Trainer Tower is a place in the Sevii Islands allowing trainers to enjoy different types of battle. It is located north of Seven Island. Similar to the Battle Tower in basic premise, it instead boasts a marathon-type challenge whereby trainers are encourage to fight their way to the top of the tower as quickly as possible. Unlike other battle facilities, trainers are allowed and encouraged to use items - there is even a healing machine on the first floor, though this will certainly waste more time. Like the Battle Tower, money and experience points are not awarded (instead rare evolutionary items after beating the default record of each challenge).
In Japan, players could use e-Reader cards to scan in different trainers, more floors, and potential prizes; this functionality doesn't exist in any other release. Instead, many of the trainers have been brought over as the default, along with the number of floors being bumped to 8.
Lastly, these trainers differ a bit than the usual Battle Tower; that is, their Pokemon all fight at the same level as your highest levelled Pokemon. Some of them are shiny as well, though you don't have to worry about it being random as in other battle facilities.
