waterproofing shower tiles (marble

[Diggerless]

Hey All,

DIY noob here so be gentle!

Please bear in mind that these bathrooms are going to be completely refurbished, starting in the next couple of months

I am currently looking after a large property with several bathrooms. I discovered water dripping from light sockets below the shower I normally use, and eventually discovered a few "holes" in the grouting/sealant between the marble slabs and the marble/showertray join. Plumber says I need to remove all the existing grout up to a certain height and regrout/seal. Currently leaving to dry out. Can someone give me a numpties guide/technique as to how to effect a repair that will last several months?

The other shower I was going to start using whilst the original shower cures/drys oit, I noticed has a couple of much smaller holes too. Although this shower has never been used what product shall I use to "seal" those holes as it seems pointless starting again when it will all be ripped out soon?

Thanks for Looking

You have a lot more problems than a few grout leaks to be talking about water dripping from a lower fixture. You need to get a hold of a professional tile installer who routinely knows how to do a custom shower. As a DIY you can save by doing the tear out, but don't even attempt to put it back in unless you opt for a prefab shower unit. These applications need to be done with 2-3 water barriers with weeps in between layers, etc. Temp fix up 100% silicone in holes and wipe relatively smooth to the surface. A quick fix only. A custom shower lining will cost $3500-5000 depending on the tile you choose. Sorry there is no magic answer or easy solution here unless you choose to put in a prefab unit.

Thanks for that. Like I say all the bathrooms are going to be ripped out in the next couple of months or so, so a temp fix with sealant and regular monitoring should hopefully be enough .
