The home side were nowhere near their best but still did enough to secure a home semi-final against Northampton next weekend.
Chris Ashton, Mako Vunipola and Owen Farrell scored tries for the hosts, with the rest of their points coming from the boot of Farrell.
Rob Webber and Horacio Agulla crossed for Bath, with Tom Heathcote converting both.
