The return policy is listed when you scroll down to View Seller and Shipping information on the right hand side of your screen. I've pasted it here for your easy reference:

We take great pride in 100% customer satisfaction. If for any reason, you're not satisfied with your purchase, we've outlined the following guidelines to help make your return a smooth and seamless experience:

• You may return your unused item in its original condition and packaging within 14 days of receipt.
• Please request a return by clicking on the "Return Item" button for your order on https://www.houzz.com/browseOrders.
• Unless your item is received damaged, or there was some error on our part, you will be responsible for all return shipping costs.
• Because refunds will not be issued in full for items damaged in return shipping or returns that are never received, we highly recommend that you insure all return shipments and provide Houzz Support with the shipment tracking number.

Thank you!
