So we're trying to pick tile for the waterline and the perimeter overflow spa (these maybe be the same or different depending on what we decide to do on the spa). Our builder will do glass without question, but is really trying to make sure we understand the potential issues with it versus ceramic. Curious on the group consensus for the following:
#1 - In the Spa, they say that some glass mosaic can be sharp on the edges. So if you are sliding your posterior over a seat or wall corner, it's possible you could pick up a sharp edge more easily than with ceramic.
#2 - Glass tiles are more fragile to breakage from dropping something on them and again, they can create a cutting hazard if that happens.
#3 - Glass tile may be more difficult to maintain than ceramic, specifically in areas that are prone to hard water staining, like an overflow spa if it is not run 7x24. Is ceramic easier to maintain?
#4 - And this is my own question more related to small mosaic pattern rather than just glass specifically. Is 1x1 or even .75x.75 mosaic on the waterline more difficult to maintain from a scrubbing perspective? Is the extra grout an issue when compared to larger traditional waterline tile?
