This size allows for a wider range of bathroom suite layouts and additional features like a shower enclosure or a freestanding bath.

Regardless of the size of your bathroom, there are always ways to make the most of the available space. Here are some tips to help you create a functional and stylish bathroom:

Maximize storage: Install wall-mounted cabinets, floating vanities, or shelving to keep your bathroom clutter-free and organized.
Use mirrors: Mirrors can make a small bathroom feel larger by reflecting light and creating the illusion of more space.
Consider a wet room: If you have a larger bathroom, converting it into a wet room can create a sleek, modern look and make the most of the available space.
