Mongo my house would give you a headache :oP I have the yellows and the silvers in the same room. I don't have any families of anything that are all the same family :) I do have similar finishes for similar items, and I did keep style flowing, (ie no victorian with modern etc) but I do have some mixed finishes as well as similars. For instance, in my kitchen, I have stainless and chrome for the faucets. The knobs are antique pewter and the stove knobs are chrome with a brass accent (Lacanche). Because I have the brass accent on the stove, I also carried it to the lighting which is aluminum and brass in color (yup yellow and silver). It's antique and the color mix flows well in the room. My powder room sink is not the same brand as the toilet, and the faucets are brass. I did go with brass in the lighting as well since there's not a silver accent to pull in like in the kitchen. My master is Oil Rubbed Bronze, but the knobs are antique gold (with a black antiquing rubbed over them) so I guess i have bronze and gold in there :) The shower is a different brand than the waterfall faucet for the tub and the faucets on the sinks are also a different brand. The toilet is toto and the tub amarich...the sinks...mexican copper. In the family bath the faucet/shower is chrome as well as the sink faucet (though I'm thinking of changing that to a fabulous turtle faucet I just saw in a design magazine). The knobs are antique pewter and the towel bars, etc are all brushed silver. So like items are like finishes if that makes sense? The systems are not necessarily the same (most from Pottery Barn, but some from other places). I see it as having like with like. Don't have a brown toilet with a white tub, etc. And honestly...any contractor who can't handle that isn't worth employing! I fired any plumber who whined about the unusual faucets, vessel sinks, etc. I don't want a putz trying to install a vessel sink of mine if such simple plumbing confuses them.

Sorry I can't help with the manufacture but based on the temperature settings on the larger valve I'd say it's a thermostatic shower system. By the way, I like the tile.

WTH! Omg! OK I get it about the dangers of lead. Just a question. If it is illegal to sell faucets that are not safety approved in US then why are they getting away with selling them? Why haven't they been tested or shut down? This is a company that is being allowed to sell spigots that could poison people!!! If it is illegal then why are they getting away with it? Ive never had to consider that a spigot I bought and installed in my home would poison my family. I live i an area that has little options to purchase off the shelf. I'm left to shop online now for any home improvements. Its a scary thought not knowing where it came from, or what it could be made out of. Most everything we buy today at big box stores is made in China.

I have a grohe shower system. I have great water pressure but I think that has to do with my city water psi setting and I also have a 3/4 valve with 3/4 pipes rather than standard 1/2 valve and pipes. I have lots of heads in my shower that can be used all together or alone and the temp is reached within seconds of turning on the water even though it is two floors above the water heater. Not sure, but I think this has to due with the thermostatic valve aswell because my other showers with pressure balance valves take much longer to hit set temps even though they are much closer to the water heater. These showers do still have great water pressure though. I love my grohe shower fixtures and have had no issues in the four years I have had them. my only complaint is I can not ever have a cold shower the water temp can not go below 70degrees. I also like that the temp settings are numeric.
