I'm renovating my ensuite and will be doing the shower in glass tiles. The walls will be done in the Dove grey 4x16 tile below and on the main wall I'm planning to do a 4x6 ft frame using the black tile. The frame will be one tile wide.

My question is about grouting. Is it possible to use angry grout colour for the main wall and a black grout for the frame or should it be one colour (I.e. Grey/charcoal).

Any thoughts/ideas would be appreciated.

Thanks

M
