It does not chip, peel, or fade like lacquered or plated alternatives. The surface oxidizes naturally with water and air, deepening in tone and character over time. Each fixture develops a patina unique to your water chemistry and usage — a living finish that no factory can replicate.\u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal\"\u003eThermostatic Temperature Control\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe concealed thermostatic mixing valve maintains a precise, user-set water temperature — even when pressure fluctuates elsewhere in the home. No cold shocks. No scalding spikes. Two separate controls on the trim plate allow independent adjustment of temperature and flow, giving you full command of your shower experience. The valve is fully compatible with standard U.S. residential plumbing and operates across a working pressure range of 7.25 PSI to 145 PSI.\u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal\"\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; font-family: Arial, sans-serif; font-size: 14px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #b8860b; color: #ffffff;\"\u003e\n\u003cth style=\"padding: 12px 16px; text-align: left; font-weight: 600;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 12px 16px; text-align: left; font-weight: 600;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #fdf8f0;\"\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; font-weight: 600; color: #5a4a2a;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; color: #333;\"\u003eSolid Unlacquered Brass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; font-weight: 600; color: #5a4a2a;\"\u003eFinish\u003c\/td\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; color: #333;\"\u003eLiving Finish (Natural Patina)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fdf8f0;\"\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; font-weight: 600; color: #5a4a2a;\"\u003eHandle Accents\u003c\/td\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; color: #333;\"\u003eWhite Porcelain Levers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; font-weight: 600; color: #5a4a2a;\"\u003eInstallation Type\u003c\/td\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; color: #333;\"\u003eConcealed \/ Built-In (In-Wall Valve)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fdf8f0;\"\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; font-weight: 600; color: #5a4a2a;\"\u003eWater Connection\u003c\/td\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; color: #333;\"\u003eStandard G½\" Thread (U.S. Compatible)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"padding: 11px 16px; border-bottom: 1px solid #e8d8b0; font-weight: 600; color: #5a4a2a;\"\u003eMin.
