I updated our main floor powder room, which had worn-out white
tile on the floor of the shower, a standard builder vanity,
porcelain sink, and mirror, and a white tile countertop. I saved money
by keeping the existing shower walls and door, and only replaced the
tile on the shower floor. I also kept the same tile on the floor, but I
had to find and match some additional tile to put under the new vanity.

Here's the BEFORE:
