How to Install a Bathroom Window

Replacing a bathroom window not only provides energy-efficient savings, it also changes the visual element of your home. Yet if a new window is not properly installed, it can cause damage if it lets in water and makes the window difficult to use. A watertight window is key to a successful installation. Many styles, shapes and colors are available, and windows come in wood, aluminum and vinyl.
