For smart home fans, we have summarised the must-haves in our article TOP Smart Bathroom Ideas.

Corner Sinks and Toilets

Corner sinks are an excellent choice for tiny bathrooms, as they fit snugly into what would otherwise be unused space. Similarly, corner toilets have a triangular tank, allowing them to be installed in a corner, opening up more floor space. These fixtures can be pivotal in maximizing the layout of compact bathrooms.

Wall-Mounted Features

Utilizing the walls to mount features such as sinks, toilets, and storage cabinets keeps the floor clear and enhances the sense of space. This approach also simplifies cleaning; without pedestals or vanity units, maintaining a tidy bathroom becomes easier.

Compact Shower Designs

A well-designed compact shower can conserve space without sacrificing comfort. Enclosures with curved or angled doors maximize shower area while minimizing the amount taken from the rest of the bathroom. Opting for a sliding door rather than a hinged one can further save space.

Storage Solutions

Tiny house bathrooms require clever use of space. Efficient storage solutions can keep the area clutter-free and fully functional.

Built-In Cabinets

In a tiny house bathroom, built-in cabinets offer a seamless and space-saving storage option. They can be designed to fit into unusual spaces or corners, ensuring no area goes unused.

Over-Toilet Shelving

Over-toilet shelving utilizes the vertical space above the toilet for storage. Shelves or cabinets in this space can hold towels and toiletries, turning an otherwise empty area into a practical storage zone.

Hidden Drawers

For an uncluttered look, hidden drawers cleverly built into walls or under sinks provide out-of-sight storage. They maximize the available space without making the bathroom feel cramped.

Design and Aesthetics

When designing a tiny house bathroom, the selection of color schemes, lighting, mirrors, and decorative accents is crucial for creating an inviting and functional space.

Color Schemes

In tiny bathrooms, the right color scheme can make all the difference. Lighter colors can make the space feel larger and brighter. For instance, a monochromatic palette with varying shades of the same color can create a seamless look. Bathrooms with a modern and simple aesthetic can benefit from neutral colors, while adding a pop of color brings in personality without overwhelming the space.

Mirrors and Lighting

The strategic use of mirrors can transform a tiny bathroom. A large, frameless mirror not only serves a functional purpose but also reflects light, making the room appear more spacious. Oversized mirrors are particularly effective. Proper lighting complements mirrors well, enhancing the atmosphere and making the room feel more open. Use ambient lighting for a soft glow and task lighting for areas like above the vanity.

Decorative Accents

Decorative elements add character to any tiny bathroom. One can incorporate items such as chic shelving or unique hardware that doubles as decor. Industrial-style bathrooms can feature metal shelves or brass finishes, which add warmth to the decor. Live edge wood, iron handles, and hooks are rustic touches that maintain the functionality while enhancing the bathroom’s aesthetic.

When designing a tiny house bathroom, sustainability is a paramount concern. Homeowners aim to reduce both their ecological footprint and utility costs through smart design and product choices.

Water-Saving Fixtures

Low-flow toilets and water-saving showerheads are essential in a tiny house bathroom. These fixtures drastically cut down on water usage. For example, dual-flush toilets give the option to use less water for liquid waste. Similarly, modern showerheads can provide an invigorating shower experience while using a fraction of the water traditional models would.

  • Toilets: Consider options like composting toilets which not only save water but also convert waste into usable compost for gardens, an innovative solution seen in many tiny house bathrooms.
  • Showers: Select a two-person shower featuring water-efficient nozzles, which can conserve water while maintaining strong water pressure.

Eco-Friendly Materials

Using sustainable materials can enhance the environmental efficiency of tiny house bathrooms. Recycled glass, bamboo, and locally sourced lumber are just a few options that offer durability and an aesthetically pleasing look without depleting natural resources.

  • Countertops: Recycled glass is not only stylish but also durable and non-porous, making it a prime choice for bathroom surfaces.
  • Cabinetry and Fixtures: Bamboo is a fast-growing material that serves as a strong, mold-resistant alternative to traditional wood, ideal for areas exposed to moisture.

By integrating water-saving fixtures and eco-friendly materials, tiny house owners can create a bathroom that aligns with values of conservation and sustainability.

Accessibility Features

The tiny bathroom includes grab bars, a roll-in shower, and a raised toilet seat for accessibility

Creating an inclusive space in a tiny house is essential, especially for individuals with mobility challenges. This section focuses on integrating accessibility features in tiny house bathrooms, highlighting grab bars and walk-in showers.

Grab Bars

Grab bars provide stability and support for individuals with mobility difficulties. In the design featured by The Spruce, bathrooms can be equipped with robust iron handles to assist in movement. Ideally, grab bars should be installed beside the toilet, along the shower walls, and next to the sink to ensure safety and convenience.

Walk-In Showers

Walk-in showers are a critical component of an accessible bathroom, allowing for easy entrance without the need to step over a threshold. Wheelchair Accessible Tiny House Plans emphasize the use of a roll-in shower, which affords a barrier-free access point and enough space to maneuver comfortably within the enclosure. This can be paired with a handheld showerhead to enhance independence further.
