Bathroom Renovation Costs in South Australia

​​

If you are planning a bathroom renovation, the first question is usually: how much will it cost?

In South Australia, a realistic 2026 bathroom renovation generally costs between $16,000 and $40,000+, with many homeowners in Adelaide, Southern Adelaide, Northern Adelaide and regional South Australia spending approximately $22,000–$32,000.

​

The final price depends on the bathroom’s size, existing condition, selected fixtures and finishes, access, and whether the current plumbing layout remains unchanged.

​

These estimates are suitable for common bathroom renovation projects, including master bathrooms, shared bathrooms and family bathrooms. Larger bathrooms, bathrooms with separate toilets, and projects involving structural or layout changes may cost more.

​

​

Typical Bathroom Renovation Price Ranges

​

Essentials Bathroom: $16,000–$22,000

​

A complete renovation using practical, good-quality products may include:

• Full strip-out and waste removal

• Wall and floor preparation

• Waterproofing

• Plumbing and electrical work where required

• Standard fixtures and tapware

• Single or compact double vanity

• Toilet suite

• Framed or semi-frameless shower screen

• Standard tiles and laying patterns

• Shower niche or practical storage

• Required compliance and certification

​

This package may suit investment properties, pre-sale renovations and homeowners wanting a clean, modern bathroom without premium finishes.

​

For a compact shared bathroom or smaller master bathroom, retaining the existing layout can help keep the project towards the lower end of this range.

​

​

Plus Bathroom: $22,000–$32,000

​

This is a popular choice for South Australian owner-occupiers and may include:

• Higher-quality tapware and fixtures

• Improved vanity storage

• Larger or double vanity

• Semi-frameless or frameless shower glazing

• Feature tiles

• Larger-format tiles

• More generous wall tiling

• Improved lighting and ventilation

• Customised storage niches

• Higher-quality accessories

• Upgraded toilet and shower fittings

​

This level offers a strong balance between appearance, durability and budget, making it suitable for many master bathrooms and shared family bathrooms.

​

​

Premier Bathroom: $32,000–$40,000+

​

This level focuses on custom design, premium finishes and a more personalised result. It may include:

• Full-height tiling

• Feature walls

• Designer tapware

• Custom cabinetry

• Stone benchtops

• Frameless shower screens

• In-wall toilet cisterns

• Premium mirrors and lighting

• Double vanities

• Freestanding bath

• Custom storage

• Heated towel rails or underfloor heating

• Accessibility modifications

​

Larger master bathrooms, luxury homes, bathrooms with separate toilets and projects involving structural changes may exceed this range.

​

​

What Affects the Cost?

​

1. Changing the Layout

​

Retaining the existing toilet, shower, bath and vanity positions is one of the best ways to control costs.

Moving plumbing can involve cutting into concrete slabs, rerouting waste pipes, altering water lines and rebuilding walls or floors. A layout change may add approximately $2,400–$6,400, depending on the complexity of the work.

Moving or adding a bathtub, relocating a toilet or changing the position of the shower may increase the cost further.

​

2. Bathroom Size and Number of Fixtures

​

A larger master bathroom generally requires more waterproofing, tiling, flooring, cabinetry and labour than a compact bathroom.

The number of fixtures also affects the price. A bathroom with a shower, bath, double vanity and toilet will usually cost more than a smaller shared bathroom with a single vanity and shower.

​

3. Tiles and Coverage

​

Standard tiles may cost from approximately $32 per square metre, while larger-format, natural-stone and premium designer tiles can cost approximately $64–$120+ per square metre.

Full-height wall tiling costs more than partial-height finishes. Straight-lay patterns are generally more economical, while herringbone, hexagonal and brickbond patterns require additional labour and may produce more wastage.

Tile selection also affects preparation time, cutting, waterproofing details and installation complexity.

​

4. Fixtures and Tapware

​

A standard mixer and shower set may cost approximately $400–$640, while premium designer products can exceed $2,000.

