Retailers often lump bed and bath together when categorizing their goods, with some collections encompassing enough items to allow you to have identical patterns or textiles in both your bedroom and bathroom....
We can imagine this being an option to consider if you perhaps have an ensuite master bath but we have to say we really haven't seen it done very often in "real life" - have you?
The photo above (from Meghan & Shawn's Spacious & Vibrant Flat) shows something we HAVE seen more often - a color story that covers both rooms (in this case, blue, green and white), but with very varied patterns and different intensities of color.
Which way do you go at your home? A very coordinated, matched set of bed and bath goods? Similar colors but that's it? Or totally different from top to toe in the two rooms?
