Optimal bathroom size: Key considerations for a standard space

Whether designing a small or spacious bathroom, ensure the room adheres to the specific dimensions. So you will have an efficient and comfortable bathroom space. Hence, you must plan for the same at the construction stage. A standard guest bathroom includes a sink and a commode, which request about 20 square feet (sqft) of space. A medium-sized bathroom will need about 30-40 sqft to accommodate a sink, commode, and shower area, while a full-sized bathroom with all these elements and a bathtub requires an area of 50 sqft.

When constructing a bathroom, consider certain factors:

• A place for the sanitaryware, fixtures and bathroom accessories, concealed plumbing and electrical wiring. For example, bathtubs are available in various designs, shapes and sizes. Select a design that is perfect for your bathroom
• Width of the bathroom door: The door must swing open into the room and not hit the commode or vanity
• Position of various accessories: Make sure to cross-check them before you drill permanent holes to fix them

Designing a functional bathroom: Maximising utility within a standard size

A poorly designed bathroom can pose problems and affect your daily routine. Thus, you must consider a few important points that will help you create a functional bathroom.

• Lighting is crucial for a bathroom space; install windows to allow natural light. Besides, you will need additional light above the vanity to illuminate the space in front of the mirror.
• Choose low-maintenance materials, which also add beauty to the space. For example, natural stones can be used for flooring and wall covering.
• An in-built wall shelf will be a space-saving solution for your bathroom. This will provide you with additional floor space to accommodate your shower or bathtub.
• Include extra wall shelves if required instead of relying solely on vanity storage.
