Now, this tip might not necessarily be meant for the bathroom itself, but it certainly applies to the bathroom. Pipe lagging (insulating your water pipes with foam tubes) can keep the water inside your pipes for much longer, both protecting the pipes against the cold and keeping the water inside hotter for much longer. You'll feel the benefits when taking a hot shower to warm yourself up. With these tips in mind, you're not just protecting yourself against the cold, you're turning your home into a winter haven. It can have a cosy aesthetic to it if you so wish...once you have the right temperature to really appreciate it!
