Yes , thermostatic valves are for 2 or more outlets. It's not worth the added cost to have one for 2 outlets maybe 3+ but not 2. Thermocartridges run about $150-500 As a plumber myself I would just get two normal shower valves. The total handles are the same lol. Thermostatic valves have hot and cold flowing past the thermovalve with out a shutoff. If the valve isn't working correctly and the internal stops you can have a cross connection hot and cold because again the volume control shut off is after the thermo valve it's live always! If you went to a show room they get commission on fixtures. If someone can't give a equel pros and cons to a suggestion.it's that good or bad. Or, they are pushing it on you. Have a extra $250 cartridge on hand for once the valve is flushed and checks cleaned then replace cartridge. Answer from CapPretend6677 on reddit.com

r/askaplumber on Reddit: Brizo Thermostatic Shower Control
September 30, 2025 -

EDIT: Delta/Brizo is sending a new cartridge, and we will try that. Thanks for all the assistance.

Plumbers, please help! I had my main bathroom redone. I hired a reputable contractor. We bought our fixtures at a plumbing supply store. After talking to them, we liked the idea of the thermostatic shower, as we had some small issues with the temperature changing when flushing, but there's only two of us, so no big deal. Now, however, with this Brizo controller, we can't get a hot shower and a cold shower. We can only get warm and cool. If we have the plumber turn down the cold, the hot gets less hot. If we want it hot, we can only get to warm on the cold side. Is this how it is supposed to work? NO ONE TOLD US THIS. I hate this controller right now, and if I can't get this fixed, I don't know what to do.
