2026 bands for Hills District homes

These ranges are a guide for planning in 2026. Each home is priced after a measure, and the written quote is what counts.

Wet area Typical 2026 range Usually includes
Powder room or guest toilet $9,000 – $16,000 Toilet, basin and vanity, floor and part-wall tiling, lighting
Small or second bathroom $17,000 – $26,000 Shower, toilet, vanity, full membrane, floor-to-ceiling shower tiling
Master ensuite $19,000 – $31,000 Walk-in shower, vanity with drawers, mirror cabinet, exhaust ducted outside
Upstairs main bathroom $25,000 – $39,000 Bath and shower or larger shower, full strip-out, membrane, tiling and fit-off
Large or premium main bathroom $39,000 – $58,000 Freestanding bath, double vanity, premium tile and tapware, heating
Laundry $10,000 – $22,000 Cabinetry, benchtop, inset tub, tiling and plumbing

Accessible bathrooms follow the same bands, plus the cost of level-entry showers, reinforcement, rails and wider doorways.

What is inside a Hills bathroom quote

  • Site protection through the house and up the stairs.
  • Demolition, skip and waste removal.
  • Framing and floor sheeting repairs where needed.
  • Plumbing and electrical rough-in and fit-off.
  • Wet-area sheeting, membrane and certificate.
  • Screed, floor tiling and wall tiling.
  • Vanity, basin, toilet, tapware, shower glass, mirror and accessories.
  • Exhaust fan and lighting.
  • Final clean and handover.

What pushes the price up

Moving fixtures. Relocating a toilet or shower means new drainage. Upstairs on a timber floor this can be manageable; downstairs on a slab it often means cutting concrete.

Asbestos. Testing is inexpensive. Removal by a licensed removalist, with clearance, is a separate cost.

Water damage. Replacing swollen particleboard flooring or rotten framing under an old shower.

Tile choices. Large-format tiles, mosaics, patterns and feature walls take more labour and more preparation.

Heating and extras. Underfloor heating, heated towel rails, recessed cabinets and skylights.

Access and distance. Steep driveways, apartments with lifts and restricted hours, or acreage properties further out.

Where you can save

  • Keep the layout. Leaving the toilet, shower and vanity waste positions where they are.
  • Mix tile prices. A premium feature tile in the niche, and a good-quality standard porcelain elsewhere.
  • Choose fixed glass panels rather than hinged doors where the layout allows.
  • Renovate rooms together to share trade visits.
  • Lock in selections early so there are no delays or rushed substitutions.

Payments in NSW

The maximum deposit for residential building work in NSW is 10 per cent. For work over $20,000, home building compensation cover must be in place before a deposit is requested. Progress payments should match completed stages of work, and you should receive a written contract before work begins.

Turning a band into a price

A measure confirms the room size, the floor structure, where the waste lines run and what you want from the room. From there you receive a written, itemised price. See how we renovate.

FAQs

Questions people ask before they commit

How much should we budget for a main bathroom in Castle Hill?

As a 2026 guide, most upstairs main bathrooms in two-storey Hills homes are between $25,000 and $39,000. Larger rooms, premium tiles and tapware, or a layout change can take that to $39,000 to $58,000.

Why do quotes for the same bathroom vary so much?

Usually because they include different things. One may allow a low tile budget, patch the membrane or leave out the asbestos test, while another prices full-height tiling and a certified membrane. An itemised quote shows the difference.

How much deposit can a builder ask for in NSW?

The maximum deposit for residential building work in NSW is 10 per cent of the contract price. For work over $20,000, home building compensation cover must be in place before the builder asks for a deposit.

Does renovating two bathrooms together save money?

Per room, generally yes. The skip, site protection, trade call-outs and waterproofing visits are shared. The household must still have a working shower somewhere while both rooms are out.

Is asbestos removal included?

It is priced separately once a sample confirms whether asbestos is present. Homes built or renovated before about 1990 are tested before demolition.
