While a freestanding tub can be a bit more difficult to install than a built-in tub, if you have moderate plumbing skills, you shouldn’t encounter too many problems. One of the more trying elements includes hauling the tub into place, but there are some precautions you can take to ease the process.First, carefully measure the room where the tub will go. The room should fit the tub with an additional several inches between the tub and any walls (recommended space varies between 4 and 12 inches). You should also leave enough room to install and maintain the plumbing.Next, measure all doors, hallways, and staircases through which you need to move the tub. This is particularly important if you’re installing it above or below the ground floor.;Finally, be sure that any floor you place the tub on can support the weight of the tub plus water plus you. This is particularly important if you buy a tub made of stone or cast iron.
