When deciding what type of pool would suit you best there are many considerations: frequency of use of the pool, lifestyle and maintenance options, local climate, site-specific considerations, pool deck options, desired copings, and pool depths. Gunite, simply stated, is a concrete pool. Gunite pools are more expensive to install and slightly more to maintain over the years. Vinyl liner pools are generally less expensive to repair and maintain. However in areas with excessive water tables a gunite pool is generally recommended vs. a vinyl liner pool.
