FAO: DIYers - Grout & Silicone Sealant

[SidewinderINC]

Ahoy hoy,


I'm doing a spot of fixing up in my bathroom (because the landlord is too lazy and I can get the money back from the agents) and am fitting a couple of new tiles at the back of the bath where we put our soaps and shampoos etc. as there was just a film of sealant over a piece of wood previously!
I've stuck the tiles in place using tile adhesive and am waiting a while before grouting in between them and then will seal the edges with silicone.

My question is, after the tiles are stuck to the wall/surface is there any reason I couldn't use silicone sealant between them rather than grout?

The grout is chipping off between a few of the wall tiles and touching it up is going to be a pain and I wasn't sure whether it would have been even possible/suitable to do the whole thing from the start with silicone as it's flexible.
