Walk-in and accessible showers

A walk-in shower removes the hob, step or bath edge so you can walk straight in, and an accessible shower adds grab rail support, a seat and a floor that suits a walker or shower chair. The work is close to a tiled shower rebuild, which a 2026 Australian guide prices at $4,000 to $9,500 before any wider renovation.

Who asks for a walk-in shower?

Most requests fall into a few groups:

• older owners who want to stay in their home and stop climbing into a bath to shower
• families with a member who uses a wheelchair, walker or shower chair
• people recovering from surgery or managing a long-term condition
• owners who simply want a larger, open shower without a door to clean
• landlords and property managers updating a unit before re-letting

If someone in the house has a disability or is an older person receiving support, talk to their occupational therapist before choosing fittings. A provider can build what an assessment specifies, but should not be the one deciding what a person needs.

Which conversion suits your bathroom?

Starting point	Typical conversion	Main extra work
Shower over bath	Bath removed, tiled walk-in shower in the same space	Floor screed to fall, new waste, wall tiling where the bath sat
Hobbed shower with screen	Hob removed, floor regraded so the shower is level with the room	Waterstop and membrane extended, sometimes the whole floor redone
Moulded tray	Tray removed, tiled level-entry floor	Waste moved or a linear drain fitted, framing repaired
Whole bathroom	Full redesign around a level-entry shower	Same steps as a renovation; see the cost bands below

For context, the Melbourne renovation guide puts a basic full renovation at $10,500 to $21,000 and a mid-range one at $21,000 to $36,750. Membrane replacement and retiling of a shower area is listed in a Melbourne tiling guide at $2,000 to $4,000.

How is a level-entry shower kept watertight?

Without a hob, the floor and the waterstop do the job a hob used to do. The Building and Plumbing Commission’s wet area guidance explains that for an unenclosed shower, the shower area extends 1500mm horizontally from the shower rose connection. The floor inside that area must be waterproofed and fall to a waste at between 1:80 and 1:50, with a waterstop at the edge that finishes flush with the floor. In a small bathroom that radius can take in most of the floor, and the same guidance covers the case where the whole wet area floor is waterproofed, with a waterstop at the doorway.

That is why a level-entry conversion on a concrete slab can need the slab set down or the bathroom floor built up, and on a timber floor the joists may need packing down. Both are decisions for the provider and, where structure changes, a building surveyor.

What should a provider allow for in an accessible shower?

• Grab rail support. Rails need solid backing in the wall framing. If the walls are opened, ask for timber noggings or sheet backing at the heights your therapist specifies, even for rails added later.
• Floor tiles. Ask for tiles classified for slip resistance in wet areas under AS 4586, and check the classification on the supplier’s data sheet.
• Tapware. Lever mixers and a hand shower on a rail suit more people than fixed roses and twist taps.
• Space. A shower chair or a carer needs room; a fixed screen panel instead of a door keeps the opening clear.
• Circulation. Doorways, the toilet position and the vanity height matter as much as the shower.

AS 1428.1 sets minimum design requirements for access by people with disabilities in new building work. Some designers use its dimensions as a reference, but a home bathroom should be planned around the person who will use it and their therapist’s report.

Can NDIS funding help?

The NDIS describes home modifications as minor or complex. Minor changes do not affect the structure; complex ones do, or need custom or technical work. A home modification assessor recommends the changes. The NDIS says it only pays for work done by tradespeople qualified for that type of work, and it does not fund cosmetic finishes such as tiles or tapware that are not needed as part of the modification. Funding only applies to a home the participant owns or one whose owner agrees to the change.

If funding is involved, confirm the approval and the assessor’s report before a provider orders materials.

Which rules apply?

The usual bathroom rules: a registered builder for combined-trade work worth more than ten thousand dollars, a major domestic building contract above the same figure, and cover under the BPC Home Warranty scheme for eligible contracts above twenty thousand dollars signed from 1 July 2026. A building permit is needed if the conversion alters a load-bearing part of the house. Plumbing and electrical certificates are issued at the end. You can check a builder or plumber on the BPC practitioner search.

What a careful provider will not do

They will not take the hob out without setting the floor fall and waterstop correctly. They will not fit grab rails to plasterboard alone. They will not choose fittings for a person with a disability against the advice of that person’s therapist.

What to do next

Note what you are converting from, who will use the shower, and whether an assessment or funding is involved. If the bath or shower base is also leaking, mention it, since the shower base replacement page and the leaking shower guide cover the repair side. Independent renovators receive these requests and quote on their own account; this site is the go-between. Start a walk-in shower enquiry and give your suburb, such as Mill Park or South Morang.