​

The same price differences apply to:

• Vanity mixers

• Shower systems

• Bathtubs

• Toilets

• Towel rails

• Robe hooks

• Toilet-roll holders

• Other bathroom accessories

A double vanity, freestanding bath or ceiling-mounted shower may also increase both supply and installation costs.

​

5. Vanity and Storage

​

Off-the-shelf vanities may start at approximately $640–$1,200. Custom cabinetry with stone benchtops, soft-close drawers and integrated basins can cost approximately $2,800–$5,600+.

Allow separately for:

• Mirrored cabinets

• LED mirrors

• Recessed wall niches

• Custom shelving

• Linen storage

• Additional cabinetry around toilets or baths

Shared bathrooms may benefit from extra storage, while master bathrooms often include larger vanities or double basins.

​

6. Baths and Separate Toilets

​

Adding or replacing a bathtub can affect the cost depending on the type selected and whether plumbing needs to be moved.

Freestanding baths may require additional floor preparation, exposed tapware and more detailed finishing. A bathroom with a separate toilet will also involve additional fixtures, tiling, ventilation and potentially more extensive plumbing work.

​

7. Hidden Problems

​

Older South Australian homes may contain:

• Outdated plumbing

• Previous non-compliant work

• Inadequate waterproofing

• Water damage or timber rot

• Damaged flooring

• Asbestos-containing materials

• Uneven or deteriorated walls

• Structural movement

• Poorly installed drainage

​

For a bathroom more than 20 years old, allowing a 5–10% contingency is sensible, particularly where there are signs of leaks, movement or deterioration.

​

8. Access and Location

​

Upper-floor bathrooms, apartments, narrow-access homes and regional properties may cost more due to additional labour, protection and project-management requirements.

Apartment renovations may also require strata or community-title approval, waterproofing documentation and protection of shared areas.

These projects may cost approximately $1,200–$2,400 more than comparable work in an accessible freestanding home.

Frequently Asked Questions

​

What is the average bathroom renovation cost in South Australia?

​

A full bathroom renovation generally costs approximately $18,000–$32,000. Compact, standard renovations may cost less, while premium, larger or structurally complex projects can exceed $40,000.

​

Is a master bathroom more expensive than a shared bathroom?

​

Not always. The cost depends on the room’s size, number of fixtures, layout and selected finishes.

A shared bathroom with a bath, shower, toilet and double vanity may cost more than a compact master bathroom. However, master bathrooms often cost more when they include larger layouts, premium fittings, double vanities, freestanding baths or custom cabinetry.

​

How long does a bathroom renovation take?

​

Allow approximately three to six weeks on site, plus four to eight weeks for planning, product ordering, approvals and material lead times.

​

Is approval required?

​

A straightforward bathroom renovation may not require the same approvals as creating a new bathroom. However, all plumbing, electrical and waterproofing work must comply with applicable requirements.

Structural changes, new windows, significant layout alterations, apartments and new bathrooms may require additional approvals. Your licensed builder should confirm this before work starts.

​

How can I reduce the cost?

​

To help control the budget:

• Keep the existing plumbing layout

• Choose standard tile sizes

• Use mid-range tapware

• Select an off-the-shelf vanity

• Choose locally available products

• Use simple tile-laying patterns

• Limit custom cabinetry

• Avoid unnecessary structural changes

​

Can the work be completed in stages?

​

The core wet-area work is generally best completed as one coordinated project. Waterproofing, tiling and fixture installation must follow the correct sequence for compliance and warranty purposes.

Decorative items, mirrors and some accessories may be added later, but staging the main renovation can increase labour, project-management and material costs.

Whether you are renovating in Adelaide, the Adelaide Hills, the Barossa, the Fleurieu Peninsula or elsewhere in South Australia, an on-site consultation is the best way to confirm your project cost.
