Grout gone yellow what to do next

**philibobs6** · 28-02-2010

Hi all, I have previously re tiled my bathroom sometime ago but the shower area has turned the White grout yellow. I tiled on top of existing tiles where underneath one wall is brick the other plywood which is where the shower is. I was looking for a quick fix of regrouting but others have said to strip plasterboard tank and start again, but are there any quick fixes as I have regrouted but does not last. What are the best grouting products, I previously did it with b and q own ready mixed stuff, hear from u all soon regards

firstly b&q own brand grout will probably not stay white for long,use only good quality grouts that are mould resistant,but to save you stripping everything back and re-tiling the entire area could you not use a grout colourant and go for a darker colour?

Stay away from cheap grouts, they will stain in a very short time. You could try cutting the old grout out and re grouting with a decent grout (perhaps as Davis said, in a darker colour?) then you could buy a grout guard. I have used the Lithofin one and have been very happy with the results. But bare in mind that if the staining is coming from the tiles underneath, this will not last long.
