All it really has to do is hold hot water and people. The people using the tub also leave dirt and oils in the water. That feeds bacteria, which can make the tub smell bad and even harm the health of bathers. You could replace the water every few times you use it, but heating the water is expensive. You also need a filtration system and anti-bacterial chemicals.

These can be found in either rubberized plastic or galvanized steel. The size and shape you choose will depend on how and who will be using it. A thin narrow tank is better for solo soaking, because they are easier to heat and use less water. A round tank works better for when multiple people will be using the tub at the same time. If you are handy with the tools and insist that the finished product look high-end rather than strictly functional, you can choose to make the tub yourself out of wood.

The whole unit sits in the water, which allows the entire surface of the sides to transfer heat to the water.
An external burner sits, as the name suggests, outside your tub. It works by piping water from the tub, through pipes that are heated by the fire, and then back into the tub.
When properly built, the water circulates through the system by convection. The cover guy recommends that you purchase a specially built wood-fired hot tub heater rather than attempting to build your own from scratch.
Using the tub once a day, you can generally expect to drain and refill the tub every week or so. Many people who have switched to a wood burner say that what they really like about them is the sense of ritual involved in their use.
