0–3 days to process & dispatch in-stock orders
2–7 days metro delivery after dispatch for in-stock items

01 Free shipping

  • Free shipping to Greater Sydney on online orders, plus selected surrounding NSW regions including Central Coast, Newcastle, Port Stephens, Wollongong, Nowra and Goulburn, as well as Canberra/ACT — large items included.
  • Tiles and large items delivered to all other areas are quoted separately. Start a Live Chat using the chat icon at the bottom right of the screen, and we'll confirm the freight cost for you.
  • Free shipping cannot be combined with any other discount, promotional code or offer.

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
Delivery timeframes are estimates calculated in business days from the date of dispatch, not from the date the order is placed, and apply to in-stock items. For backordered items, please see Section 07. Actual delivery times may vary depending on the courier and destination.

03 Order processing & delays

  • You'll receive an Order Confirmation Email as soon as your order has been successfully placed.
  • Please allow 0–3 business days for order processing. In most cases, in-stock orders are dispatched within the first 24 hours.
  • Once your order has been dispatched, we'll email you the tracking information.

Some delays may occur due to circumstances outside our control:

  • Public holidays, peak trading periods and major sale events may extend processing and delivery times. During Christmas and major sale periods, please allow extra time.
  • Exceptionally high order volumes may occasionally extend processing times.
Remote areas: Courier networks may have delivery limitations for some remote postcodes. Where door-to-door delivery is unavailable, your parcel may be delivered to a local depot or Australia Post outlet, and you'll be notified when it is ready for collection.

04 Additional delivery charges

Additional charges beyond the standard delivery fee may apply where:

  • Stair or lift access is required — for example, where the delivery point is not directly accessible or goods need to be carried up stairs. Additional charges may apply due to the extra labour and time required.
  • The delivery location is difficult to access, or two or more people are required to complete the delivery safely.
Any additional charges are assessed on a case-by-case basis, 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 delivery window, a redelivery fee may apply.
  • Any additional charge will be communicated to you and agreed before a second delivery attempt is arranged.
  • Please ensure that you or an authorised person is available at the delivery address during the agreed delivery window.

06 Pickup

  • We'll prepare your order as soon as possible and email you a notification with your booking number and collection details once it is ready.
  • Please wait until you receive this confirmation email before coming to collect your order.
