Without lighting, using your pool after dusk is difficult. It's easy to add subsurface lighting to your pool if you have the electrical lines. This will cost around $900. Upgrades like dimmable or color changing lights can be made.
The plaster's plaster coating and/or surface may become less durable over time. Depending on your region, you may need to treat your pool every ten years or more. First, spalling and cracks must be fixed. Then the pool shell needs to be prepped. The prep will remove all plaster and make the surface rougher so that new layers can bond to it. The prep is done with a variety of techniques, including chipping, chemical surface engraving, and sandblasting.
Accent tiling may be the best option for those who want to save money when tiling. You can make a striking statement by laying tile around the edges and finishing the pool's underside with paint or plaster.
