The link below has the Hansgrohe Croma series from Home and Stone - hopefully. Did you get prices locally? I'd compare them with online if you have a list of everything you need. I called Hangrohe, got all my part numbers form them and then ordered online. I had started out with the Croma E, but then switched to the Croma C and ended up ordering the "green" showerheads which use air technology like our current Oxygenic showerheads to make it seem like you are using more water than you actually are. Here is a link that might be useful: Home and Stone

Speakman also gets really good reviews! Newport Brass and a few other very high end fixture lines (I think, I can't remember who now) uses these showerheads for their very expensive shower sets, but you can buy just the shower head for much much less. There are different kinds too - shop around for the best price. For example Newport Brass has a stylish one for $98 for the 6 spray version. If you just look up speakman you can get the same one (with the stylish spray adjuster handle) for about half that. I wish I could report back personally on this showerhead but I haven't started my demo yet :(. When I did a search on showerhead recommendations though, it got almost as many good reviews as the waterpik.

yes..you can use a different shower head..a lot of people use the alson hand held shower units with a message heads

I looked through every brushed nickel colored toilet paper holder on Faucet direct and didn't find anything that was an exact match. Danze Opulence was close to the tile bar, but the TP holder proved it was not the same. I would not suggest trying to find a match. You want to go with good quality plumbing parts, then move to accessories. If you want to leave the accessories, try picking up a brushed nickel from a common company (like Kohler, Moen or delta) and seeing if the color matches.
