Following the expansion plan of the 1980s, Plymouth Harbor continued to make updates throughout the campus in the years to come.
Beginning with the installation of solar heating for the outdoor pool in 1992, updates to existing amenities and technology became a main focus. In 1993, Pilgrim Hall received a home theater system and an updated PA system. In 1994, the Plymouth Harbor Dining Room was completely redone with a $1.2 million renovation. Additionally, Channel 58 (now known to residents as Channel 195) was installed as an in-house TV station to keep residents updated on events and activities occurring at Plymouth Harbor.
