I will be starting my pool in the next 3-4 weeks (and will post pic's once the plan is finalized).
A fairly significant portion of "upgrade" costs is due to the interior finish.
For those of you who have had quartz and pebble for more than 5 years -
Are you happy with the product?
Has it lived up to your expectations?
How much longer do you think it will last before a "replaster" is required?
