Pool Surface
The pool has a fiberglass surface, likely installed in an attempt to seal leaks in the underlying gunite shell. However, significant structural issues are evident. There is noticeable movement and unevenness around the pool — approximately 2 inches of depth difference from the top of the tile on one side compared to the other, with more than 1 inch of variation from the southwest to the northeast side. This indicates the gunite shell is compromised and has shifted.
The fiberglass surface itself shows peeling and cracking, particularly at the bottom of the pool and on the steps, with additional blemishes scattered throughout. These issues are likely worsened by prolonged dry periods, sun exposure, and temperature fluctuations.
Given the shell movement, abandoned copper plumbing lines (two of five already abandoned), and multiple leaks, the underlying structure appears severely compromised. Surface repairs or a simple resurfacing would not address the root problem. This is likely a complete remodel situation requiring removal and replacement of the gunite shell.
Exact costs for full shell replacement are difficult to determine without further evaluation. A rough estimate would be $20,000 to $40,000 or more. I recommend consulting a general contractor or structural pool specialist for a detailed assessment before considering any surface work.
Cost summary (this section only)
• Full gunite shell replacement + remodel (rough estimate): $20,000–$40,000+
• Fiberglass surface replacement (if pursued after shell work): not estimated here (additional cost)

Waterline Tile & Surrounding Concrete
The waterline tile appears unfinished. It looks like the tile was simply glued on without proper grout or additional product pushed between the tiles, leaving crevices where organic matter can build up.
Gaps are also present in multiple locations between the concrete coping and the tile.
The cost to remedy the waterline tile issues (grouting the gaps and sealing) would likely run less than $1,000.
Additionally, the concrete around the pool coping needs attention. There are trip and injury hazards around almost the entire perimeter. To extend the life of the current concrete, recommend grinding the high spots and filling with mastic. This would cost less than $3,000, which is substantially cheaper than replacing all the concrete and coping ($5,000–$10,000, likely closer to $10,000).
The skimmer throat is compromised with cracks and issues. The entire skimmer will likely need to be redone at a cost of $3,000–$5,000 (likely closer to $5,000).
Cost summary (this section only)
• Waterline tile grouting and gap repair: <$1,000
• Concrete coping grinding and mastic fill: <$3,000
• Full skimmer replacement: $3,000–$5,000 (likely closer to $5,000)
• Full concrete and coping replacement (if pursued): $5,000–$10,000

Water Quality
Water quality is due for minor adjustments. Cyanuric acid and calcium hardness levels are both low, indicating relatively new water. The auto fill is actively compensating, suggesting ongoing water loss is present.
Estimated cost for chemicals to balance pH, alkalinity, CYA, calcium hardness, and chlorine: ~$200 or less.
However, due to the active water loss, much of this treatment may be money down the drain until the leaks are addressed.
Cost summary (this section only)
• Water balancing chemicals: ~$200 or less

Main Drain
The main drain has been abandoned (filled in or removed).
A suction-side bottom cleaner is currently performing a similar function, though at a much lower flow rate of about 30 gallons per minute compared to a typical main drain (100–200 GPM depending on size and number).
Replacing the main drain is not needed at this moment. If pursued later, it would require jackhammering the main drain section and running new plumbing up the side of the pool to the skimmer area. Cost would likely run $5,000–$10,000 (closer to $5,000).
However, until the pool shell leveling issue is resolved, replacing the main drain would be a moot point.
Cost summary (this section only)
• Main drain replacement (if pursued later): $5,000–$10,000 (likely closer to $5,000)

Skimmer
The skimmer shows signs of past leak repairs and movement.
It is likely due for replacement. Cost to replace the skimmer (including related work): $3,000–$5,000.
The skimmer has been diverted to support the bottom cleaner, which is currently functioning.
Cost summary (this section only)
• Skimmer replacement: $3,000–$5,000

Near new - working well just needs one more hose section ($25).

The float that’s currently connected to The Pool likely needs minor service or attention to resolve water loss from the hose to auto fill connection - hose rubber gasket

The filter is older but still working without issue seen at this time. Rec servicing inside the filter to confirm due to age and condition, at this time all that is seen is the need for a new pressure gauge ($50 liquid filled) but may need a new element ($100) + misc parts ($100) ie o rings soon.

Note a new much better filter is the Aqua Star Pipeline Filter 35000 = $800.

This pump is near new, with a mouse found in the basket (odd as there is an in line leaf basket in place for the bottom cleaner - its almost as if the mouse got IN the pump from another source (?!) still a small leak is found on the drain plug o ring - easy fix = $50 or less

Board and Timer
The board and timer are connected with non-code-approved soft Romex-style wire run outside of any conduit. This is unsafe and should be corrected.
The proper fix is to run new, appropriately sized wire from the main panel to the pool equipment, placed inside conduit, and install a subpanel with proper GFCI breakers.
Estimated cost for an electrician to complete this work: $500–$750.
At the same time, consider updating the timer if desired.
Cost summary (this section only)
• Wiring, conduit, and GFCI subpanel upgrade: $500–$750
• Timer update (optional): not estimated

Leak free, working. Copper to
PVC on returns and suction side pvc seen.
