With most old houses walls and floors are not straight and perfect, however wall tiles can go some way concealing this. I don't know if a reputable tradesperson will fix glass panels to old tiles and be happy to guarantee the job. Seems like an ideal opportunity for mould growth between the old tiles and the new glass if any shower water gets an opportunity to seep around the edges or joints of the glass. I think you may be surprised just how much this type of glass costs to install, and you would probably be better off doing the job properly with new tiles and a proper waterproof membrane as required by the building regulations (which your old shower recess doesn't have). In the future your potential new buyers will probably appreciate a freshly renovated bathroom that conforms with the current building regulations (with standard tiling) rather than a glass panel over mould in a bathromm that doesn't comply with the regulations.

I have a new glass pool fence and glass shower screen. I am contemplating having a nanotechnology based product sprayed on (by a professional) that supposedly makes the water bead off, dirt does not stick to it as much, it requires less cleaning and the product doesn't affect the clarity of the glass. Quote is for about $2600 for the pool glass fence and 2 bathroom shower screens. It's alot of money so I want to see if it is worth it. Has anyone had experience with this outdoors or indoors? Does it really work? Does the glass look better for longer between cleans? Any company or product recommendations?

Maybe not enough silicon between channel and glass BUT you need to call the installer and have them take a look at it. Silicon takes at least 24hrs to cure so it may not have been dry enough to use - did you give it a test poke? Also if you use the shower and bump the glass before it totally dries you’ll cause a gap through which water will leak.

I use Spray N Wipe and one of those green scrubber pads -- the harsh ones and the ones with a sponge on one side don't seem as good as the $1.99 for 5 cheapies at New World . People reckon they scratch the glass , but I've got showers that have had this treatment for 20 years , and still seem fine . I used CLR ( Calcium Lime Rust ) years ago -- no better than Spray N Wipe IMO but $30 for half a litre or something like that . Shower Witch is a bit better , but something like $150 for 2 litres and not as good as promoted IMO .
