Bathroom Renovation Ideas for Homes & Businesses with 2025 Cost Guide

Bathroom renovations are trending across Australia in 2025, particularly in Perth, where homeowners and businesses take the opportunity to upgrade for comfort, style and better customer appeal. At home, bathrooms are transitioning from basic service areas to personal sanctuaries. In commercial settings such as cafes, gyms and salons, well-designed washrooms have become part of the overall brand experience.

But the bathroom renovation ideas are different depending on the location. Families want practicality, storage and easy clean-up. Businesses desire long-lasting, well-accessorised and attractive layouts.

In this blog, we are going to discuss bathroom renovation ideas according to size, style and purpose with detailed cost guides.

Bathroom Renovation Ideas by Size

All bathrooms are not created equal, and that’s why design approaches have to adjust according to the floor space. Whether a narrow apartment en-suite or an expansive master bathroom, the perfect layout and choice of features will make all the difference. Here are some small, medium and large bathroom renovation ideas in Australia that’ll blend style and function.

Small Bathroom Renovation Ideas

Small bathrooms of 4m² or less require smart layout solutions to maximise their space. Wall-hung vanities and floating shelves designed by reputable carpentry services save legroom, while frameless walk-in showers get rid of visual barriers. Light colour palettes in whites, greys or earth tone neutrals should be chosen during a small bathroom remodel. These shades can reflect light and make the space feel bigger. Mirrored cabinets provide additional storage as well as a visual expansion effect.

One of the best bathroom designs for small bathrooms is to borrow from Gen Z styling. Many renovators are doing just that to inject some personality without overtaking the room. Picture bold patterned tiles on the floor with neutral walls, LED backlit mirrors and smart storage niches built into the shower. These petite designs suit smaller spaces such as apartments, powder rooms or commercial environments like cafes or boutique stores where aesthetics are almost as important as function.

Medium Bathroom Renovation Ideas

Large bathrooms between 4 sqm and 8 sqm strike a balance between out-of-the-box design and practical functionality. This is the standard size in Australian family bathrooms. A semi-frameless shower opposite a built-in or freestanding tub provides flexibility for both speedy routines and leisurely soaks. Floating vanities with deep drawers provide generous storage while keeping the room visually light. Recessed niches within the shower are a space-saving alternative to bulky shelves.

As there’s more room to play with, finishes are a chance to take things up a notch. Brushed brass, matte black or brushed nickel tapware will immediately up this ante without any significant price leap. Designer tiles are one of the best mid-size bathroom trends because they serve as a focal point without being overwhelming. Medium-sized bathrooms are ideal for all styles to strike the right balance between durability and visual appeal.

Large Bathroom Renovation Ideas

Bathrooms that are larger than 8m² can open the door to a more opulent arrangement, with many imitating relaxing spa facilities. Double vanities are common large bathroom remodel ideas, particularly in shared master en-suites. 

While the popularity of free-standing baths doesn’t look like it will wane any time soon, many homeowners and accommodation providers are opting for separate wet areas with a dedicated shower and bath on either side to achieve that larger hotel-style layout. With more floor space, you can even consider freestanding tubs and walk-in open showers with seating benches.

This size of washroom is ideal for adding a touch of luxury with heated floors, hands-free fixtures and ambient lighting. Under vanities, in niches and around mirrors, mood lighting can turn the room from functional and bright in the morning to warm and cosy at night. They are especially popular in swanky homes and high-end Airbnbs across Australia, where a bathing area that stands out can add serious value to a property.

Bathroom Design Ideas by Style

Bathrooms have evolved into a reflection of personal style and sensibility. Selecting a design style early in the renovation process informs decisions about fixtures, materials and layouts. Below are some popular bathroom design styles and how they can be adapted for different spaces.

Modern Bathroom Designs

The newest bathroom renovation ideas 2025 focus on straight lines, clean designs and simple elegance. Wall-hung toilets and vanities allow for uninterrupted floor space, which can make a small or medium-sized bathroom appear bigger. The integration of technology with smart mirrors, programmable lighting and touchless fixtures contributes to ease of use.

The colour scheme tends to be neutral or monochrome in appearance with matte black or chrome hardware for a minimalist, modern aesthetic. Modern bathroom renovations are common in new Australian construction and urban apartments, where simple, efficient, and stylish are preferred. Soft LED lights set beneath vanities or around mirrors can cast an ambient glow that enhances the minimalist look even more.

