The wallpaper is so dark that I recommend that you make sure the wall art is very light in color. Art.com has a wide selection of art. Get a print, then get it framed in plexiglass where you live. Below is just one example. Another suggestion I'll make is to add a carefully placed wall mirror (make sure there is a good reflection of the window - put it on the right wall that we see in this picture) to get more light in the room. Additionally, please educate yourself about lighting and get good and appropriate lighting. Lighing is often seen as an afterthought. However, in this dark room, it will be crucial to attend to it. https://www.art.com/products/p58484854494-sa-i12655342/paul-cezanne-trees-and-rocks-no-1-c-1895-w-c-graphite-on-off-white-laid-paper.htm?upi=Q1W5EE92H1VXB&PODConfigID=9436046

Bought an imperfect Victorian house in 90's (was turned into 2 family many years prior). Rental unit had dusty rose bathroom fixtures in excellent shape. Replaced floor, walls with beadboard & tub surround all in cream & beige. Replaced toilet and free standing sink (room is VERY small ) with white but kept cast iron pink tub.

Moved into unit myself 8/9 yrs ago; used a white shower curtain that covered the (still in great shape) dusty rose tub. Didn't bother me a bit. Am now about to finally remove tub and replace with a walk in shower for ease & safety.

(Had newer fiberglass tub in FL; no comparison to porcelain). It all comes down to budget and preferences. If this is the last reno you will be doing & can afford it, change all unless you can't rationalize the expense.

PS: I did have the old white porcelain tub in the other unit (I was living in) reglazed due to wear. Toilet & sink replaced. Reglazing tub hideously smelly experience & shine eventually wears off over years despite using Soft Scrub.

Good luck!
