Well it is not really mood change tile but it is better! It is Temperature-Sensitive glass tile!
The base color of the tile can be almost any colour, and the temperature change point can be fit to the user’s environment!This application is very versatile and easy to work with. You can use it in showers, bathroom and other interior design features. These 4 in x 4 in x 3/8 in thick glass tiles are so beautiful!
A beautiful tile but it is a huge investment. Costing $33.00 a tile not including installation! So when thinking of getting these beautiful tiles remember the cost may be hefty but the illusion these tiles leave are stunning.
