Top 10 Small Bathroom Renovation Ideas to Transform Tight Spaces in 2025

Small bathroom renovations reshape Australian homes, particularly in burgeoning cities such as Perth in 2025. As urban density grows and compact living becomes the norm, many homeowners are revamping their bathrooms to make the most of limited space. Previous layouts, a limited amount of storage, and bad lighting generally cause these cramped spaces to feel more cramped than they are.

But a renovation doesn’t have to entail starting from scratch or blowing the budget. With clever design, modern fittings, and stylish features, small bathrooms are now easy to create and design to look fabulous. 

Whether you are renovating a small ensuite guest bathroom or a city apartment, these small bathroom remodel ideas will help you maximise space without compromising on style or comfort.

Top 10 Small Bathroom Renovation Ideas for 2025

1. Install Floating Vanities for a Spacious Look

Floating vanities are a go-to solution in modern small bathroom remodels. By lifting the unit off the floor, these vanities open up the room visually and allow light to flow beneath, making the space feel larger. They also enhance airflow and reduce the risk of water damage, often caused by tight floor contact.

Ideal materials for Perth homes include moisture-resistant timber, compact laminate, and engineered stone tops that blend durability with contemporary design. Floating vanities offer the added benefit of wall-hung storage – great for keeping toiletries organised without crowding the space. From a small bathroom redesign perspective, these vanities are both aesthetic and practical. 

They are especially useful in space-saving bathroom layouts where every centimetre matters. To enhance functionality, consider vanities with drawers incorporating organisers or sliding trays, adding even more usability to a small space. Floating vanities also make future plumbing access easier, which is a bonus for maintenance down the track. 

2. Frameless Glass Shower Screens to Open Up the Room

Frameless glass shower screens are very popular in 2025 bathroom design trends, and for good reason. Perfect for narrow layouts or corner showers, frameless glass creates a seamless look that instantly makes your bathroom feel more open. They also require less hardware, meaning fewer surfaces to clean and maintain – a bonus in busy households.

Matte black or brushed brass hinges and fittings are trending in Australian homes, adding a sleek, modern edge. Frameless screens are particularly effective when paired with large tiles or neutral palettes for a minimalistic finish.

Frameless glass also offers longevity. Without the seals and frames that tend to trap moisture, there is less chance of mildew buildup over time. These screens eliminate bulky frames, allowing the eye to travel uninterrupted across the room – an essential trick in compact bathroom upgrades.

3. Use Oversized Mirrors to Enhance Depth and Light

Mirrors play a powerful role in any minor bathroom redesign, especially when strategically placed to reflect both natural and artificial light. Oversized mirrors, in particular, can dramatically enhance the perceived size of your space. Pairing mirrors with LED backlighting not only offers a clean ambient glow but also taps into innovative bathroom technology trends that are reshaping homes across Perth.

Choose mirrors that suit your bathroom’s theme – a round backlit design works beautifully in modern layouts, while framed or bevelled mirrors complement classic settings. It is one of the simplest storage solutions for small bathrooms that visually doubles your room.

Mirrors placed opposite windows can maximise light penetration, while mirror arrangements above vanities can anchor the entire look.

4. Vertical Storage Cabinets to Maximise Wall Space

Before diving into specific furniture, it is worth noting that vertical storage is the foundation of smart design in tight spaces. Especially in bathrooms where floor area is scarce, making the most of your wall real estate is key.

If floor space is limited, think vertical. Tall storage cabinets, slimline towers, and even floating shelves provide the perfect storage solutions for small bathrooms. These units make use of otherwise wasted wall space to house towels, toiletries, and cleaning supplies.

This approach ensures your daily essentials are within easy reach but not cluttering the bench or floor. For those considering a small bathroom remodel on a budget, opting for open shelving or DIY wall-mounted racks can be both affordable and stylish.

Gloss finishes in white or soft grey help reflect light, while natural wood tones can warm up the room. Vertical storage also works beautifully in narrow bathrooms and offers flexibility, ideal for families or shared living spaces.

5. Add Skylights or Natural Light Sources

Adding natural light not only enhances comfort but also contributes to eco-friendly bathroom designs. In smaller bathrooms, light can be transformative, offering a sense of freshness and openness that artificial lighting often fails to match. Bathrooms without windows can feel dark and confined, but natural light instantly changes that. 

