bathroom modifications with accessible toilet, grab rails and roll-in shower for safe and independent use — *A well-designed NDIS bathroom modification can turn a risky space into a safe and welcoming one.*

The bathroom is one of the most important spaces in any home, but for people living with disability it can also be one of the most dangerous.

Slippery tiles, cramped layouts and hard-to-reach fittings can turn simple daily routines, such as showering or using the toilet, into stressful or even unsafe experiences.

This is where NDIS bathroom modifications make such a difference.

In fact, studies show bathroom renovations are among the most common home changes funded through the NDIS, and for good reason.

With the right modifications in place, participants not only gain independence and safety, but they also reduce the need for daily carer support and improve their overall quality of life.

In this guide, we’ll take you through the full process step by step. You’ll learn about the types of modifications available, how eligibility works, and the outcomes you can realistically expect.

What are NDIS Bathroom Modifications?

In simple terms, NDIS bathroom modifications are adjustments made to your bathroom so you can move around more safely, use the space independently, and reduce the risk of falls or injuries.

Some of the most common modifications include:

Grab rails near toilets and showers to make transfers safer
Roll-in or walk-in showers with built-in seating
Non-slip flooring to lower the risk of slipping
Wider doorways and the removal of raised thresholds for easier access
Lever taps and handheld showers that are simpler to operate
Thermostatic mixing valves that keep water at a safe, consistent temperature

Every bathroom is different, and so is every person’s situation.

That’s why an occupational therapist will always assess your needs before recommending any changes.

Their role is to ensure that the design of your bathroom matches your individual requirements and supports your independence both now and into the future.

What the NDIS Typically Covers in Your Bathroom

The NDIS may approve bathroom modifications if they are considered reasonable and necessary.

In practice, this means the changes must directly relate to your disability, represent good value for money, and genuinely improve your ability to carry out everyday tasks.

Examples of modifications that are often covered include:

Stepless showers that allow access for wheelchairs or walkers
Accessible toilets and vanities with the right clearances for safe use
Fold-down shower seats and support bars
Non-slip flooring and compliant waterproofing for added safety

Adjustable fixtures such as lever handles and handheld showers
Safety features like thermostatic mixing valves to prevent scalding
Improved lighting and contrasting colours for people with low vision
Ventilation systems that manage moisture and help prevent mould

On the other hand, the NDIS generally will not cover purely cosmetic or luxury upgrades.

Designer tiles, high-end fittings, or features chosen for appearance alone usually fall outside of what is considered reasonable and necessary.

Who is Eligible and What Evidence is Needed?

Bathroom modifications are usually covered under the Capital Supports budget of a NDIS plan.

To have them approved, the NDIS requires clear professional evidence that shows why the changes are both reasonable and necessary for your circumstances.

This evidence normally includes:

A detailed occupational therapy report that explains your current challenges, risks and personal goals
Supporting material such as drawings, photos and floor plans that illustrate the need for modifications
Itemised quotes from registered builders, showing costs and confirming that all works will meet compliance standards

The NDIS uses this evidence to decide whether the modifications are both reasonable and necessary for your situation.

The Step-by-Step Process of NDIS Bathroom Modifications

Bathroom renovations carried out under the NDIS follow a structured process.

Knowing what to expect at each stage can make the experience much less stressful and help everything move along more smoothly.

Assessment and Goal Setting

An occupational therapist will visit your home, talk through your needs, and identify any risks or priorities. This first step is about understanding your daily challenges and setting clear goals for the modifications.

Scope and Design

Based on the first step findings from OT, a plan is created. This usually includes layouts, recommended fixtures and finishes, and any special design considerations tailored to your situation.

Quotes and Documentation

Registered builders prepare detailed quotes, which are then added to the OT’s report. Together, this forms the evidence package that will be submitted to the NDIS.

NDIS approval

The full package is sent to the NDIA for review. This step confirms whether the modifications meet the criteria of being reasonable and necessary.

Construction

Once approved, Licensed builders carry out the work. Every stage is carefully managed to make sure all standards are met and that the bathroom will be both safe and durable.

Handover and Training

When the renovation is complete, the space is inspected, warranties are provided, and you’ll be shown how to use any new features safely and confidently.

Many participants who go through this process report noticeable improvements in their independence.

We also found that these modifications can significantly reduce the number of hours of daily care required, giving both participants and carers more freedom in everyday life.

The Costs, Quotes and Timelines

The cost of modifications varies depending on how extensive the work is:

Minor modifications like grab rails or taps may cost only a few hundred dollars.
Moderate changes such as removing a hob, widening a doorway, or replacing flooring may cost several thousand dollars.
Complex renovations that involve reconfiguring the layout, moving plumbing, and full waterproofing often cost tens of thousands

Timelines will also differ from project to project. A small modification might be completed within a day or two, while a full bathroom renovation could take several weeks once the approval has been granted.

The overall timeframe depends on factors such as the complexity of the works, how quickly the NDIA reviews your application, and the availability of builders and materials.

One of the best ways to avoid unnecessary delays is to make sure your occupational therapist’s report is detailed and that your builder’s quotes are clear and itemised.

This ensures the NDIA has all the information it needs to make a timely decision, and it also helps you feel confident about what will be delivered.

Common Pitfalls and How to Avoid Them

Unfortunately, not every modification is carried out correctly.

Some of the most common issues include grab rails being fixed into weak walls, poor drainage that leaves water pooling on the floor, or showers left with raised hobs that make transfers difficult and unsafe.

Inadequate ventilation is another issue that can lead to mold and shorten the lifespan of the bathroom.

The best way to avoid these problems is to choose experienced NDIS-registered builders who work closely with occupational therapists throughout the project.

A thorough pre-build checklist and a final compliance inspection also go a long way in ensuring that everything has been completed to the right standard
