Well you could choose different door handle color and just deal with the hinges yourself if you really want something other than brass. If you like brass then use it as I see nothing wrong with it. I think brass goes with anything. In my old house my master had brushed brass and brushed nickel faucets/towelbars/towel rings and I used brushed nickle for the knobs and handles for the cabinets there and the mirrors. So even if you wanted to use some with a silver finish you could get something that has a little brass on it and tie it in. The door to the bath had iron handles and black hinges. Here is a pic where you can kind of see it: Towel bar has outer ring in brushed brass and the point that holds the ring and the rest is nickel. Some brass finishes and others that I think would work well too. Bronze Brushed brass vs. shiny (not sure what your hinges will be). antique brass Black also would look good. I'm not a matchy match person though and I don't think I could do all the same color on all my fixtures in the house. In our new house the baths are brushed nickel, door handles are ORB and light fixtures varies from iron look to antique brass, and brushed nickel in the baths. Kitchen faucet is brushed stainless and the pendant above it is antique brass with an amber shade. Bath knobs and pulls will be brushed nickel, not sure about the kitchen, but I'm leaning towards ORB, pewter, or antique brass due to the dark cabinets and wanting it to not stick out too much.

Differences, 123A has that 113A does not: Louvered Coil Guard Powder Painted protects the condensing coil. Low Ambient Capability with Kit Low Pressure Switch High Pressure Switch Compressor Sound Blanket Quieter In my opinion, it's night and day just in the look and feel of the condenser, the sturdiness, It's quieter. In larger units you may squeak out a little bit more efficiency with builder series because of the coil guard difference has less restriction of air flow but I just hate the flimsy wire frame. There is very little price difference not even worth mentioning so I never suggest the RNC level. Also in spring RNC for Bryant and Carrier will go away. These system will move to the base level and everything above will move up. Bryant and Carrier are re organizing their lines based on the electronic packages the different models offer.

In my area, the larger subdivisions by a single builder (or a group together) usually buy containter loads of pre fabbed granite straight from China. They then have the carpenter try to fabricate it to fit. Some of the results are quite painful to view. Most are merely bad. But, they're able to then use the "granite countertops" buzzwords in their adds trying desparately to entice a buyer. The container loads are usually Baltic Brown, Tropic Brown, etc. The commoner and less expensive granites, and certainly not top quality. They then over use them in every kitchen, so that most homeowners are sick of these granites in the same way that homeowners became sick of oak cabinetry because most builders installed poor quality builder's grade oak cabinets.

Not easy to do because you will have to essentially "remodel" the space. Unless I am misunderstanding you would be ripping out the all in one unit which typcaly includes the walls and the tub and replacing it with a tub that has tiled walls. Building a tiled shower correctly is probably the single most expensive part of a bath remodel. You would require new walls - waterproofing in the walls as well as I would think a new tub since wasn't the old tub attached to the enclosure? I had one of those all in one type of tub/shower enclosures and it was essentially a singe unit. Would the fixtures be salvagable? I can't imagine it would be less expensive than whatever the builder charges to upgrade when building.
