If you are familiar with the techniques of plumbing, you can install a soaking tub by yourself, but you always need some assistance because soaking tubs are heavy, and installation of a tub is never a one-person job. It is always better to get a soaking tub installed by a professional. Some models, like drop-in tubs, need proper fixing and cementing. The drainage system also needs to be taken care of, so it is always safe to get some help to install your soaking tub.
