Fastest and easiest? Hire a great pro. If not that, I'm not sure there's a fast and easy option unless you're super disciplined about decision making. Here's what I did, roughly, and my tile guy and salesperson said I was faster than most, and the bathrooms look good. Not perfect. But we're happy with them. Since you've selected fixtures and vanities you like, prioritize your considerations. What matters most to you? Aesthetics? Function? Maintenance? Budget? Make a list. Ruthlessly eliminate products that don't fit your criteria. Narrow color and material choices to three for tile, three for counters. Go look. Limit time in stores/showrooms to no more than half an hour (okay, maybe an hour if you've got multiple rooms) at a time. Set a timer. Bring home samples. They probably won't be the ones you thought you'd like. Repeat this process up to three times until you get something that looks good. If you can't find anything you like, hire the pro. Remember: There is no One True Choice. Suspecting there is leads to trials and tribulation. Do not take this path. We're doing four new bathrooms in a massive remodel. The way this process worked in the master bath my husband will use went like this. For the countertops, maintenance and function are most important to us. He's a bad splasher and a bad cleaner. Never sees water spots or that blob of shaving cream he spilled. So counters can't etch or stain. Quartz fits the bill and our budget. He wants white. Not my first color choice, but easy enough. Same will work in guest bathroom and laundry room, thus making efficient use of slabs. Pick the most reasonably priced quality product in the store giving me the nice discount. Be thorough with research, but don't over analyze. Set a deadline for your decision. Stick to it. We chose tile at the same time. Budget was important here, as well as maintenance. DH said he wanted something that looked like a "Roman" bathroom. I interpreted this as marble. No. Not going there with his spilling habit, aversion to wiping things down and cleaning in general. So porcelain or ceramic tile. Fewer grout lines=fewer cleaning woes. I told all this to my salesperson and she immediately directed me to an inexpensive fake carrarra-looking ceramic 18"x18" tile. Works for shower walls. We were going to use it for the floor, too, but a last minute substitution floor tile in another bathroom allowed us to use a grey stone-looking porcelain 12"x24" instead. The contrast looks nice. And we sold the extra 18"x18" to a friend. I started out loving Ann Sacks tiles and New Ravenna mosaics the most, but really, I love tile. The colors, the textures, the possibilities! I could look for hours and imagine all sorts of looks. Then, like everyone else, I had to make real life choices I could live with and afford in the midst of selection fatigue. My salesperson at the tile store was a huge help in narrowing contenders. I found her by looking at Yelp reviews, then went to meet her. She listened well and she knew her products. Great combination, and so helpful. Sorry for the dissertation, when you asked for a nugget. Good luck on your selections. Are you going to post them for us to look at?

Hi Saher Ali- The color marble and the tile go beautifully together! Here is a question though- Marble does stain and etch. Will this bathroom be used to put on beauty/toiletry products on a regular basis? Things do spill. You can use something else that will give you the marble look but that won't have the problems marble does, such as Corian. Here is another thought- I think a slab front cabinet will give you the clean modern look you want much better than the shaker front. Have a look around the internet and you will see. Will you be using the tile shown in the photo of the North Perth bathroom on your floor? If so, that is great. The other floor tile you showed looks more in the tan family and doesn't go as well with the grey/black tones of your marble.

Quality Calacatta is harder to obtain. You need to work with good suppliers for this. You can expect variation, as with any natural stone, but we are seeing, and perhaps due to the mining and availability right now, that there are strong variations. As for pits and chips, well that would not be acceptable. We are wrapping up a very long project and one of the baths is all Calacatta. The countertop will also be Calacatta (carefully selected from our trusted supplier and matched to the tile) but it isn't installed yet so no pictures. Here's some in progress photos. Note the third pic where we stacked the trims pieces in front of the field tile. The trims on the right were a good blend but the left was void of veining and not a good match. As a contractor with relationships and "buying power", we were able to shade all our tile in a dry lay out and return the unacceptable for replacements. You will always have SOME variance so you need to tolerate and expect this. But based on our experience we are able to discriminate between "expected" and unacceptable. It's a beautiful stone and dramatic statement if you can get it right. Good luck with your project.

If it helps I had an ugly Baltic brown granite counter with dated fixtures and dated 4” backsplash/sidesplash, but was not up for a demolition project in this bathroom so left it. . We plopped a new white rectangular semi-recessed Toto sink on top of the old oval hole (the belly of the new sink sits down into the old oval cutout, no cutting & patching). The new sink & faucet stand higher and brighter against the hated brown granite. Relatively low cost low mess. ETA: better pic from realtor’s website, this was a last-minute change before listing
