Hire a company, It is very involved.

Although this project can be done as a diy project, to complete it successfully, you will need all the necessary specific tools and materials and a minimum amount of previous experience in using them correctly. Proper quality materials are not inexpensive, and you will need to buy extra to allow for breakage, cutting wastage, and needed second applications and touchups.

As for the time estimated to complete the project, start to finish, one weekend is very over-rated. These time estimates seldom take into calculation the time needed for set up, removal of debris, cleaning, dryfitting of pieces, and double measuring. The work will involve plumbing, carpentry, construction, tiling, and probably drywall, and flooring finishing.

While it can be rewarding, if you are serious about doing all the labour yourself, my suggestion is to first take some workshops on the procedures.
