    About our prices

    Prices are per m² and inclusive of GST. They’re supplied by the manufacturer or distributor and indicative only. Installation costs may be additional.

    POA stands for “price on application”. Some manufacturers don’t supply estimates of price per m² for their products, so you may have to ask in-store. A few of these products can only be installed by specialists, so installation cost is tied up with product cost – these specialists should usually provide free quotes.
