I love your wallpaper. Since it is a powder room, and small (I assume), I would play up the wallpaper. Im not sure if the marble would look too good, it is very classic, but the wallpaper is really cheery and playful. I know it sounds crazy, but one says you can take risks in such a small room.I would go as far as suggesting a colourful vanity top, but not necessarily a stone for budget reasons. Try some red or lighter blue craft paper and lay it on the vanity and see how it feels. Otherwise bring out the colours with hand towels, the mirror or shades for lighting. Happy Decorating!

Paint the walls (lighter version of the soft jade vase color is a great contrast to the vibrant persimmon countertop ...... ), re-paint the cabinets and update hardware, perhaps bin pulls for drawers and vertical handles on doors all in a soft brushed nickel ? Updated new faucets on the sinks can be had for under a hundred each at either typ. DIY store. A shallow upper cabinet in the center of the vanity (against the mirror) would divide the length and add handy storage space for smalls. If you're not crazy about the tile, bring the curtain rod out to the wall above and update with a graphic print fabric using valance and side panels. Be sure your fabric includes the persimmon, jade (or other wall color), the 'peachy' tile color and white cabinet and porcelain colors A solid jade rug and persimmon towels would be great with the patterned fabric. Budget step 2 might include moving the location of the heat vent,a different vanity type and separate mirrors to break down the long space. It looks like all the basics are in good shape so have fun with the great persimmon color !

Kohler's Ceramic Impressions counter and sink is actually much nicer and more suitable for a vanity. It comes in 25" and several colors including a dark gray.

avalon rose, since everything is being redone, it would be silly to leave those low, builder grade vanities. do you have the 90's oak vanity that comes to your thigh and topped w/cultured marble? spend the extra money to update it completely. you'll be so glad you did a year from now. Does insurance give you no credit for materials like tile? here's a longer vanity. no way would I spend 1500 for a countertop and put it on your 25 year old, thigh high oak vanity! lol. Wouldn't this look so much better in your space? beg, borrow or steal if you have to, but do everything at once. You're already getting a break from the insurance company, so look at it like, "redoing the bathroom for half-price". that being said, look on craigslist. You can find some great deals on vanities, and granite or remnant stone pieces. what state are you in? ever hear of pre-fab countertops? you can find a 6' x 22" finished countertop for about $250. get two of them and have a seam. My fabricator would do something like yours for about 800 or so. (install, cut sink holes, seam, edging, etc). go to a stone yard and see what they have But, for your space, I'd prob do a 72" vanity (you can find one just like this on craigslist for : $700 this entire piece, new, 700 or two of these 48" vanities, comes w/marble top and sink, $900. these is all solid wood, no particle board. (resembles RH) you could put a little make-up area in the middle of these two. you could also stick a tower or linen closet type of storage unit at one end to eat up some of that space if you do a 72" vanity or, a make up area in the middle standard height now for vanities is about 36". doing something like this looks so much better than your current one, and you have plenty of counter space. 94", 2800 https://www.bathvanityexperts.com/james-martin-de-soto-825-v94-sl-94-inch-silver-gray-transitional-double-bathroom-vanity.html it would be helpful if you posted a picture of the space. you may get some better ideas.
