Installation of a new sink or toilet may seem like a simple project, but you should be aware of the issues that may arise during the process. If any part of the system attached to your toilet or sink is broken or if there is invisible rot in the inside area, or even worse if the tiles break during the installation process, it won't be an easy DIY project anymore.
Really, when it comes to installing something in your bathroom, you truly want a professional for the job. After having installed hundreds of thousands of sinks, fixtures, bathtubs, showers etc. for over two decades we have certainly learned a thing or two about how to get such projects done the right way!!
