Four get their own page because there is more to getting them right: hot tub steps (match the height to your tub), hot tub covers (how to measure and when to replace), cover lifts (which type fits your clearance), and gazebos and enclosures (how big the roof over the tub needs to be).

What is actually worth it
Spend first on the things that affect safety and running cost: solid steps and a grab rail so nobody slips, and a tight, dry cover plus a cover lift, since the cover is the single biggest lever on your power bill. Comfort extras like pillows, lights, and spa-safe aromatherapy are cheap and genuinely nice. Skip anything that goes in the water but is not made for a spa, since household oils and scents foam the water and clog the filter.
