Gap between shower screen and tile



I will be using a piece of glass set into a glazing channel (which is set in the wall). So the glass looks like it comes straight out of the wall.

I will be tiling next to the screen and want to know what i do when i lay the tiles next to the screen.

Do i leave the normal grout gap and just grout in here or do i need to leave it empty.

Ideally i will use clear silicon down this joint.

It has been mentioned i need to leave an expansion gap, but i thought the grout allowed expansion. bit confused here.

You must leave a small gap to allow for differential expansion & movement of the glass screen but don’t use grout it will crack, fall out & let in water; it’s got to be silicone. Slightly different application but I don’t grout on fire surrounds; I leave approx 1mm gap & fill it with clear silicone, however, this is always on uncut tile edges.

I’ve not tried what you propose but if you use clear silicone I think you will have two problems;
• you will almost certainly see the uneven cut tile line (through the silicone) adjacent to & running down the outside of the glass
• you will also see the raw cut tile edge through the other side of the glass - if you get what I mean.

It may be better to use silicone that matches the colour of your grout but you need to force it fully into the gap if it’s to look good.

I trust it's a toughened safetey glass screen!

Why would you ask if it was toughened saftey glass ? Who would use normal glass as a shower screen ?

I am framing my tiles in a two line course of travertine bricks so i wont have any cuts running up this glass so i could well just use my clear silicone.

Will i need to force the silicone into my ungrouted channel or do i just leave the silicone to sit on the tile and the shower screen ?
