Any DIY experts on here?

[midden]

I would cut a tile with a tile cutter or saw , if you don't have those tools available , I would fill the gap with grout  ,once that has hardened up , seal the gap with sealant , fill the bath with water before applying sealant , apply sealant , I finish it with a ice lolly stick which I dip in washing up liquid , leave the bath filled up for at least 24 hrs .

I've cut similar round plug socket before (younger days didnt think to remove sockets) cutting to aprox 1/2cm from tile edge  using one of these.  delicate job
