having recently gone thru remodeling my master bath prior to my surgery, tiling is not a lot of fun. However, get CERAMIC subwa tiles for your project, not glass. Or at least not see thru glass.
Ceramic will have the color baked and cured onto it. Get a glossy finish as that means it is sealed and water will notpenetrate it.
My next question would be, what type of surface are you going to lay these on? If their ornamental then your drywall will work fine. Just make sure the wall is FLAT. If not use some leveler on it before tiling so everything is flat.
Don't ya hate it when your wife is right ??????? lol!!!!
Been there and done that more than once... lol!!!!!!
Enjoy the trip to the store.. Check out the subway tile in ceramic while you are there.....
