Without the heated flooring, the bathrooms are pretty cold, so it's actually a handy thing to have in the flooring and it's also comforting to start your day getting your toes toasty from a warm floor.
Under the bathroom tiling lies a mat with coils, these coils are what heats the floor. It's a good investment as it doesn't take up any space unlike a heater in the bathroom as it's concealed under the flooring, it can be used to heat the entire bathroom and it doesn't use much power.
|Not that bathroom floors are particularly nice to look at or anything, but here's ours.|
Warm and toasty.
