Maximizing Small Bathroom Space

If your bathroom falls within the average small bathroom square footage, don't despair. There are plenty of ways to make the most of your space.

Efficient Layout

Plan your layout to minimize wasted space. Consider using a corner sink, a shower with a seat (to save space from a separate bathtub), and a wall-mounted toilet to free up floor space.

Multifunctional Furniture

Choose furniture that serves multiple purposes, such as a vanity with built-in storage or a stool that can be used as a step stool or extra seating.

Light and Mirrors

Use light and mirrors to create the illusion of a larger space. A large mirror can reflect light and make the room feel more expansive.
