Definitely YAY! We have a couple of small tabletop ones scattered inside our house as well as a waterwall used to separate our foyer and sitting room. We ordered all of them from a website we saw on TV called https://www.soothingwalls.com/ I read somewhere that they also filter the air inside the room but I can't be too sure, honestly! They're super gorg though. Makes any space look mega luxe!

You will probably have 50/50 responses going for and against a waterfall indoor.

Depending on the space I guess they could add a really relaxing feel almost spa-like. Could be nice the right spot, if I could have one in my bathroom I think that would be pretty cool!

I say yes. Go for it. It's going to look amazing.

Make sure you fill it with distilled water to avoid any build up and gunk..

Just as with a swimming pool or pond there is maintenance of pump and cleaning and algae control with any water feature. However if you are willing to take that on then go for it. Water is considered a design element often manifested in glass objects and tables(feng shui) and in the case of the real stuff, adds not only beauty but beautiful meditative sound to an environment.

Installing a recessed fountain into one of your walls can instantly change the look and feel of your home. It provides a luxury and regal sense. Stainless steel and copper are the two most common types. You can find them here:

Here's another that I'm considering from http://www.luxewaterwalls.com/fountains/boss-fountain-16.html it's smaller and would be amazing in a smaller bathroom. I'm thinking this one would be perfect for like, a small powder room?

We say YAY! They're perfect and make a rather dull space stunning! We have a ton of great selection on http://www.SoothingWalls.com

My sister has one and it drives me crazy. It sounds like the toilet is broken and is running nonstop.

They're also supposed to be good for allergies.

My husband always has to pee when he hears running water, so absolutely not! :)

bluenan I think that would make for some awfully long nights!

Yes! And we have a great range of designs to choose from on http://www.LuxeWaterWalls.com

As someone who likes ambient noise and water, I'd have to say yes. It depends on the occupants and the space, I think.

Any decorative fountain or water wall needs to be properly maintained and kept clean otherwise there is the potential for Legionnaire's disease. I learned this when my aunt passed away from it about 2 years ago. Here's an article I found with a quick google search - not related to my aunt's case. http://www.sciencedaily.com/releases/2012/01/120109145911.htm

Kind of pretty and soothing, but way too much maintenance.

What are the long term effects as far as mold and mildew are concerned?

Everyone knows that water evaporates and condenses. So what are the odds of developing mold from long term use of an indoor waterfall?
