Hi Mike sorry for the late reply I havent been on the forum much lately. My other half made our CWD viv out of a wardrobe that was ex catalogue stock. He found the curved glass when he was doing a house clearance, but we think it is from a shower cubicle or something similar. My only advice would be to make sure you waterproof it well as we didnt and some of the wood has blown where the dragons have been splashing about while swimming...lol. Happy Building!!! x