Traditional / Classic Bathroom Designs

Traditional/classic bathrooms often use heritage design, including decorative tapware and freestanding bathtubs. Traditional bathroom tiling patterns can also be used to create a timeless luxury look. These designs look fantastic in older-style homes.

Fine finishes, elaborate trim work and high-quality materials are the highlights in most of the bathroom renovation images. They add a sense of luxury while also investing in the long-term value of a home. The traditional/classic bathroom renovation designs often feature one or more generous storage units, gracious-looking vanities and coordinating accessories. These restrooms generally have a warm, approachable feel that blends style with classic appeal.

Industrial-Style Bathroom Designs

Industrial bathrooms are known for joining exposed pipework and raw, concrete-type finishes with black metal fixtures. It works exceptionally well in large spaces like loft apartments or even commercial venues such as bars and restaurants, but can be modified for medium-sized bathrooms with smart zoning.

The industrial style bathroom ideas combine substance and style, frequently incorporating reclaimed wood, metal touches, and polished concrete floors. Dark colour schemes and bold lighting make this look amazing. Industrial bathrooms are perfect for anyone looking to have a slightly edgy and quirky look without giving up function.

Bathroom Ideas by Function / Purpose

Bathrooms are increasingly designed with specific users in mind, from practical family spaces to luxurious spa retreats or eco-friendly setups. In 2025, functionality and style go hand in hand. Below are popular bathroom ideas based on function and purpose.

Family-Friendly Bathrooms

Family-friendly bathrooms are becoming a major part of home renovations. They prioritise safety, durability and convenience. Anti-slip flooring and the soft-close drawer mechanism minimise accidents, while built-in storage ensures toiletries are kept in order. For those with children, a tub and shower combination is necessary for the ability to give little ones a bath.

Materials are selected for their robustness. Quartz benchtops, strong laminates and scratch-proof mosaic tiling mean the bathroom can handle high-impact daily living. Smart layouts mean adults can also move around comfortably while monitoring children.

Luxury Spa Bathroom Designs

If you want to go beyond the cheapest bathroom remodel ideas, you should choose layouts that can help you relax and unwind on an everyday basis. Soaking tubs, rainfall showerheads and ambient lighting set the scene for luxury master suites or high-end boutique lodgings. Smart bathroom upgrades, including Bluetooth sound systems, aromatherapy diffusers and heated floors, add to the experience and provide an added sense of comfort and style.

These areas tend to be bigger and permit the creation of distinct wet and dry zones, double vanities and speciality lighting to emphasise specific design elements. The luxury spa bathroom ideas promote both function and relaxation, which is why they are popular with homeowners wanting a retreat at home as well as businesses offering elite guest experiences.

Accessible / Age-Friendly Bathroom Designs

Given our ageing population, contemporary bathroom design ideas that are accessible and age-friendly are only going to become more relevant. Shower with bench seating, grab bars, and touchless taps offer safety and usability for all users. Features like non-slip tiles, broader entrances, and lever-type handles make sure the bathroom is easily accessible with mobility aids and the risk of falls is reduced.

They are also critical designs for housing supported through the NDIS and for commercial spaces supporting inclusivity. With thoughtful planning, ergonomic features can blend with style, and the bathroom may still look beautiful while having functional needs.

Eco-Friendly Bathroom Renovation Ideas

Green renovations are becoming a major part of modern bathroom design ideas. They minimise water and energy use, and maximise responsibility in materials selection. Water-saving dual-flush toilets and WELS-rated tapware assist with water saving, and recycled tiles, timber, and countertops lower the environmental footprint. Natural light, either through skylights or solar tubes, or solar-powered ventilation systems, also cuts power use.

In addition to sustainable measures, green-friendly bathrooms frequently offer design elements that contribute to better indoor air quality and extended longevity. It is a perfect renovation for the green-minded homeowner and business owner. Not only does it provide practical functionality, but it also adds a modern, responsible style to your establishment.

Gen Z Bathroom Design Trends

Gen Z is changing bathroom renovations by blending style, technology and convenience. Many of them are renters or first-time home buyers. They favour small to medium-sized contemporary homes with efficient space utilisation and a stylish look. Their choices are indicative of an Instagram-friendly aesthetic.

Key trends include:

• Aesthetic + Smart Tech: LED mirrors, sensor lighting, and touchless taps add convenience while enhancing the modern look.
• Colour Pops: Teal, dusty pink, and terracotta accents, along with terrazzo tiles, create visual interest without overwhelming small spaces.
• Social-Media-Friendly Features: Statement pieces such as freestanding vanities, bold Perth wall tilers, or geometric fixtures make the bathroom photogenic and stylish.
