Terma aims to think differently when conceiving its towel rail designs and the Rolo Towel is no different with its super chunky 40mmk diameter bars creating a very sturdy looking towel rail design.. Manufactured from durable, low carbon mild steel. The Salt n Pepper colour from Terma has a matt, rough texture. Terma offers a 150x50mm colour chip of this finish should you wish to see the colour prior to purchase.. The oversized bars on Rolo Towel help offer increased heat outputs meaning this design will suffice if your towel rail is the only heat source in the bathroom..
