Our bathroom has lovely porcelain tiles that wont stay firm and grouted. All tiles, adhesive and grout from Porcelainosa or BAL, installed by professionals, but who seem to be reaching the limit of their skills by what shouldn't be that tricky a job. Total bathroom area about 9x6'
The (first floor) base is a wooden ply on original 1930s joists that is far from flat, although extra noggins have been put between the joists since the first go.
The tiles have been laid and grouted three times each time by a different proper tiler, and they have started rocking again, with the grout disappearing. With the amount of water splashing about at kids' bathtimes, I'm worried about water getting through gaps in the grout and not drying.
Taking all the tiles up would be tricky, as they run throughout the bathroom under the bath, that is itself fitted and fixed into a gap by the wall tiles, so I don't see taking the bath out as an option, though the sink and WC, and boiler cupboard could.
If I'd known the hassle I would have had a more forgiving flooring in the first place - probably high quality vinyl - I love the Moduleo stuff we have in the kitchen. However the same porcelain tiles have been fine in a nearby ensuite on the same type of floor.
Options seem to be:
1. lay vinyl product on top of tiles. Would improve waterproofing but movement would still be an issue.
2. have another tiler have a go at re-laying, hope they stay firm this time.
3. take as many out as possible after removing sink and wc, have the accessible subfloor properly sorted out and tiles laid again
4. as 3. but finish in vinyl (my preferred, probably most expensive)
Any expert thoughts most welcome!
