As long as the fixture is available to the plumber from a pumping supply house and meets the standards of your state, you can choose fixtures from as many manufacturers as you like. But be careful if you want the finishes to match. The one thing I would not recommend buying used or from an overstock outlet is a toilet. The major issues with toilets from any manufacturer is the quality of the casting and where the bad ones go. Can you guess? I suggest putting the toilet base on a flat concrete floor and seeing if it rocks before leaving the store. Also the size and finish of the trapway and the quality of the seal of the flapper in the tank and the reliability of the float/valve are of major importance. Kohler has been the worst for flushing mechanisms for 30 years but I hear they have gotten better but I will still not specify one. Toto toilets are so wonderful it doesn't matter what they look like.

I look for the ability to repair the equipment easily. I bought all Moen faucets because I can go to any parts store on any day of any week and get replacement cartridges for $10. Moen has used the same cartridge for 30 years or so. I bought an American Standard Cadet "3" toilet after using a Toto for six months and pricing the Toto. The performance of the two toilets is as identical as I can see and hear, but the AS is only about $150. Terry Love is a shill for Toto, so you won't find much about anything else on his site. For shower heads I like to feel the force of the water washing the soap off. I also try to stick with water conserving heads. Rain type heads are neither of those. The one I like is called a Europa. It's under $15 hanging on the rack at Lowe's and/or Home Depot. It is not in with the official shower heads but in with replacement heads. It is easy to disassemble if it gets clogged. For a tub we got a Jacuzzi brand. They claim their internal plumbing all points down so any water in the piping will drain out when the water drains out of the tub.

Here's what I bought for my bathroom renovations: TOTO Drake Elongated Bowl and Tank, Cotton White + seat Hansgrohe KS27185-16181BN Croma 220 Showerpipe with Thermostatic Basic Set Hansgrohe Talis Select S faucet Grohe Essentials accessories If you have a large shower: Hansgrohe Showerpipe 360 Rain Shower System + Basic Set If you have a tub and shower: Hansgrohe 27143001 Croma Showerpipe Hansgrohe Talis S all for bathroom sink Hansrohe Talis S all for kitchen sink I also considered these but opted for the Talis instead: Grohe Concetto all for bathroom sink Grohe Concetto all for kitchen sink

I'm sure I posted this on here before, but the last place, the very last place, I'd get advice on decisions like this are salespeople at appliance retailers. One exception for Yale and Perch in the US. Why? Based on postings on here and my own experience, design, usage, reliability and functionality are not appliance sales people area of expertise. What is their expertise? Whatever gets them the highest commission in the shortest amount of time and with least effort, i.e., in stock products that don't require ordering from the distributors, high margin models and brands, items that don't require complicated installations, anything that is less fuss and effort on their part. When they say something like you posted "the plumbed models have more issues" ask them if they own one themselves, for how long have they used it, are their installers qualifies to install, etc., etc.? Go to the design showrooms and experience centers of the brands you are looking at and ask them, their people are highly experienced and trained.
