For each bathroom choose a neutral color that U see in the tile Here is how to find the perfect wall paint "match" http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/

They are tiles I feel which had been fixed on top...so its difficult ot paint of tiles , just try ot polish them with a polish liquid ...if you need a different looks ,then you need to remove the existing tiles and paint whatever color you want...but for fountains and water surfaces , try ro avoid paint as the paint degrades ...

Karthik, Interesting. Not sure who would have advised you to get these tiles. Usually, these are meant for bathrooms and swimming pools. Let us get back to you on suggestions to work around this one. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.

Either, you can paint all the walls with light grey or white colour. Or, highlight one wall with light grey colour and rest of the walls can be white.
