I definitely agree that timber/sea grass/ rattan stools would go well & add some warmth! I honestly don't know about the lights though. I think if it was me I'd stick with stainless & minimal modern for the pendant lighting as that would suit the rest of the kitchen. Then just use other accessories like the stools & a wooden fruit bowl or something to add the warmth.

I think you can very well still have plants in a windowless room- as long as you're willing to give them regular little 'windowsill holidays' in another room. I'd go with succulents, there are some great warm colour combos (see Pinterest for ideas) and the geometric shapes mimic your tiles. Of course, there are some incredible fake ones around too, saw one last week I could not pick from the real thing. I'd be tempted to mix in some of both to balance aesthetics with practicality! Separately, I'd be careful of adding any soft furnishings (rugs, spare towels, etc) to a small powder room. We are all aware these days that a flushed loo spreads germs a meter around it- I wouldn't want to be collecting and trapping them! I think (subtle) fragrance and votives would warm this lovely space without impeding hygiene.

They look great in that photo, Northstar! Works beautifully. Will be fine over your bench. Didn't realise how large your p really space will be. Wow! No, if you replace pendants that have staggered drops, the fittings are completely removed and new pendant fittings are installed in their place. The electrician just shortens the drops without cutting them & the extra lenth is hidden away in ceiling.

For those interested - as expected, the pendants were t going to work on the left side of the vanity due to proximity to the shower... our electrician actually suggested three pinhole/mini recessed down lights spaced over the vanity for task lighting. I think they should look nice and minimal and not clash with our larger surface mounted down lights. Anyway, will post an update pic when it’s all done! Thanks again everyone for your comments. :-)
