Give Your Shower and Tub Their Own Spaces
By: (Page 4 of 4)
Luxury does have its price. In the case of quality whirlpool tubs, prices begin at $700 and
increase depending on the size of the tub, what it's made of and any extras. But there's nothing like a whirl-pool for soaking away stress or soothing aching muscles. Most homeowners are willing to make that investment. A jetted tub was rated a desirable or essential bathroom fixture by 67 percent of respondents in a National Association of Home Builders survey.
The most popular tubs for residential use range from 5 to 7 ft. or more in length and can accommodate one or two people. The number of jets varies from 4 to 12. They should be strategically placed and adjustable for flow; some can be programmed into sequences with different pulse rates and force. The jets are powered by a single-speed 3/4-hp pump or a 3-hp variable-flow unit, or something in between. Other extras include lumbar supports, neck rests and grip bars. Controls should be within reach when you're reclining. Finally, make sure the tub you want "fits" you well—if that great-looking curving style has you sliding down, you're missing the point. Some whirlpools can be used by people with limited mobility; the Kohler Precedence, for instance, offers a side entry and secure door seal.
Whirlpools do pose some design and construction challenges beyond those of a standard tub. Among the issues of which you should be aware:
- Mechanics. Site the tub where the access panel is, well, accessible. Whirlpools come in corner, drop-in and alcove configurations; pick the one that fits your space.
- Weight. A jetted tub might require extra underfloor bracing. If the total load exceeds 30 lbs. per square foot when its in use, you'll probably need to strengthen the framing. Look on the spec sheet for weights.
- Movement and noise. Many pros set whirlpools in plaster of Paris because it helps keep the tub level and steady against pump vibrations. It also muffles motor noise (a rubber motor mount will also help).
- Hot-water supply. The recommended fill level of a two-person jetted tub is 50 to 70 gal., with some models going up to 90 gal. Unless you're partial to bathing in cold water, consider pumping up the capacity of your water heater or opt for a tub that features an inline heating element.
