I think your choice to go with hardwood through the whole main floor (because it's a half bath only, I probably would have gone with the hardwood in the powder room too - although a high gloss porcelain could be very luxe too).  

The Quick Recipe We Used in Our Kitchen-Light Quartz Countertops-Porcelain Mosaic Backsplash (in a complementary color)-With Dark Wood Shaker Style Cabinets (for contrast)-A Fabulous Shiny Faucet (for pop)-Color Pendants (for more Pop)-Stainless Steel Appliances-Vinyl Floors (yes, vinyl!)

I use wood looking porcelain tile if it is a house. 

Since we have the stainless appliances, the porcelain wood grain tile floors, the granite, and so on, and brand new privacy fences and newly installed patios with pavers, we think our units are comparable to the high end apartments, but without the community facilities those come with.

I'm a big fan of porcelain tile wood look planks 6"X24".

I put in granite tops, pullout faucets, porcelain backsplashes, and microwave hoods, plus dishwashers in the 2BRs.  

PPS - Based on what I am seeing in the comps photos I received, I am planning to install "B" level granite (probably Santa Cecilia) while reusing the existing drop in sink, porcelain tile or "stone-look" LVT floors, tile backsplash, and (hopefully) relatively inexpensive "semi-custom" cabinets (to make the most of the available space in a small kitchen where there is no possibility to expand the room).If anyone has advice about good value semi-custom cabinets, please share it with me!

@Mike ReynoldsA high-fire ceramics kiln can get to 2350F to fire porcelain and stoneware glazes.

Here's how you find the right person to ask:1 - Go in that room with all the porcelain plumbing fixtures. 2 - Turn on the light3 - Look just over that fixture with the water in it. 

I have recently been suggested to do 6" x 36" porcelain or ceramic plank flooring ("wood look") throughout the entire house, including all the bathrooms and bedrooms.