Natural lighting does not just make the space feel larger – it is also essential for an eco-friendly bathroom design.  For Perth homeowners, skylights are especially practical, given the abundance of sunshine year-round. Pair natural light with pale tiles or mirrors for maximum effect. These upgrades also align with current small bathroom renovation ideas, trends, favouring light and airy spaces.

6. Go Light with Colour Palettes for a Brighter Feel

A light colour palette can transform the feel of a small bathroom more than any other single design choice. The right shades create visual openness and a calming ambience, essential for such intimate spaces.

When dealing with tight bathrooms, lighter shades are your best friend. In 2025, bathroom design trends include cream soft sand, pastel green, and warm whites – all of which help bounce light and visually expand the room.

To add interest without overcrowding, use contrasting tiles on feature walls or the floor. For example, a soft grey tile with a matte finish can ground the room, while light walls keep things open. Incorporating these tones into your small bathroom redesign not only elevates aesthetics but also aligns with broader bathroom design trends seen in new builds and home upgrades throughout Australia.

7. Wall-Hung Toilets to Free Up Floor Space

Creating the illusion of space often comes down to exposing more floor area. Wall-hung fixtures do just that by keeping the ground visually open – an especially effective tactic in narrow or awkwardly shaped bathrooms. A wall-hung toilet is a clever option in any modern small bathroom remodel. By concealing the cistern behind the wall and suspending the bowl, this design gives the illusion of more space and creates a cleaner, sleeker look.

These toilets are not only stylish but functional. They make cleaning easier – no more struggling to mop behind the base. Plus, many newer models come with water-saving flush systems that support eco-friendly bathroom designs.

Installing a wall-hung toilet is an excellent way to improve your space-saving bathroom layout while still delivering premium comfort. It is a feature commonly found in upscale Perth homes, particularly in new townhouses and apartments.

8. Incorporate Smart Bathroom Technology

Smart homes are becoming more common, and the bathroom is part of that shift. Integrating Smart bathroom technology improves both hygiene and comfort, especially in tight spaces where touch-free features matter.

Tech is reshaping home renovation services around Australia, and bathrooms are included. Innovative bathroom technology remains a top trend in 2025 bathroom design trends – expect sensor lights, touchless taps, and programmable heated rails. These features go beyond luxury. They improve hygiene while reducing energy use. Smart exhaust fans control moisture and help prevent mould. Digital showers offer temperature presets for every member of the family.

During small bathroom renovations, adding smart features is a smart move. They upgrade functionality and make daily tasks easier, helpful for time-poor households across Australia. Bluetooth speakers installed inside mirrors or ceiling lights add function and fun. Water meters with smart tracking help lower long-term usage and support efficient homes.

9. Use Multifunctional Furniture for Tight Spaces

Every item in a small bathroom needs to serve a purpose. The more useful a unit is, the better, which is why dual-use furniture supports both practicality and clean design. Items with built-in features are great for small bathroom remodels on a budget. Mirror cupboards that hide storage or vanities with layered drawers increase function without using extra space.

In Perth homes with growing families, these compact bathroom upgrades are sensible and cost-effective. Add pull-out racks, corner shelves, or under-sink laundry combos to maximise efficiency.

Multifunctional designs work well in rentals and apartments where space is limited. You blend design with function and make better use of every square metre. Use open-frame vanities to reduce weight and increase airflow. Modular kits are another smart pick – they arrive ready to use and reduce setup time.

10. Wet Room Layouts for Seamless Flow

Before picking finishes, layout planning is the first significant challenge. Wet rooms simplify that by removing barriers – perfect for people who want clear function and ease. Wet rooms make the entire bathroom into a water-safe space and are growing in popularity across Australia. This setup improves flow in small rooms and suits space-saving bathroom layouts.

Wet rooms also support mobility needs. They are ideal for children, seniors, or anyone who needs step-free zones. Fewer corners also mean easier cleaning. If you are planning small bathroom renovations in Perth that include a shower, this layout delivers both visual clarity and easy maintenance. Just ensure waterproofing and drainage are done correctly.
