When you start thinking about a bathroom renovation, it all seems relatively simple – choose some new tiles, get rid of the mouldy shower curtain, replace the taps and vanity that were last updated in the 1950s and you’re good to go, right? Well, turns out that although it’s often the smallest room in the house, the bathroom can be the room that requires the most trades. Everyone gets a piece of the bathroom action (especially if you’re moving walls and the location of plumbing), from plumbers to waterproofers, to renderers to tilers, electricians and builders. In fact, up to 10 different trades could be involved in even a mid-range bathroom reno (let alone the spa-style retreat you’ve been dreaming about). A lot of trades mean a lot of coordination, scheduling and waiting and it’s important to work with a builder who has access to professional, licensed tradesmen he uses regularly (if you need more convincing, read this post about my sister’s bathroom. Nightmare!).
