We use them every day, often without even thinking, but have you ever paused to consider what a bathroom really is and why it matters so much? Whether you’re planning a renovation, designing a new home, or just curious, understanding the purpose and variety of bathrooms can help you make the best choice for your space.

Why Do We Need Bathrooms?

At its core, a bathroom is a private space designed for personal hygiene. But it’s so much more than that. Bathrooms play a vital role in our daily routines – helping us feel clean, relaxed, and ready to face the day. From brushing our teeth to taking a long soak in the bath, the bathroom is a place where self-care and comfort meet.

What Is the History of the Bathroom?

Bathrooms have evolved dramatically over the centuries. Ancient civilisations like the Romans had public and private bathing spaces.
