How to grout uneven glass tile? Answered

Picture of

I have installed glass "wavy" tiles around the walls of a bathtub/shower.  Each wavy tile is about 2.5" long with a square piece of marble between each glass wave piece.  They are arranged on a 12" square sheet of mesh in a basket weave pattern and each of the pieces are butted up next to each other (leaving no room for grout).  The person at the tile store told me that I didn't need to grout it.  However, given that it is in a bathtub that also used as a shower, I'm thinking it will need to be grouted so water doesn't get up under the tiles and loosen the tiles over time.  Three questions: 1) Do you agree that I need to grout?; 2) How do I go about grouting this wavy tile (it is very uneven... the lowest part of the wave of each tile is 1/8" lower than the top of the wave); 3) As an alternate to grout, is there a clear product I can put on it that will seal up the spaces between the tiles without ruining the shiny finish of the glass?

I've been researching similar tile and it says it's for tile areas. I'm wondering if we can get more input on this from folks who have used similar tile in showers. Here's the one I'm looking at...

This style tile looks great, but isn't designed to be grouted. They should be installed in a dry area. Since you've already installed them in your bath you can enjoy them for a few years, then if you have problems you can treat yourself to a new tile and bathroom remodel (with a bit of work).

If you want to grout your glass tile you need to wait a few days after installation to allow moisture to leave. One advantage of glass tiles is that they are much easier to clean than ceramic tile. You do have some painstaking work ahead of you if you decide to grout your glass tile. Use non sanded grout and maybe use a caulk gun to apply the grout between the oddly shaped glass tiles. If this information helps make an Instructable. You have my best wishes!

Thanks for the response and the tip to wait a few days until the glass tile mortar has cured. A caulk gun to apply grout is an interesting idea that I will play with... regardless and as you mention, there is significant painstaking work ahead.

Don't listen to salespersons; past the point of sake they don't care.

Tiles need grout like bricks need mortar; it's keeping them apart rather than holding them together, and being water-resistant.

Thanks for the response. I was afraid you would say that. Bring on the grout!

Actually, the salesperson is correct. This is a groutless product and is not meant to be used in wet areas. These mosaics are supposed to have tight joints which would allow grouting to be very difficult. Also, trying to clean the grout out of all the crevices will be a nightmare!

Thanks for response. I am [now] convinced that you are correct that this product was not meant for wet surfaces... problem is that the sales person knew where I was putting it and suggested it anyway... and now it is already on the wall - so I'm going to have to make a "go" of the grout thing (bring on the nightmare). I may be scrubbing grout off of glass tile for the next three months, but my choices are now limited. Fortunately, this is a rarely used bathroom.
