01 Shipping & freight

For most items, shipping is calculated at checkout from your delivery postcode and cart, and the amount shown is the amount you pay.
Large or bulky items (for example baths and vanities), tiles and flooring delivered outside our free-shipping area require a freight quote. For these orders, the $1 shipping shown at checkout is a placeholder only — it is not the final freight cost.
After you place the order, our team will contact you with the actual freight cost for your address. We will not dispatch your order until you approve that cost. If you choose not to proceed, you will receive a full refund — no obligation.
Any free-shipping offer is a limited-time promotion shown on site and at checkout. It cannot be combined with any other offer or discount. MyHomeware reserves the right to make the final decision.

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.

Smart Bidet Seats FAQs

Can you put a bidet toilet seat on any toilet?

Not necessarily. Most bidet seats for toilets are designed to fit standard Australian toilets, whether round or elongated, but may not be universal to every toilet. A modern seat bidet toilet setup can be a convenient upgrade, and a toilet lid with bidet is often designed to retrofit easily. Still, it’s important to check the size, type, and compatibility before purchase. Many options retrofit easily to existing setups, making installation straightforward without replacing the entire toilet. Many modern bidet toilet seats also include adjustable fittings to improve compatibility across different toilet designs.

Do smart bidet seats increase electricity bills?

A toilet bowl seat warmer uses relatively little power. While heating functions may use around 300–600 watts during operation, they only activate when needed. For most Australian households, the overall electricity cost is modest — especially compared to common appliances. Choosing a well-designed toilet seat and bidet combination with eco modes can further minimise standby energy usage.

How much water does a smart bidet seat use?

A electric toilet seat typically uses around 0.5 to 1 litre of water per wash, depending on spray duration and pressure settings. Most toilet seat bidet designs allow users to adjust water flow, helping minimise usage while maintaining effective cleansing. Compared to the water used in toilet paper production, a bidet and toilet seat system is generally considered a more water-efficient option. This efficiency is one of the reasons why bidet toilet seats are increasingly preferred in modern households.

Do smart bidet seats work with low water pressure?

Most bidet wc seats require stable water pressure to function properly. In homes with low pressure, performance may be reduced, so it’s important to check the electric bidet product specifications before buying.

Do bidet wc seats need a plumber to install in Australia?

In most cases, installation is simple and can be DIY if you're connecting to an existing water inlet. A toilet lid with bidet can usually be fitted without major modifications. However, if electrical wiring or new plumbing is required, a licensed Australian plumber or electrician may be needed to meet local regulations.
