Square valves are the perfect addition to compliment a square style towel rail. Choose between straight or angled valves depending on the look you want to achieve in your new bathroom. Straight valves will allow installation in exactly the same way as a radiator, the pipes will come up through the bathroom floor and connect with the towel rail to create a straight look. Angled valves require the pipes to be hidden within the bathroom wall, the plumbing will then protrude from the wall and the valves will meet perfectly, which creates a stunning floating effect.
