Bathroom design trend #4: Shampoo niches built for beauty and function. Many times these niches can bring some style, color, and texture to a surround of plain surfaces. Make these larger than necessary so they can become a focal point in your shower.
If you have one of those gigantic builder mirrors over your bathroom vanity, don't rip it out! Simply trim it out with inexpensive wood painted to match your decor. I have seen this done "framing" the mirror, but never down the center.
