Depending on where you live, adding or expanding your window space is a good feature to consider. If you are extremely private or live near a walkway or neighbors, you can think about installing a skylight. Windows tend to add value to your home and allow for fresh air to flow through, which is important for bathrooms to prevent mildew/mold. Skylights allow the sky above to brighten up your bathing space, adding a sense of openness. Best of all, window elements can reduce the need for electrical lighting, lowering utility costs.
