I'm a natural hot springs fan...one with a nice view is even better
Where do you find hot springs in Colorado? I don't think we have them in New York.
I for one do not know the difference between the different types. I'm curious about the price difference and pros and cons of each.
We have quite a few here in Colorado as well as in neighboring states like New Mexico, Wyoming..(can you say Yellowstone). In Colorado one of my Favorites is Strawberry park near Steamboat Springs, we have also enjoyed the one about 20 miles from our cabin in NM. It is located along the banks of the Rio Grand.
I'm with Miriam, except I do know I wouldn't like concrete. I remember too many stubbed toes and scrapes from concrete pools. We used to have an above ground pool (18 ft.) and seemed like all we did was clean and shock it. Soon as the kids started jobs, we pulled it out and built a sunroom and upstairs laundry where the decking used to be! Then 5 yrs. later, we sold the house. Missed the pool, but not the maintenance!
The short answer is- In the past, to get a a truly custom shape with unusual features like benches,custom stairs, deep end stairs, swim outs, bar stools, vanishing edges, custom vinyl spas etc. you had to get a concrete (aka gunite, shotcrete) pool. Typically they were much more expensive than other pools and out of reach for most people. Now due to technology, vinyl liner pools can be built with these unusual features because the liners and be made to fit any size or shape pool and pool feature. These vinyl pools are often built with steel or poured concrete wall for strength and lined with the vinyl liner.
Vinyl liner pools- Are a wall system (usually concrete or steel walls) troweled sand or hard bottoms floors and a vinyl liner installed within the walls. The liner holds the water.
Concrete pools- are usually dug to the shape of the pool, steel rebars are installed within that shape and then "shot" with shotcrete. Shotcrete is usually moist concrete blasted though a hose at ahigh rate of speed onto the steel bars and about 6" - 8" thick to create the pool. after shotcrete the pool is usually waterproofed, and than a smooth or "pebble" finish is applied. This full concrete shell is the pool and holds the water.
Fiberglass pools- are pools that are built in a factory, using a mold. The pool shapes are predetermined, and you can pick your shape from a catalog. The pools are manufactured and shipped over the road to it's final location where they are craned off of the truck and dropped into position in your yard.
A natural ecosystem swimming pond- is made by excavating the shape of your pond, installing a rubber (or other type of) liner, installing a circulation system, waterfall, skimmer etc, and using natural elements (beneficial bacteria, waterplants, etc) to circulate and clean your pond.
These descriptions are somewhat general, each pool have it's benefits, and could be the bast fit for you.
If you have any question about pools or ponds, I'd be happy to answer!
