Here are a few things I haven't seen mentioned but have a significant quality of life improvement for me:
- High quality LED flashlight that can also double as a power bank (e.g. Sofirn BLF SP36, BLF LT1, or Q8 Pro)
- Curved shower bar -- no more fighting or getting stuck on the shower curtain/liner
- Padded mat for in front of the sink, placement depends on where you spent the most time (handwashing dishes, food prep/cooking, etc)
- Over the sink dish rack -- Frees up a ton of counter space if you hand wash
- "Cloud" foam slippers
