Thank you all for the compliments.  You're all the best!
But let's take a step back for a minute to a request by Claudia to see a "before" photo.
There's no real "before" because this new bathroom was created by
borrowing space from my dining room, two closets (where the cat
just lost a toy down a hole in the floor) and about two feet of my kitchen.
The door to the kitchen (behind the chandelier) was moved
to the left and an area about 5 feet by 8 feet was closed in for the new bath.
This created a sight line from the front of house all the way to the back.
The old bathroom is behind the sliders in the kitchen and that will now
be demolished so the kitchen can be expanded.

This is the floorplan of the new bath. Just big enough to fit everything.

The guest bath door is a salvaged four panel door that I stripped using the
Silent Paint Remover--a much bigger job than I expected--primed and repainted.
It does look great though.  The porcelain knob is from House of Antique Hardware.

The artwork is a contemporary collage by Massachusetts artist 
Bernd Haussmann.  I already had it and it fits the space perfectly.

The floor tile is Sant'Agostino porcelain tile, color is Ferro Black.
This is the 6 x 24 size and I used a 1/3 stagger that, along with the
linear striations in the tile, gives it the feel of wood.  It's a bonus that the
price point is $9 per square foot.  The grout is Permacolor "Raven."

The small halogen light on the ceiling is probably a place holder.
I have a problem with most flush-mount lights and this one
didn't give me any adverse reactions.  I wanted something modern
and inexpensive and this fit the bill.  I threw out the box with
the name but it came from a local lighting chain called Wolfer's.

This shows the junction of all the materials.

The glass towel rod is vintage.  They can be found on etsy and ebay.

The 3x6 subway tile is American Olean in Ice White which is really
inexpensive stuff.  Available at Lowe's or locally at Roma Tile in Watertown.
The grout is Permacolor Bright White.

The small shelf is cararra marble (see sink info for source).

The Greek key mosaic border is Walker Zanger, Tribeca collection
Adelphia border in Flatiron gray, honed marble.

The planks are shiplapped Southern yellow pine painted with
Benjamin Moore "Icicle," #2142-70.

The chair rail was custom made to match the width of
of the marble mosaic.  The paint color is Benjamin Moore
Stonington Gray HC-170.

The tub is the Kohler Bellwether.  I liked this model because of its
straight front edge.  I thought it was a nice match to the modern
lines of the sink and a counterpoint to the more traditional elements
of the room.

All of the shower jewelry is Rohl from the Country Bath collection.

The shower curtain is Restoration Hardware diamond matelassé in white.
Mary suggested I move the shower curtain rod up to the ceiling.
I tried it and I love it.  It adds a little drama.  Restoration Hardware
makes the same shower curtain in extra long and I think it will be the
perfect length.  Thank you for that suggestion, Mary. 

The vanity table is an antique Swedish console table from Darby Road
in Waltham.  It was too long for the space and had to be cut down in
length to fit but I really loved the turned legs so wanted to make it work.

The original wood top on the table was removed and cut down to make a lower shelf
for additional storage.  Because the side of the shelf had to be cut down, Sam used
a similar routed edge and I did a little faux finish using brown stain and gray paint
to simulate the original worn edge seen on the front of the shelf. 

The plumber did a great job of tucking the turnoff valves way up
under the vanity table to keep the look as clean as possible.
I would have like to have used a bottle trap but they're not
approved for use in Massachusetts for some reason.
The turnoff valves are made by Jaclo.

The sink is Porcher (made by American Standard), the
model is Semplice which unfortunately has been discontinued.
The price was really reasonable so it's a line you should check out.

The new marble vanity top is cararra marble that came from a
remnant from International Stone in Woburn, MA. The people at
International Stone were great to work with and I think their prices are
reasonable so if you're local, it's a place I would recommend.
The basket is from Crate & Barrel.

I took this photo to show the corner details.

The clipped corner was originally on the Swedish console top and leg
so when I found a toilet that had the same corners on the tank and base,
I thought it was a perfect match.  I had the same detail cut into the marble top.

The toilet is the Porcher Lutezia.  I splurged for a fancier
seat with nickel hardware which is by Lefroy Brooks.

Because the chair rail ran right in to the faucet, I designed a bump up
with a little integrated shelf.  The lights are the Bryant sconce by
Thomas O'Brien from Visual Comfort in polished nickel.

The antique Brasscrafters mirror has a nickel frame.  It's unfortunately
too small.  I wanted the top to hit above the level of the sconce shades
but the bottom needs to be lower to make it useful for people shorter
than six feet tall. 
The bottles are the handiwork of Artie Vanderpool from Color Outside

The faucet was my biggest splurge.  It's the St. Germain faucet made by Horus
(from France) in polished nickel.  It comes with either lever or cross handles.
All of the fixtures came from Waterspot which has five showrooms in the area
including the Boston Design Center.

To the left of the sink is a little shelving unit that is built between the studs.
The little painting was a lovely gift from a long-time follower Dianne Ballard
who says it's a portrait of me.  See more of her work in Dianne's etsy shop.
There's another bottle of Artie's, a small vintage unmarked vase,
and a few beakers for supplies.

I think that covers it.  The bath is now open for guests so I put this
little arrangement of milk weed pods, hydrangea, caladium, ferns and ivy
together to welcome you.  It's always nice to have flowers in the house.  
Let me know if I missed anything and thanks again for the great feedback!
