Think whirlpool spas are all about bubbles (that soothing way to relax and soak away troubles?) Today you'll learn that, spa-wise, there's more to be seen...including today's sparkling Irish green! Indeed, ?watercolors? are here in the form of variable underwater lighting called chromatherapy. Now, while you soak amid warming effervescent bubbles, underwater lenses cast a soothing glow of color that slowly changes throughout the spectrum. Should you find a hue you especially like, you can command it to ?hold? with the tub's unique floating remote that also controls the intensity of the water jets. The ?sok? bath with chromatherapy by Kohler costs about $7,400. That a bit more than you can pay? Well, today (and today only!) you may have a temporary low-cost option. For a soothing, bubbling tub ?full o? green?, just fill your tub with today's colorful beer, and ?Erin go bathing!!?
