Small bathroom remodeling can often present quite a challenge due to the small amount of space you have to work in. This useful video I found shows an actual remodeling project actually undertaken rather than one of those glossy home makeover programs where everything can seem a bit unreal and too easy. I have actually found this as a useful way to look at the different stages of a renovation plan.
A lot of the initial work is involved in positioning the the various items such as sinks, toilet bath and shower in the room. Planning this way will prevent a lot of expensive mistakes and corrections later on in the project. One useful way I have approached this stage is to actually cut out rough shapes of the various items from newspaper and place these on the floor to see if they fit and which arrangement makes the best use of space.
As you can see, any bathroom remodeling project can often be quite messy, especially if you are undertaking a complete replacement of all the bathroom utilities. Therefore, protecting other parts of the house, with things such as carpet covers is vital.
