Best Shower Styles for Small Bathrooms

The style of the shower plays a huge role in making a small bathroom design comfortable. Choosing the right shower head can make the entire bathroom appear much larger.

What is the best shower style for a small bathroom?

The best solution for a small bathroom is a shower design that takes up less space and visually reflects light. The most effective styles are discussed below:

• Corner-Fit Shower: This is the number one solution for small bathrooms. A square, diamond or quarter-circle shaped corner shower enclosure saves the most space when placed in the corner of the bathroom. This is a master stroke for your small bathroom designs with a shower and toilet.
• Walk-in Shower: While it can be challenging to fit a full walk-in shower into a small bathroom, it is possible with frameless glass walls. Frameless glass walls create visual space because they are unobstructed and allow light to flow through easily. Data shows that glass doors can make a bathroom look up to 30% larger.
• Curved or Sliding Doors: Traditional swing doors take up space to open in or out. But using curved or sliding shower doors can save that extra space. This is a great space-saving shower trick.

Space-saving fixtures and smart storage

Space-saving fixtures multiply the functionality and style of small bathrooms. They not only save space but also help in maintaining cleanliness.

Smart Fixtures & Storage Ideas:

• Floating Vanities: These wall-hung vanities are slightly above the floor, allowing the floor to visually continue. It makes the bathroom feel very open. A 24-inch (61 cm) single-sink floating vanity is adequate for smaller spaces.
• Wall-Hung Toilet: These wall hung toilets can save up to 10 inches (25 cm) of space compared to regular toilets because their tanks are hidden. This also makes them easier to clean and gives the bathroom a modern look.
• Toilet-Sink Combo:
• Is a toilet with sink on top better? Yes, a toilet sink combo is a great solution for small bathrooms. This fixture recycles the water used during hand washing into the toilet flushing tank, which not only saves space, but also saves water (can increase water efficiency by up to 50%).
• Recessed Shelves & Niches: It's a great one-bathroom storage idea for small space. No extra space is wasted by making a shelf in the shower wall or in the wall above the toilet.
• Smart Storage Hacks: Mirror cabinets and over-toilet shelving utilize vertical space. It's your small bathroom designs with shower and toilet provides additional storage required for this.

Design techniques to make bathrooms look bigger

There are some great visual tricks to make your bathroom look much larger and more luxurious than it actually is.

Design Tricks to Make Small Bathrooms Look Bigger:

• Light and Bright Colors: Light colors, such as white, off-white, and pale gray, reflect light. This makes the walls appear to recede. For a luxury small bathroom design, use a monochromatic scheme of light colors in the tiles and wall colors..
• Frameless Glass & Mirrors: This is the most effective strategy. A frameless glass enclosure (discussed in Section 4) and using a large, frameless mirror adds depth and light to the bathroom. A full-length mirror can double the space.
• Patterned Tiles: Use large-format tiles instead of small tiles, as fewer grout lines make the space look unobstructed. Using tiles with a bright pattern on the floor will draw the eye down to the floor and make the bathroom look larger. Vertical stripes or vertically placed subway tiles will help to make the ceiling appear higher.

If you follow these strategies, your tile ideas for a small bathroom will become much more interesting.
