Keller supply was great when I was picking out everything I needed for a bathroom remodel but when we had two problems with items we ordered they were less than helpful. We spent a lot of money at Keller and had terrible service. They did not return calls, I got excuses like "the computer was down". I basically had to contact Kohler and Robern myself to resolve the two issue. both of these companies told me that the store where I purchased the product should be helping me with the problem.
I ended up ordering the kit for hanging two medicine cabinets from Build.com which is Fergusons. When we remodel the guest bathroom I am going to use Ferguson's. I just believe that Keller does not want to help anyone who is doing their own contracting. They actually have a large sign "we take care of the industry first". this business is a joke. To this day I have not heard a work about the kit to hang the medicine chest i purchased from Keller. Buyer beware!

The company itself has most of materials that plumbers need but the customer service is horrible. Prices are not cheap but plumbing is not cheap anyways so I can understand. Whenever I go there I get the feeling like the employees at the counter don't care about their job. With online sales on the rise, companies should put more effort on customer service in physical stores.

Keller Supply is the kind of supplyhouse that does not want to sell to DIYers. I needed a couple specialized parts for an HVAC install; I came in (with part numbers!) for a brand their website claims they carry and the counter guy on the phone flat-out told me he'd never heard of that brand. Clearly they don't want the business.

Kellers location might be hard to find but they deliver the best brands and personalized service! I was looking for a higher quality bathroom fixtures than I could find at Home Depot and Lowe's. I looked high and low and eventually found Keller! Stephanie was so helpful by showing me through the extensive high-end Kohler and Grohe fixtures. Assembling my dream bathroom was easy with her help. I totally recommended Keller for quality products and personal service! Ask for Stephanie!

My husband said he found this great place for our bathroom remodel to get fixtures and supplies. After going to other places already I was tired and cranky but I am so glad we went. It's tucked away in the magnolia area but we walked in and I could immediately tell these fixtures were higher end - and the prices weren't that much more than the Home Depot and way better quality. So thankful that Stephanie was there to help us out and included me in all the conversations - rather than ignore me like can usually happen at other stores where they only talk to the man.

I did a bunch of research when it came time to replace our sink and toilet and settled on Kohler. We have an unusual rough in size and it was difficult to find a toilet that would work. I followed Kohler's website to Keller and worked with Lindsey W. I was concerned, since I wasn't ordering from the same line, that they'd be different colors. I was also worried about using Kohler's adapter on the rough in. Lindsey was very helpful, and called Kohler directly to make sure that all the pieces we were discussing would work for our situation.
Though we ended up having a plumber install everything for us, she also made sure to include all the various parts we'd need to do it ourselves (our original plan), including a quality wax ring (per the plumber - who knew?!) that I knew nothing about. When it turned out we were missing some small bolt covers, I contacted her and she immediately placed a replacement order with Kohler. Throughout she's been super responsive, nice, and helpful. Our plumber asked where we got our supplies and when we said Keller, he said they were great, which I think is also worth something.

Very helpful staff who knew what they were talking about! I came in for a master bath remodel, and had absolutely no idea what I was doing. The staff was so kind and took me step by step to ensure I got fixtures that matched and that I genuinely enjoyed. I admit, it was quite overwhelming (who knew there was so much that went into a bathroom!) It looks a little run-down from the outside, but the fixtures displayed inside are vast. 5 stars
