Is the heated SereneLife mat worth the extra $16?

If you take baths longer than about 20 minutes, yes. The PHSPAMT24HT's built-in heater keeps the water warm, which is the main thing the PHSPAMT22 does not clearly do. For short baths, save the money and take the PHSPAMT22.

Which one has better buyer ratings?

The PHSPAMT22, at 3.8 out of 5 from 289 ratings. The PHSPAMT24HT sits at 3.6 from 78 ratings. The gap is small, but the PHSPAMT22 has far more ratings behind its score.

Do both fit a standard bathtub?

Both are 47 inches long and 14.2 inches wide, so they suit a standard tub. Check your tub floor length before buying, since the mat needs to lie flat for the suction cups to hold.

Buyers of the PHSPAMT24HT say its air pump is a bit loud. The PHSPAMT22 uses a motorized air pump too, and its listing gives no noise figure. Expect similar pump noise from either.

Can I use bath salts or bubble bath with them?

The PHSPAMT24HT's buyers warn that bath soap makes bubbles everywhere. Keep soap and salts out of the water, or use very little, with either mat.

Neither listing gives a warranty or a rated lifespan. The PHSPAMT22 has more ratings, which gives a slightly better read on long-term reliability. Both are plastic mats that need hand washing and drying after use.
