Freestanding tubs exude a sense of luxury that built-in tubs simply can't offer. Although they’re a tight fit in cozy apartments or condos, freestanding tubs are a hot trend in larger master baths. Be sure you want to dedicate that kind of real estate to a soaking tub before you pay the top-of-market cost, though. If you don't plan on using the soaking tub every day (or most days) it may become a tripping hazard more than a sensuous oasis. And if you do use it every day? Expect your water bills to rise; the deep walls of these tubs mean they'll use a lot more water than their built-in counterparts.
