Legal Question in Landlord & Tenant Law in California

It depends upon what type of jacuzzi you are talking about. Presuming a device placed into the bathtub that is hooked up to the water spigot, at least the following must be considered: must a plumber do the attachment so as to prevent the likelihood of a failure resulting in water being sprayed around the entire bathroom, who owns the jacuzzi when the tenant lives as it could possibly be considered attached to the tub so now part of the real property, how will any damage to the tub be avoided, if the landlord pays for water or heat will there be an increase the tenant is charged because of greater useage of either, if there are multiple rental units does its operation cause noise so that the hours of use must be regulated, whose obligation is it to fix it, etc.
