 450mm: 1672BTU, a taller option where wall width is limited
  • 1200 x 500mm: 1815BTU, more heat for bigger bathrooms
