Think Long Term
Unlike both paint and wallpaper, relaying tiles is neither a simple or cost-effective process. Hence when choosing your floor tiles do take care and think long term. Do not get caught up in the excitement of the moment!
Only Buy Quality
As pedantic as this sounds, use only quality tiles. As said above, it is not that simple to go and change once you have already had tiles laid. So pick only the best ones you can.
Avoid fragmentation of visual space
Top designers suggest that a floor to ceiling tiles look is far better than having small patches of walls covered with tiles. So, in case you are thinking of tiles for walls as well, it is better to go all the way to avoid fragmentation of visual space.
It is okay to think beyond. There are plenty of tile options that looks like marble, coak, Faux Wood, Pebble, etc.
Hire Professional to Install
If installed in the wrong way or aligned in the improper fashion, even the best tiles look dull and unattractive. It is always best to hire professional help for this.
