- What pipes you need: Sometimes you need new fittings or connections

- Access: Hard-to-reach spots take longer
Most installations take a few minutes to an hour depending where you will be installing it. It's basically mount it, pipe it, and plug it in and if you’ve the necessary supplies for installation.

System Size: Bigger homes need bigger systems. A small 2-bedroom place might be fine with a basic system, while a large family home needs something with more grunt.
Water Quality: If your water is really dirty or has lots of sediment, you might need extra pre-filters. This adds to both the system cost and complexity.
Location: Installing outside is usually cheaper because plumbers don't need to worry about water spillage. Indoor installations sometimes need extra protection or drainage.
Electrical Work: Most systems just plug into a normal power outlet, but if you need new electrical work, that's extra cost.
