Shipping

Delivery timeframes, order processing, pickup and delivery charges — everything about getting your order to you.

Last updated 15 July 2026

Free shipping to Greater Sydney, online orders
0–3 days to process and dispatch your order
2–7 days metro delivery after dispatch

01 Free shipping

  • Free shipping to Greater Sydney on online orders only.
  • Large or bulky items to other regions require a freight quote. Start a Live Chat (chat icon, bottom right) and we'll quote it for you.

02 Standard delivery timeframes

Destination Delivery time after dispatch
Metro areas (all states) 2–7 business days
Regional areas (all states) 7–15 business days
Timeframes are estimates counted in business days from the date of dispatch, not from the date of order. The actual delivery time depends on the courier carrying your parcel.

03 Order processing & delays

  • You'll receive an Order Confirmation Email as soon as your order goes through.
  • Please allow 0–3 business days for processing — in most cases we dispatch within the first 24 hours.
  • Once your order ships, we'll email you the tracking information.

Some delays sit outside our control:

  • Public holidays, peak periods and sale periods add time. During Christmas and major sales, please allow extra.
  • High order volumes may occasionally extend the timeframe slightly.
Remote areas: all courier networks have limits. For some remote postcodes couriers will not deliver to the door — your parcel goes to a local depot or Australia Post outlet, and you'll be notified to collect it.

04 Additional delivery charges

Charges beyond the base delivery fee may apply where:

  • Stair or lift access is needed — if the delivery point isn't directly accessible, or goods must be carried up stairs, this adds labour and time.
  • The location is difficult to reach, or two or more people are needed to deliver safely.
These are assessed case by case, quoted and agreed with you before we proceed, and billed on a separate invoice. No surprises.

05 Missed deliveries

  • If nobody is available at the delivery address during the agreed window, a re-delivery fee may apply.
  • Any extra charge will be communicated and agreed with you before a second attempt.
  • Please make sure you or an authorised person is present at the agreed time.

06 Pick up

  • We'll get your order ready as soon as possible and email you a notification with your booking number and collection details.
  • Please wait for that email before coming in.

In-Wall Cistern Buttons FAQs

How to open a wall mounted toilet flush button?

To open a wall-mounted flush button, gently press and slide or lift the button plate, depending on the model. Most designs are clip-on and can be removed tool-free. Always check the manufacturer’s instructions to avoid damaging the flush plate or access panel.

Why is the flush button not working on my wall mounted toilet?

If the flush button isn’t working, the issue may be a disconnected or damaged actuator, a faulty flush valve, or a problem with the in-wall cistern mechanism. Check if the button feels loose or stuck. Removing the flush plate allows access to inspect internal components.

Can I replace the flush button on a flush myself?

Yes, in most cases, you can replace a flush button yourself. Wall-mounted buttons are typically clip-on and easy to remove. Ensure you choose a compatible replacement that matches your in wall cistern model. Turn off the water supply before installation and follow the manufacturer's guidelines.

Do toilet flush buttons fit all cistern brands?

No, toilet flush buttons are not always universally compatible. They are often designed to work with specific in-wall cistern systems like Geberit, R&T, or Fienza. Always check compatibility before purchasing a replacement to ensure proper fit and function with your cistern model.
