Nick Duggan advises readers on heating for a bathroom renovation

“When it comes to renovating your bathroom, the towel rail might seem like a small detail but it’s one that makes a big difference. It’s not just about choosing something that looks beautiful on the wall (though that’s important too); it’s also about creating a space that feels warm, cosy and comfortable every day. To get it right, start with your BTU (British Thermal Unit) calculation. This handy number tells you exactly how much heat your room needs to stay toasty, especially on chilly mornings. Things like the size of the room, window area, how well it’s insulated and whether it’s on the ground or upper floor all come into play. Once you know your BTU, you can find a towel rail that delivers the heat you need while adding a stylish, design-led touch to your space.”
