The owners are very knowledgeable of the health benefits their water offers. The service is superb, so be ready for a quick conversation whilst you fill your jugs! They also sell jugs that vary in size and they offer an outdoor dispenser when the store is closed. Ambience is great and you're sure to tap your feet to the groovy tunes that are always coming out the speakers. They have a lot of regulars because it's just that good! I give this place 4 yumms up and I'll be back for another refill soon!

Coming to Waterhouse is 10x faster and easier than going to a water machine outside a grocery store. The water tastes crisp and you don't have to worry about the last time the machine was serviced. A simple yet amazing addition to Castro valley!

So, its late November 2025. I see on the Castro Valley Vibe IG page about a promotion being…read moreoffered at the Castro Valley Water House for gallons of water. I'm thinking.. " I like water. I like to support my community." So I go in the beginning of December 2025, and talk to Eric I believe. I inquire about a membership and he's all jolly about it and said sure, let's do it. My gut told me, something was off by his reaction. Folks. Listen to your gut. I go a few weeks later in December during the hours of operation. Door is locked, but someone is in there. After a few minutes. They begrudgingly, let me in. I get my water and go. The next time I go to the Waterhouse, its about two days after New Years. There's a sign on the door saying. "Water House is no longer available at this address. If you have any questions or need water service. Please contact Water House directly. Thank you for your cooperation. " Mind you, there is zero contact information on the sign. Luckily, I grabbed a business card the first time I went to this business. So I email them. No response. Then I text the number with my concerns. The response is that they will Zelle or Venmo the money that is owed to me. I probably got about 10 to 12 gallons in total out of my membership. They tell me that they are waiting for the Attorney records and to get back their binder with the memberships and that if I know of any locations they can relocate, to let them know. I don't know any locations. They then tell me I should get a refund within a month. I wait a month and a half and text for updates. No response the first text. 2nd Text, they tell me that they are meeting with lawyer the next day and that soon after they would send me my refund via Zelle. Since that day in February, I've reached out every month since, and NO RESPONSE. Am I salty about it. Without a doubt. I'm sure I'm not the only one that is dealing with this. It's one thing to close down a business. But to then lead me on and say I will be getting a refund soon and then just stop responding. Not cool at all.

I am a women over 60 years old and they don't even offer to help you in handling the full bottles. Even the 3 gallon size. I find them to be absolutely RUDE.
