Help! Tiled whole bathroom with Tubbed adhesive only to find out it’s not showerproof

[Bbbecca7]

In a bit of a nightmare here

We recently spent a lot of money having our bathroom re-plastered (plaster board and skimmed) to make the walls smooth and square ready for tiling

My dad and husband have been tiling it and have done a lovely job! (My dad has done it a few times but it’s my husbands first time)

HOWEVER.. popped to b&q with my husband today to buy more adhesive and when I read the tub it said only suitable for areas of intermittent wetness.. not suitable for showers! (The b&q shelf label refers to it as waterproof and so dies the description on their website but the tub says otherwise)

We have rang the helpline and the guy said it is waterproof but not shower proof (eh!?) but that it should be fine if it is sealed and grouted properly. And that he has told others this and known it used.

The shower in question is an over bath shower so it won’t get as much water contact as a proper shower but I’m still concerned

Is there some kind of sealent/waterproofing membrane type thing I could apply between tiles before grouting?

What would you guys do in my position? It’s our first house and don’t want any disasters .. but also don’t want to make them pull the tiles off and have to potentially buy new ones at £200!

The tiles are very well stuck on and not able to be pulled off

Any help would be massively appreciated.. I’m trying not to act too annoyed at their mistake as they’ve done a brill job and worked very hard and I don’t want to be ungrateful but the mood isn’t great between us right now!

Not sure if it makes much difference but my shower (in question) is over a bath not a wet room or a shower tray

It doesn’t make a huge amount of difference. Out of the two I’d suggest that a shower above a bath is the less likely to require tanking.

As already mentioned, it will probably be fine. A point to consider though is making sure your Bath to tile joint is sealed before you install your shower screen, your shower valve shroud(s) is sealed to the tiles, especially important if a shroud sits on top of a grout joint. Shower tidy holes are sealed alongside any slider bar you might have. Also period checking/maintenance of the Silicon seals and grout is also worthwhile.

I think I’m the only female on this thread and the only one not arguing!

ACTUAL ON TOPIC QUESTION:

Bal or Webber grout???

Out of the two I’d go with Bal. something like Microflex or Micromax 2.

Thanks for that. Will make sure to do all of the above. We have our tanking kit (Ardex)
For the bath and a grout sealing spray which we will use often

No problem, we have given our views on how it should be done so hopefully you can make an educated decision with future projects and I apologise for my part in any petty squabbling that I might’ve been involved in on your thread.

I'm confused now, is the tanking kit for another room or have you stripped back what had been done?

So we haven’t yet tiled down completely to the bath .. there’s still a row of tiles to go ( the one on the top edge of the bath) so I thought I may as well tank that part! And the walls under/around the bath

Ahh, OK.
