4. Sketch it out.
A rough sketch of the layout of the space will help you narrow down the fixtures, cabinets and storage options you'd like to incorporate.
5. Measure everything more than once.
It may sound persnickety, but taking the time to measure things twice will help you to ensure that you don't need to make costly returns or corrections.
6. Replace the underlayment.
If you're ripping up flooring and fixtures, consider replacing the underlayment. Not only does this allow you to start fresh, it also gets rid of any water damage, which commonly occurs in the humid bathroom environment.
7. Reduce the impact of the renovation.
Move your stuff over to another area of the house that is not being remodeled before the work begins. That way you can find what you need and it won't be in your way.
