I also had difficulty sourcing. I used a couple of apps to do so, here's the final playlist:
EquipmentSupplierCost

Spa lightFlorida Sunseeker$497
Pentair CCP520 filterFB Marketplace (used)$400
Flowvis FV-2Amazon$112
Pentair IntellifloAmazon$1802

Pentair IntelliValveAZPoolSupplies.com$215/ea
Pentair 200k MasterTempAZPoolSupplies.com$2171
Air Supply Silencer (spa blower)FB Marketplace (NOS)$126

I didn't list the white goods, because they were generally easier to find. There were also way more options in white good suppliers (although, I used 95% CMP).
Thank you.

Tiling has started, which I'll be posting an update on once completed. But we've run into an issue.

In some areas, the spa venturi's are closer to inside wall - leaving only ~1/2" between the front of the niche and gunite wall. The venturi niche itself is ~2" long. Even at the shortest length, I would need to add nearly 2" to the gunite wall. Looking for ideas/advise.

I didn't take any pictures, but we fixed the spa. TL;DR: Installed metal lathe, and built-up mortar a few inches, then waterproofed again.

Timeline
  • Total = 2d
  • 1 day mortar
  • 1 day waterproof
Technical
  • Started with a string layout giving the minimum increase in wall thickness (the greatest build-up was about 2").
  • I cut-down the spa plumbing and installed the niche's, so we knew the min. final thickness.
  • Since we already waterproofed, we added metal lathe to give the new mortar something to grab. Ramset the lathe into the wall.
  • We then did a scratch coat of mortar.
  • We then began building up the mortar thickness moving from wall-to-wall until we got to the desired thickness on each wall.
  • After dried, we waterproofed. It turned out very nicely, and smoothed in quite well.
Costs
  • Total = $182
  • Metal lathe
  • 1" ramset fasteners w/ washers
  • Rapid-set mortar (up to $18/55lb bag!)
Lessons Learned/Comments
  • Don't make my mistake - double-check your spa plumbing dims after rebar is complete, prior to gunite.

Gas feeder was completed mid-March. I stubbed-up the outlet near the equipment pad, and capped the line.
Timeline
  • Total = 1d
Technical
  • I used a common trench for many utilities - my workshop subpanel feeder (2" conduit), pool heater gas feeder (1"), pool plumbing return loop (2"), and stormwater from my gutters (4"). I aimed for 32" depth and 6" wide, which put the important items (electrical and gas) well below 18" (to top of pipe).
  • These utilities can share a common trench, but if you run supply & sewage you must take different precautions.
  • IPS (plastic) pipe used for the majority of the ~75ft run. Heater required 1", and by my calcs I may be ever-so-slightly undersized (gamble).
  • The gas needs to be shut off, and allowed to evacuate, prior to work.
  • Tapped into an existing 1" main, and added a union. Converted to the IPS, and wrapped it in tracer wire. Leak-checked at 10psig for an hour - found a leak at an IPS fitting which had to be replaced. Repeated until no leaking.
  • Taped exposed metal portions with corrosion-preventative tape, inspected, backfilled. Left gas OFF until final heater connections.
Cost
  • Total = $459
  • 1" IPS pipe and fittings = $262
  • NG pipe dope, corrosion tape, tracer wire, and pressure gauge = $36
  • Black Iron fittings to connect to existing line = $161
Lessons Learned/Concerns
  • My pressure gauge leaked at a fitting that wasn't repairable. It took a long time to diagnose this failure, and I lost many hours doing leak-detection. There were no tell-tale signs of the failure. I had to build a replacement leak-tester last-minute.
