A Closer Look at Vinyl Pool Liners
Pools, Semi Inground
When you begin to research purchasing an in-ground swimming pool, there are several types—Gunite (concrete) and Vinyl—are two we carry. Our clients often have questions about how they compare to one another, here is an overview to get you started.
Gunite Pools: Pros and Cons
- As big as you want: Concrete pools can be any size, shape, or depth.
- More flexibility with design features: Vanishing edges, beach entries, tanning ledges and more are possible with concrete pools.
- Works of art: Concrete pools can be integrated into design as a literal work of art in the landscape.
- High lifetime cost: Concrete pools will need to be renovated every 10-20 years. This involves resurfacing and re-tiling the pool at an expense of $8k-$15k or much higher depending on the pool.
- More chemical use: Because the surface of concrete pools is very porous, more chemicals and filtration are required to prevent algae. The alkaline pH of the pool shell also constantly raises the pH of the water, requiring the frequent adding of acid to counteract the effect.
- More maintenance: Concrete pools also need to be frequently broomed or swept with a pool brush to remove algae from the pores of the plaster or aggregate surface.
- Longer install time: Concrete pools take longer to install.
Vinyl Liner Pools: Pros and Cons
- Lower initial cost: Vinyl pools have the lowest initial cost.
- Customizable shape and size: There are no limitations of the length, width, or depth.
- Improved features available: With better technology, popular features like tanning ledges are now available in better quality vinyl liner pools.
- Vinyl liner pools are nonabrasive: The vinyl liner material is smooth to the touch.
- Doesn’t foster algae: The vinyl material used in vinyl liner pools is also relatively non-porous so it inhibits algae growth.
- Higher lifetime cost: On average a vinyl liner will last between 7 and 15 years at a replacement expense of $2,500-$3,500 plus the cost of water.
- Liner warranties pro-rated: Many vinyl liner manufacturers have a 20-year, pro-rated warranty. Make sure you understand the fine print.
- You’ll need to use the pool with care: Dogs, kids throwing stuff in the pool, or tree limbs all have the potential to damage the liner.
- Lower resale value: When you go to sell a home with a vinyl liner pool, your buyer will want to know, “how old is the liner?” If it’s more than 3-4 years old, there’s a good chance a request will be made to replace the liner.
