We had bought quite a bit of one tile pattern (an almond porcelain tile -- porcelain does really well in wet environments like bathrooms). In two of the bathrooms we used this as the base tile, then mixed it up with glass tiles to give it a reflective sheen in spots.
Overall, the best thing about these particular showers are that today's grout protectant allows you to clean with ease, and that was a big draw for us. We all want clean showers. Having interesting patterns in there is a bonus!
