SereneLife PHSPAMT24HT Bubble Spa Mat vs Medisana Bubble Mat BBS

Buy the SereneLife if you want a bubble mat with a built-in heater, a remote and a strong air pump; it is the better-known option and owners say it feels like a real jacuzzi. The Medisana Bubble Mat Bbs is the quieter, more controlled pick with three bubble levels and four heat levels, but it has little owner feedback and no track record in US tubs. Both are plastic mats that sit on suction cups, so neither is a built-in whirlpool.

• Choose the SereneLife PHSPAMT24HT if you want a heated bubble mat with a remote, auto shut-off and a pump owners call stronger than the Homedics versions.
• Choose the Medisana Bubble Mat Bbs if you want more heat settings and a 570 W unit from a German health-device brand, and you don't mind sparse owner reviews.
