Affordable Air Bath. Mansfield Plumbing Products recently added a line of air baths to its Pro-Fit collection of whirlpools and soaker tubs. Air baths typically cost more than whirlpools but — according to manufacturers — produce a gentler massage and feature a more hygienic drainage system. Pro-Fit Air Baths come in eight sizes.

Prices start at $1,380. Mansfield Plumbing Products, 800/999-1459, mansfieldplumbing.com
