Open your valves back up after installation one at a time, slowly letting in a little bit of water. This will test your drains and make sure you have no leaks. If you do find a small leak, you can use Teflon tape right on the threads, or tighten up the valves a little more. Make sure you don't tighten them too much. Just get them snug. It's the seal that stops the leak, not the tightness.
1. Remove the doors and drawers from the vanity when installing. This will remove any risk of damaging the doors or drawers when you are installing the unit.
2. The best way to cut off the extra from the shims is to score them with a utility knife. Then, fold it up and back down to break it off. This will provide a clean break so you won't have to worry about damaging the cabinets by using a hammer and chisel.
3. Always measure the area of where you want to install the vanity before purchasing the unit. With the old vanity removed, you can even draw out on the wall with a pencil the dimensions of your desired vanity. This will ensure you have adequate space and the right unit for your bathroom.
4. When removing the old vanity, watch out for clips. If your clips don't come off easily, break them off, but be careful not to break the sink. The sink is much easier to take off in once piece than small, broken pieces on the floor.
