Couple of ideas ... 1) cover with stainless steel splashback which is stick on so it can sit over your current one. Should be thinner styles that clad existing ones (or get someone to make you one) 2) attach a vinyl fablon over the glass which is wipeable/washable - the edge finish will depend on if you have anything adjacent to it ie wrap around or cut flush. You can get so many colours and patterns these days and it won’t be expensive to change if you don’t like it. A roll will probably cover it a few times if it gets too dirty but I used a white marble fablon as a worktop cover in my last house. Cost £10! 3) as mentioned- you can get a tile paint or even a glass paint. Try the fablon first though - I would ;0)

its a shame that you didn't go for upstands at the time - but its not the end of the World -its personal - but I do not like quartz going up the wall - glass would look much lighter and give a warmer feel to the room Compac is a lovely product So - either do a glass splashback and an upstand in glass - or just put a piece of glass behind the hob and then pain the walls

Presume you mean covering the whole of the shower wall area? Have you looked at Nuance by Bushboard. Three different price groups depending on which finish you prefer. If you use BB Complete to adhere it to the wall and use as grout in joints it is guaranteed for 3 years. Have just done mine. Son is doing his. Can't fault the stuff. So easy to apply and wipe down.

It's really hard to have an opinion on a screen............uinfortunately, colours just look different to people as the colours on their screens differ from one another.......does that make sense. I can tell you however, having used Dusted Moss 2 & 3 on many occasions, that it is a lot more green than it looks on your chart above, which looks grey. It has grey tones, but as the name suggests it is a green. Dulux is for sure, lovely paint,. The colour charts however, aren't so accurate and the paint mixing compared to the colour cards is also not that accurate. I always suggest to people to go get colour cards and testers and paint at least an A4 piece of paper with 2 or 3 coats. Move the paper around as the paint changes with the light in differing positions. Probably not what you want to hear, but you can't choose paint from a computer screen and hope for any accuracy at all. I now prefer Valspar ( B&Q ), used to be Crown. The colour matching is phenomenal. The accuracy to the cards is spot on, and the paint is good. I used to be a Dulux everything fan................but since discovering Valspar I have been converted.
