Due to the width of your bath, and your height, I'm going to recommend something personal - if you are going to this expense it ought to serve you. Most roman tub fillers now have handshowers. You can also wall mount a separate fixture above your soaking tub if you tile the wall and floor. You can add a separate floor drain if you think you need one.

You don't have enough space for a tub and shower unless you make most of the room a wetroom, so I've splurged on a big deep long soaking tub for you - it isn't a little japanese circle but it isn't huge either - can be no more than 68" long / 30" wide unless you skimp on storage. Raise your custom counter to 42" high, and put open tiled shelves aimed at the bath / then appliance garage towards sink, then above, tower storage with door in frosted glass in solid wood (best painted). Storage for everyday things below sink and to right.

Get a high end medicine cabinet in the end wall to right of sink, (more mirror, more storage where you can use it), and center in the rest of the space a nice large mirror.

That is how you get a private toilet space - divide the toilet with floor to ceiling glass installed last . . frosted to 50" high so it can borrow natural light from the skylight . .

Given you have a townhouse with high ceilings, I would play with modern shapes in classic materials - carrera marble on the countertop, soft pearl gray cabinets / tower/ medicine lifted off floor 16" with stainless angle iron beneath, white marble penny round on the walls to 6' plus a carrerra trim cornice tile piece topped with shaker style wood trim piece with hooks every so often along the open walls so you can spray the whole room with abandon . . (paint the door and top trim charcoal). Depending on the colors in your bedroom, you might use yellow accents in both spaces in linen, accent pillows . . or peach, or aqua, .. and a soft pastel of this shade might go on the ceiling .. you could paint the upper walls mid-tone gray and hang an art gallery up on this part in your toilet room . . all silver or white frames .. not so formal art that will be damaged by the humidity but something interesting.

If you can afford an operable skylight, get one. The room has a drain after all ..

Not much can be done due to space constraints as mentioned.

You don't say what surrounds the bathroom. Since your budget is large, you might be able to take space from another room or closet to add to your bathroom so that maybe you could put in a larger tub. I would consider an air tub -- you can use bath salts/oils or bubble bath in them. Failing that, I would consider one of the I would make sure that the plumber installs a shower head high up on the wall or in the ceiling in addition to the hand held (split valve). Definitely get the comfort height toilet and raise up the vanity -- use a kitchen cabinet and raise it up.

Like the higher shower head idea and the kitchen cabinet height for a vanity. My partner is 6'5", so that helps. Does anyone put anything but comfort height in a commode anymore? I have one in my powder room and guests will take me aside and ask for the model number they like it so much.

Libradesigneye, thanks so much for the very thoughtful design. I was steering away from a freestanding tub. Because of space constraints, I thought the alcove shower-tub combo was my only choice. Brilliant frosted glass commode idea. Very compelling.

Here is an option that uses a contoured floating vanity unit to permit more function in this limited space. A generous 60x32" bubble tub with a high-set rain head plus rail hand shower have a fixed glass partition rather than a door, for a more open feel. The doorway view is of the vanity, rather than the toilet.

Genius. Thank you. Where can I find this vanity!

I'll have to check on sources for something similar.
The toilet and shower head are Toto; the hand shower is Brizo; the tub is Kohler Underscore bubble massage. regards, S*

ok, this vanity is actually Italian, company is Stocco, model is Vela. It is modular, so you put together pieces to get the configuration you want.
You can get the pdf catalog from this site: http://www.stocco.it/scheda_collezione_eng.php/IdCollezione=3/NomeCollezione=Vela
There are probably other similar options, of course, but I do like this one! S*

Sstar, I don't want to be a wet blanket, but that layout doesn't meet code - you have to have 60" min for a toilet back to the next thing - maybe the codes allow less when there isn't a partition - but let's be realistic. A commode is approx 30" from the wall, and a bath fanity is usually 20 - that leaves 10" to pass between for knees .. even if you use a 12" cabinet depth across from the commode, you are at 18" - not enough space .. .

You could turn the commode 90 degrees, and put it on the end wall, as you only need 30" min for plumbing access and the width available might depend on the door swing on your cabinet but you could go to open shelves there. . . the location of the door gets to be important then, but you could use the back of an open door as a sort of privacy screen if two are in together

My depiction is of a soaking tub - but they don't have to be freestanding, they come in deck mounted too . . .sstar;s idea of a ceiling mount rain shower head over is brilliant.

Libra, please have a look at this curved vanity unit. It is quite narrow at the point in front of the toilet. That is the point of it.

P2705.1 General.

Some codes such as San Diego require 24" in front of the toilet.
"Water closet clearance. Minimum 30-inch-wide by 24-inchdeep clearance required at front of water closets. (CPC 402.5)"

http://www.sdcounty.ca.gov/pds/docs/pds081.pdf

This means that by "code" you need 52"-54" for a toilet space in some jurisdictions and 49"-51" in many others.

One advice is not to have the toilet right in front of the door. This way its not the first thing you see when you enter and its not visible when the door is open

oh woww, new to this site but now I understand why architects are important!!! great contribution you all...
