This is a small feature built in a tub. The homeowner wanted something more interesting to look at from their patio. They already have an interesting fire table with makes for a nice mix with all their softscapes. It also features accent lighting (which is controlled with a photovoltaic cell) and an autofill connected to their irrigation. With a switch and remote as options to turn the feature on and off this is very low maintenance and on demand. River flats add even more sound and a continuos but distinct look within the rock bed and give the benefits of a pond less feature.
This is an easy project for a pro install (less than 2 days) but something a homeowner could do with some experience and a few tips. Basalt columns range in size from pop cans to semi loads so you can make a large range of this style bubbler. Mix sizes and number to make them your own.
