We offer up to three free samples per customer on all bathroom/shower panels and flooring products. If you would like to take advance of this service, please fill out our Request Form.

• Panel colours may vary between batches due to manufacturing and procurement processes.
• Please ensure you purchase enough panels for your project. We cannot guarantee to match batches between different orders. If you require an exact match, please keep a note of the batch numbers that appear on your packaging so we can check availability and try our best to assist you.
• All measurements provided are approximate.
• PVC panels are classified as building materials and by default are not supplied with edge-to-edge printing along the top and bottom of the panel. You will need to cut the panel to size, eliminating the corrugated edges at either end. This is not a manufacturing defect. An allowance of up to 20mm is required to accommodate this process.
• Please read the fitting instructions in their entirety before installing the product.
• Product images are for illustrative purposes only and may differ slightly from the actual product.
• PVC panels must not be exposed to UV light, both direct and indirect sunlight.
• Always store products flat, resting them on a surface that supports the entirety of product to prevent any bowing.
• Profiles and joint trims are sold separately.
• We strongly recommend that you do not book a fitter or tradesperson until you have received your delivery and are happy with your order. We cannot be held responsible for any third-party costs or charges incurred due to non-delivery of an order, or orders that have not been checked following delivery.
• All deliveries require someone present to sign for and take receipt of the goods. We will not leave goods in a ‘safe place’ without express prior consent.
