I remember years ago being in a similar predicament and someone gave me some mirror tiles - I glued them on the the wall and thought I was very clever. They actually did look much better in my eyes. Try not to spend too much - I think everyone's idea of a shower curtain will all the bathroom colours in it would probably be the best option. You'll laugh about it in years to come and you will love the improvements you make over time. Enjoy the moment, unless you're selling soon your ideas will change after living there, so change when you can afford it - who cares it's YOURS. Good luck, it's so rewarding and so much fun. P.S. now we have a small bathroom, wall to wall tiles, dark grey on the floor and white on all the walls with a large grey tile up each opposing wall, tall mirror over the handbasin which reflects the opposite wall then a full length bath with shower over it. It works perfectly and looks great.

practicallity wise with young kids shaggy is going to be a nightmare ..wool is good as warm in Winter..and hypoallergenic.. Harvey Norman have great rug sales sometimes 40% off just keep an eye out for them.. I don't buy wool I just buy what looks nice and is practical.. 2 of my kids have eczema and they find wool rugs rough and itchy..we used to have a wool rug at our old place..so I only buy synthetic now..

It was one of the colours the Dulux rep recommended. If you can, get sample pots and try them out. Best way to check your colours as photos don't always give a true reflection of the colour. Then you can have a look against your tiles and in different light.

I think that ceaserstone or marble would compete too much with your tiles and could look odd because of that. In the examples you provide, the one lot of marble stairs are with a very plain tile and the other looks like it matches the floor exactly. Your tiles have a bit of a swirly pattern so unless you chose a very plain stone/marble it would clash IMO. Also, ceasarstone can chip and I don't think it would be a very practical option for stairs. Timber would add a bit of warmth to your whole sleek look while still looking modern, and be something to tie your front door in with so it isn't the only warm looking thing in your whole light coloured area.
