If your tiles are in good condition but you just want to give your bathroom a quick shot of botox then I would suggest looking at coloured Grout Pens. Now your local hardware store ( ie Bunnings ) seem to only carry Grout Paint ( walk away from this product…hideous) or white grout pens …( so boring) ….but I was determined to find coloured grout pens which seemed to not exist.
After many days and nights on the “google” I finally found a little company in Brisbane called http://www.liquidchalk.com.au that saw them overseas in a trade show and started importing them…. And although you may go through a few pens to do a bathroom and there is nothing like practicing to get it right but the results are pretty impressive….and not to mention will save you a bucket of money.
All hail the coloured grout pen.
